High level summary​

The SRE team continues work on cardano environment improvements and general environment maintenance.

Some notable recent changes, updates or improvements include:

  • Cardano-node 8.9.1 is now deployed to all environments.

  • The legacy IOG mainnet metadata server has been retired with CF now providing metadata server services going forward.

  • Cardano-parts PR#35, merged and linked below, offers ip information integration into nixosConfiguration modules as well as template-diff and template-patch recipes for easier upgrades going forward.

Lower level summary​

Capkgs​

  • Adds a shortRev suffix to package names, fixes an rclone recipe, fixes a CI push action, defaults to recursively dereferenced object hashes, cleans up reference patterns. See the PR description for more details: capkgs-pull-2

High level summary​

The SRE team continues work on cardano environment improvements and general environment maintenance.

Some notable recent changes, updates or improvements include:

  • Cardano-node 8.8.1-pre is now deployed to sanchonet, two-thirds of preprod, one-third of preview and also voltaire private chain networks.

  • Catalyst Voltaire private chain was respun and an updated db-sync and govtool backend deployed after hard fork to Conway era.

  • IOG sanchonet pool block producers are now also signing mithril certificates.

  • A mithril-signer-verifier service now runs on all IOG SRE mithril signers and generates alerts if no recent mithril certificates have been signed.

  • All cardano-parts mithril clients, whether via nixosConfiguration, process-compose jobs or the nix cardano-node entrypoint, will now automatically verify that a trusted IOG pool has signed a mithril certificate prior to using the associated mithril state. If no trusted IOG pool has signed a recent mithril certificate, mithril state usage with be skipped and a classic sync from genesis to tip will be performed.

  • A significant amount of effort was applied towards the upcoming cardano-node 8.9.x-pre release in order to align nixos service module code between cardano-node nixos services, iohk-nix topology generation, cardano-ops legacy code, and cardano-parts module compatibility.
