ECS Service Deploy Error: ECS Deployment Circuit Breaker was triggered


Hi AWS, I am creating an ECS Service and while doing that I am getting the error: Resource handler returned message: "Error occurred during operation 'ECS Deployment Circuit Breaker was triggered'." (RequestToken: 8d5f80cb-c2d8-e7fc-ff9e-1d221362973b, HandlerErrorCode: GeneralServiceException) as attached in the screenshot below.

I have checked the error logs in CloudWatch Log Group as well but didn't find any and I am attaching the screenshot below for the same.

ECS Service CloudWatch Log Group

I have checked the Dockerfile and tried to create a docker image locally and it worked fine but just pasting the code to review it once if there is any error:

FROM --platform=linux/amd64 node:18-alpine
COPY . .
RUN yarn install
CMD ["node", "index.js"]

I have also followed the repost link, but no luck.

Please advise.

Hello Arjun,

Here issue shows "ECS Deployment Circuit Breaker was triggered" indicates ECS stopped deploying your service due to repeated failures.

  • Check ECS cluster and task logs, not just CloudWatch logs, for detailed failure messages.

  • Verify your container has a health check defined to avoid triggering failures.

Check Port Mappings: Ensure your container port matches your application port (e.g., if your app runs on port 3000, set containerPort and hostPort to 3000 in the task definition).

Verify Logs: Review ECS task and container logs in CloudWatch for errors.

Increase Resources: Ensure the CPU and memory settings in the task definition are sufficient for your application.

Network Configurations: Check VPC, subnets, and security groups to ensure proper network configurations.

Edit the Container Definition

  • In the "Container Definitions" section, click "Edit" next to the container you want to modify.

  • Scroll down to the "Port mappings" section.

Example of corrected port mappings in your task definition:

"portMappings": [
        "containerPort": 3000,
        "hostPort": 3000,
        "protocol": "tcp"
