Running the X-Ray Daemon on Amazon ECS

On Amazon ECS, create a Docker image that runs the X-Ray daemon, upload it to a Docker image repository, and then deploy it to your Amazon ECS cluster. You can use
port mappings and network mode settings in your task definition file to allow your application to communicate with the daemon container.

To enable X-Ray tracing for an application deployed on an ECS cluster, you need to take the following steps:

Create a Docker image with the X-Ray daemon: You can create a custom Docker image that includes the X-Ray daemon. This image should be based on the official AWS X-Ray daemon image available on DockerHub. You can then use this image to run your application on ECS.
Attach an IAM role with permissions to the ECS Cluster: You need to attach an IAM role to the ECS cluster, which has permissions to communicate with the X-Ray service. This role should have the AWSXRayDaemonWriteAccess policy attached to it.
Deploy the EC2 Instance to the ECS Cluster: You need to deploy an EC2 instance to the ECS cluster, which will run the Docker container instances that host your application. This EC2 instance must have an IAM instance profile assigned to it that includes the IAM role with the AWSXRayDaemonWriteAccess policy.
Assign a role to the Docker container instance in ECS which has a policy that allows it to write to xray: When you create a task definition for your application in ECS, you can specify an IAM task role for the container instances. This role should include the AWSXRayWriteOnlyAccess policy, which grants the container instance permission to write data to X-Ray.

Therefore, the correct answers are A and D:

A. Create a Docker image with the X-Ray daemon. D. Assign a role to the Docker container instance in ECS which has a policy that allows it to write to xray.
