Xenial 16.04 (LTS)

Trusty 14.04 (LTS)

Note: Artful 17.10 only supports Docker CE17.11 Edge and later versions, because Artful itself is also a transitional version released in October 2017

Confirmation of the release code, such as Artful

Devops@ubuntu:~$ lsb_release-csartfuldevops@ubuntu:~$

Hardware

Ubuntu's support for Docker CE is not only required for 64-bit OS, but also for x86 CPU. In addition to x86, there are the following types of support

Armhf

S390x (IBM Z)

Ppc64le (IBM Power)

Devops@ubuntu:~$ uname-mx86_64devops@ubuntu:~$
