Hi,
At the recent kolla virtual PTG [1], we discussed the move to python 3 images in the Train cycle. hrw has started this effort for Ubuntu/Debian source images [2] and is making good progress.
Next we will need to consider CentOS and RHEL. It seems that for Train RDO will provide only python 3 packages with support for CentOS 8 [3]. There may be some overlap in the trunk (master) packages where there is support for both CentOS 7 and 8. We will therefore need to combine the switch to python 3 with a switch to a CentOS/RHEL 8 base image.
Some work was started during the Stein cycle to support RHEL 8 images with python 3 packages. There will no doubt be a few scripts that need updating to complete this work. We'll also need to test to ensure that both binary and source images work in this new world.
Tripleo team - what are your plans for CentOS/RHEL 8 and python 3 this cycle? Are you planning to continue the work started in kolla during the Stein release?
Thanks, Mark
