Chapter 3. Authoring environment

You can deploy an environment for creating and modifying processes using Business Central. It consists of Business Central for the authoring work and Process Server for test execution of the processes.

Depending on your needs, you can deploy either a single authoring environment or a high-availability (HA) authoring environment.

A single authoring environment contains two pods. One of the pods runs Business Central, the other runs Process Server. The Process Server includes an embedded in-memory H2 database engine. This type of environment uses the least possible amount of resources. However, because of the in-memory database, restarting the Process Server pod leads to loss of all process information.

An HA authoring environment contains several pods. Both Business Central and Process Server are provided in scalable pods that can run in parallel and share persistent storage. The database is provided by a separate high-availability service. Use a high-availability authoring environment to provide maximum reliability and responsiveness, especially if several users are involved in authoring at the same time.

Important

In the current version, the high-availability functionality is a technology preview.

3.1. Deploying a single authoring environment
Link kopieren

To deploy a single authoring environment, use the rhpam72-authoring.yaml template file.

You can extract this file from the rhpam-7.2.0-openshift-templates.zip product deliverable file. You can download the file from the Software Downloads page.

If you want to modify the environment defined by the template file, see Section 3.5, “Modifying the template for the single authoring environment”.

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 rhpam72-authoring.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>/rhpam72-authoring.yaml -p BUSINESS_CENTRAL_HTTPS_SECRET=businesscentral-app-secret -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:

    • Business Central Server Keystore Secret Name (BUSINESS_CENTRAL_HTTPS_SECRET): The name of the secret for Business Central, as created in Section 2.3, “Creating the secrets for Business Central”.

    • Application Name (APPLICATION_NAME): The name of the OpenShift application. It is used in the default URLs for Business Central and Process 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 Process Server is to join.
    • Business Central Server Certificate Name (BUSINESS_CENTRAL_HTTPS_NAME): The name of the certificate in the keystore that you created in Section 2.3, “Creating the secrets for Business Central”.

If you configure the GIT_HOOKS_DIR parameter, you must provide a directory of Git hooks and must mount this directory on the Business Central deployment.

The typical use of Git hooks is interaction with an upstream repository. To enable Git hooks to push commits into an upstream repository, you must also provide a secret key that corresponds to a public key configured on the upstream repository.

Procedure

  1. If interaction with an upstream repository using SSH authentication is required, complete the following steps to prepare and mount a secret with the necessary files:

    1. Prepare the id_rsa file with a private key that matches a public key stored in the repository.
    2. Prepare the known_hosts file with the correct name, address, and public key for the repository.

    3. Create a secret with the two files using the oc command, for example: 

      oc create secret git-hooks-secret --from-file=id_rsa=id_rsa --from-file=known_hosts=known_hosts

    4. Mount the secret in the SSH key path of the Business Central deployment, for example: 

      oc set volume dc/<myapp>-rhpamcentr --add --type secret --secret-name git-hooks-secret --mount-path=/home/jboss/.ssh --name=ssh-key

      Where <myapp> is the application name that was set when configuring the template.

  2. Create the Git hooks directory. For instructions, see the Git hooks reference documentation.

    For example, a simple git hooks directory can provide a post-commit hook that pushes the changes upstream. If the project was imported into Business Central from a repository, this repository remains configured as the upstream repository. Create a file named post-commit with permission values 755 and the following content: 

    git push

  3. Supply the Git hooks directory to the Business Central deployment. You can use a configuration map or a persistent volume.

    1. If the Git hooks consist of one or several fixed script files, use a configuration map. Complete the following steps:

      1. Change into the Git hooks directory that you have created.

      2. Create an OpenShift configuration map from the files in the directory. Run the following command: 

        oc create configmap git-hooks --from-file=<file_1>=<file_1> --from-file=<file_2>=<file_2> ...

        Where file_1, file_2 and so on are git hook script files. For example: 

        oc create configmap git-hooks --from-file=post-commit=post-commit

      3. Mount the configuration map on the Business Central deployment in the path that you have configured: 

        oc set volume dc/<myapp>-rhpamcentr --add --type configmap --configmap-name git-hooks  --mount-path=<git_hooks_dir> --name=git-hooks

        Where <myapp> is the application name that was set when configuring the template and <git_hooks_dir> is the value of GIT_HOOKS_DIR that was set when configuring the template.

