This is a very simple, but functional, Reverse Proxy with caching, that can be used as your own CDN, with good defaults that almost work out of the box. Uses docker.
Quickstart:
$ git clone [email protected]:alligo/reverse-proxy-cdn.git
$ cd reverse-proxy-cdn
$ docker build -t alligo/reverse-proxy-cdn .
$ docker run --rm -p 80:80 -p 443:443 --ulimit memlock=9223372036854775807 --name simplecdn alligo/reverse-proxy-cdnJust to keep it simple, this solution uses just one docker container instead of make one container for NGinx, Varnish and the Crawler.
Default configurations files are on folder [configuration/_default]. Any custom change, just copy file from a path without _default, and make your changes.
Debug:
$ docker exec -it simplecdn bash
$ docker run --rm -p 80:80 -p 443:443 -p 8888:8888 -p 8080:8080 --ulimit memlock=9223372036854775807 --name simplecdn alligo/reverse-proxy-cdnTest to proxy http://cdn.fititnt.org/img/emerson-rocha-luiz.jpg
