Creating a Stack with Docker Compose
After a few months of debate, we’ve decided to set up a cooking blog. After researching different platforms, we've chosen Wordpress with MySQL. We have a swarm cluster already set up where we host customer sites. To make maintaining Wordpress easier, we’ve decided to set it up as a stack. We'll need to create the Docker Compose file, deploy the stack, and finish the Wordpress setup.
