Abstract

This document describes how to deploy a Red Hat Decision Manager 7.3 immutable server environment on Red Hat OpenShift Container Platform.

Preface

As a system engineer, you can deploy a Red Hat Decision Manager immutable server environment on Red Hat OpenShift Container Platform to provide an infrastructure to execute services and other business assets. You can use standard integration tools to manage the immutable Decision Server image. You can create new server images to add and update the business assets.

Prerequisites

  • At least two gigabytes of memory must be available in the OpenShift cluster/namespace.
  • The OpenShift project for the deployment must be created.
  • You must be logged in to the project using the oc command. For more information about the oc command-line tool, see the OpenShift CLI Reference. If you want to use the OpenShift Web console to deploy templates, you must also be logged on using the Web console.

Chapter 1. Overview of Red Hat Decision Manager on Red Hat OpenShift Container Platform

You can deploy Red Hat Decision Manager into a Red Hat OpenShift Container Platform environment.

In this solution, components of Red Hat Decision Manager are deployed as separate OpenShift pods. You can scale each of the pods up and down individually, providing as few or as many containers as necessary for a particular component. You can use standard OpenShift methods to manage the pods and balance the load.

The following key components of Red Hat Decision Manager are available on OpenShift:

  • Decision Server, also known as Execution Server or KIE Server, is the infrastructure element that runs decision services and other deployable assets (collectively referred to as services) . All logic of the services runs on execution servers.

    You can freely scale up a Decision Server pod, providing as many copies as necessary, running on the same host or different hosts. As you scale a pod up or down, all its copies run the same services. OpenShift provides load balancing and a request can be handled by any of the pods.

    You can deploy a separate Decision Server pod to run a different group of services. That pod can also be scaled up or down. You can have as many separate replicated Decision Server pods as necessary.

  • Business Central is a web-based interactive environment for authoring services. It also provides a management console. You can use Business Central to develop services and deploy them to Decision Servers.

    Business Central is a centralized application. However, you can configure it for high availability, where multiple pods run and share the same data.

    Business Central includes a Git repository that holds the source for the services that you develop on it. It also includes a built-in Maven repository. Depending on configuration, Business Central can place the compiled services (KJAR files) into the built-in Maven repository or (if configured) into an external Maven repository.

    Important

    In the current version, high-availability Business Central functionality is for Technology Preview only. For more information on Red Hat Technology Preview features, see Technology Preview Features Scope.

You can arrange these and other components into various environment configurations within OpenShift.

The following environment types are typical:

  • Authoring or managed environment: An environment architecture that can be used for creating and modifying services using Business Central and also for running services on Decision Servers. It consists of pods that provide Business Central for the authoring work and one or more Decision Servers for execution of the services. Each Decision Server is a pod that you can replicate by scaling it up or down as necessary. You can deploy and undeploy services on each Decision Server using Business Central. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager authoring or managed server environment on Red Hat OpenShift Container Platform.
  • Deployment with immutable servers: An alternate environment for running existing services for staging and production purposes. In this environment, when you deploy a Decision Server pod, it builds an image that loads and starts a service or group of services. You cannot stop any service on the pod or add any new service to the pod. If you want to use another version of a service or modify the configuration in any other way, you deploy a new server image and displace the old one. In this system, the Decision Server runs like any other pod on the OpenShift environment; you can use any container-based integration workflows and do not need to use any other tools to manage the pods. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager immutable server environment on Red Hat OpenShift Container Platform.

You can also deploy a trial or evaluation environment. This environment includes Business Central and a Decision Server. You can set it up quickly and use it to evaluate or demonstrate developing and running assets. However, the environment does not use any persistent storage, and any work you do in the environment is not saved. For instructions about deploying this environment, see Deploying a Red Hat Decision Manager trial environment on Red Hat OpenShift Container Platform.

To deploy a Red Hat Decision Manager environment on OpenShift, you can use the templates that are provided with Red Hat Decision Manager.

Chapter 2. Preparing to deploy Red Hat Decision Manager in your OpenShift environment

Before deploying Red Hat Decision Manager in your OpenShift environment, you need to complete several preparatory tasks. You do not need to repeat these tasks if you want to deploy additional images, for example, for new versions of decision services or for other decision services

2.1. Ensuring the availability of image streams and the image registry

To deploy Red Hat Decision Manager components on Red Hat OpenShift Container Platform, you must ensure that OpenShift can download the correct images from the Red Hat registry. To download the images, OpenShift requires the information about their location (known as image streams). OpenShift also must be configured to authenticate with the Red Hat registry using your service account user name and password.

