Let's start with creating the infrastructure services first:
mongodb: image: planets/mongodb ports: - "27017"
server: image: planets/server ports: - "8080" links: - mongodb environment: - SPRING_PROFILES_ACTIVE=prd homepage: image: planets/homepage ports: - "28080:8080" links: - server environment: - SPRING_PROFILES_ACTIVE=prd
The ports decleration of the service homepage is a bit different (
28080:8080) which means the WWW port is exposed to the outside world as
28080. In the previous examples the port was only available to other containers using a link.
Change into the directory that contains your
docker-compose.yml and fire up the application with a single command:
$ docker-compose up
Update the whole application:
$ docker-compose stop -t 30 $ docker-compose pull $ docker-compose up -t 30 -d
Nice addition in the Docker universe...
Per default the containers are prefixed with the directory name where the Docker compose file is located.
If you want to change the prefix you can add
-p <prefix> to your compose commands.
