Docker-compose is an orchestration mirror, so can docker-compose do what Dockerfile can do?
Docker-compose, as I understand it, is a container choreographer. For example, you have a php image, a mysql image, and a nginx image. If there is no docker-compose, then every time you start, you need to knock on the startup parameters of each container, environment variables, container naming, specifying the link parameters of different containers, etc. A series of operations are quite tedious. After using the docker-composer, you can write these commands in the docker-composer.yml file at one time. After that, every time you start the whole environment (including 3 containers), you just need to type a docker-composer up command to be ok.
The role of dockerfile is to build a mirror image from scratch.
The two are completely different things.
