eirinix - Writing Extensions for Eirini
summary
eirinix is a Go module that builds Kubernetes mutating admission webhooks, generates webhook YAML and certificates, and runs an HTTP server to intercept CF push pod creation and return JSON patch sets (the diff) to mutate pods. Implementations include a Percy broker that creates and reuses PVC-based persistence across apps, a kube-native logging component that uses API watchers instead of a Fluentd daemonset, and SSH support that generates keys as Kubernetes secrets and mutates pods to consume them; all work without changing Eirini core.
