Building and pushing an application
We can also use the docker-compose build command to just build the images of an application defined in the underlying compose file.

image: fundamentalsofdocker/ch08-web:1.0
ports:

db:
build: database
image: fundamentalsofdocker/ch08-db:1.0
volumes:
- pets-data:/var/lib/postgresql/data
volumes:

Let's use that file now:
$ docker-compose -f docker-compose.dev.yml buildThe -f parameter will tell the Docker Compose application which compose file to use.
To push all images to Docker Hub, we can...
