docker.ir see this page

for iranian people , you must see this page and use it's mirror and proxy server . thank you :) , none of the previous steps are requierd .

just add docker.ir proxy server in ~/.docker/config.json and add mirror to /etc/docker/daemon.json . FUCK IRAN AND FUCK DOCKER .

sudo mkdir -p /etc/systemd/system/docker.service.d

sudo touch /etc/systemd/system/docker.service.d/http-proxy.conf

sudo nano /etc/systemd/system/docker.service.d/http-proxy.conf

inside the .../http-proxy.conf:

[!WARNING] HTTPS is not HTTPS ! in some cases you have to put the http:// instead of https inside of HTTPS_PROXY variable . if proxy is not working try to do this .

[Service]
Environment="HTTP_PROXY=http://example.com:3129"
Environment="HTTPS_PROXY=https://example.com:3129"
# Environment="NO_PROXY=localhost,127.0.0.1

[!IMPORTANT] reload the docker in some cases like this you have to reload the docker to new settings be loaded in program and work correctly .

sudo systemctl daemon-reload && \
sudo systemctl restart docker

verify completed everything fine :

sudo systemctl show --property=Environment docker

you should see something like this:

Environment=HTTP_PROXY=http://example.com:3129 HTTPS_PROXY=http://example.com:3129