Some versions of the OpenShift environment include the required image streams. You must check if they are available. If image streams are available in OpenShift by default, you can use them if the OpenShift infrastructure is configured for registry authentication server. The administrator must complete the registry authentication configuration when installing the OpenShift environment.

Otherwise, you can configure registry authentication in your own project and install the image streams in the same project.

Procedure

  1. Determine whether Red Hat OpenShift Container Platform is configured with the user name and password for Red Hat registry access. For details about the required configuration, see Configuring a Registry Location. If you are using an OpenShift Online subscription, it is configured for Red Hat registry access.

  2. If Red Hat OpenShift Container Platform is configured with the user name and password for Red Hat registry access, run the following commands: 

    $ oc get imagestreamtag -n openshift | grep rhdm73-decisioncentral-openshift
$ oc get imagestreamtag -n openshift | grep rhdm73-kieserver-openshift

    If the outputs of both commands are not empty, the required image streams are available in the openshift namespace and no further action is required.

  3. If the output of one or both of the commands is empty or if OpenShift is not configured with the user name and password for Red Hat registry access, complete the following steps:

    1. Ensure you are logged in to OpenShift with the oc command and that your project is active.
    2. Complete the steps documented in Registry Service Accounts for Shared Environments. You must log in to Red Hat Customer Portal to access the document and to complete the steps to create a registry service account.
    3. Select the OpenShift Secret tab and click the link under Download secret to download the YAML secret file.
    4. View the downloaded file and note the name that is listed in the name: entry.

    5. Run the following commands: 

      oc create -f <file_name>.yaml
oc secrets link default <secret_name> --for=pull
oc secrets link builder <secret_name> --for=pull

      Where <file_name> is the name of the downloaded file and <secret_name> is the name that is listed in the name: entry of the file.

    6. Download the rhdm-7.3.0-openshift-templates.zip product deliverable file from the Software Downloads page and extract the rhdm73-image-streams.yaml file.

    7. Complete one of the following actions:

      • Run the following command: 

        $ oc create -f rhdm73-image-streams.yaml

      • Using the OpenShift Web UI, select Add to Project → Import YAML / JSON and then choose the file or paste its contents.

        Note

        If you complete these steps, you install the image streams into the namespace of your project. If you install the image streams using these steps, you must set the IMAGE_STREAM_NAMESPACE parameter to the name of this project when deploying templates.

2.2. Creating the secrets for Decision Server

OpenShift uses objects called Secrets to hold sensitive information, such as passwords or keystores. For more information about OpenShift secrets, see the Secrets chapter in the OpenShift documentation.

You must create an SSL certificate for Decision Server and provide it to your OpenShift environment as a secret.

Procedure

  1. Generate an SSL keystore with a private and public key for SSL encryption for Decision Server. In a production environment, generate a valid signed certificate that matches the expected URL of the Decision Server. Save the keystore in a file named keystore.jks. Record the name of the certificate and the password of the keystore file.

    For more information on how to create a keystore with self-signed or purchased SSL certificates, see Generate a SSL Encryption Key and Certificate.

  2. Use the oc command to generate a secret named kieserver-app-secret from the new keystore file: 

    $ oc create secret generic kieserver-app-secret --from-file=keystore.jks

2.3. Extracting the source code from Business Central for use in an S2I build

If you are using Business Central for authoring services, you can extract the source code for your service and place it into a separate Git repository (such as GitHub or an on-premise installation of GitLab) for use in the S2I build.

Procedure

  1. Use the following command to extract the source code: 

    git clone ssh://adminUser@decision-central-host:8001/MySpace/MyProject

    Replace:

    • adminUser with the administrative user for Business Central
    • decision-central-host with the host on which Business Central is running
    • MySpace with the name of the Business Central space in which the project is located
    • MyProject with the name of the project
  2. Upload the source code to another Git repository for the S2I build.

2.4. Preparing a Maven mirror repository for offline use

If your Red Hat OpenShift Container Platform environment does not have outgoing access to the public Internet, you must prepare a Maven repository with a mirror of all the necessary artifacts and make this repository available to your environment.

Skip this procedure if your Red Hat OpenShift Container Platform environment is connected to the Internet.

Procedure

  1. Prepare a Maven release repository to which you can write. The repository must allow read access without authentication. Your OpenShift environment must have access to this repository. You can deploy a Nexus repository manager in the OpenShift environment. For instructions about setting up Nexus on OpenShift, see Setting up Nexus.

