Kubectl in a docker

The prupose of this tool is to have a subset of commands totally portable to operate a k8s cluster. This is heavily inspired by the kubectl-container

What does it include

The default container image includes the follwing tools:

• kubectl: k8s command line
• awscli: AWS command line
• krew: plugins manager for kubectl (with default plugins already setup)
• yq: same as jq but for YAML file (ex: kubectl get endpoints mongodb-staging-svc -o yaml | yq)
• k9s: k8s dashboarding tools
• fzf: Fuzzy search
• helm: k8s package manager
• velero: velero command line
• direnv: in case you would like to customized your ${HOME}

Bash completion:

Bash completion is available for:

• kubectl
• fzf

Bash PS1

To have a better visibility when handling you k8s cluster kube_ps1 is also used for your prompt.

Use your favorite docker image builder (in the example buildah)

 buildah bud --format docker -t docker.io/localregistry/kubectl-container:$(date "+%Y%m%d") Dockerfile

How to use it

Just use your favorite container orchestrator (in the example podman)

podman run --rm --name kubectl$(basename $(tty)) --tty=true --interactive --volume ~/.aws:/root/.aws --volume ~/.kube:/root/.kube docker.io/localregistry/kubectl-container:20220913
