Hi Havi! Interesting experiment on ECS! I actually used to do this all the time back on my previous employer. I go on to do the command docker exec -it /bin/bash so I can enter the bash shell of my containers. I did this so I can gain console access to the task so I can run rails console on them and do my data requests.
