clintainer

Docker Container loaded with a lot of K8s CLI's like kubectl, helm, istio and keptn preloaded with Oh My ZSH.

This image will be automatically build every week and is using the latest available releases of the tools.

If you need to work on a remote server and don't want to install all the tools manually, or for ad-hoc operation tasks.

Run clintainer on Docker

docker run -v ~/.kube/config:/home/operator/.kube/config -it checkelmann/clintainer

Cleanup

docker rmi checkelmann/clintainer

Run clintainer as cluster-admin in K8s

1. Create a clintainer service account with kubectl

kubectl create serviceaccount clintainer --namespace kube-system

2. Create a clintainer-rolebinding.yaml file with the following content

kind: ClusterRoleBinding
apiVersion: rbac.authorization.k8s.io/v1beta1
metadata:
  name: clintainer-clusterrolebinding
subjects:
- kind: ServiceAccount
  name: clintainer
  namespace: kube-system
roleRef:
  kind: ClusterRole
  name: cluster-admin
  apiGroup: ""

3. Deploy the rolebinding

kubectl apply -f clintainer-rolebinding.yaml

4. Run clintainer

kubectl run clintainer -n kube-system --image=checkelmann/clintainer -it --rm --restart=Never --serviceaccount=clintainer

5. Cleanup

kubectl delete -f clintainer-rolebinding.yaml
kubectl delete serviceaccount clintainer --namespace kube-system

All in one (if you trust external Manifests)

kubectl create serviceaccount clintainer --namespace kube-system
kubectl apply -f https://raw.githubusercontent.com/checkelmann/clintainer/main/rolebinding.yaml
kubectl run clintainer -n kube-system --image=checkelmann/clintainer -it --rm --restart=Never --serviceaccount=clintainer
kubectl delete -f https://raw.githubusercontent.com/checkelmann/clintainer/main/rolebinding.yaml
kubectl delete serviceaccount clintainer --namespace kube-system
