Installing Decision Optimization

An instance administrator can install Decision Optimization on IBM® Software Hub Version 5.4.

Who needs to complete this task?

Instance administrator To install Decision Optimization, you must be an instance administrator. An instance administrator has permission to install software in the following projects:

The operators project for the instance

The operators for this instance of Decision Optimization are installed in the operators project.

In the installation commands, the ${PROJECT_CPD_INST_OPERATORS} environment variable refers to the operators project.

The operands project for the instance

The custom resources for the control plane and Decision Optimization are installed in the operands project.

In the installation commands, the ${PROJECT_CPD_INST_OPERANDS} environment variable refers to the operands project.

When do you need to complete this task?

Review the following options to determine whether you need to complete this task:

If you want to install multiple services at the same time, follow the process in Running a batch installation of solutions and services instead.
If you didn't install Decision Optimization as part of a batch installation, complete this task to add Decision Optimization to your environment.
Repeat as needed If you are responsible for multiple instances of IBM Software Hub, you can repeat this task to install more instances of Decision Optimization on the cluster.

Information you need to complete this task

Review the following information before you install Decision Optimization:

Version requirements: All of the components that are associated with an instance of IBM Software Hub must be installed at the same release. For example, if the IBM Software Hub control plane is installed at Version 5.4.0, you must install Decision Optimization at Version 5.4.0.

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, run:
```
source ./cpd_vars.sh
```

Security context constraint: Decision Optimization works with the default Red Hat® OpenShift® Container Platform security context constraint, restricted-v2.

Common core services

Decision Optimization requires the IBM Software Hub common core services.

If the common core services are not installed in the operands project for the instance, the common core services are automatically installed when you install Decision Optimization. The common core services installation increases the amount of time the installation takes to complete.

Storage requirements: You don't need to specify storage information when you install Decision Optimization.

Before you begin

This task assumes that the following prerequisites are met:

System requirements

This task assumes that the cluster meets the minimum requirements for Decision Optimization.

Where to find more information
If this task is not complete, see System requirements.

Workstation

This task assumes that the workstation from which you will run the installation is set up as a client workstation and has the following command-line interfaces:

IBM Software Hub CLI: cpd-cli
OpenShift CLI: oc
Helm CLI: helm

Where to find more information
If this task is not complete, see Setting up a client workstation.

Control plane

This task assumes that the IBM Software Hub control plane is installed.

Where to find more information
If this task is not complete, see Installing an instance of IBM Software Hub.

Private container registry

If your environment uses a private container registry (for example, your cluster is air-gapped), this task assumes that the following tasks are complete:

The Decision Optimization software images are mirrored to the private container registry.
Where to find more information

If this task is not complete, see Mirroring images to a private container registry.
The cpd-cli is configured to pull the olm-utils-v4 image from the private container registry.

If this task is not complete, see Pulling the olm-utils-v4 image from the private container registry.

Cluster-scoped resources

Where to find more information
If this task is not complete, see Mirroring images to a private container registry.

Where to find more information
If this task is not complete, see Pulling the olm-utils-v4 image from the private container registry.

This task assumes that the cluster-scoped resources, such as custom resource definitions, cluster roles, and cluster role bindings, exist.

Where to find more information
If this task is not complete, see Creating cluster-scoped resources for the IBM Software Hub platform and services.

Image pull secrets

This task assumes that the secrets that contain the image pull credentials for the instance exist.

Where to find more information
If this task is not complete, see Creating image pull secrets for an instance of IBM Software Hub.

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:

Installing the service
Validating the installation
What to do next

Installing the service

To install Decision Optimization:

Log the cpd-cli in to the Red Hat OpenShift Container Platform cluster:
```
${CPDM_OC_LOGIN}
```
Remember: CPDM_OC_LOGIN is an alias for the cpd-cli manage login-to-ocp command.

Install the operator and custom resource for Decision Optimization.

cpd-cli manage install-components \
--license_acceptance=true \
--components=dods \
--release=${VERSION} \
--patch_id=${PATCH_ID} \
--operator_ns=${PROJECT_CPD_INST_OPERATORS} \
--instance_ns=${PROJECT_CPD_INST_OPERANDS} \
--image_pull_prefix=${IMAGE_PULL_PREFIX} \
--image_pull_secret=${IMAGE_PULL_SECRET}

Validating the installation

Decision Optimization is installed when the install-components command returns:

[SUCCESS]... The install-components command ran successfully

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

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

What to do next

Decision Optimization is ready to use.

Optional: Set the scaling for the service.
