Docker update to latest version

[Architect]

From that guide referenced above:

@Discourse

Due to the way docker packaging has changed you may also have to update your docker from lxc-docker or docker-engine packages. One way to do that is via the Docker script here (it will warn about an existing install but should upgrade ok):

wget -qO- https://get.docker.com/ | sh

This will now use the docker-ce main versions.

Edit: This command seems to have caused site to crash, don’t recommend running that.
