Kubectl is a fantastic tool. Typically, users run it locally where it makes requests over the network to a remote cluster. This is fine most of the time, but in some cases you may want kubectl to run inside the cluster.
This project provides a Dockerfile to generate images that contain kubectl with various versions and a Go package to run arbitrary commands in the container that has kubectl.
It can also push images to my Dockerhub account. To see all availabl images type:
$ curl -s "https://hub.docker.com/v2/repositories/g1g1/kubectl/tags?page_size=100" | jq '.results[].name' | sort
"1.21"
"1.22"
"1.23"
"1.24"
"1.25"
"1.26"
You can pull existing images without building by typing:
docker pull g1g1/kubectl:<tag>
To build your own image for a particular version of kubectl change the VERSION at the top of the Makefile
and type make.
The make push command pushes the image to my Dockerhub account. If you want to push to your registry change the IMAGE variable in the Makefile.
