Proxy configuration propagation doesn't work.

[asakaxgit]

• I have tried with the latest version of my channel (Stable or Edge)
• I have uploaded Diagnostics
• Diagnostics ID:

Expected behavior

After setting proxies on Settings GUI (and restart), containers have environment variables related to proxy (ex. http_proxy).

Actual behavior

No proxy related environment variables was settled in a container.
According to the documentation(https://docs.docker.com/docker-for-windows/), my proxy settings propagate into the containers.

Information

• Windows Version: 10.0.17763.379
• Docker for Windows Version: 2.0.3.0 (31778)

Steps to reproduce the behavior

1. Setting "Manual proxy configuration" is on
2. "Web Server(HTTP)" to http://blahblah:1234.
3. Then click apply,
4. Restart will begin.
5. After docker's launch. "docker run alpine env" on command-line shows below
   PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin HOSTNAME=42d5ee4d97f0 HOME=/root
   No proxy related environment variables are shown!

Same here.

• Channel: stable
• Build: 8858db3

Manually adding the proxy configuration to %USERPROFILE%\.docker\config.json solved the issue for me.

"proxies": {
  "default": {
    "httpProxy": "http://1.2.3.4:8080",
    "httpsProxy": "http://1.2.3.4:8080"
  }
}

I produce the same issue on Docker for Windows 2.1.0.5

[guidoavvisati]

Same issue for me on Windows 10 and Docker 2.2.0.5. Manually changing the ~/.docker/config.json file works. If some sites need to bypass the proxy, use the noProxy variable

{
 "proxies":
 {
   "default":
   {
     "httpProxy": "http://127.0.0.1:3001",
     "httpsProxy": "http://127.0.0.1:3001",
     "ftpProxy": "http://127.0.0.1:3001",
     "noProxy": "*.test.example.com,.example2.com"
   }
 }
}

Update 13-05: I actually think that what worked for me was to set the proxy info in both the docker daemon GUI and the config.json file as per above.

@guidoavvisati I believe this has been fixed in 2.2.1.0, see https://docs.docker.com/docker-for-windows/edge-release-notes/#docker-desktop-community-2210

Fixed a bug where users were unable to modify the Manual proxy configuration settings through the Docker Desktop UI.
