How to upgrade the Thanos Package chart📜
This chart is reconciled against the upstream chart as declared in the Kptfile.
When an upgrade is required, kpt can be ran to pull the updates with a targeted tag.
(from the repository root)
kpt pkg update chart@<new tag> --strategy alpha-git-patch
Once completed, you will need to reconcile the modifications that Big Bang makes.

Testing a new Thanos version📜
Because Thanos aggregates data, it makes sense to integrate Thanos with Prometheus, MiniIO, and Grafana. The cypress tests will verify datasources are enabled for the monitoring.prometheus-sidecar and an s3 objectstore datasource is registered. See the values.yaml and bigbang test-values.yaml for configuration settings.
When using the bigbang install (monitoring/grafana/thanos/and passing in test-values.yaml, you should be able to:
- Go to https://thanos.bigbang.dev
- Select “Stores” and verify you see the
SidecarandStorestores. These should both beUP. - Go to https://grafana.bigbang.dev/connections/datasources/edit/prometheus and verify the grafana datasource
