Working with Docker-Compose

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a Compose file to configure your application’s services. Then, using a single command, you create and start all the services from your configuration.

MongoDB + NodeJS + CoffeeScript

With this example you will have a small CoffeeScript app running on Docker using a MongoDB database and a NodeJS web server in two separate containers, both deployed thanks to Docker-Compose.

First we build our containers, in this case we stared with NodeJS image pull from the registry with FROM directive, then MongoDB image called on docker-compose.yml file with image command.

Note: This image will be named dockercompose_web with a size of 649MB so be patient when building...

$ docker-compose build

Now let's run our two services together in an isolated environment.

$ docker-compose up

We now should be able to access the app locally at port 8080.

http://localhost:8080

The configuration used to build and run the container can be found in docker-compose.yml and Dockerfile.
