Configure Docker to use a proxy server

I have installed docker on windows , when I try to run hello-world for testing on docker. I get following error

Unable to find image

My computer is using proxy server for communication. I need to configure that server in the docker. I know proxy server address and port. Where I need to update this setting. I tried using https://docs.docker.com/network/proxy/#set-the-environment-variables-manually. It is not working.

dockerd config-file : /etc/docker/daemon.json

{
  "proxies": {
    "http-proxy": "http://127.0.0.1:12333",
    "https-proxy": "http://127.0.0.1:12333",
    "no-proxy": ""
  }
}

I had the same problem on a windows server and solved the problem by setting the environment variable HTTP_PROXY on powershell:

[Environment]::SetEnvironmentVariable("HTTP_PROXY", "http://username:password@proxy:port/", [EnvironmentVariableTarget]::Machine)

And then restarting docker:

Restart-Service docker

More information at Microsoft official proxy-configuration guide.

Note: The error returned when pulling image, with version 19.03.5, was connection refused.

The answer of Alexandre Mélard at question Cannot download Docker images behind a proxy works, here is the simplified version:

  1. Find out the systemd script or init.d script path of the docker service by running:service docker status or systemctl status docker, for example in Ubuntu16.04 it's at /lib/systemd/system/docker.service

  2. Edit the script for example sudo vim /lib/systemd/system/docker.service by adding the following in the [Service] section:

     Environment="HTTP_PROXY=http://<proxy_host>:<port>"
 Environment="HTTPS_PROXY=http://<proxy_host>:<port>"
 Environment="NO_PROXY=<no_proxy_host_or_ip>,<e.g.:172.10.10.10>"
  3. Reload and restart the daemon: sudo systemctl daemon-reload && sudo systemctl restart docker or sudo service docker restart

  4. Verify: docker info | grep -i proxy should show something like:

    HTTP Proxy: http://10.10.10.10:3128
HTTPS Proxy: http://10.10.10.10:3128
  5. This adds the proxy for docker pull, which is the problem of the question. If for running or building docker a proxy is needed, either configure ~/.docker/config as the official docs explained, or change Dockerfile so there is proxy inside the container.

Try setting the proxy. Right click on the docker icon in system tray, go to settings, proxy and add the below settings:

"HTTPS_PROXY=http://<username>:<password>@<host>:<port>"

If you are looking to set a proxy on Linux, see here
