📰 Dev.to · willamhou
Learn how to auto-update Kubernetes workloads using an annotation-driven rollout with a circuit breaker, ensuring seamless and reliable upgrades
Action Steps
- Configure a k8s4claw auto-update controller to poll OCI registries on a cron schedule
- Apply semver-filtered upgrades to a StatefulSet using a single annotation
- Verify the health of the updated workload and roll back automatically if issues arise
- Utilize Status fields to maintain durable state and track rollout progress
- Implement a circuit breaker to prevent cascading failures during rollout
