ecs-devops

Use when someone is deploying, releasing, or shipping software to Amazon ECS — phrased as "blue/green deployment on ECS", "canary deployment for my ECS service", "set up CI/CD for ECS", "GitHub Actions deploy to Fargate", "my ECS deployment is stuck", "ECS deployment circuit breaker", "ECS task sets", or "migrate off CodeDeploy blue/green". Covers strategy selection (rolling/blue-green/linear/canary), lifecycle hooks, circuit-breaker and alarm rollback, and pipelines (CodePipeline, GitHub Actions, ECR scanning) — scoped per launch type (EC2, Fargate, Managed Instances, ECS Anywhere). Trigger even if "deployment strategy" is never said — any release-safety, traffic-shifting, rollback, or pipeline decision for an ECS service qualifies. Skip for EKS/Kubernetes (use eks-* skills) and greenfield ECS architecture with no release angle (use ecs-architect for design and ecs-build for Terraform generation incl. deployment config blocks). For ECS monitoring stacks use ecs-observability; for GPU/ML on ECS use ecs-genai.
