Gitlab Project Variables
External Secrets Operator integrates with Gitlab API to sync Gitlab project variables to secrets held on the Kubernetes cluster.
Authentication
The API requires an access token and project ID. To create a new access token, go to your user settings and select 'access tokens'. Give your token a name, expiration date, and select the permissions required (Note 'api' is required).
Click 'Create personal access token', and your token will be generated and displayed on screen. Copy or save this token since you can't access it again.
Access Token secret
Create a secret containing your access token:
{% include 'gitlab-credentials-secret.yaml' %}
Update secret store
Be sure the gitlab provider is listed in the Kind=SecretStore and the ProjectID is set. If you are not using https://gitlab.com, you must set the url field as well.
{% include 'gitlab-secret-store.yaml' %}
NOTE: In case of a ClusterSecretStore, Be sure to provide namespace in accessToken with the namespace where the secret resides.
Your project ID can be found on your project's page.
Creating external secret
To sync a Gitlab variable to a secret on the Kubernetes cluster, a Kind=ExternalSecret is needed.
{% include 'gitlab-external-secret.yaml' %}
Using DataFrom
DataFrom can be used to get a variable as a JSON string and attempt to parse it.
{% include 'gitlab-external-secret-json.yaml' %}
Getting the Kubernetes secret
The operator will fetch the project variable and inject it as a Kind=Secret.
kubectl get secret gitlab-secret-to-create -o jsonpath='{.data.secretKey}' | base64 -d
