Main achievements

In addition to ongoing general maintenance and support of cardano environments, some highlights of SRE achievements for this quarter include:

  • Cardano-parts started offering regular releases to ease the process of upgrading rather than only PR merges with migration notes.

  • All IOE cardano-parts supported node environments, including preview, preprod, sanchonet, mainnet were upgraded through various cardano-node releases including 10.0.0-pre, 10.1.0-pre, 10.1.1, 10.1.2, and finally into 10.1.3 by the end of December.

  • All environments were migrated from deprecated grafana agent to grafana alloy.

  • Sanchonet environment was re-spun twice; once for cardano-node 10.0.0-pre and once for a community scheduled PV11 hardfork test.

  • Preview and preprod networks were successfully forked into Conway era, Plomin protocol version 10.0.

  • Private and shelley-qa chains were retired after fulfilling their intended goal.

  • Remaining cardano-world legacy resources were retired, replaced by cardano-playground.

Details of this and other SRE work can be found in the biweekly SRE reports.

Next steps

  • Switch to the new cardano-node tracing system as default and retire use of the legacy tracing system, including dashboards, alerts, cardano-tracer and cardano-node nixos service updates as well as container image required changes.

  • Continue cardano-parts and operations improvements.
