High level summary​

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

Some notable recent changes, updates or improvements include:

  • IOE participated in a community driven Sanchonet network chain disaster recovery test event to purposely break Sanchonet and recover by mechanisms and tools discussed in CIP-0135 including db-truncater and db-synthesizer.

  • Faster test deployment iteration of a 10.6.0 pre-release candidate is underway to some preview and preprod testnet machine deployments with a tight feedback loop between SRE and dev team for observations and debugging when issues are found.

  • A new cardano-tracer OCI container will be provided with the upcoming 10.6.0 pre-release now that the new tracing system will be default.

  • SRE team facilitated the passage of a governance action on the preview network, soon to be submitted to preprod and likely followed by a mainnet proposal and full community vote.

  • SRE team has begun providing some additional support to the Midnight Scavenger Mine project as needed until the Scavenger Mine phase completes.

  • This PR includes various SRE related changes for 10.6.0 pre-release readiness:

    • Bumps iohk-nix for config updates from iohk-nix PR#602
    • Fixes configuration change related CI checks.
    • Merges bp and non-bp configurations into a single config whereby ouroboros-network now automatically determines PeerSharing and Target* parameters which previously required being explicitly declared.
    • The new tracing system is now set as the default configuration; the legacy tracing system config is still made available.
    • The mainnet default topology configuration now includes a peerSnapshot declaration for making testing of GenesisMode more convenient.
    • Adjusts OCI containers for the new config setups and also includes peer-sharing configs for each network
    • Updates the nixos cardano-node service for the deprecation of useNewTopology given P2P is now the only networking mode as of 10.6.0.
    • Updates the nixos cardano-node service for new tracerSocketNetworkAccept and tracerSocketNetworkConnect cardano-tracer connection options.
    • Updates the nixos cardano-node service to support SRV peer records.
    • Updates the nixos cardano-tracer service for option name changes of acceptingSocket to acceptAt and connectingToSocket to connectTo; related workbench services were also updated accordingly.
    • For the binary releases, the cardano-submit-api config and peer-sharing config was added.
    • The default cardano-submit-api config was made compatible with the new tracing system.
