it is OpenStack Containers service. It aims to provide an API service for running application containers without need to manage servers or clusters. and Zun is for users who want to treat containers as OpenStack-managed resource

Obviously it wasn't written yet at Pike. I have the feeling, though, that there is only one guide, no matter what release. So, the Queens guide might work for Pike as well. You could contact the author ( to confirm.

I am sorry for the missing of installation guide for Pike. The reason is simply because we wrote installation guide starting from Queens and maintain the guide afterward. Backporting the installation guide to Pike is on our TODO list but it might not happen right away. You could refer Queen's version of installation guide [1] as a reference with the following modifications:

  • Clone Kuryr-libnetwork 0.2.0 instead of stable/queens
  • Install python-zunclient 0.4.0 instead of 1.1.0

There could be other pitfalls and you are welcome to contact the Zun team if you find any issue. We provide community support in the following ways (of course, you are welcome to continue to use AskOpenStack for support and I will try to monitor the questions here):
