Setup

1. cd <your-project-directory>
2. Copy docker-compose.yml to your project directory.
3. Create directory
   $ mkdir html nginx at the same level of docker-compose.yml
4. Copy default.conf and nginx.conf to <your-project-directory>/nginx/

Your project structure should be look like this:

<your-project-directory>
-- docker-compose.yml
-- html
-- nginx
---- default.conf
---- nginx.conf

Run Docker

1. Make sure your machine has already install Docker
2. For Docker Compose run command: $ docker-compose up -d (for daemon mode) or docker-compose up.
3. For Docker Swarm run command: $ docker stack deploy -c docker-compose.yml <project-name>
