docker-kube-sandbox

Docker in Docker image with shellinabox, kubectl and git based on docker image https://cloud.docker.com/repository/docker/mchebitou/docker-kube-sandbox

Why?

Recently I had to build a lab for initiating new users to the use of Docker and Kubernetes, I needed a quick way to give those users access to a ready to use environment with all the necessary tools and enough security to make sure they don't break anything. To make this image I took fhuegli/docker-shellinabox, rebased it on Docker official image and adapted it to suit my need.

Install on Kubernetes

$ kubectl apply -f kubernetes/configmap.yaml
$ kubectl apply -f kubernetes/secret
$ kubectl apply -f kubernetes/deployment.yaml
$ kubectl apply -f kubernetes/service.yaml

Default credentials to be used for login are :

username: docker
password: secret
