Experimental DNS server to act as a proxy_pass resolver for nginx to bounce your requests to depending on SQLite lookup data

Experimental Python based DNS server that lets you use SQLite as a nginx proxy_pass resolver that performs an SQLite query to decide where to resolve/pass proxy_pass the request to.

( Asks a SQLite DB what the real IP for a lookup should be and returns that so proxy_pass can use it )

Based on https://github.com/paulc/dnslib/blob/master/dnslib/fixedresolver.py

docker-compose up

Then

• http://127.0.0.1/google Lookup "google" in the SQLite then resolve to an IP that hopefully still works and proxy_pass you there
• http://127.0.0.1/test-container Fallback example, key doesnt exist so we fallback to using the existing defined docker hosts/containers

See

• http://nginx.org/en/docs/http/ngx_http_core_module.html#resolver
