- Plan and template management in git.
This could be an iterative step towards eliminating Swift in the
undercloud.
Swift seemed like a natural choice at the time because it was an existing
OpenStack service. However, I think git would do a better job at
tracking
history and comparing changes and is much more lightweight than Swift.
We've
been managing the config-download directory as a git repo, and I like
this
direction. For now, we are just putting the whole git repo in Swift, but
I
wonder if it makes sense to consider eliminating Swift entirely. We need
to
consider the scale of managing thousands of plans for separate edge
deployments.
I also think this would be a step towards undercloud simplification.
+1, we need to identify how much this affects the existing API and overall user
experience
for managing deployment plans. Currentl plan management options we support are:
- create plan from default files (/usr/share/tht...)
- create/update plan from local directory
- create/update plan by providing tarball
- create/update plan from remote git repository
Ian has been working on similar efforts towards performance improvements [2], It
would be good to take this a step further and evaluate possibility to eliminate
Swift entirely.

We need to do something about ironic-inspector then: it currently depends on
swift for storing collected data. Fortunately, there is a spec to fix it, but it
hasn't been our team's priority. Reviews are welcome:
