+The compose file defines an application with one service `sparkjava`.
+When deploying the application, docker-compose maps port 8080 of the web service container to port 80 of the host as specified in the file.
+Make sure port 80 on the host is not already being in use.
+
+## Deploy with docker-compose
+
+```
+$ docker-compose up -d
+Creating network "vuejs_default" with the default driver
+Building web
+Step 1/8 : FROM node:10
+...
+Successfully tagged vuejs_web:latest
+WARNING: Image for service web was built because it did not already exist. To rebuild this image you must use `docker-compose build` or `docker-compose up --build`.
+Creating vuejs_web_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

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

+Stop and remove the containers

+$ docker-compose down
+Stopping vuejs_web_1 ... done
+Removing vuejs_web_1 ... done
