• YOU CAN USER JUST A PORTION OF THE CONTAINERID ON STOP AND REMOVE

• ENTRYPOINT: Same as CMD except it can’t be overridden

• Connect to a running container: docker exec -it [containerid] <cmd>

• Delete a local docker image

docker rmi [image ID] or docker rmi [repo:tag]

• Docker Volumes

• docker push didn’t work the first time, this link was helpful. Ended up needing to run:

docker login

prior to my push
