+Project structure:

+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating network "flask_default" with the default driver
+Building web
+Step 1/6 : FROM python:3.7-alpine

+
+## 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:5000` in your web browser or run:
+```
+$ curl localhost:5000
+Hello World!
+```
+
+Stop and remove the containers
+```
+$ docker-compose down
