This repo is forked from https://github.com/lauriku/docker-kubectl

kubectl is a CLI tool to control a cluster Kubernetes.

$ docker run --rm silenthoo/docker-kubectl --help

Note: Entrypoint is set to kubectl so do not type silenthoo/kubectl kubectl.

For example to access a local Kubernetes cluster you may run:

$ docker run --rm --net=host --user $UID \
    -v ~/.kube:/config/.kube \
    silenthoo/kubectl cluster-info

• --net=host: (optional) allows to connect to a local Kubernetes cluster.
• --user $UID: (optional) by default runs as random UID 2342, this allows to access your existing ~/.kube if you have one. As you can note, you can run kubectl as any UID/GID.
• -v XXX:/config: (optional) allows to store its configuration and possibly access existing configuration. Note that /config will always be the directory containing .kube (it's the forced HOME directory). Can be read-only. Alternatively you can mount a Kubernetes service account for example: -v /var/run/secrets/kubernetes.io/serviceaccount:/var/run/secrets/kubernetes.io/serviceaccount:ro.

It's mostly meant to be used during continuous integration or as part of an automated build/deployment:

• So that your machine (e.g. build server) doesn't need kubectl to be installed; only Docker.
• To avoid kubectl config use-context and similar to affect your build and other projects' builds.

• Change the Dockerfile
• Tag: docker build -t silenthoo/docker-kubectl:1.9.4 -t silenthoo/docker-kubectl: latest .
• Push: docker push silenthoo/docker-kubectl
