Tested Runtimes for 2023.1

At the start of the 2023.1 development cycle, the current LTS or stable distribution <pti-linux-distros> versions are:

  • Ubuntu 22.04
  • Debian 11

Additional testing for smooth upgrade

In this release, we are adding the testing of Ubuntu new version 22.04. For smooth upgrade, we will continue the minimum testing for previously supported Ubuntu version in this release.

  • Ubuntu 20.04

Best Effort

This distribution list is the best effort to test them in OpenStack CI/CD. These may not be part of integrated testing and may be tested periodically only.

  • CentOS Stream 9

Python Runtimes for 2023.1

It is the policy <../../resolutions/20181024-python-update-process> 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 3.8 (available as default in Ubuntu 20.04)
  • Python 3.10 (available as default in Ubuntu 22.04)

Other than the above Python versions, Debian 11 has Python 3.9 as default which we are not suggesting to run unit tests. We assume that anything that works on Python 3.8 and 3.10 will also work on 3.9.

More details on Python requirements can be found in pti-python.

Node.js Runtime for 2023.1

Based on the available and supported versions of Node.js (in either our LTS or stable distributions <pti-linux-distros> or in external source) all JavaScript testing should target:

  • Node.js 18

More details on Javascript requirements can be found in pti-javascript.

Golang Runtime for 2023.1

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.

More details on Go requirements can be found in pti-golang.
