This workshop provides an introduction to deploying a Couchbase cluster using the Couchbase operator. Use of the operator is from the perspective of a developer.

The workshop uses the HomeRoom workshop environment in the learning portal configuration. You will need to be a cluster admin in order to deploy it.

When the URL for the workshop environment is accessed, a workshop session will be created on demand. This will include a project for the session, into which the Couchbase operator will have been pre-installed.

To deploy the workshop, first clone this Git repository to your own machine.

Next create a project in OpenShift into which the workshop is to be deployed.

oc new-project workshops

From within the top level of the Git repository, now run:

./scripts/deploy-spawner.sh

The name of the deployment will be couchbase-lab.

You can determine the hostname for the URL to access the workshop by running:

oc get route couchbase-lab

The deployment created above will use a version of the workshop which has been pre-built into an image and which is hosted on quay.io.

To make changes to the workshop content and test them, edit the files in the Git repository and then run:

./scripts/build-workshop.sh

This will replace the existing image used by the active deployment.

If you are running an existing instance of the workshop, from your web browser select "Restart Workshop" from the menu top right of the workshop environment dashboard.

When you are happy with your changes, push them back to the remote Git repository. This will automatically trigger a new build of the image hosted on quay.io.

If you need to change the RBAC definitions, or what resources are created when a project is created, change the definitions in the templates directory. You can then re-run:

./scripts/deploy-spawner.sh

and it will update the active definitions.

Note that if you do this, you will need to re-run:

./scripts/build-workshop.sh

to have any local content changes be used once again as it will revert back to using the image on quay.io.

To delete the spawner and any active sessions, including projects, run:

./scripts/delete-spawner.sh

To delete the build configuration for the workshop image, run:

./scripts/delete-workshop.sh

To delete special resources for CRDs and cluster roles for the Couchbase operator, run:

./scripts/delete-resources.sh

Only delete these last set of resources if the Couchbase operator is not being used elsewhere in the cluster. Ideally this workshop environment should only be deployed in an expendable cluster, and not one which is shared for other work.
