GitLab CI

When using vCluster.Pro with GitLab you can use the official image ghcr.io/loft-sh/vcluster-cli as either a base image or directly. If additional tooling is needed for your CI/CD process, a custom image can be created.

Virtual Clusters for Merge Requests​

This example shows how to create and delete a Virtual Cluster for running end-to-end tests for the default branch and merge requests. It assumes you have configured CI/CD variables VCLUSTER_PRO_URL and VCLUSTER_PRO_ACCESS_KEY.

image: ghcr.io/loft-sh/vcluster-cli

stages:
  - test

e2e:
  rules:
    - if: $CI_MERGE_REQUEST_IID
    - if: $CI_COMMIT_BRANCH == $CI_DEFAULT_BRANCH
  stage: test
  before_script:
    - vcluster login $VCLUSTER_PRO_URL --access-key $VCLUSTER_PRO_ACCESS_KEY
    - vcluster create "${CI_PROJECT_NAME}-${CI_COMMIT_SHORT_SHA}-${CI_PIPELINE_ID}" --upgrade
    - apk add go make
  script:
    - kubectl apply -Rf ./kubernetes
    - kubectl rollout status deployments/my-app
    - make e2e
  after_script:
    - vcluster delete "${CI_PROJECT_NAME}-${CI_COMMIT_SHORT_SHA}-${CI_PIPELINE_ID}" --delete-namespace

Explanation:

  1. The ghcr.io/loft-sh/vcluster-cli image is used for all pipeline jobs and provides the vcluster CLI, the devspace CLI, helm, and kubectl.
  2. The before_script first logs in to vCluster.Pro using the $VCLUSTER_PRO_URL and $VCLUSTER_PRO_ACCESS_KEY variables that you defined in GitLab. See the GitLab docs for more information
  3. The before_script then creates a virtual cluster using predefined GitLab variables to create a unique name. Optionally, the --upgrade flag can be used to reuse an existing virtual cluster instead of creating a new one.
  4. Next before_script installs some additional tooling needed to run the end-to-end tests. For more complex scenarios creating a custom image is recommended.
  5. Then the script section uses kubectl to deploy the application to the space and waits for the my-app deployment to become ready. make is then used to run an end-to-end test suite.
  6. Finally after_script deletes the virtual cluster, and passes --delete-namespace to ensure the corresponding namespace for the virtual cluster is deleted. By using after_script we can ensure the virtual cluster is deleted even if the tests fail. You may wish to skip this step if reusing the virtual cluster with the --upgrade flag when creating the virtual cluster.