  2. Complete the following actions on a computer that has an outgoing connection to the public Internet:

    1. Clear the local Maven cache directory (~/.m2/repository).
    2. Build the source of your services using the mvn clean install command.
    3. Upload all artifacts from the local Maven cache directory (~/.m2/repository) to the Maven repository that you prepared. You can use the Maven Repository Provisioner utility to upload the artifacts.

Chapter 3. Environment with immutable servers

You can deploy an environment that includes one or more pods running Decision Server with preloaded services. Each Decision Server pod can be separately scaled as necessary.

In this case, any services (KJAR files) must be loaded onto a Decision Server at the time the image is created. You cannot load or unload services on a running Decision Server. The advantage of this approach is that the Decision Server with the services in it runs like any other containerized service and does not require specialized management. The Decision Server runs like any other pod on the OpenShift environment; you can use any container-based integration workflows as necessary.

When you create a Decision Server image, you can build your services using S2I (Source to Image). Provide a Git repository with the source of your services and other business assets; if you develop the services or assets in Business Central, copy the source into a separate repository for the S2I build. OpenShift automatically builds the source, installs the services into the Decision Server image, and starts the containers with the services.

If you are using Business Central for authoring services, you can extract the source for your process and place it into a separate Git repository (such as GitHub or an on-premise installation of GitLab) for use in the S2I build.

Alternatively, you can create a similar Decision Server deployment using services that are already built as KJAR files. In this case, you must provide the services in a Maven repository; you can use the built-in repository of the Business Central or your own repository (for example, a Nexus deployment). The KJAR files are retrieved from the Maven repository during the startup of the pod and not updated or changed after that. The files are retrieved at every restart or scaling of the pod, so you must ensure they do not change on the Maven repository to keep the deployment immutable.

With both methods of creating immutable images, no further management of the image is required. If you want to use a new version of a service, you can build a new image.

3.1. Deploying an immutable Decision Server from service source code

To deploy an immutable Decision Server from service source code, use the rhdm73-prod-immutable-kieserver.yaml template file. You can extract this file from the rhdm-7.3.0-openshift-templates.zip product deliverable file. You can download the file from the Software Downloads page.

When you deploy an immutable Decision Server, the deployment procedure retrieves the source code for any services that must run on this server, builds the services, and includes them in the server image.

Procedure

  1. Use one of the following methods to deploy the template:

    • In the OpenShift Web UI, select Add to Project → Import YAML / JSON and then select or paste the rhdm73-prod-immutable-kieserver.yaml file. In the Add Template window, ensure Process the template is selected and click Continue.

    • To use the OpenShift command line console, prepare the following command line: 

      oc new-app -f <template-path>/rhdm73-prod-immutable-kieserver.yaml -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret

      In this command line:

      • Replace <template-path> with the path to the downloaded template file.
      • Use as many -p PARAMETER=value pairs as needed to set the required parameters. You can view the template file to see descriptions for all parameters.

  2. Set the following parameters as necessary:

    • KIE Server Keystore Secret Name (KIE_SERVER_HTTPS_SECRET): The name of the secret for Decision Server, as created in Section 2.2, “Creating the secrets for Decision Server”.
    • Application Name (APPLICATION_NAME): The name of the OpenShift application. It is used in the default URL for Decision Server. OpenShift uses the application name to create a separate set of deployment configurations, services, routes, labels, and artifacts. You can deploy several applications using the same template into the same project, as long as you use different application names. Also, the application name determines the name of the server configuration (server template) on the Business Central that the Decision Server is to join. If you are deploying several Decision Servers, you must ensure each of the servers has a different application name.
    • KIE Server Certificate Name (KIE_SERVER_HTTPS_NAME): The name of the certificate in the keystore that you created in Section 2.2, “Creating the secrets for Decision Server”.
    • KIE Server Keystore Password (KIE_SERVER_HTTPS_PASSWORD): The password for the keystore that you created in Section 2.2, “Creating the secrets for Decision Server”.
    • KIE Server Container Deployment (KIE_SERVER_CONTAINER_DEPLOYMENT): The identifying information of the decision service (KJAR file) that is built from your source. The format is: <containerId>=<groupId>:<artifactId>:<version>. You can provide two or more KJAR files using the | separator, for example: containerId=groupId:artifactId:version|c2=g2:a2:v2. The Maven build process must produce all these files from the source in the Git repository.
    • Git Repository URL (SOURCE_REPOSITORY_URL): The URL for the Git repository that contains the source for your decision service.
    • Git Reference (SOURCE_REPOSITORY_REF): The branch in the Git repository
    • Context Directory (CONTEXT_DIR): The path to the source within the project downloaded from the Git repository
    • Artifact Directory (ARTIFACT_DIR): The path within the project that contains the required binary files (KJAR files and any other necessary files) after a successful Maven build. Normally this directory is the target directory of the build. However, you can provide prebuilt binaries in this directory in the Git repository
    • ImageStream Namespace (IMAGE_STREAM_NAMESPACE): The namespace where the image streams are available. If the image streams were already available in your OpenShift environment (see Section 2.1, “Ensuring the availability of image streams and the image registry”), the namespace is openshift. If you have installed the image streams file, the namespace is the name of the OpenShift project.

