Setup WordPress with Docker-Compose on CoreOS

Setup WordPress with Docker-Compose on CoreOS

Setup Steps

1. Create docker-compose.yml in /home/core/, replacing the $variables with your values
2. Create nginx.tmpl in /var/lib/docker/volumes/wpserver_nginx_templates/_data/
3. Create wp-server.service in /etc/systemd/system/
4. Run sudo systemctl daemon-reload to load the new service file
5. Run sudo systemctl start wp-server to start the WordPress Server
6. Run sudo systemctl status wp-server to make sure everything is running
7. Run sudo systemctl enable wp-server to enable the WordPress Server to start at boot

Notes

1. Thanks to jwilder for the Nginx-Proxy
2. There may be a better way to copy the nginx.tmp file, but after many attempts, the named volume was the easiest.
