Hi Tony,

at the moment: deploy == reconfigure Except for the special cases of Bifrost and Swift. If it ever changes, you will read about it in the release notes.

Hi,

What's the difference between deploy and reconfigure? I checked some roles, reconfigure.yml just include_tasks deploy.yml. And I didn't find reconfigure as a condition for any tasks or handlers. I checked kolla-ansible script, the difference is ANSIBLE_SERIAL is specified by reconfigure. I also see comment saying "Serial is not recommended and disabled by default.".

Here are some cases. I'd like to know which should be used.

#1 Add compute. After updating inventory with the new compute node, "deploy --limit new-compute" and "reconfigure --limit new-compute", do they have the same result? If not, what's the difference?

#2 Change configuration. In case configuration is changed in global.yml or inventory, which of "deploy" or "reconfigure" should be executed to update the cluster? Same or any difference?

#3 Fix the cluster I was told to rerun playbook to fix some problems, like a container was deleted. "deploy --limit host" or "reconfigure --limit host"? Same or any difference?

Thanks! Tony