  3. If your build includes dependencies that are not available on the public Maven tree and require a separate repository, set the parameters to provide this repository:

    • Maven repository URL (MAVEN_REPO_URL): The URL for the Maven repository.
    • Maven repository username (MAVEN_REPO_USERNAME): The username for the Maven repository.
    • Maven repository password (MAVEN_REPO_PASSWORD): The password for the Maven repository.

  4. If your OpenShift environment does not have outgoing access to the public Internet, set the following parameters:

    • Maven mirror URL (MAVEN_MIRROR_URL): The URL for the Maven mirror repository that you set up in Section 2.4, “Preparing a Maven mirror repository for offline use”. This URL must be accessible from a pod in your OpenShift environment.

    • Maven mirror of (MAVEN_MIRROR_OF): The Maven mirrorOf value that determines which artifacts are to be retrieved from the mirror. For instructions about setting the mirrorOf value, see Mirror Settings in the Apache Maven documentation. The default value is external:*. With this value, Maven retrieves every required artifact from the mirror and does not query any other repositories.

      • If you configure an external Maven repository (MAVEN_REPO_URL), change MAVEN_MIRROR_OF to exclude the artifacts in this repository from the mirror, for example, external:*,!repo-custom. Replace repo-custom with the ID that you configured in MAVEN_REPO_ID.
      • If you configure a built-in Business Central Maven repository (BUSINESS_CENTRAL_MAVEN_SERVICE), change MAVEN_MIRROR_OF to exclude the artifacts in this repository from the mirror: external:*,!repo-rhdmcentr.

      • If you configure both repositories, change MAVEN_MIRROR_OF to exclude the artifacts in both repositories from the mirror: external:*,!repo-rhdmcentr,!repo-custom. Replace repo-custom with the ID that you configured in MAVEN_REPO_ID.

        +

  5. If you want to use RH-SSO or LDAP authentication, complete the following additional configuration. Do not configure LDAP authentication and RH-SSO authentication in the same deployment.

    1. In the RH-SSO or LDAP service, create all user names in the deployment parameters. If you do not set any of the parameters, create users with the default user names. The created users must also be assigned to roles:

      • KIE_ADMIN_USER: default user name adminUser, roles: kie-server,rest-all,admin
      • KIE_SERVER_USER: default user name executionUser, roles kie-server,rest-all,guest

    2. If you want to configure Red Hat Single Sign On (RH-SSO) authentication, an RH-SSO realm that applies to Red Hat Decision Manager must exist. A client within RH-SSO must also exist for

      For the user roles that you can configure in RH-SSO, see Roles and users.

      Use one of the following procedures:

      1. If the client for Red Hat Decision Manager within RH-SSO already exists, set the following parameters in the template:

        • RH-SSO URL (SSO_URL): The URL for RH-SSO.
        • RH-SSO Realm name (SSO_REALM): The RH-SSO realm for Red Hat Decision Manager.
        • KIE Server RH-SSO Client name (KIE_SERVER_SSO_CLIENT): The RH-SSO client name for Decision Server.
        • KIE Server RH-SSO Client Secret (KIE_SERVER_SSO_SECRET): The secret string that is set in RH-SSO for the client for Decision Server.
        • RH-SSO Disable SSL Certificate Validation (SSO_DISABLE_SSL_CERTIFICATE_VALIDATION): Set to true if your RH-SSO installation does not use a valid HTTPS certificate.

