Installing Decision Optimization

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

Prerequisites

Required role: To complete this task, you must be an administrator of the project (namespace) where you will deploy Decision Optimization.

Before you install Decision Optimization, ensure that:

If you are installing multiple services on your cluster, you must run the installations one at a time and wait until the installation completes before installing another service. You cannot run the installations in parallel.

Tip: For a list of all available options, enter the following command:
./cpd-cli install --help
Important: For Decision Optimization installation, you must have both Watson Machine Learning and Watson Studio already installed.

Procedure

  1. Complete the appropriate steps to install Decision Optimization on your environment:
  2. Verifying that the installation completed successfully
  3. Checking for available patches
  4. Complete the tasks listed in What to do next

Installing on clusters connected to the internet

From your installation node:

  1. Change to the directory where you placed the Cloud Pak for Data command-line interface and the repo.yaml file.
  2. Log in to your Red Hat OpenShift cluster as a project administrator:
    oc login OpenShift_URL:port
  3. Run the following command to see a preview of what will be installed when you install the service.
    Important: If you are using the internal Red Hat OpenShift registry and you are using the default self-signed certificate, specify the --insecure-skip-tls-verify flag to prevent x509 errors.
    ./cpd-cli install \
    --repo ./repo.yaml \
    --assembly dods \
    --arch Cluster_architecture \
    --namespace Project \
    --storageclass Storage_class_name \
    --transfer-image-to Registry_location \
    --cluster-pull-prefix Registry_from_cluster \
    --ask-push-registry-credentials \
    --latest-dependency \
    --dry-run
    Important: By default, this command gets the latest version of the assembly. If you want to install a specific version of Decision Optimization, add the following line to your command after the --assembly flag:
    --version Assembly_version \

    The --latest-dependency flag gets the latest version of the dependent assemblies. If you remove the --latest-dependency flag, the installer will get the minimum version of the dependent assemblies.

    If you are installing with Portworx storage, add the following line to your installation command after the --storageclass flag:
    --override-config portworx \
    If you are installing with OpenShift Container Storage, add the following line to your installation command after the --storageclass flag:
    --override-config ocs \

    Replace the following values:

    Variable Replace with
    Assembly_version
    The version of Decision Optimization that you want to install. The assembly versions are listed in System requirements for services.
    Cluster_architecture Specify the architecture of your cluster hardware:
    • For x86-64 hardware, remove this flag or specify x86_64
    • For POWER hardware, specify ppc64le
    Project Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Storage_class_name Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Registry_location Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Registry_from_cluster Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
  4. Rerun the previous command without the --dry-run flag to install the service.

Installing on air-gapped clusters

From your installation node:

  1. Download the required files and then transfer the files to a machine that is accessible from the cluster, see Preparing for air-gapped installations.
  2. Change to the directory where you placed the Cloud Pak for Data command-line interface.
  3. Log in to your Red Hat OpenShift cluster as a project administrator:
    oc login OpenShift_URL:port
  4. Run the following command to see a preview of what will be installed when you install the service.
    Important: If you are using the internal Red Hat OpenShift registry:
    • Do not specify the --ask-pull-registry-credentials parameter.
    • If you are using the default self-signed certificate, specify the --insecure-skip-tls-verify flag to prevent x509 errors.
    ./cpd-cli install \
    --assembly dods \
    --arch Cluster_architecture \
    --namespace Project \
    --storageclass Storage_class_name \
    --cluster-pull-prefix Registry_from_cluster \
    --ask-pull-registry-credentials \
    --load-from Image_directory_location \
    --latest-dependency \
    --dry-run
    Note: If the assembly was downloaded using the delta-images command, remove the --latest-dependency flag from the command. If you don't remove the --latest-dependency flag you will get an error indicating that the flag cannot be used.
    If you are installing with Portworx storage, add the following line to your installation command after the --storageclass flag:
    --override-config portworx \
    If you are installing with OpenShift Container Storage, add the following line to your installation command after the --storageclass flag:
    --override-config ocs \

    Replace the following values:

    Variable Replace with
    Cluster_architecture Specify the architecture of your cluster hardware:
    • For x86-64 hardware, remove this flag or specify x86_64
    • For POWER hardware, specify ppc64le
    Project Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Storage_class_name Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Registry_from_cluster Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.
    Image_directory_location The location of the cpd-cli-workspace directory.

    Use the value provided by your cluster administrator. You should have obtained this information when you completed Preparing to install and upgrade services.

  5. Rerun the previous command without the --dry-run flag to install the service.

Verifying that the installation completed successfully

From your installation node:

  1. Run the following command:
    ./cpd-cli status \
    --assembly dods \
    --namespace Project

    Replace Project with the value you used in when you installed Decision Optimization.

    • If the installation completed successfully, the status of the assembly and the modules in the assembly is Ready.
    • If the installation failed, contact IBM Support for assistance.

Checking for available patches

Determine whether there are any patches available for the version of Decision Optimization that you installed:

Clusters connected to the internet
Run the following command to check for patches:
./cpd-cli status \
--repo ./repo.yaml \
--namespace Project \ 
--assembly dods \
--patches \
--available-updates 
Air-gapped clusters
See the list of Available patches for Decision Optimization.

If you need to apply patches to the service, follow the guidance in Applying patches.

What to do next

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