With our basic configuration in place, we can now issue commands to Docker to build and start up our services. If the system we built was using only Dockerfile, this could be done without Compose, using direct docker engine commands. However, in a Compose setup there is a special docker-compose wrapper command that makes it easier to coordinate multiple interconnected containers.
The first step is to build our containers, as defined by the docker-compose.yml file. The first time that you build, any images used as starting points need to be loaded locally, and then each instruction in the Dockerfile is performed sequentially within the resultant machine:
myproject_docker/$ docker-compose builddb uses an image, skippingBuilding ...
