+## Compose sample application: ASP.NET with MS SQL server database
+
+Project structure:
+```

+├── app
+│   ├── aspnetapp

+services:
+  web:
+    build: app
+    ports:
+    - 80:80
+  db:
+    image: microsoft/mssql-server-linux
+    ...
+```
+The compose file defines an application with two services `web` and `db`. The image for the web service is built with the Dockerfile inside the `app` directory (build parameter).
+
+When deploying the application, docker-compose maps the container port 80 to port 80 of the host as specified in the file.
+Make sure port 80 on the host is not being used by another container, otherwise the port should be changed.
+
+
+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating network "aspnet-mssql_default" with the default driver

+## 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

+```
+
+After the application starts, navigate to `http://localhost:80` in your web browser.
