Usage

System Requirements

The ~700Mb image has an already created minkikube instance with 4Gb diskspace and 1Gb RAM. This is only for experimentation and demo only. Do not use in production. The minikube binary from the official repository does not work in Alpine and had to be built from source. (See Dockerfile)

Commandline

Starts a shell ready to docker & minikube

docker run -ti --privileged whindes/alpine-minikube sh

Minikube

After the commands below navigate to http://<your_host_docker>:30000/#!/overview?namespace=default

docker run -ti -p 30000 -p 31920 --rm --privileged whindes/alpine-minikube sh
[Hit Enter] to get the shell prompt
minikube start
kubectl run webserver --image=nginx:alpine
kubectl expose deployment webserver --type=LoadBalancer --port=80

Daemon

docker run --name alpine-docker -p 2375:2375 --privileged -d whindes/alpine-minikube

To start a shell in your new container.

docker exec -ti alpine-docker /bin/sh
