Running the X-Ray Daemon on Amazon ECS

On Amazon ECS, create a Docker image that runs the daemon, upload it to a Docker image repository, and then deploy it to your Amazon ECS cluster.

Use an instance profile to grant the daemon permission to upload trace data to X-Ray. For more information, see Giving the Daemon Permission to Send Data to X-Ray.

Example Dockerfile

Add the following lines to your Dockerfile file to copy and run the daemon.

FROM amazonlinux COPY xray /usr/bin/xray ENTRYPOINT ["/usr/bin/xray", "log-file /var/log/xray-daemon.log"]

Download the X-Ray daemon Linux executable into the same folder as your Dockerfile and build it to create an image.

$ wget $ unzip $ docker build

To run the daemon in its own container, you need to change the address on which the daemon runs to make it routable from other containers. Use the --bind option to run the daemon on instead of localhost.

Example Dockerfile - Ubuntu

This Dockerfile file runs the daemon in its own container. It downloads the Debian installer from Amazon S3 and installs it with dpkg. For Debian derivatives, you also need to install certificate authority (CA) certificates to avoid issues when downloading the installer.

FROM ubuntu:16.04 # Install CA certificates RUN apt-get update && apt-get install -y --force-yes --no-install-recommends apt-transport-https curl ca-certificates wget && apt-get clean && apt-get autoremove && rm -rf /var/lib/apt/lists/* RUN wget RUN dpkg -i aws-xray-daemon-2.x.deb # Run the X-Ray daemon CMD ["/usr/bin/xray", "--bind="]
