Getting console output from a Docker container

docker logs <container id> will show you all the output of the container run. If you're running it on ECS, you'll probably need to set DOCKER_HOST=tcp://ip:port for the host that ran the container.

To view the logs of a Docker container in real time, use the following command:

docker logs -f <CONTAINER>

The -f or --follow option will show live log output. Also if the container is stopped it will fetch its logs.
