Installing Decision Optimization

A project administrator can install Decision Optimization on IBM Cloud Pak® for Data.

What permissions do you need to complete this task?
The permissions that you need depend on which tasks you must complete:
  • To install the Decision Optimization operators, you must have the appropriate permissions to create operators and you must be an administrator of the project where the Cloud Pak for Data operators are installed. This project is identified by the ${PROJECT_CPD_OPS} environment variable.
  • To install Decision Optimization, you must be an administrator of the project where you will install Decision Optimization. This project is identified by the ${PROJECT_CPD_INSTANCE} environment variable.

Information you need to complete this task

Review the following information before you install Decision Optimization:

Environment variables
The commands in this task use environment variables so that you can run the commands exactly as written.
  • If you don't have the script that defines the environment variables, see Setting up installation environment variables.
  • To use the environment variables from the script, you must source the environment variables before you run the commands in this task, for example:
    source ./cpd_vars.sh
Security context constraint requirements
Decision Optimization uses the restricted security context constraint (SCC).
Installation location
Decision Optimization must be installed in the same project (namespace) as the Cloud Pak for Data control plane. This project is identified by the ${PROJECT_CPD_INSTANCE} environment variable.
Storage requirements
You don't need to specify storage when you install Decision Optimization.

Before you begin

This task assumes that the following prerequisites are met:

Prerequisite Where to find more information
The cluster meets the minimum requirements for installing Decision Optimization. If this task is not complete, see System requirements.
The workstation from which you will run the installation is set up as a client workstation and includes the following command-line interfaces:
  • Cloud Pak for Data CLI: cpd-cli
  • OpenShift® CLI: oc
 If this task is not complete, see Setting up a client workstation.
The Cloud Pak for Data control plane is installed. If this task is not complete, see Installing the platform and services.
For environments that use a private container registry, such as air-gapped environments, the Decision Optimization software images are mirrored to the private container registry. If this task is not complete, see Mirroring images to a private container registry.

Prerequisite services

Before you install Decision Optimization, ensure that the following services are installed and running:

Procedure

Complete the following tasks to install Decision Optimization:

  1. Logging in to the cluster
  2. Installing the operator
  3. Installing the service
  4. Validating the installation
  5. What to do next

Logging in to the cluster

To run cpd-cli manage commands, you must log in to the cluster.

To log in to the cluster:

  1. Run the cpd-cli manage login-to-ocp command to log in to the cluster as a user with sufficient permissions to complete this task. For example:
    cpd-cli manage login-to-ocp \
--username=${OCP_USERNAME} \
--password=${OCP_PASSWORD} \
--server=${OCP_URL}
    Tip: The login-to-ocp command takes the same input as the oc login command. Run oc login --help for details.

Installing the operator

The Decision Optimization operator simplifies the process of managing the Decision Optimization service on Red Hat® OpenShift Container Platform.

To install Decision Optimization, you must install the Decision Optimization operator and create the Operator Lifecycle Manager (OLM) objects, such as the catalog source and subscription, for the operator.

Who needs to complete this task?
You must be a cluster administrator (or a user with the appropriate permissions to install operators) to create the OLM objects.
When do you need to complete this task?
Complete this task if the Decision Optimization operator and other OLM artifacts have not been created for the current release.

If you complete this task and the OLM artifacts already exist on the cluster, the cpd-cli detects that you already have the OLM objects for the components at the specified release, the cpd-cli does not attempt to create the OLM objects again.

To install the operator:

  1. Create the OLM objects for Decision Optimization:
    cpd-cli manage apply-olm \
--release=${VERSION} \
--cpd_operator_ns=${PROJECT_CPD_OPS} \
--components=dods
    • If the command succeeds, it returns [SUCCESS]... The apply-olm command ran successfully.
    • If the command fails, it returns [ERROR] and includes information about the cause of the failure.

What to do next: Install the Decision Optimization service.

Installing the service

After the Decision Optimization operator is installed, you can install Decision Optimization.

Who needs to complete this task?
You must be an administrator of the project where you will install Decision Optimization.
When do you need to complete this task?
Complete this task if you want to add Decision Optimization to your environment.

To install the service:

  1. Create the custom resource for Decision Optimization.
    cpd-cli manage apply-cr \
--components=dods \
--release=${VERSION} \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--license_acceptance=true

Validating the installation

Decision Optimization is installed when the apply-cr command returns [SUCCESS]... The apply-cr command ran successfully.

However, you can optionally run the cpd-cli manage get-cr-status command if you want to confirm that the custom resource status is Completed:

cpd-cli manage get-cr-status \
--cpd_instance_ns=${PROJECT_CPD_INSTANCE} \
--components=dods

What to do next

Optional: Set the scaling for the service.

The service is ready to use. For details, see Building Decision Optimization models.
