Tested Runtimes for Yoga

At the start of the Yoga development cycle, the current LTS or stable distribution versions are:

  • Ubuntu 20.04

  • CentOS Stream 8

  • CentOS Stream 9

  • Debian 11

Python Runtimes for Yoga

It is the policy that each OpenStack release cycle will target the latest available version of Python; default Python runtimes on the distributions listed above; and versions used in integration tests at the start of the cycle, at least until the point when all projects have migrated to a later version.

Based on the criteria above, all Python-based projects must target and test against, at a minimum:

  • Python 3.6 (available as default in CentOS Stream 8)

  • Python 3.9 (available as default in Debian 11 and CentOS Stream 9)

Other than the above Python versions, Ubuntu 20.04 has Python 3.8 as default which we are not suggesting to run unit tests. We assume that anything that works on Python 3.6 and 3.9 will also work on 3.8. Do note, however, Ubuntu is our primary target and thus the majority of tempest jobs run with it and its Python 3.8 anyway.

Node.js Runtime for Yoga

Based on the available versions of Node.js supported in our LTS or stable distributions all JavaScript testing should target:

  • Node.js 14

More details on Javascript requirements can be found in Project Testing Interface: JavaScript.

Golang Runtime for Yoga

At this time, there are still frequent releases of Go with a wide variety of distribution packaged versions. Given the current state of Go support and the number of projects within OpenStack using Go, no formal version declaration is being made at this time.
