Setting up the cluster for Master Data Connect

If you plan to install Master Data Connect on IBM® Cloud Pak for Data, a cluster administrator must set up the cluster for Master Data Connect.

Before you begin

Required role: To complete this task, you must be a cluster administrator.

Before you set up the cluster for Master Data Connect, ensure that:

Tip: For a list of all available options, enter the following command:
./cpd-cli adm --help

Procedure

  1. Set up the cluster for Master Data Connect by completing the appropriate task for your environment:
  2. Complete the tasks listed in What to do next

Preparing 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 an administrator:
    oc login OpenShift_URL:port
  3. 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 mdc \
    --arch Cluster_architecture \  
    --namespace Project

    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
    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 Master Data Connect can run on your cluster.

  4. 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 mdc \
    --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:

  1. Change to the directory where you placed the Cloud Pak for Data command-line interface.
  2. Log in to your Red Hat OpenShift cluster as an administrator:
    oc login OpenShift_URL:port
  3. Run the following command to see a preview of the list of resources that must be created on the cluster:
    ./cpd-cli adm \
    --assembly mdc \
    --arch Cluster_architecture \
    --namespace Project \
    --load-from Image_directory_location \
    --latest-dependency

    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
    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 Master Data Connect can run on your cluster.
