Setting up the cluster for Watson Discovery
If you plan to install Watson Discovery on IBM® Cloud Pak for Data, a cluster administrator must set up the cluster for Watson Discovery.
Before you begin
Required role: To complete this task, you must be a cluster administrator.
Before you set up the cluster for Watson Discovery, ensure that:
- 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 Watson Discovery. For details, see System requirements for services.
- The machine from which you will run the commands meets the requirements described in Preparing your installation node.
- On air-gapped clusters: You completed the steps in Preparing for air-gapped installations to download the required files for the service.
./cpd-cli adm --help
storageclass
parameters when you install
Cloud Pak for Data and Watson Discovery. - When you install Cloud Pak for Data, specify
--storageclass ocs-storagecluster-cephfs
. - When you install Watson Discovery, specify
--storageclass ocs-storagecluster-ceph-rbd
.
Procedure
- Set up the cluster for Watson Discovery by completing the appropriate task for your environment:
- Complete the tasks listed in What to do next
Preparing 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 an
administrator:
oc login OpenShift_URL:port
- Run the
following command to see a preview of the list of resources that must be created on the
cluster:
./cpd-cli adm \ --repo ./repo.yaml \ --assembly watson-discovery \ --arch Cluster_architecture \ --namespace Project \ --latest-dependency
Important: By default, this command gets the latest version of the assembly. If you want to install a specific version of Watson Discovery, add the following line to your command after the--assembly
flag:--version Assembly_version \
Additionally, you can remove the
--latest-dependency
flag to get the minimum required version of any software that Watson Discovery is dependent on.Tell the person who will install Watson Discovery whether you used either of these flags. The
install
command must be run with the same flags.Replace the following values:
Variable Replace with Assembly_version The version of Watson Discovery 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
- For IBM Z hardware, specify s390x
Project The project where the Cloud Pak for Data control plane is installed. The command returns a list of the changes that you must make to your cluster to ensure that Watson Discovery can run on your cluster.
- Make the
necessary changes to your cluster. You can choose one of the following methods to make the
changes:
- To automatically apply the changes to your cluster:
- Re-run the
cpd adm
command with the--apply
flag:./cpd-cli adm \ --repo repo.yaml \ --assembly watson-discovery \ --arch Cluster_architecture \ --namespace Project \ --apply
Replace the variables with the same values that you used the last time you ran the command.
- To manually apply the changes to your cluster:
- Follow the appropriate procedures from the Red Hat OpenShift documentation to complete the required tasks.
Preparing air-gapped clusters
From your installation node:
- Change to the directory where you placed the Cloud Pak for Data command-line interface.
- Log in to your Red Hat OpenShift cluster as an
administrator:
oc login OpenShift_URL:port
- Run
the following command to see a preview of the list of resources that must be created on the
cluster:
./cpd-cli adm \ --assembly watson-discovery \ --arch Cluster_architecture \ --namespace Project \ --load-from Image_directory_location \ --latest-dependency
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.Tell the person who will install Watson Discovery whether you used the
--latest-dependency
flag. If you run this command with the--latest-dependency
flag, theinstall
command must also be run with the flag.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
- For IBM Z hardware, specify s390x
Project The project where the Cloud Pak for Data control plane is installed. Image_directory_location The location of the cpd-cli-workspace directory. The command returns a list of the changes that you must make to your cluster to ensure that Watson Discovery can run on your cluster.
- Make the
necessary changes to your cluster. You can choose one of the following methods to make the
changes:
- To automatically apply the changes to your cluster:
- Re-run the
cpd adm
command with the--apply
flag:./cpd-cli adm \ --assembly watson-discovery \ --arch Cluster_architecture \ --namespace Project \ --load-from Image_directory_location \ --latest-dependency \ --apply
Replace the variables with the same values that you used the last time you ran the command.
- To manually apply the changes to your cluster:
- Follow the appropriate procedures from the Red Hat OpenShift documentation to complete the required tasks.
