Group-wide Kubernetes Cluster, missing variables in CI

Summary

When using group-wide Kubernetes Cluster the deployment stage is missing some kubernetes configuration variables.

Steps to reproduce

Create a group-wide kubernetes cluster and create a project with the following .gitlab-ci.yml:

stages:
  - deploy

deploy:
  stage: deploy
  image: lachlanevenson/k8s-kubectl:latest
  script:
    - echo $KUBE_NAMESPACE
    - echo $KUBE_URL
    - echo $KUBECONFIG
    - cat $KUBECONFIG
    - echo $KUBE_TOKEN
  environment:
    name: production
    url: https://test.test.tld
  only:
    - master

What is the current bug behavior?

Variables like KUBE_NAMESPACE and KUBE_TOKEN are missing/empty

What is the expected correct behavior?

All variables should be filled correctly and kubectl should be able to make a connection to the cluster

Relevant logs and/or screenshots

$ echo $KUBE_NAMESPACE

$ echo $KUBE_URL
https://kubernetes.coco.local:6443
$ echo $KUBECONFIG

$ cat $KUBECONFIG
$ echo $KUBE_TOKEN

Output of checks

  • Namespaces was created by GitLab
