Chapter 11. Freeform managed server environment

download PDF

You can deploy a freeform server environment that includes several different pods running KIE Server. These KIE Servers can run different services for staging or production purposes. You can add and remove servers as necessary at any time.

You start deploying a freeform managed server environment by deploying Business Central Monitoring and one managed KIE Server. You can use Business Central Monitoring to monitor and, when necessary, manage the execution of services on KIE Servers. This environment does not include Smart Router.

You can also deploy additional managed KIE Servers. Each KIE Server can be separately scaled as necessary.

On a managed KIE Server, no services are initially loaded. Use Business Central Monitoring or the REST API of the KIE Server to deploy and undeploy processes on the server.

You must provide a Maven repository with the processes (KJAR files) that you want to deploy on the servers. Your integration process must ensure that the required versions of the processes are uploaded to the Maven repository. You can use Business Central in a development environment to create the processes and upload them to the Maven repository.

Each KIE Server uses a database server. Usually, the database servers also run in pods, although you can set up a KIE Server to use an external database server.

You can also deploy immutable KIE Servers in the same namespace. You can use Business Central Monitoring to view monitoring information for all KIE Servers in the environment, including immutable servers. For instructions about deploying immutable KIE Servers, see Section 10.2, “Deploying an immutable KIE Server using an S2I build” and Section 10.4, “Deploying an immutable KIE Server from KJAR services”..

11.1. Deploying monitoring and a single KIE Server for a freeform environment

To start deploying a freeform environment, deploy Business Central Monitoring and a single managed KIE Server, which uses a PostgreSQL database server in a pod. No services are loaded on the KIE Server. Use Business Central Monitoring to deploy and undeploy services on the server.

You can then add more KIE Servers as necessary.

11.1.1. Starting configuration of the template for monitoring and a single KIE Server

To deploy Business Central Monitoring and a single managed KIE Server, use the rhpam711-managed.yaml template file.

Procedure

  1. Download the rhpam-7.11.0-openshift-templates.zip product deliverable file from the Software Downloads page of the Red Hat Customer Portal.
  2. Extract the rhpam711-managed.yaml template file.

  3. Use one of the following methods to start deploying the template:

    • To use the OpenShift Web UI, in the OpenShift application console select Add to Project Import YAML / JSON and then select or paste the rhpam711-managed.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>/rhpam711-managed.yaml -p BUSINESS_CENTRAL_HTTPS_SECRET=businesscentral-app-secret -p KIE_SERVER_HTTPS_SECRET=kieserver-app-secret -p PARAMETER=value

      In this command line, make the following changes:

      • 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.
