Mimir-to-grafana cloud testing

[Rotfuks]

Motivation

In order to raise our confidence in the stability of our observability platform and be sure that our ongoing work and releases won't negatively impact our observability platform operations we need to create extensive tests giving us early feedback loops.

Todo

• Investigate some good initial test cases to give us feedback on the stability of a release on mimir on CI. This can be:
  • Validate Helm chart templating
  • Deploy chart on Kind (single instance)
• Implement those CI test cases

Outcome

• We have early, automatic feedback about the impact of a release of the mimir-to-grafana-cloud prometheus before releasing.

After LOTS of efforts and changes, the chart testing pipeline is now working for this app 🥳
