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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# ECS DevOps — Deployment Strategies and CI/CD Advisory guidance for shipping software to Amazon ECS safely: choosing a deployment strategy (rolling, native blue/green, linear, canary), configuring failure detection and rollback (circuit breaker, CloudWatch alarms, one-click rollback), and wiring CI/CD pipelines (CodePipeline, GitHub Actions, ECR scanning). Every capability is scoped by launch type — EC2, Fargate, ECS Managed Instances, and ECS Anywhere (EXTERNAL) — because the strategy menu is not the same on each. > **The accuracy bar (non-negotiable for this skill).** ECS deployment capabilities changed rapidly between mid-2025 and mid-2026 (native blue/green Jul 2025, linear/canary Oct 2025, NLB for linear/canary Feb 2026, pause/continue May 2026, configurable circuit breaker Jul 2026). Never state a strategy/load-balancer/launch-type support combination you cannot cite to an AWS-published source — stale claims in this domain are usually *plausible but wrong*. When in doubt, defer to the live [ECS service deployment options page](https://docs.aws.amazon.com/AmazonECS/latest/developerguide/ecs_service-options.html). ## When to Use This Skill …

How to install
mdr add aws-samples/sample-apex-skills/ecs-devops@sha256:e209ea729ece73e6The line at the top of this page pins the label git:20260710.98b9c32, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