    2. If the Git hooks consist of long files or depend on binaries, such as executable or KJAR files, use a persistence volume. You must create a persistent volume, create a persistent volume claim and associate the volume with the claim, transfer files to the volume, and mount the volume in the myapp-rhpamcentr deployment configuration (where myapp is the application name). For instructions about creating and mounting persistence volumes, see Using persistent volumes. For instructions about copying files onto a persistent volume, see Transferring files in and out of containers.

  4. Wait a few minutes, then review the list and status of pods in yor project. Because Business Central does not start until you provide the Git hooks directory, the Process Server might not start at all. To see if it has started, check the output of the following command: 

    oc get pods

    If a working Process Server pod is not present, start it: 

    oc rollout latest dc/<myapp>-kieserver

    Where <myapp> is the application name that was set when configuring the template.

3.5. Modifying the template for the single authoring environment
Link kopieren

By default, the single authoring template uses the H2 database with permanent storage. If you prefer to create a MySQL or PostgreSQL pod or to use an external database server (outside the OpenShift project), you need to modify the template before deploying the environment.

An OpenShift template defines a set of objects that can be created by OpenShift. To change an environment configuration, you need to modify, add, or delete these objects. To simplify this task, comments are provided in the Red Hat Process Automation Manager templates.

Some comments mark blocks within the template, staring with BEGIN and ending with END. For example, the following block is named Sample block: 

## Sample block BEGIN
sample line 1
sample line 2
sample line 3
## Sample block END

For some changes, you might need to replace a block in one template file with a block from another template file provided with Red Hat Process Automation Manager. In this case, delete the block, then paste the new block in its exact location.

Procedure

Edit the rhpam72-authoring.yaml template file to make any of the following changes as necessary.

  • If you want to use MySQL instead of the H2 database, you need to replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam72-kieserver-mysql.yaml file that are also marked with comments. You also need to remove several other blocks and to add blocks in designated locations:

    1. Replace the block named H2 database parameters with the block named MySQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam72-kieserver-mysql.yaml file.)
    2. Replace the block named H2 driver settings with the block named MySQL driver settings
    3. Replace the block named H2 persistent volume claim with the block named MySQL persistent volume claim.
    4. Remove the blocks named H2 volume mount and H2 volume settings
    5. Under the comment Place to add database service, add the block named MySQL service
    6. Under the comment Place to add database deployment config, add the block named MySQL deployment config

  • If you want to use PostgreSQL instead of the H2 database, you need to replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam72-kieserver-postgresql.yaml file that are also marked with comments. You also need to remove several other blocks and to add blocks in designated locations:

    1. Replace the block named H2 database parameters with the block named PostgreSQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam72-kieserver-postgresql.yaml file.)
    2. Replace the block named H2 driver settings with the block named PostgreSQL driver settings
    3. Replace the block named H2 persistent volume claim with the block named PostgreSQL persistent volume claim.
    4. Remove the blocks named H2 volume mount and H2 volume settings
    5. Under the comment Place to add database service, add the block named PostgreSQL service
    6. Under the comment Place to add database deployment config, add the block named PostgreSQL deployment config

  • If you want to use an external database server, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam72-kieserver-externaldb.yaml file, and also remove some blocks:

    1. Replace the block named H2 database parameters with the block named External database parameters. (Take this block and all subsequent replacement blocks from the rhpam72-kieserver-externaldb.yaml file.)
    2. Replace the block named H2 driver settings with the block named External database driver settings.

    3. Remove the following blocks of the file, marked with comments from BEGIN to END:

      • H2 persistent volume claim
      • H2 volume mount
      • H2 volume settings

The standard Process Server image includes drivers for MySQL and PostgreSQL external database servers. If you want to use another database server, you must build a custom Process Server image. For instructions, see Section 3.7, “Building a custom Process Server image for an external database”.

By default, the high-availability authoring template creates a MySQL pod to provide the database server for the Process Server. If you prefer to use PostgreSQL or to use an external server (outside the OpenShift project), you need to modify the template before deploying the environment.

You can also modify the High Availability authoring template to change the number of replicas initially created for Business Central.

An OpenShift template defines a set of objects that can be created by OpenShift. To change an environment configuration, you need to modify, add, or delete these objects. To simplify this task, comments are provided in the Red Hat Process Automation Manager templates.

Some comments mark blocks within the template, staring with BEGIN and ending with END. For example, the following block is named Sample block: 

## Sample block BEGIN
sample line 1
sample line 2
sample line 3
## Sample block END

For some changes, you might need to replace a block in one template file with a block from another template file provided with Red Hat Process Automation Manager. In this case, delete the block, then paste the new block in its exact location.

