Webhooks for Automated Updates [B]
summary
A microservice uses Docker Hub automated builds and Docker Hub webhooks to detect new image tags (reads push_data.tag and repository.repo_name), then issues a patch Deployment via Kubernetes API to change the image. Implementation is in Go inside Rancher’s webhook framework, runs in-cluster, and uses rolling updates (replicas 3, maxUnavailable 1, maxSurge 1). Demo shows a git push triggers a build, webhook, rolling update and the app updates with zero downtime.
