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. -yoctozepto On Sun, Sep 6, 2020 at 2:13 AM Tony Liu <tonyliu0592@hotmail.com> wrote:

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
