Sometimes you may not want to install Docker with the wonderfully useful
curl -sSL https://get.docker.com/ | sh, so here's a few options for being more literal with your engine install, which I've got in a gist, also seen below.
Things it does above and beyond:
- Uninstalls LXC, which comes default in Ubuntu 16.04 and you don't need if you're using Docker. Packages removed include
lxc-common lxcfs lxd lxd-client
- Enables User Namespaces. IMO it's a great feature to turn on in most cases so your containers don't run as root on the host. This is the
--userns-remap=defaultpart. More info on the internals in a Docker KB, but usually it just works.
- Changes to
overlay2storage driver (not yet the default), so if you want something else then you'll want to change this up a bit. This is enabled by simply adding
--storage-driver overlay2. Note it requires the newer 4.x kernel of Ubuntu 16.04.
