Kubectl

Your k8s cluster swiss army knife, running in a container.

Why should you use this?

Because this kubectl image is :

• lightweight
• secure
• multi-arch

New stable versions will be built and pushed automatically by GitHub action workflow.

Quickstart

Prerequisites

Make sure you have a containerization software (e.g. Docker ) installed on your device :

$ docker version

Client: Docker Engine - Community
 Cloud integration: 1.0.14
 Version:           20.10.6
 API version:       1.41
 Go version:        go1.13.15
 Git commit:        370c289
 Built:             Fri Apr  9 22:46:45 2021
 OS/Arch:           linux/amd64
 Context:           default
 Experimental:      true
[...]

Take our image

Just pull the desired version from quay.io :

$ docker pull quay.io/clastix/kubectl:<desired_version>

OR

Build your image

running :

$ docker build . -t foo.io/bar/kubectl:<desired_version> --build-arg KUBECTL_VERSION=<desired_version> --build-arg TARGETARCH=<target_architecture>

or using make utility :

$ make docker-build

N.B. if you like, you can choose desired kubectl version and target architecture as follow :

$ export KUBECTL_VERSION=<desired_version>
$ export TARGETARCH=<target_architecture>

otherwise, Makefile will automatically retrieve its default values.

Launch a container

$ docker run --name kubectl quay.io/clastix/kubectl:v1.22.2 version

Client Version: version.Info{Major:"1", Minor:"22", GitVersion:"v1.22.2", GitCommit:"8b5a19147530eaac9476b0ab82980b4088bbc1b2", GitTreeState:"clean", BuildDate:"2021-09-15T21:38:50Z", GoVersion:"go1.16.8", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"21", GitVersion:"v1.21.5", GitCommit:"aea7bbadd2fc0cd689de94a54e5b7b758869d691", GitTreeState:"clean", BuildDate:"2021-09-15T21:04:16Z", GoVersion:"go1.16.8", Compiler:"gc", Platform:"linux/amd64"}

you can also use your own kubeconfig

$ docker run --name kubectl -v ~/.kube/config:/home/nonroot/.kube/config quay.io/clastix/kubectl:<desired_version> get nodes

NAME              STATUS   ROLES                  AGE   VERSION
controlplane-00   Ready    control-plane,master   13d   v1.21.5
controlplane-01   Ready    control-plane,master   13d   v1.21.5
controlplane-02   Ready    control-plane,master   13d   v1.21.5
worker-00         Ready    <none>                 13d   v1.21.5
worker-01         Ready    <none>                 13d   v1.21.5
worker-02         Ready    <none>                 13d   v1.21.5

Removal

To clean up, just :

1. Remove your kubectl container :

   $ docker rm kubectl

2. Remove your kubectl image :

   $ docker rmi -f quay.io/clastix/kubectl:<desired_version>
