I want to run a command on a docker container that has kubectl installed but not yet configured.
On my local machine, I have my kubectl authenticated and configured to communicate with a kubernetes cluster on Google Cloud.
If I run the command:
docker run mycontainerimage kubectl get podsI'll get the response:
invalid configuration: no configuration has been providedHow can I pass my kubernetes credentials/configuration into the docker image running on my local machine? Thanks!
Actually, the Kubectl Configuration/authentification depends on many resources and symlinks in the environment to connect to the cluster.
I think the best and the most secured solution is to configure a VPN that provides secure remote SSH access in the cluster and connect to the API-Server Remotely.
Kubernetes support SocketXP, here is a step-by-step guide about how to Configure local kubectl to access remote Kubernetes cluster.
You can mount your config file with -v into the container
docker run -v ~/.kube/config:/kube/config ...and set the environment variable KUBECONFIG
docker run -v ~/.kube/config:/kube/config --env KUBECONFIG=/kube/config ...now every kubectl call should use the mounted config file.
