Recommended way to install Docker in Stretch

[Luís Gomes <luismsgomes@gmail.com>]

Hello everyone,

I'm setting up a server with Debian Stretch and I need to install
Docker.

After reading the warning against installing software from unnoficial
repositories from https://wiki.debian.org/DontBreakDebian I'm trying to
follow this good advice.

However, I could not find a docker.io package on the main stretch
repository or in stretch-backports, which makes me ask what is the
Debian-recommended-way to install Docker on Stretch?


Thanks,

Luís
