+## Compose sample application
+### Elixir application with Phoenix framework and a Postgres database
+
+Project structure:
+```
+.
+├── app
+│ ├── Dockerfile
+│ ...
+├── docker-compose.yaml
+├── phoenix_output.png
+└── README.md
+```
+
+[_docker-compose.yaml_](docker-compose.yaml)
+```
+services:
+ app:
+ build: app
+ environment:
+ ...
+ db:
+ image: postgres
+ ports:
+ - "5432:5432"
+ environment:
+ ...
+```
+The compose file defines an application with three services `app` and `db`.
+When deploying the application, docker-compose maps the port 4000 of the app container to port 4000 of the host as specified in the file.
+Make sure port 4000 on the host is not already being in use.
+
+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating network "phoenix-postgres_default" with the default driver
+Creating volume "phoenix-postgres_postgres" with default driver
+...
+Successfully built faa13730018d
+Successfully tagged phoenix-postgres_app:latest
+Image for service app was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
+Creating phoenix-postgres_db_1 ... done
+Creating phoenix-postgres_app_1 ... done
+```
+
+## Expected result
+
+Listing containers must show two containers running and the port mapping as below:
+```
+$ docker ps
+CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
+a12ab4dc42fb phoenix-postgres_app "sh entrypoint.sh" 22 seconds ago Up 20 seconds 0.0.0.0:4000->4000/tcp phoenix-postgres_app_1
+39c7a3212d51 postgres "docker-entrypoint.s…" 23 seconds ago Up 21 seconds 5432/tcp phoenix-postgres_db_1
+```
+
+After the application starts, navigate to `http://localhost:4000` in your web browser:
+
+
+
+Stop and remove the containers
+```
+$ docker-compose down
+Stopping phoenix-postgres_app_1 ... done
+Stopping phoenix-postgres_db_1 ... done
+Removing network phoenix-postgres_default

+
+To start your Phoenix server:
+
+ * Install dependencies with `mix deps.get`
+ * Create and migrate your database with `mix ecto.setup`
+ * Install Node.js dependencies with `cd assets && npm install`
+ * Start Phoenix endpoint with `mix phx.server`
+
+Now you can visit [`localhost:4000`](http://localhost:4000) from your browser.
+
+Ready to run in production? Please [check our deployment guides](https://hexdocs.pm/phoenix/deployment.html).
