Creating the Task Definition

This article will be referencing the following repositories as the Docker image codebase:

In ECS, create a new Task Definition and choose the desired launch type compatibility (Fargate or EC2)

Attach the Task Role

Attach the task role created from Storing Secrets in Amazon Parameter Store to use in ECS.

Attach the Task Execution Role

This role is required by tasks to pull container images and publish container logs to Amazon CloudWatch on your behalf. You can use the default one created by Amazon.

Adjust the Task Size

We can assign total memory and CPU to the task. For PeerID, choose:

  • 2GB Task Memory (GB)

  • 1 vCPU Task CPU (vCPU)

Adding the Containers

Create two containers:

  • PeerID Backend

  • PeerID Frontend + Webserver (we will be using NGINX)

PeerID Backend

  1. Enter the container name.

  2. Enter the path to the Docker registry with the container Image.

  3. Enter 1024 for a soft limit for the memory.

  4. Enter 3000 tcp for the port mappings.

  5. Enter 756 CPU units.

  6. Tick the essential box.

  7. Enter /peerid-backend/docker-entrypoint.sh for the entry point.

  8. Enter npm,run,start for the command.

  9. Enter peerid-backend for the working directory.

  10. Enter the environment variables for PeerID Backend using ValueFrom and referencing the parameters from Systems Manager Parameter Store.
