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:
- Both Watson™ Machine Learning and Watson Studio are already installed.
- The Cloud Pak for Data control plane is already installed on your Red Hat® OpenShift® cluster. For details, see Installing IBM Cloud Pak for Data.
- The cluster meets the minimum requirements for installing Decision Optimization. For details, see System requirements for services.
- You completed the steps in Preparing to install and upgrade services.
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.
./cpd-cli install --help
Procedure
- Complete the appropriate steps to install Decision Optimization on your environment:
- Verifying that the installation completed successfully
- Checking for available patches
- Complete the tasks listed in What to do next
Installing on clusters connected to the internet
From your installation node:
- Change to the directory where you placed the Cloud Pak for Data command-line interface and the repo.yaml file.
- Log in to your Red Hat OpenShift cluster as a project
administrator:
oc login OpenShift_URL:port
- 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. - Rerun the previous command without the
--dry-run
flag to install the service.
Installing on air-gapped clusters
From your installation node:
- Download the required files and then transfer the files to a machine that is accessible from the cluster, see Preparing for air-gapped installations.
- Change to the directory where you placed the Cloud Pak for Data command-line interface.
- Log in to your Red Hat OpenShift cluster as a project
administrator:
oc login OpenShift_URL:port
- 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 thedelta-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.
- Do not specify the
- Rerun the previous command without the
--dry-run
flag to install the service.
Verifying that the installation completed successfully
From your installation node:
- 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.
