returnpath/kubectl repository overview

⁠About

This is a minimal image containing (effectively) just kubectl⁠ designed to be used as kubectl available as returnpath/kubectl⁠.

⁠Usage

Since ENTRYPOINT is set to kubectl you just need to run the container as if it's the kubectl executable:

docker run returnpath/kubectl

However you haven't specified --server so it'll default to localhost:8080: If kubernetes is running on localhost:8080 just call docker with --net=host:

docker run --rm --net=host returnpath/kubectl

If kubernetes isn't on localhost:8080 you can use --server like normal, or, if you have ~/.kube/config volume mount that into the container:

docker run --rm -v ~/.kube:/root/.kube returnpath/kubectl

If you're going to be using this regularly you should create a shell alias so all the docker configuration is obfuscated and you can really think of the container just like you would the local executable:

alias kubectl='docker run --rm -v ~/.kube:/root/.kube returnpath/kubectl'

This allows you to use kubectl as if it were installed locally, so to list running pods it's simply:

kubectl get pods

Note the --rm in the above commands: This removes the container after the command exits and prevents old containers from collecting each time you run kubectl.

The commands above will use the latest version of kubectl that's been pushed up, but you can specify which version by tage. To run kubectl version 1.2.3 it's:

docker run --rm returnpath/kubectl:1.2.3

The image tags are created from the github tags.
