# 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
|
|
```bash
|
|
docker run -ti --privileged whindes/alpine-minikube sh
|
|
```
|
|
|
|
## Minikube
|
|
|
|
After the commands below navigate to http://<your_host_docker>:30000/#!/overview?namespace=default
|
|
|
|
```bash
|
|
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
|
|
|
|
```bash
|
|
docker run --name alpine-docker -p 2375:2375 --privileged -d whindes/alpine-minikube
|
|
```
|
|
|
|
To start a shell in your new container.
|
|
|
|
```bash
|
|
docker exec -ti alpine-docker /bin/sh
|
|
```
|
|
|
|
## Inside the container shell
|
|
|
|
Now you can start containers inside your alpine-docker container.
|
|
|
|
```bash
|
|
docker run -d elasticsearch
|
|
docker images
|
|
docker ps -a
|
|
docker volume ls
|
|
```
|
|
|
|
## Docker-compose
|
|
|
|
If you need docker-compose inside your alpine-docker container.
|
|
```bash
|
|
setup-compose
|
|
docker-compose up
|
|
```
|
|
|
|
## Remote docker
|
|
|
|
Set your client system variables and go
|
|
```bash
|
|
export DOCKER_API_VERSION=1.23
|
|
export DOCKER_HOST='tcp://127.0.0.1:2375'
|
|
docker ps
|
|
docker-compose up
|
|
```
