Release notes

Generally available in GitLab 14.10 is a GitLab Runner Operator for Kubernetes. The GitLab Runner Operator simplifies the installation and management of GitLab Runner on your target Kubernetes cluster.

Description

The operator was designed and released for OpenShift. It still doesn't support Kubernetes installations.

Proposal

Publish a GitLab Runner Operator for Kubernetes.

Status update

Solution 1: Modifying the operator project to support vanilla k8s

The modifications have been made by following this kubebuilder tutorial

Work done:

  • Support of the Webhook and CertManager in the operator CRD
  • Support of the MutatingWebhookConfiguration in the operator
  • Ability to deploy the Operator on both OpenShift and vanilla k8s with ENABLE_WEBHOOK set to false

Concerns:

  • certmanager required on cluster to install the operator (on both OpenShift and vanilla k8s)
  • Due to the use of the v1.18.0 of operator-sdk, the OwnNamespace installMode is no longer supported
    • ⚠ When using operator-sdk v1.5 on local machine to generate the bundle, this change is not needed

Questions:

Are the points listed in the concerns section going to negatively impact existing setup ?

Solution 2: CRDs duplication to avoid changes on OpenShift configurations

Work done:

  • Duplication of crd, default, manifests folders to implement vanilla k8s support
  • Implementation of vanilla k8s makefile commands

Concerns:

  • kustomize command fails to generate expected files

Notes:

  1. More context on the summary above can be found in the following thread
  2. The branch linked to this MR implements the solution 1
