Create custom cluster
In concourse we have the ability to create custom clusters based of whichever branch you specify.
First we need to update the pipeline config with our branch, you need to run the following command from the cloud-platform-terraform-concourse repo root folder.
fly -t moj-cp set-pipeline --pipeline custom-cluster --config pipelines/manager/main/custom-cluster.yaml -v branch_name=migrate-eks-csi
From here you can then kick off the build from the concourse UI.
Deleting your custom cluster
Our delete pipeline allows you to specify the branch_name in the config so to do this you run:
fly -t moj-cp set-pipeline --pipeline delete-cluster --config pipelines/manager/main/delete-cluster.yaml -v branch_name=migrate-eks-csi -v cluster_name=tp-0000-0000
You need to pass both branch_name and cluster_name to the command.
 Rerunning stages in the create custom cluster pipeline
If you need to re-run a plan or apply at any stage after the cluster has been created you can do this by running the following:
fly -t moj-cp set-pipeline --pipeline custom-cluster --config pipelines/manager/main/custom-cluster.yaml -v branch_name=migrate-eks-csi -v cluster_name=tp-0000-0000
Then you can select the step in the pipeline that you’d like to re-run.
Run integration tests against custom cluster
You can also use the custom-integration-tests job within the custom-cluster pipeline to execute the go integration test suite against a cluster of your choice:
fly -t manager set-pipeline -p custom-cluster -c pipelines/manager/main/custom-cluster.yaml -v branch_name=<SOME-OTHER-BRANCH> -v cluster_name=<YOUR-TEST-CLUSTER-NAME>
And then trigger a new build in custom-integration-tests job view.
