Interesting, although I specifically wanted to build a push CDN (where I can push the content) rather than a pull CDN (that works with an origin) to avoid the added latency with cache misses.
Ansible is running docker-compose up -d on deployment an Traefik is doing the magic. I want to extend it to host multiple sites in the future. (Btw. Ansible ran from a central location is painfully slow because of the large latency to the edge nodes.)
The content itself is deployed using rsync, Ansible was just too painfully slow for that.
