+```
+The compose file defines an application with four services `redis`, `nginx`, `web1` and `web2`.
+When deploying the application, docker-compose maps port 80 of the nginx service container to port 80 of the host as specified in the file.
+
+
+> ℹ️ **_INFO_**  
+> Redis runs on port 6379 by default. Make sure port 6379 on the host is not being used by another container, otherwise the port should be changed.

+
+## Expected result
+
+Listing containers must show three containers running and the port mapping as below:
+
+
+```
+docker-compose ps
+```
+
+## Testing the app
+
+After the application starts, navigate to `http://localhost:80` in your web browser or run:
+
+```
+curl localhost:80
+curl localhost:80
+web1: Total number of visits is: 1
+```
+
+```
+curl localhost:80
+web1: Total number of visits is: 2
+```
+```
+$ curl localhost:80
+web2: Total number of visits is: 3
+```
+
+
+
+## Stop and remove the containers
+
+```
+$ docker-compose down
+```
+
