Systemd using no_proxy

I’m using /etc/systemd/system/docker.service.d/http-proxy.conf to define my proxies and no_proxy. The no_proxy setting does not seem to be working and all my traffic is being route to the proxy. I have two internal networks I wanted to exclude from going through the proxy. I have tried several different ways to define them, but nothing works. Can something like, be defined in no_proxy for docker?
