Docker proxy

Posted 2021-02-15 seeken

Method One:

mkdir /etc/systemd/system/docker.service.d
vim /etc/systemd/system/docker.service.d/http-proxy.conf

[Service]
Environment="HTTP_PROXY=http://xx:80/"
Environment="HTTPS_PROXY=https://xx:80/"

If you have internal Docker registries that you need to contact without proxying you can specify them via the NO_PROXY environment variable:

Environment="HTTP_PROXY=http://proxy.example.com:80/"
Environment="NO_PROXY=localhost,127.0.0.0/8,docker-registry.somecorporation.com"

#Flush changes:
$ sudo systemctl daemon-reload

#Verify that the configuration has been loaded:
$ sudo systemctl show --property Environment docker
Environment=HTTP_PROXY=http://proxy.example.com:80/

#Restart Docker:
$ sudo systemctl restart docker

Method Two:

sudo HTTP_PROXY=http://192.168.1.1:3128/ docker pull busybox

Method Three:

vim /etc/default/docker
service docker restart

CentoOs:/etc/sysconfig/docker

Addition:
If you‘re using the new Docker for Mac (or Docker for Windows), just right-click the Docker tray icon and select Preferences (Windows: Settings),
then go to Advanced, and under Proxies specify your proxy settings there. Click Apply and Restart and wait until Docker restarts.
