Abstract

This document describes how to deploy a Red Hat Decision Manager 7.2 trial environment on Red Hat OpenShift Container Platform.

Preface

As a system engineer, you can deploy a Red Hat Decision Manager trial environment on Red Hat OpenShift Container Platform to evaluate or demonstrate development and use of rules and other business assets.

Prerequisites

  • At least three 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.

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

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

    Decision 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, Decision 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 Decision Central functionality is a technology preview.

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 Decision Central and also for running services on Decision Servers. It consists of pods that provide Decision 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 Decision 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 Decision 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. Ensuring the availability of image streams and the image registry

To deploy Red Hat Decision Manager components of 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 was 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 was configured with the user name and password for Red Hat registry access, run the following commands:

    $ oc get imagestreamtag -n openshift | grep rhdm72-decisioncentral-openshift
    $ oc get imagestreamtag -n openshift | grep rhdm72-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 was 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 on 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-7.2.0-openshift-templates.zip product deliverable file from the Software Downloads page and extract the rhdm72-image-streams.yaml file.
    7. Complete one of the following actions:

      • Run the following command:

        $ oc create -f rhdm72-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.

Chapter 3. Deploying a trial environment

You can deploy a trial (evaluation) Red Hat Decision Manager environment. It consists of Decision Central for authoring or managing services and Decision Server for test execution of services.

This environment does not include permanent storage. Assets that you create or modify in a trial environment are not saved.

This environment is intended for test and demonstration access. It supports cross-origin resource sharing (CORS). This means that Decision Server endpoints can be accessed using a browser when other resources on the page are provided by other servers. Decision Server endpoints are normally intended for REST calls, but browser access can be needed in some demonstration configurations.

The procedure is minimal. There are no required settings and all passwords are set to a single value (the default password is RedHat).

To deploy a trial environment, use the rhdm72-trial-ephemeral.yaml template file. You can extract this file from the rhdm-7.2.0-openshift-templates.zip product deliverable file. You can download the file from the Software Downloads page of the Red Hat Customer Portal.

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 rhdm72-trial-ephemeral.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>/rhdm72-trial-ephemeral.yaml

      In this command line, replace <template-path> with the path to the downloaded template file.

  2. Optionally, set any parameters as described in the template. A typical trial deployment requires only the following parameter:

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

    • In the OpenShift Web UI, click Create.

      • A This will create resources that may have security or project behavior implications pop-up message might be displayed. If it is displayed, click Create Anyway.
    • Complete and run the command line.

Chapter 4. OpenShift template reference information

Red Hat Decision Manager provides the following OpenShift templates. To access the templates, download and extract the rhdm-7.2.0-openshift-templates.zip product deliverable file from the Software Downloads page of the Red Hat customer portal.

  • rhdm72-trial-ephemeral.yaml provides a Decision Central and a Decision Server connected to the Decision Central. This environment uses an ephemeral configuration without any persistent storage. For details about this template, see Section 4.1, “rhdm72-trial-ephemeral.yaml template”.

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_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 property 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}

4.1.2.4. External Dependencies
4.1.2.4.1. Secrets

This template requires the following secrets to be installed for the application to run.

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.
