loumaris/kubectl

A small helper image to run kubectl inside a CI like gitlab-ci.

usage

• encode your kubeconfig to a base64 string, e.g.

  cat ~/.kube/config | base64

• add the content to an env-variable called KUBECONFIG_BASE64
• run a kubectl command, e.g.

  docker run -e KUBECONFIG_BASE64='....' loumaris/kubectl get nodes

That's it ;-)

gitlab-ci usage

• see the usage
• add the base64 string to your gitlab-ci configuration
