Part of #372

Same change for main here: #399

Tip

Once stackabletech/stackable-cockpit#440 is released, testing of this will be far more automated.

I realise it isn't clear as to why, but trust me bro.
tl;dr: Local mess becomes organised and committed.
Happy to discuss why if anyone is interested.

  • Tempo uses port 3200 for querying (eg: from Grafana) after a chart update.
  • Jaeger changed the name of the service.
  • My local testing (mess) deploys to a different namespace, and relies on OpenTelemetryCollector having FQDNs in their configs.
  • I also noticed a 0.0.0-dev reference didn't get picked up by the release script. See commit message for an idea.

Note

This PR has been tested.

Changed in chart 1.21.1:

> Breaking Change * In order to be consistent with other projects and documentations, the default port has been changed from 3100 to 3200.
…jaeger

It changed somewhere between chart 3.4.1 and 4.5.0 (massive restructure)
This allows otelcollector configs to be used by pods in any namespace and make it easier to use Secret Operator generated TLS certs so grafana can connect to datasources securely.
The script doesn't look for that pattern, so it was missed.

We should consider using renovate instead of a script with special (though fragile) rules.
