Setting Up Docker with Proxy on Ubuntu Server

\n\n

In this guide, we will walk through the process of configuring Docker to work behind an HTTP proxy on an Ubuntu server. This setup is essential for environments where direct internet access is restricted.

\n\n

Step 1: Verify Docker Installation

\n\n

First, let's confirm that Docker is installed and check its version:

\n\n
root@ubuntuserver:/home/zw# docker --version\nDocker version 27.2.0, build 3ab4256\n
\n\n

If Docker is not installed, you can follow the official Docker installation guide for Ubuntu.

\n\n

Step 2: Create Configuration Directory

\n\n

Next, we need to create a directory for Docker's systemd service overrides:

\n\n
root@ubuntuserver:/home/zw# sudo mkdir -p /etc/systemd/system/docker.service.d\n
\n\n

Step 3: Create Proxy Configuration File

\n\n

Now, we will create a configuration file for the HTTP proxy. Attempting to directly edit the file will result in an error, as it does not yet exist:

\n\n
root@ubuntuserver:/home/zw# /etc/systemd/system/docker.service.d/http-proxy.conf\nbash: /etc/systemd/system/docker.service.d/http-proxy.conf: No such file or directory\n
\n\n

Instead, we will create and edit the file using vim:

\n\n
root@ubuntuserver:/home/zw# sudo vim /etc/systemd/system/docker.service.d/http-proxy.conf\n
\n\n

In this file, add the following lines to configure the proxy settings:

\n\n
[Service]\nEnvironment=\"HTTP_PROXY=http://192.168.1.241:27890/\"\nEnvironment=\"HTTPS_PROXY=http://192.168.1.241:27890/\"\n
\n\n

Step 4: Reload Systemd and Restart Docker

\n\n

After saving the configuration, reload the systemd manager configuration to recognize the new settings:

\n\n
root@ubuntuserver:/home/zw# sudo systemctl daemon-reload\n
\n\n

Then restart the Docker service to apply the changes:

\n\n
root@ubuntuserver:/home/zw# sudo systemctl restart docker\n
\n\n

Step 5: Verify Proxy Settings

\n\n

To ensure that Docker is using the proxy correctly, you can check the environment variables for the Docker service:

\n\n
root@ubuntuserver:/home/zw# sudo systemctl show --property=Environment docker\nEnvironment=HTTP_PROXY=http://192.168.1.241:27890 HTTPS_PROXY=http://192.168.1.241:27890\n
\n\n

Step 6: Pull a Docker Image

\n\n

Finally, test the configuration by pulling a Docker image. In this example, we will pull the Debian image:

\n\n
root@ubuntuserver:/home/zw# docker pull debian\nUsing default tag: latest\nlatest: Pulling from library/debian\n903681d87777: Pull complete\nDigest: sha256:aadf411dc9ed5199bc7dab48b3e6ce18f8bbee4f170127f5ff1b75cd8035eb36\nStatus: Downloaded newer image for debian:latest\ndocker.io/library/debian:latest\n
\n\n

Conclusion

\n\n

By following these steps, you have successfully configured Docker to work behind an HTTP proxy on your Ubuntu server. This allows you to pull images and perform other Docker operations in environments with restricted internet access.
