Changes to our base job nodeset and Ansible 5 removal
by Clark Boylan 12 Oct '22

12 Oct '22

As mentioned in the previous email [0] about updating our default Ansible version to Ansible 6, Zuul will be removing support for Ansible 5 soon. Based on Zuul's currently estimated release schedule we expect this to happen on or near October 18. This change won't take effect until OpenDev restarts Zuul. We will try to make that happen quickly after Zuul lands this change in order to catch any issues quickly. Additionally, it has been called out that we are still defaulting our base job nodeset to ubuntu-focal. Ubuntu Jammy has been released for about 6 months now and has a .1 release as well. To catch up we will update the default nodeset in our base jobs to ubuntu-jammy on October 25, 2022. If you would like to test that your jobs run against Ubuntu Jammy you can modify your jobs to set `nodeset: ubuntu-jammy` today and test them. Note, any jobs that expect a specific platform should already be explicitly setting the nodeset they rely on. There are a number of jobs already running on Jammy which gives us confidence in the newer images. [0] https://lists.opendev.org/pipermail/service-announce/2022-October/000046.ht… Clark

Updating Zuul tenants' default-ansible-version to 6
by Clark Boylan 06 Oct '22

06 Oct '22

Hello, The OpenDev team is planning to update the default-ansible-version to 6 in the near future. Zuul is planning to drop support for Ansible 5, and switching OpenDev to Ansible 6 early allows us to provide valuable feedback if there are problems. There are other reasons for the switch as well. Ansible 5 broke pipelining, but we expect Ansible 6 to correct this problem. Having pipelining should improve the runtime of jobs. We had been holding off on making this change as StarlingX and OpenStack have both recently worked through some fairly major releases. Those releases exist now making this a good time for a change like this. As far as testing goes, Zuul's Zuul tenant has been running with an Ansible 6 default for several weeks now. I've also tested this change with Devstack specifically [0] as Devstack seems to have a good representative set of complicated jobs. The change to update our defaults is up for review [1]. Feel free to leave any comments there or on this email thread. Note that you can override this change if necessary using the same mechanism I used to test Devstack [0]. However, if you do this please communicate that change to us as Zuul does plan to remove Ansible 5 support which means any problems with Ansible 6 need to be communicated back to Zuul.
