Introducing OCI Webhook Support in Argo CD: From Polling To Real-Time
summary
Argo CD adds webhook support for OCI registries so published OCI artifacts trigger near‑real‑time reconciliation instead of waiting the default ~120s+60s jitter polling cycle (about 3 minutes). Current implementation supports GHCR with package and newer registry_package events, uses a shared webhook secret, and accepts retried deliveries (demo uses ngrok for a public endpoint). Docker Hub, ECR and JFrog integrations are planned. GitHub can introduce >5 minute delivery latency; fallback to periodic polling or manual refresh remains if webhooks fail.
