This tutorial explains how to start an IBM Operational Decision Manager unclustered docker topology for development, using Docker Compose.

Flow

Setting up your environment

Before you proceed, install Docker and Docker Compose.

Install Operational Decision Manager

To create Operational Decision Manager docker images, install one of the following components:

  • Decision Center, with the WebSphere Liberty Profile option,
  • Decision Server Rules, with the WebSphere Liberty Profile option.

Go to the Operational Decision Manager installation directory and locate the required WAR files in the directories listed below:

installation_directory/executionserver/applicationservers/WLP*/res.war

installation_directory/executionserver/applicationservers/WLP*/DecisionService.war

installation_directory/teamserver/applicationservers/WLP*/teamserver.war

installation_directory/teamserver/applicationservers/WLP*/decisioncenter.war

installation_directory/teamserver/applicationservers/WLP*/decisionmodel.war (starting from ODM vnext)

installation_directory/executionserver/applicationservers/WLP*/DecisionRunner.war

Clone the odm-ondocker code

In the installation directory, enter git clone https://github.com/ODMDev/odm-ondocker.git.

Copy .dockerignore file

Copy the odm-ondocker/resources/.dockerignore file into the ODM installation directory.

cp odm-ondocker/resources/.dockerignore ./

When the copy is complete, the content of your repository should be similar to this:

Flow

Verify that Docker Engine and Docker Compose are running.

Open a command prompt and run the following two commands:

  > docker -–version
  Docker version 1.12.3
  > docker-compose version
  docker-compose version 1.8.1

Now you are ready to build and run the docker images.

Build and run the docker image

Open a command prompt in the directory installation_directory/odm-ondocker and run the following command:

docker-compose  up

Note: If you have trouble on Windows os see this issue

This command builds, creates, and runs five docker containers:

  • Derby Network database server
  • ODM Decision Server runtime
  • ODM Decision Server console
  • ODM Decision Center
  • ODM Decision Runner

Docker Compose builds and runs the containers if they are not already built.

You can also choose to start only one Operational Decision Manager component. For example, this command line starts Decision Center and its dependencies, including the dbserver Derby Network server.

docker-compose up odm-decisioncenter

You can access the application with this URLs:

Component URL Username Password
Decision Server Console http://localhost:9080/res resAdmin resAdmin
Decision Server Runtime http://localhost:9090/DecisionService N/A N/A
Decision Center Business Console http://localhost:9060/decisioncenter rtsAdmin rtsAdmin
Decision Center Enterprise Console http://localhost:9060/teamserver rtsAdmin rtsAdmin
Decision Runner http://localhost:9070/DecisionRunner resDeployer resDeployer

Verifying the docker images

You can check the container status with the following command:

 docker-compose ps

This screen capture displays the list of running containers.

Flow

DBDump Usage

For support and debugging purposes, the Decision Center container is embedding DBDump in the same liberty configuration. So, the authentication access is sharing the same registry. You can access it with a user having the rtsAdministrators role as for example ODMAdmin user.

If http://<host>:<port>/decisioncenter is the URL to access the Decision Center service, you can access DBDump at the following URL : http://<host>:<port>/decisioncenter-dbdump

DBDump usage is following the same usage than explained at https://www.ibm.com/support/pages/decision-center-database-export-utility
