This is a repo for the article for DevOps On A Dime. The article highlights a few observations (I put together over time pieces these resouces together). The article covers an Ubuntu server provision (just use the setup.sh script) & securing an Ubuntu server. The next part deals with the Docker Compose file that uses Cloudflare, Traefik, Nginx, MariaDB, Wordpress and Redis. The article shows where you need to change a few items with your own domain and details in the .env file. The final item covered is a shell script that makes a database and plugins backup to AWS S3. You will need to install AWS CLI2 on your Ubuntu Server along with an IAM user that has S3 Bucket permissions. I put some instructions in the article how to setup a cron job to run that script.
Lastly I suggest following this awesome repo. It is a great resource for docker-compose repos and one that I used quite extensively as the basis of this stack.