      2. To create the client for Red Hat Decision Manager within RH-SSO, set the following parameters in the template:

        • RH-SSO URL (SSO_URL): The URL for RH-SSO.
        • RH-SSO Realm name (SSO_REALM): The RH-SSO realm for Red Hat Decision Manager.
        • KIE Server RH-SSO Client name (KIE_SERVER_SSO_CLIENT): The name of the client to create in RH-SSO for Decision Server.
        • KIE Server RH-SSO Client Secret (KIE_SERVER_SSO_SECRET): The secret string to set in RH-SSO for the client for Decision Server.
        • KIE Server Custom http Route Hostname (KIE_SERVER_HOSTNAME_HTTP): The fully qualified host name to use for the HTTP endpoint for Decision Server. If you need to create a client in RH-SSO, you can not leave this parameter blank.
        • KIE Server Custom https Route Hostname (KIE_SERVER_HOSTNAME_HTTPS): The fully qualified host name to use for the HTTPS endpoint for Decision Server. If you need to create a client in RH-SSO, you can not leave this parameter blank.
        • RH-SSO Realm Admin Username (SSO_USERNAME) and RH-SSO Realm Admin Password (SSO_PASSWORD): The user name and password for the realm administrator user for the RH-SSO realm for Red Hat Decision Manager.
        • RH-SSO Disable SSL Certificate Validation (SSO_DISABLE_SSL_CERTIFICATE_VALIDATION): Set to true if your RH-SSO installation does not use a valid HTTPS certificate.

    3. To configure LDAP, set the AUTH_LDAP* parameters of the template. These parameters correspond to the settings of the LdapExtended Login module of Red Hat JBoss EAP. For instructions about using these settings, see LdapExtended Login Module.

      If the LDAP server does not define all the roles required for your deployment, you can map LDAP groups to Red Hat Decision Manager roles. To enable LDAP role mapping, set the following parameters:

      • RoleMapping rolesProperties file path (AUTH_ROLE_MAPPER_ROLES_PROPERTIES): The fully qualified pathname of a file that defines role mapping, for example, /opt/eap/standalone/configuration/rolemapping/rolemapping.properties. You must provide this file and mount it at this path in all applicable deployment configurations; for instructions, see Section 3.3, “Providing the LDAP role mapping file”.
      • RoleMapping replaceRole property (AUTH_ROLE_MAPPER_REPLACE_ROLE): If set to true, mapped roles replace the roles defined on the LDAP server; if set to false, both mapped roles and roles defined on the LDAP server are set as user application roles. The default setting is false.

  6. Complete the creation of the environment, depending on the method that you are using:

    • In the OpenShift Web UI, click Create.

      • If the This will create resources that may have security or project behavior implications message appears, click Create Anyway.
    • Complete and run the command line.

3.2. Deploying an immutable Decision Server from KJAR services

To deploy an immutable Decision Server from KJAR services, use the rhdm73-kieserver.yaml template file. You can extract this file

from the rhdm-7.3.0-openshift-templates.zip product deliverable file. You can download the file from the Software Downloads page.

In this method of deployment, the Decision Server retrieves all the required KJAR files during the startup of the pod.

Procedure

  1. Use one of the following methods to deploy the template:

    • In the OpenShift Web UI, select Add to Project → Import YAML / JSON and then select or paste the template file. In the Add Template window, ensure Process the template is selected and click Continue.

    • To use the OpenShift command line console, prepare the following command line: 

      oc new-app -f <template-path>/<template-file-name>.yaml -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret

      In this command line:

      • Replace <template-path> with the path to the template file.
      • Replace <template-file-name> with the name of the template file.
      • Use as many -p PARAMETER=value pairs as needed to set the required parameters. You can view the template file to see descriptions for all parameters.

    • Application Name (APPLICATION_NAME): The name of the OpenShift application. It is used in the default URL for Decision Server. OpenShift uses the application name to create a separate set of deployment configurations, services, routes, labels, and artifacts. You can deploy several applications using the same template into the same project, as long as you use different application names. Also, the application name determines the name of the server configuration (server template) on the Business Central that the Decision Server is to join. If you are deploying several Decision Servers, you must ensure each of the servers has a different application name.
    • KIE Server Certificate Name (KIE_SERVER_HTTPS_NAME): The name of the certificate in the keystore that you created in Section 2.2, “Creating the secrets for Decision Server”.
    • KIE Server Keystore Password (KIE_SERVER_HTTPS_PASSWORD): The password for the keystore that you created in Section 2.2, “Creating the secrets for Decision Server”.
    • KIE Server Mode (KIE_SERVER_MODE): Set to DEVELOPMENT if you need to deploy a SNAPSHOT version of a KJAR artifact. In the rhdm73-kieserver.yaml template the default value is PRODUCTION, which does not allow deployment of SNAPSHOT versions.
    • KIE Server Container Deployment (KIE_SERVER_CONTAINER_DEPLOYMENT): The identifying information of the decision services (KJAR files) that the deployment must pull from the Maven repository. The format is: <containerId>=<groupId>:<artifactId>:<version>. You can provide two or more KJAR files using the | separator, for example: containerId=groupId:artifactId:version|c2=g2:a2:v2.
    • Maven repository URL (MAVEN_REPO_URL): The URL for the Maven repository.
    • Maven repository username (MAVEN_REPO_USERNAME): The username for the Maven repository.
    • Maven repository password (MAVEN_REPO_PASSWORD): The password for the Maven repository.

