Quicker way to update container when changing Dockerfile

Question

I am new to Docker and the process I use to create and execute a container from a Dockerfile is the following:

1. docker build -t (IMAGE_NAME) .
2. docker docker run -itd --name (CONTAINER_NAME) (IMAGE_NAME)
3. docker exec -it (CONTAINER_NAME) bash

However, if I want to update my Dockerfile and run the container again I have to do the following:

1. docker ps to get the ID of my container
2. docker container stop (ID)
3. docker rm (ID)

and then I have to repeat the first three steps. Is there a quicker way to do this or have to rerun these steps every time I update my Dockerfile? This is very tedious

Answer 1

If time is a concern, enable Buildkit, it is way faster to build.

export DOCKER_BUILDKIT=1

You already figured out to use name on all 3 commands, you can combine all 3 commands

docker rm NAME; docker build -t NAME /absolutepath && docker docker run -itd --name NAME && docker exec -it NAME bash

I use && (run next command when return code is 0=no error) on the execution commands and ; (continue to next command, even on error e.g 'container not found') on the initial removal of the previous container. Since this won't stop the chain in case you forgot you already removed the container. As you also see I encourage you to use absolute path for docker build so it works in any directory, should you happen to move around slightly.
