Question

What is the difference between docker-compose build and docker build?

Suppose in a dockerized project path there is a docker-compo

Answer 1

Basically, docker-compose is a better way to use docker than just a docker command.

If the question here is if docker-compose build command, will build a zip kind of thing containing multiple images, which otherwise would have been built separately with usual Dockerfile, then the thinking is wrong.

Docker-compose build, will build individual images, by going into individual service entry in docker-compose.yml.

With docker images, command, we can see all the individual images being saved as well.

The real magic is docker-compose up.

This one will basically create a network of interconnected containers, that can talk to each other with name of container similar to a hostname.
