Set up environment

Set up Podman

podman login registry.gitlab.com

Set up Docker

If you’re not using podman for all tasks, authorize Docker to access registry.gitlab.com:

docker login registry.gitlab.com

Set up Git

Ensure user.name and user.email are configured in Git.

For additional variables look at Provision and deploy and OperatorHub publishing

Create test_olm.env in Operator’s root dir (or point to a file in a custom location using ${OLM_TESTING_ENVIRONMENT} environment variable)

Make sure to confirm every following customization line reflects your personal setup:

export OPERATOR_VERSION="0.10.2"
export OPERATOR_SDK="${HOME}/bin/operator-sdk_linux_amd64"
export BUNDLE_REGISTRY="registry.gitlab.com/dmakovey/gitlab-operator-bundle"

export PREVIOUS_OPERATOR_VERSION="0.9.1"
export LOCAL_IP="192.168.3.194"
export DO_NOT_PUBLISH="yes" # do not re-compile and publish bundle/catalog
                            # use the ones already published

Prepare KinD Cluster (Optional)

To run tests in KinD cluster with OLM set up:

scripts/test_olm.sh setup_kind_cluster

Otherwise current kubectl context should point to an existing cluster that has OLM pre-installed

Running tests

  1. Setup KinD cluster and deploy Operator there:

    scripts/test_olm.sh upgrade_test_step1
    

    Operator Pod should be up and running. Confirm by running:

    kubectl get pod -n gitlab-system -l control-plane=controller-manager
    
  2. Deploy “old” version of GitLab via Operator:

    scripts/test_olm.sh upgrade_test_step2
    

    Confirm GitLab has been deployed:

    kubectl get -n gitlab-system gitlab
    
  3. Upgrade the Operator:

    scripts/test_olm.sh upgrade_test_step3
    

    Confirm that Operator has been upgraded.

    Wait for the install to roll out before next step

  4. Upgrade GitLab:

    scripts/test_olm.sh upgrade_test_step4
    

    Confirm that GitLab has been upgraded and is functional

    Wait for the upgrade to complete

  5. Confirm GitLab is running:

    scripts/test_olm.sh check_gitlab
    

    above will query Operator for GitLab status, alternatively use

    scripts/test_olm.sh check_gitlab2
    

    which bypasses Operator checks and runs checks against GitLab instance itself.
