- Installing the GitLab Operator
- Uninstall the GitLab Operator
This document describes how to deploy the GitLab Operator via manifests in your Kubernetes or OpenShift cluster.
If using OpenShift, these steps normally are handled by OLM (the Operator Lifecycle Manager) once an operator is bundle published. However, to test the most recent operator images, users may need to install the operator using the deployment manifests available in the operator repository.
Please consult the “Prerequisites” section of the installation page.
Clone the GitLab Operator repository to your local system.
git clone https://gitlab.com/gitlab-org/cloud-native/gitlab-operator.git cd gitlab-operator
Build CRDs and Operator manifests:
task build_operatorIn some cases, you may run into issues resolving dependencies and see an error message such as:
go get: email@example.com+incompatible: invalid version: unknown revision v3.9.0
To address this, configure
GOPROXYas mentioned in this issue:
Deploy the GitLab Operator.
PLATFORM=kubernetes # or "openshift" kubectl create namespace gitlab-system task deploy_operator # or "task deploy_operator_openshift"
This command first deploys the service accounts, roles and role bindings used by the operator, and then the operator itself.
Create a GitLab custom resource (CR).
Create a new file named something like
Here is an example of the content to put in this file:
apiVersion: apps.gitlab.com/v1beta1 kind: GitLab metadata: name: gitlab spec: chart: version: "X.Y.Z" # select a version from the CHART_VERSIONS file in the root of this project values: global: hosts: domain: example.com # use a real domain here ingress: configureCertmanager: true certmanager-issuer: email: firstname.lastname@example.org # use your real email address here
For more details on configuration options to use under
spec.chart.values, see our GitLab Helm Chart documentation.
Deploy a GitLab instance using your new GitLab CR.
kubectl -n gitlab-system apply -f mygitlab.yaml
This command sends your GitLab CR up to the cluster for the GitLab Operator to reconcile. You can watch the progress by tailing the logs from the controller pod:
kubectl -n gitlab-system logs deployment/gitlab-controller-manager -c manager -f
You can also list GitLab resources and check their status:
kubectl get gitlabs -n gitlab-system
When the CR is reconciled (the status of the GitLab resource will be
RUNNING), you can access GitLab in your browser at
Certain operations like file removal under
config/ directory may not trigger rebuild/redeploy, in which cases one should employ:
This will remove all of the build artifacts and the install record.
Follow the steps below to remove the GitLab Operator and its associated resources.
Items to note prior to uninstalling the operator:
- The operator does not delete the Persistent Volume Claims or Secrets when a GitLab instance is deleted.
- When deleting the Operator, the namespace where it is installed (
gitlab-systemby default) will not be deleted automatically. This is to ensure persistent volumes are not lost unintentionally.
kubectl -n gitlab-system delete -f mygitlab.yaml
This will remove the GitLab instance, and all associated objects except for (PVCs as noted above).
This will delete the Operator’s resources, including the running Deployment. It will not delete objects associated with a GitLab instance.
