Hello, if you are working on a migration to Kolla, there is a nice guide written by StackHPC that provides one example approach for this complicated maneuver: https://www.stackhpc.com/migrating-to-kolla.html

Perhaps not relevant to your specific case, but it can offer some guidance!

Cheers,

Hi,

seems like someone else is trying to migrate an existing setup to kolla 😉

We currently try it step by step. 

1. Use kolla images instead of self developed builder.
2. Generate suitable kolla configuration file layout
3. Hopefully kolla-ansible will hand over

But we are still in PoC state.

Hi,

I wonder if it's supported by Kolla Ansible to deploy a specific
host and add it into existing cluster, like replace a control
host or compute host?


Thanks!
Tony
