Kubernetes Utilities

This project contains Kubernetes related utilities for use in build/deploy pipelines that have docker.

The following utilities are included:

• kubectl is a CLI tool to manage a Kubernetes cluster
• kops - CLI tool to create, destroy, upgrade Kubernetes clusters in cloud service providers
• helm - Kubernetes packaging/deployment tool

Why use it

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 or other cli tools to be installed; only Docker.
• To avoid kubectl config use-context and similar to affect your build and other projects' builds.

Usage

$ docker run --rm bartlettc22/kubectl kubectl --help

Usage example 1

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

$ docker run --rm --net=host --user $UID \
    -v ~/.kube:/config/.kube \
    cbartlett22/kubectl kubectl cluster-info

Usage: kubectl

docker run --rm -it \
  -v ${HOME}/.aws:/config/.aws \
  -e "AWS_PROFILE=$AWS_PROFILE" \
  -e "KOPS_NAME=blue.testcluster.io" \
  -e "KOPS_STATE_STORE=s3://kubectl-state" \
  bartlettc/docker-kubectl \
  sh -c "kops export kubecfg --name \$KOPS_NAME; kubecfg version"
