  • Upgrade Loki from 2.5.0 to 2.6.1
  • ⚠️ Major upgrade, breaking changes
    • PVCs change as we switch from distributed (ingester, compactor, distributor...) to simple-scalable (just read and write pods)

Fixed

  • Azure sample config file: storage setup
  • Sample config files: placement for compactor

0.4.3 - 2022-07-06

Fixed

  • from giantswarm/grafana-helm-charts-upstream: values schema accepts strings in all default-null fields, like "fullnameOverride"

  • Upgrade upstream chart from 0.48.5 to 0.49.0

Fixed

Changed

  • Upgrade upstream chart from 0.33.0 to 0.48.5
  • Upgrade Loki from 2.2.1 to 2.5.0
  • Breaking: Upgrade requires manual intervention.

Changes required in your values.yaml file:

  • now ruler, distributor and queryFrontend require access to the object storage.
  • storage config is more similar to loki config file, and is done on loki.schemaConfig and loki.storageConfig.
  • data format has not changed, so as long as you keep the same schema version and storage setup, you can upgrade/rollback with no data loss.
  • feel free to ask us if you need help regarding your specific setup.

### Upgrade procedure

  1. create your updated values.yaml file.
  2. in happa, update loki version.
  3. in happa, replace values with your updated values.yaml file.

Notes:

  • during upgrade, log histogram can be inconsistent. This only impacts log histogram, and only during upgrade.
  • In case of rollback, logs times may be wrong because latest loki version adjusts timestamps.
