  Copy

• set environment variable K8S_CONFIG to the base64 value of the Kubernetes config

  • as described e.g. .../kubernetes/README_kubernetes_for_gitlab-ci.md:

    export K8S_CONFIG=YXBpVmVyc...
    

    Copy

• start the Docker container (alternatively in CI or in Kubernetes):

  sudo docker run -it -e K8S_CONFIG=$K8S_CONFIG hapkecom/kubectl-docker-image:latest /bin/bash
  

  Copy

• run inside the Docker container (alternatively in CI or in Kubernetes):

  # first initialization:
  mkdir ~/.kube
  echo $K8S_CONFIG | base64 -d > ~/.kube/config
  

  Copy

  and

  # then run scripts or kubectl directly
  kubectl get namespaces
