ZERO Hydra Failures

Hydra scaling

The activity during ZHF is usually higher, so more build capacity is a good investment, to keep up with the pace of contributions.

There is an autoscaler in place for aarch64-linux and x86_64-linux while the darwin allocations are pretty much static.

If capacity issues are apparent, contact the infrastructure team on the nixos-org-configurations repository (example: 21.11 example), and start a discussion in #infra:nixos.org.

ZHF issue

• Create an issue for tracking Zero Hydra Failures progress. ZHF is an effort to get build failures down to zero. Examples: 22.11, 22.05

• The nixpkgs/trunk jobset is ideal to track regressions, since it builds for all platforms.

• Subscribe to the issue and monitor the conversation for new blockers.

• Get in contact with the staging team through their Matrix room at #staging:nixos.org to coordinate the staging-next merges.
