ddev behind corporate proxy

Question

I want the ddev web container to use my corporate proxy settings. Else when i run composer diagnose i end up with this:

uid_1000@d24b5fb17f37:/var/www/html$ composer diagnose

diagnose

And i can't use composer properly.

I need a way to pass the environnement variables HTTP_PROXY, HTTPS_PROXY and NO_PROXY to the container, how can i achieve this?

Update :

Well, after reading a bit of docker documentation, there is an existing way to define a proxy properly... See https://docs.docker.com/network/proxy/

By creating on the host the file ~/.docker/config.json with

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://ip:port",
     "httpsProxy": "http://user:password@ip:port,
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

then ddev restart docker will automatically set the needed ENV vars, lowercase and uppercase.

With this, composer works, wget works. apt still doesn't works form inside the container, because it still need proxy settings in a /etc/apt/apt.conf.d/20proxyconf file, but it works from a .ddev/web-build/Dockerfile, i think that's enough :)
