How to scan cluster and code for changes due to flux upgrade

[kondil]

Hey guys,

sorry for my newbie question ... I just don't know what to search and how to search for it ...

Scenario

I have a cluster running flux v2.3.0.

I want to upgrade flux to v2.4.0

Questions

1. Is there a flux way to scan my cluster for what is changing between the 2 versions?
2. Is there a flux way to scan my code/repos for what is changing between the 2 versions?

Clarifications

Right now I will read the CHANGELOG, create a small script that will grep the code/repos or fetch all objects' configuration from my cluster and grep for the required changes.

What I am looking for is whether flux provides a more elegant, out of the box functionality to achieve this.

If this is documented already, the link to it would be very much appreciated.

We have a GitHub Action that will open a PR when there is a new Flux version available: https://fluxcd.io/flux/flux-gh-action/#automate-flux-updates

Hey @stefanprodan,

thank you for this. I have been checking this already for automating our flux upgrade procedure.

However what I am asking above is how can I scan my cluster's components manifests for required changes according to the upcoming flux upgrade.

For example, in flux v2.4.0 the Bucket kind was promoted from v1beta2 to v1 (GA).

So what I am looking for is something that I can run against my yaml manifests or my cluster and for any bucket object not in v1 to throw me some notification.

Not sure if such thing exists already or if I am asking for something not available.