    • KIE Server Startup Strategy (KIE_SERVER_STARTUP_STRATEGY): You must set this parameter to LocalContainersStartupStrategy for an immutable deployment.
    • ImageStream Namespace (IMAGE_STREAM_NAMESPACE): The namespace where the image streams are available. If the image streams were already available in your OpenShift environment (see Section 2.1, “Ensuring the availability of image streams and the image registry”), the namespace is openshift. If you have installed the image streams file, the namespace is the name of the OpenShift project.

  3. If your OpenShift environment does not have outgoing access to the public Internet, set the following parameters:

    • Maven mirror URL (MAVEN_MIRROR_URL): The URL for the Maven mirror repository that you set up in Section 2.4, “Preparing a Maven mirror repository for offline use”. This URL must be accessible from a pod in your OpenShift environment.

For instructions about setting the mirrorOf value, see Mirror Settings in the Apache Maven documentation. The default value is external:*. With this value, Maven retrieves every required artifact from the mirror and does not query any other repositories.

      • If you configure an external Maven repository (MAVEN_REPO_URL), change MAVEN_MIRROR_OF to exclude the artifacts in this repository from the mirror, for example, external:*,!repo-custom. Replace repo-custom with the ID that you configured in MAVEN_REPO_ID.
      • If you configure a built-in Business Central Maven repository (BUSINESS_CENTRAL_MAVEN_SERVICE), change MAVEN_MIRROR_OF to exclude the artifacts in this repository from the mirror: external:*,!repo-rhdmcentr.

      • If you configure both repositories, change MAVEN_MIRROR_OF to exclude the artifacts in both repositories from the mirror: external:*,!repo-rhdmcentr,!repo-custom. Replace repo-custom with the ID that you configured in MAVEN_REPO_ID.

        +

  4. If you want to use RH-SSO or LDAP authentication, complete the following additional configuration. Do not configure LDAP authentication and RH-SSO authentication in the same deployment.

    1. In the RH-SSO or LDAP service, create all user names in the deployment parameters. If you do not set any of the parameters, create users with the default user names. The created users must also be assigned to roles:

      • KIE_ADMIN_USER: default user name adminUser, roles: kie-server,rest-all,admin
      • KIE_SERVER_USER: default user name executionUser, roles kie-server,rest-all,guest

        • KIE Server Custom http Route Hostname (KIE_SERVER_HOSTNAME_HTTP): The fully qualified host name to use for the HTTP endpoint for Decision Server. If you need to create a client in RH-SSO, you can not leave this parameter blank.
        • KIE Server Custom https Route Hostname (KIE_SERVER_HOSTNAME_HTTPS): The fully qualified host name to use for the HTTPS endpoint for Decision Server. If you need to create a client in RH-SSO, you can not leave this parameter blank.
        • RH-SSO Realm Admin Username (SSO_USERNAME) and RH-SSO Realm Admin Password (SSO_PASSWORD): The user name and password for the realm administrator user for the RH-SSO realm for Red Hat Decision Manager.
        • RH-SSO Disable SSL Certificate Validation (SSO_DISABLE_SSL_CERTIFICATE_VALIDATION): Set to true if your RH-SSO installation does not use a valid HTTPS certificate.

    3. To configure LDAP, set the AUTH_LDAP* parameters of the template. These parameters correspond to the settings of the LdapExtended Login module of Red Hat JBoss EAP. For instructions about using these settings, see LdapExtended Login Module.

      If the LDAP server does not define all the roles required for your deployment, you can map LDAP groups to Red Hat Decision Manager roles. To enable LDAP role mapping, set the following parameters:

      • RoleMapping rolesProperties file path (AUTH_ROLE_MAPPER_ROLES_PROPERTIES): The fully qualified pathname of a file that defines role mapping, for example, /opt/eap/standalone/configuration/rolemapping/rolemapping.properties. You must provide this file and mount it at this path in all applicable deployment configurations; for instructions, see Section 3.3, “Providing the LDAP role mapping file”.
      • RoleMapping replaceRole property (AUTH_ROLE_MAPPER_REPLACE_ROLE): If set to true, mapped roles replace the roles defined on the LDAP server; if set to false, both mapped roles and roles defined on the LDAP server are set as user application roles. The default setting is false.

