Docker provides built‑in support for using proxy servers when accessing external networks.
Administrators should review and follow the official Docker guidance for configuring proxy access with the Docker CLI and Docker daemon.
Follow the instructions in Use a proxy server with the Docker CLI in the Docker documentation.
Once basic Docker proxy support is configured, confirm that Docker commands executed on the host can reach external networks through the proxy.
Important: For enterprise networks that perform TLS inspection, additional trust configuration is required at the host and container build levels. See Using Docker with TLS-Inspecting Proxy Servers.
