何时升级 Docker（以及如何操作）？

Is 17.06 still the recommended? We’re on 17.10.0-ce ourselves.

If you’ve installed via apt it’s relatively straightforward, uninstall, reboot:

sudo apt-get autoremove -y docker-ce \ 
& sudo apt-get purge docker-ce -y \ 
& sudo rm -rf /etc/docker/ \ 
& sudo rm -f /etc/systemd/system/multi-user.target.wants/docker.service \ 
& sudo rm -rf /var/lib/docker \ 
& sudo systemctl daemon-reload

then use:

sudo apt-cache policy docker-ce

to see which versions are available to apt, and then:

sudo apt-get install -y docker-ce=[build string]

to install a specific version.

Checking our install we can see builds ranging from 17.04.0-ce all the way up to 18.04.0-ce:
