Main achievements​

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

  • All cardano release environments, including preview, preprod, mainnet legacy and mainnet new clusters were upgraded through various cardano-node releases of 8.9.2, 8.9.3, 8.9.4, 8.12.1, and finally into 8.12.2 by the end of June

  • Cardano pre-release environments additionally iterated through pre-release upgrades of 8.11.0-pre, 8.12.0-pre, and finally into 8.12.2 by the end of June with the exception of sanchonet which remains pinned at 8.11.0-pre until the next respin to support node version 9.0.0 or greater

  • Sanchonet environment was re-spun two times for pre-release Conway testing of cardano-node versions 8.10.0-pre and 8.11.0-pre respectively

  • Private chain environment was re-spun three times to support fast epoch Conway testing

  • Cardano-playground and cardano-mainnet repos have added ten operations oriented documents for knowledge transfer

  • Block producers which participate in mithril signing will now produce metrics and can have them scraped with the default metrics agent

  • A cluster spin-up job to utilize the new cardano-cli create-testnet-data sub-command was created

  • A nixosModule, dashboards and alerts were added supporting the new cardano tracing system

  • Many new operations scripts and features were added, including a template diff and patch recipe to pull the latest cardano-parts improvements to consuming repositories more easily

Next steps​

  • Finalize support for the new cardano-node tracing system once the service is rewritten for general consumption

  • Add IPv6 cardano-parts support

  • Extend govtool frontend and backend to a process-compose stack once govtool is publicly buildable again

  • Continue cardano-parts and operations improvements
