To configure Docker to use a proxy, follow these steps: 1. Create a directory for Docker service plugins: `sudo mkdir -p /etc/systemd/system/docker.service.d` 2. Create a configuration file: `sudo touch /etc/systemd/system/docker.service.d/http-proxy.conf` 3. Edit the configuration file: `sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf` 4. Add the following content, replacing the proxy IP and port as needed: ``` [Service] Environment="HTTP_PROXY=socks5://127.0.0.1:1080" "HTTPS_PROXY=socks5://127.0.0.1:1080" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com" ``` 5. Reload the service configuration: `sudo systemctl daemon-reload` 6. Restart Docker: `sudo systemctl restart docker` 7. Verify the configuration: `systemctl show --property=Environment docker` Docker will now pull files through the specified proxy. For HTTP proxy, replace "socks5" with "http".

Create the Docker service plugin directory

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

Create a file named http-proxy.conf

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

Edit the http-proxy.conf file

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

Write the content (replace the proxy IP and proxy port with your own)

[Service]
Environment="HTTP_PROXY=socks5://127.0.0.1:1080" "HTTPS_PROXY=socks5://127.0.0.1:1080" "NO_PROXY=localhost,127.0.0.1,docker-registry.somecorporation.com"

Reload the service program's configuration file

sudo systemctl daemon-reload

Restart Docker

sudo systemctl restart docker

Verify if the configuration was successful

systemctl show --property=Environment docker

At this point, Docker can pull files from the specified proxy.

Additionally, if you need to use an HTTP proxy, simply replace socks5 with http.
