    Docker Desktop is not respecting proxy settings under Windows 10 Professional

SOLUTION:


Option 1:configure Docker Desktop to use Manual proxy settings: the "whale" context menu / Settings / Resources / Proxies / Manual proxy configuration
Option 2: (might work, didn't test) set HTTP_PROXY / HTTPS_PROXY / NO_PROXY as system environment variables, not user ones

In both cases, restart Docker Server
Original Problem:

I work in a corporate environment behind a proxy, so that all outgoing HTTP/HTTPS request must go through http://proxy.mycorp.domain:80
So, I have:

environment variables:

HTTPS_PROXY=http://zscaler.proxy.mycorp.domain:80
HTTP_PROXY=http://zscaler.proxy.mycorp.domain:80
NO_PROXY=.mycorp.domain,localhost,appserver.vagrant,192.168.0.0/16,192.168.99.100


%USERPROFILE%\.docker\config.json contains:

  "proxies": {
    "default": {
      "httpProxy": "http://zscaler.proxy.mycorp.domain:80",
      "httpsProxy": "http://zscaler.proxy.mycorp.domain:80",
      "noProxy": "*.mycorp.domain,localhost,appserver.vagrant,192.168.0.0/16,192.168.99.100,git.mycorp.domain,repository.mycorp.domain"
    }
  }
However, when I run docker run hello-world, or docker pull hello-world:latest, I see this:
Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

which looks like a pretty clear indication of not abiding to proxy setup
in the %APPDATA%\Docker\log folder, there is docker.log file, where I have this:
2020-03-06T09:35:16Z docker time="2020-03-06T09:35:16.692313962Z" level=debug msg="Trying to pull hello-world from https://registry-1.docker.io v2"

What am I missing here? Before enabling Hyper-V and installing Docker for Windows, I've been using Docker Toolbox, and it took quite some time to figure the proper setup out,
but I am sure it did work, eventually.
How to configure a Docker Desktop properly? Or how to enable most verbose logging possible to figure out the issue ?
Thanks!
