  • Cardano-node release 10.1.2 was deployed to all environments

  • Dbsync release 13.6.0.1 was deployed to all environments

  • Just recipe query-gov-action-status was added to aid in live voting analysis of governance actions

  • The mainnet bootstrap cluster was scaled temporarily to accommodate a significant increase in client load which developed during the past week

  • With scheduled end of year vacation time and holidays starting, the cadence of work is expected to slow a bit in the following few node SRE updates

High level summary​

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

Some notable recent changes, updates or improvements include:

  • All environments have been upgraded to cardano-node 9.2.1.

  • Cardano-faucet 9.2 is available and deployed which is compatible with node 9.2.x and has fixed ipv6 functionality.

  • All deployed machines now default to nix 2.24-maint after an upstream bug causing a hash miscalculation in submodules has been fixed. Nix 2.21 forward required some rework of the colmena deployment recipes as dirty git trees now force an impure colmena deployment.

  • To ease the process of upgrading cardano-parts, releases will now be made instead of only PR merges with migration notes.

Repository Work​

Cardano-faucet​

  • Binds ipv6 interface in addition to ipv4, parses and logs all ips to a unified ipv6 format and applies hlint and fmt updates. cardano-faucet-pull-14

  • Makes required changes for cardano-api 9.2.0.0 and 9.3.0.0, removes void type sig constraints, bumps haskellNix, CHaP, cardano-api -> 9.3.0.0 for node 9.2.x compatibility. Disables mingw32 builds until alex in current haskellNix pin is updated. cardano-faucet-pull-15

Cardano-parts​
