rails_pod_kit

https://github.com/fabn/rails_pod_kit

Packages the yabeda ecosystem and health-monitor-rails into a single, opinionated kit for running Rails applications on Kubernetes: Puma, Sidekiq and SolidQueue runtime metrics in Prometheus text format on an in-process /metrics endpoint (default port 9394), plus a /healthz endpoint wired for liveness/readiness/startup probes. No sidecar, no separate collector. It also hosts the schedulers that let a job executor scale to zero without stranding its recurring jobs: a supervised SolidQueue scheduler thread, and a supervised sidekiq-cron poller for Sidekiq.
