Installing Red Hat Advanced Cluster Management

Assumptions:

  • You have access to a AWS account and are using IPI to install
  • You have a generated public ssh key
  • You have already downloaded the IPI installation program here needed for the OCP install
  • You have already created a pull secret here
  • You have already created a service registry account here
  • You have created project open-cluster-management

Required steps:

  1. Configure aws cli for account

    • We need to run the aws command to configure the aws account we want to use on the command line. If you are not familiar with this please see here

    • Once you have the profile configured for the correct account you want to deploy you can run the following command:

      export AWS_PROFILE=YourProfileHere

  2. Install the Hub and managed OCP clusters

    • Modify the install.yaml files located int acm-test-cluster-hub, acm-test-cluster-managed, and acm-test-cluster-managed-2 with your pull secret and ssh public key

    • Create the hub cluster by running the following command

      • ./openshift-install create cluster --dir=acm-test-cluster-hub --log-level=debug

    • Create the managed clusters by running the following command

      • ./openshift-install create cluster --dir=acm-test-managed --log-level=debug
      • ./openshift-install create cluster --dir=acm-test-managed-2 --log-level=debug
      • Once the manage cluster is up add label cluster = test-cluster-managed

  3. Create secret needed for for registry. You should have pulled the yaml file when you created the service registry account. See assumptions if this is unclear

    • Log into the hub cluster on the command line

    • Run the following command to create the secret from the yaml file

      • oc create -f yourSecretHere.yaml --namespace=open-cluster-management

  4. Apply ACM operator group via yaml file

    • oc apply -f acm-operator.yaml

  5. Apply ACM subscription via yaml file

    • oc apply -f acm-subscription.yaml

  6. Create multiClusterHub via yaml file

    • oc apply -f ../Training\ Material/ACM/multicluster-acm.yaml

  7. Add managed cluster to Hub cluster

    • Log into ACM

      • You can do this by getting the route in the OCP cluster that is used for the hub

    • Once you are logged in

      • Select the top right drop down
      • Select Automate infrastructure
      • Select Clusters
      • Select Add cluster in drop down
      • Select Import an existing cluster

    • Generate Command

      • Configuration
        • Cluster name: acm-test-cluster-managed
      • Labels
        • Cloud: AWS
        • Environment: dev
        • additional lables: cluster = test-cluster-managed

  8. Confirm you see new cluster in Hub
