How to combine docker build and docker run into one command

Question

There is a Dockerfile in the current directory. Initially we could:

1. docker build to build the image
2. make use of the built image to docker run to start the corresponding docker container

But often times there is need to update the Dockerfile. As a result, there would be the following steps to restart the docker container with the latest update

1. docker build to build the image again
2. kill/stop the running docker container
3. remove the image
4. docker run to start the docker container again with the updated docker image

But there are 4 steps involved =>

Question: How to minimize the 4 steps above, e.g. rebuild the docker image and restart the updated container in one go like the docker-compose up --build <sevice_name>

Answer 1

I've made a simple script that will trigger an action once a watched file get modified.

The answer can be found here.

What you can do in this case, is simply write a small bash script with the 4 steps needed. and add it to be executed to the script whenever the dockerfile change occurs.

An alternative solution to reduce this commands series, docker-compse can be a good option as the docker-compose down command will stop containers and removes containers, networks, volumes, and images created by the docker-compose up command.

Lastley, as suggested in the comments, You can use makefile which defines a set of commands to run and the make utility runs them.
