Start Sandbox Host

git clone https://github.com/ryanckoch/ansible-sandbox-docker.git && \
cd ansible-sandbox-docker && \
./init.sh ubuntu_16.04 username password

Add the following to your SSH config

Host 127.0.0.1.nip.io
  Port 2222
  UserKnownHostsFile /dev/null
  StrictHostKeyChecking no
  PasswordAuthentication no

You should now be able to SSH to your host and in turn run ansible against it

ssh 127.0.0.1.nip.io