  5. Complete the creation of the environment, depending on the method that you are using:

    • In the OpenShift Web UI, click Create.

      • If the This will create resources that may have security or project behavior implications message appears, click Create Anyway.
    • Complete and run the command line.

3.3. Providing the LDAP role mapping file

If you configure the AUTH_ROLE_MAPPER_ROLES_PROPERTIES parameter, you must provide a file that defines the role mapping. Mount this file on all affected deployment configurations.

Procedure

  1. Create the role mapping properties file, for example, my-role-map. The file must contain entries in the following format: 

    ldap_role = product_role1, product_role2...

    For example: 

    admins = kie-server,rest-all,admin

  2. Create an OpenShift configuration map from the file by entering the following command: 

    oc create configmap ldap-role-mapping --from-file=<new_name>=<existing_name>

    Replace <new_name> with the name that the file is to have on the pods (it must be the same as the name specified in the AUTH_ROLE_MAPPER_ROLES_PROPERTIES file) and <existing_name> with the name of the file that you created. For example: 

    oc create configmap ldap-role-mapping --from-file=rolemapping.properties=my-role-map

  3. Mount the configuration map on every deployment configuration that is configured for role mapping.

    The following deployment configurations can be affected in this environment:

    • myapp-kieserver: Decision Server

    Replace myapp with the application name. Sometimes, several Decision Server deployments can be present under different application names.

    For every deployment configuration, run the command: 

     oc set volume dc/<deployment_config_name> --add --type configmap --configmap-name ldap-role-mapping --mount-path=<mapping_dir> --name=ldap-role-mapping

    Replace <mapping_dir> with the directory name (without file name) set in the AUTH_ROLE_MAPPER_ROLES_PROPERTIES parameter, for example, /opt/eap/standalone/configuration/rolemapping .

AUTH_LDAP_BASE_CTX_DN

LDAP Base DN of the top-level context to begin the user search.

${AUTH_LDAP_BASE_CTX_DN}

AUTH_LDAP_BASE_FILTER

LDAP search filter used to locate the context of the user to authenticate. The input username or userDN obtained from the login module callback is substituted into the filter anywhere a {0} expression is used. A common example for the search filter is (uid={0}).

${AUTH_LDAP_BASE_FILTER}

AUTH_LDAP_SEARCH_SCOPE

The search scope to use.

${AUTH_LDAP_SEARCH_SCOPE}

AUTH_LDAP_SEARCH_TIME_LIMIT

The timeout in milliseconds for user or role searches.

${AUTH_LDAP_SEARCH_TIME_LIMIT}

AUTH_LDAP_DISTINGUISHED_NAME_ATTRIBUTE

The name of the attribute in the user entry that contains the DN of the user. This may be necessary if the DN of the user itself contains special characters, backslash for example, that prevent correct user mapping. If the attribute does not exist, the entry’s DN is used.

${AUTH_LDAP_DISTINGUISHED_NAME_ATTRIBUTE}

AUTH_LDAP_PARSE_USERNAME

A flag indicating if the DN is to be parsed for the username. If set to true, the DN is parsed for the username. If set to false the DN is not parsed for the username. This option is used together with usernameBeginString and usernameEndString.

${AUTH_LDAP_PARSE_USERNAME}

AUTH_LDAP_USERNAME_BEGIN_STRING

Defines the String which is to be removed from the start of the DN to reveal the username. This option is used together with usernameEndString and only taken into account if parseUsername is set to true.

${AUTH_LDAP_USERNAME_BEGIN_STRING}

AUTH_LDAP_USERNAME_END_STRING

Defines the String which is to be removed from the end of the DN to reveal the username. This option is used together with usernameEndString and only taken into account if parseUsername is set to true.

${AUTH_LDAP_USERNAME_END_STRING}

AUTH_LDAP_ROLE_ATTRIBUTE_ID

Name of the attribute containing the user roles.

${AUTH_LDAP_ROLE_ATTRIBUTE_ID}

AUTH_LDAP_ROLES_CTX_DN

The fixed DN of the context to search for user roles. This is not the DN where the actual roles are, but the DN where the objects containing the user roles are. For example, in a Microsoft Active Directory server, this is the DN where the user account is.