Procedure

Edit the rhpam72-authoring-ha.yaml template file to make any of the following changes as necessary.

  • If you want to use PostgreSQL instead of MySQL, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam72-kieserver-postgresql.yaml file:

    1. Replace the block named MySQL database parameters with the block named PosgreSQL database parameters. (Take this block and all subsequent replacement blocks from the rhpam72-kieserver-postgresql.yaml file.)
    2. Replace the block named MySQL service with the block named PosgrreSQL service.
    3. Replace the block named MySQL driver settings with the block named PosgreSQL driver settings.
    4. Replace the block named MySQL deployment config with the block named PosgreSQL deployment config.
    5. Replace the block named MySQL persistent volume claim with the block named PosgreSQL persistent volume claim.

  • If you want to use an external database server, replace several blocks of the file, marked with comments from BEGIN to END, with blocks from the rhpam72-kieserver-externaldb.yaml file, and also remove some blocks:

    1. Replace the block named MySQL database parameters with the block named External database parameters. (Take this block and all subsequent replacement blocks from the rhpam72-kieserver-externaldb.yaml file.)
    2. Replace the block named MySQL driver settings with the block named External database driver settings.

    3. Remove the following blocks of the file, marked with comments from BEGIN to END:

      • MySQL service
      • MySQL deployment config
      • MySQL persistent volume claim

  • If you want to change the number of replicas initially created for Business Central, on the line below the comment ## Replicas for Business Central, change the number of replicas to the desired value.

3.7. Building a custom Process Server image for an external database
Link kopieren

If you want to use an external database server for a Process Server and this server is neither MySQL nor PostgreSQL, you must build a custom Process Server image with drivers for this server before deploying your environment.

You can use this build procedure to provide drivers for the following database servers:

  • Microsoft SQL Server
  • MariaDB
  • IBM DB2
  • Oracle Database
  • Sybase

For the tested versions of the database servers, see Red Hat Process Automation Manager 7 Supported Configurations.

The build procedure creates a custom image that extends the existing Process Server image. It pushes this custom image into a new ImageStream in the openshift namespace with the same version tag as the original image.

Prerequisites

  • You have logged on to your project in the OpenShift environment using the oc command as a user with the cluster-admin role.
  • For IBM DB2, Oracle Database, or Sybase, you have downloaded the JDBC driver from the database server vendor.

Procedure

  1. For IBM DB2, Oracle Database, or Sybase, provide the JDBC driver JAR in a local directory or on an HTTP server. Within the local directory or HTTP server, the following paths are expected:

    • For IBM DB2, <local_path_or_url>/com/ibm/db2/jcc/db2jcc4/10.5/db2jcc4-10.5.jar
    • For Oracle Database, <local_path_or_url>/com/oracle/ojdbc7/12.1.0.1/ojdbc7-12.1.0.1.jar

    • For Sybase, <local_path_or_url>/com/sysbase/jconn4/16.0_PL05/jconn4-16.0_PL05.jar

      Where <local_path_or_url> is the path to the local directory or the URL for the HTTP server where the driver is provided.

  2. To install the source code for the custom build, download the rhpam-7.2.0-openshift-templates.zip product deliverable file from the Software Downloads page. Unzip the file and, using the command line, change to the templates/contrib/jdbc directory of the unzipped file.

  3. Change to the following subdirectory:

    • For Microsoft SQL Server, mssql-driver-image
    • For MariaDB, mariadb-driver-image
    • For IBM DB2, db2-driver-image
    • For Oracle Database, oracle-driver-image
    • For Sybase, sybase-driver-image

  4. Run the following command:

    • For Microsoft SQL Server or MariaDB: 
    ../build.sh
    • For IBM DB2, Oracle Database, or Sybase: 
    ../build.sh --artifact-repo=<local_path_or_url>

    Where <local_path_or_url> is the path to the local directory or the URL for the HTTP server where the driver is provided. For example: 

    ../build.sh --artifact-repo=/home/builder/drivers
../build.sh --artifact-repo=http://nexus.example.com/nexus/content/groups/public

    If you want to configure your OpenShift docker registry address in the process, add also the --registry=<registry_name.domain_name:port> parameter to your build command.

    Examples: 

    ../build.sh --registry=docker-registry.custom-domain:80

../build.sh --artifact-repo=/home/builder/drivers --registry=docker-registry.custom-domain:80
