# We can also deploy to a Hypernode Docker instance. To do that you go to

# have an instance running by for example doing:
# $ sudo docker run -P docker.hypernode.com/byteinternet/hypernode-buster-docker-php80-mysql57:latest
# and then noting the IP address (in my case 172.17.0.2). You then
# need to make sure your deploykey public key is added to the
# /data/web/.ssh/authorized_keys file. Then you should be able to
# deploy to the container as if it was a 'real' hypernode. Keep in
# mind that the hypernode-docker is not a real VM, it's just a fat
# container. This means that there won't be an init system (no systemd)
# so the processes are running in SCREENs. Also obviously you can not use
# some of the hypernode command-line functionality that depends on the
# Hypernode API (it's not a server managed by the Hypernode automation,
# just a local container running on your PC).
