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.
Maybe beside of tracing logs is better idea to enter into container with:
docker exec -it CONTAINER_ID /bin/shand investigate your process from inside.
