Create Migration Environment

• Create hosted Zones:
  • jpdv.aws.kerbeross.com depends on aws.kerbeross.com
  • hc.jpdv.aws.kerbeross.com depends on jpdv.aws.kerbeross.com
  • guest.jpdv.aws.kerbeross.com depends on jpdv.aws.kerbeross.com

Create Clusters

Dev will be the Source Management Cluster

/Users/jparrill/RedHat/RedHat_Engineering/hypershift/repos/hypershift/bin/hypershift create cluster aws --aws-creds ~/.aws/credentials --instance-type m6i.xlarge --region us-west-1 --auto-repair --generate-ssh --name jparrill-dev --namespace jparrill --base-domain jpdv.aws.kerbeross.com --node-pool-replicas 2 --pull-secret /Users/jparrill/RedHat/RedHat_Engineering/pull_secret.json --release-image quay.io/openshift-release-dev/ocp-release:4.12.0-rc.1-x86_64; sleep 120;mkdir -p /Users/jparrill/RedHat/RedHat_Engineering/hypershift/hosted_clusters/jparrill-jparrill-dev && /Users/jparrill/RedHat/RedHat_Engineering/hypershift/repos/hypershift/bin/hypershift create kubeconfig --name jparrill-dev --namespace jparrill > /Users/jparrill/RedHat/RedHat_Engineering/hypershift/hosted_clusters/jparrill-jparrill-dev/kubeconfig

Dest will be the Destination Management Cluster

/Users/jparrill/RedHat/RedHat_Engineering/hypershift/repos/hypershift/bin/hypershift create cluster aws --aws-creds ~/.aws/credentials --instance-type m6i.xlarge --region us-west-1 --auto-repair --generate-ssh --name jparrill-dest --namespace jparrill --base-domain jpdv.aws.kerbeross.com --node-pool-replicas 2 --pull-secret /Users/jparrill/RedHat/RedHat_Engineering/pull_secret.json --release-image quay.io/openshift-release-dev/ocp-release:4.12.0-rc.1-x86_64; sleep 120; mkdir -p /Users/jparrill/RedHat/RedHat_Engineering/hypershift/hosted_clusters/jparrill-jparrill-dest && /Users/jparrill/RedHat/RedHat_Engineering/hypershift/repos/hypershift/bin/hypershift create kubeconfig --name jparrill-dest --namespace jparrill > /Users/jparrill/RedHat/RedHat_Engineering/hypershift/hosted_clusters/jparrill-jparrill-dest/kubeconfig

Perform the Migration

To execute the migration I use this bash script which delegates the variables in this common file
