This is a secure ssh server setup based on a blog post by @stribika:
Includes git,vim,zsh,tmux because I like them.
Things to know:
Mount your entire $HOME directory to /home/ssher so you get all your keys and rc dotfiles.
Do not try to ssh as root, instead use: "ssh ssher@hostname" with a key.
You should probably build this yourself, if you cared enough to read that blog post.
docker run --name="sshd" -v /etc/localtime:/etc/localtime:ro -v $HOME:/home/ssher -p 22022:22 -d presentgear/sshd:latest
