Running Instructions

You can run this container with just a shell for interactive access with

docker run -it raesene/alpine-containertools /bin/bash

Alternatively if you don't specify a command it'll launch an SSH server with a random password. To use this with a docker image first, docker run -d -p 3456:22 raesene/alpine-containertools then docker ps to get the container name, then docker logs <container> to get the root password, then ssh root@<ip>

The SSH setup was based on ideas from https://github.com/fedora-cloud/Fedora-Dockerfiles/blob/master/ssh/entrypoint.sh and https://github.com/sickp/docker-alpine-sshd/blob/master/versions/7.4/Dockerfile