${AUTH_LDAP_ROLES_CTX_DN}

AUTH_LDAP_ROLE_FILTER

A search filter used to locate the roles associated with the authenticated user. The input username or userDN obtained from the login module callback is substituted into the filter anywhere a {0} expression is used. The authenticated userDN is substituted into the filter anywhere a {1} is used. An example search filter that matches on the input username is (member={0}). An alternative that matches on the authenticated userDN is (member={1}).

${AUTH_LDAP_ROLE_FILTER}

AUTH_LDAP_ROLE_RECURSION

The number of levels of recursion the role search will go below a matching context. Disable recursion by setting this to 0.

${AUTH_LDAP_ROLE_RECURSION}

AUTH_LDAP_DEFAULT_ROLE

A role included for all authenticated users.

${AUTH_LDAP_DEFAULT_ROLE}

AUTH_LDAP_ROLE_NAME_ATTRIBUTE_ID

Name of the attribute within the roleCtxDN context which contains the role name. If the roleAttributeIsDN property is set to true, this property is used to find the role object’s name attribute.

${AUTH_LDAP_ROLE_NAME_ATTRIBUTE_ID}

AUTH_LDAP_PARSE_ROLE_NAME_FROM_DN

A flag indicating if the DN returned by a query contains the roleNameAttributeID. If set to true, the DN is checked for the roleNameAttributeID. If set to false, the DN is not checked for the roleNameAttributeID. This flag can improve the performance of LDAP queries.

${AUTH_LDAP_PARSE_ROLE_NAME_FROM_DN}

AUTH_LDAP_ROLE_ATTRIBUTE_IS_DN

Whether or not the roleAttributeID contains the fully-qualified DN of a role object. If false, the role name is taken from the value of the roleNameAttributeId attribute of the context name. Certain directory schemas, such as Microsoft Active Directory, require this attribute to be set to true.

${AUTH_LDAP_ROLE_ATTRIBUTE_IS_DN}

AUTH_LDAP_REFERRAL_USER_ATTRIBUTE_ID_TO_CHECK

If you are not using referrals, you can ignore this option. When using referrals, this option denotes the attribute name which contains users defined for a certain role, for example member, if the role object is inside the referral. Users are checked against the content of this attribute name. If this option is not set, the check will always fail, so role objects cannot be stored in a referral tree.

${AUTH_LDAP_REFERRAL_USER_ATTRIBUTE_ID_TO_CHECK}

AUTH_ROLE_MAPPER_ROLES_PROPERTIES

When present, the RoleMapping Login Module will be configured to use the provided file. This parameter defines the fully-qualified file path and name of a properties file or resource which maps roles to replacement roles. The format is original_role=role1,role2,role3

${AUTH_ROLE_MAPPER_ROLES_PROPERTIES}

AUTH_ROLE_MAPPER_REPLACE_ROLE

Whether to add to the current roles, or replace the current roles with the mapped ones. Replaces if set to true.

4.2. OpenShift usage quick reference

To deploy, monitor, manage, and undeploy Red Hat Decision Manager templates on Red Hat OpenShift Container Platform, you can use the OpenShift Web console or the oc command.

For instructions about using the Web console, see Create and build an image using the Web console.

For detailed instructions about using the oc command, see CLI Reference. The following commands are likely to be required:

  • To create a project, use the following command: 

    $ oc new-project <project-name>

    For more information, see Creating a project using the CLI.

  • To deploy a template (create an application from a template), use the following command: 

    $ oc new-app -f <template-name> -p <parameter>=<value> -p <parameter>=<value> ...

    For more information, see Creating an application using the CLI.

  • To view a list of the active pods in the project, use the following command: 

    $ oc get pods

  • To view the current status of a pod, including information whether or not the pod deployment has completed and it is now in a running state, use the following command: 

    $ oc describe pod <pod-name>

    You can also use the oc describe command to view the current status of other objects. For more information, see Application modification operations.

  • To view the logs for a pod, use the following command: 

    $ oc logs <pod-name>

  • To view deployment logs, look up a DeploymentConfig name in the template reference and run the following command: 

    $ oc logs -f dc/<deployment-config-name>

    For more information, see Viewing deployment logs.

  • To view build logs, look up a BuildConfig name in the template reference and run the command: 

    $ oc logs -f bc/<build-config-name>

    For more information, see Accessing build logs.

  • To scale a pod in the application, look up a DeploymentConfig name in the template reference and run the command: 

    $ oc scale dc/<deployment-config-name> --replicas=<number>

    For more information, see Manual scaling.

  • To undeploy the application, you can delete the project by using the command: 

    $ oc delete project <project-name>

    Alternatively, you can use the oc delete command to remove any part of the application, such as a pod or replication controller. For details, see Application modification operations.
