"The Docker daemon - dockerd - is the heart of the container engine. It manages container lifecycle, networking, storage, images, system events, and API communication. While Docker works out of the box after installation, configuring the daemon gives administrators deeper control over performance, security, and remote access. This guide dives into the essential configurations of the Docker daemon on Linux. You'll learn how to manage Docker using systemd, debug it in foreground mode,"
"expose secure and insecure sockets, use TLS for encrypted API access, and persist configurations through the daemon.json file. By the end, you'll have a clear understanding of how the Docker daemon works and how to tune it for production. Managing Docker with systemd On most Linux distributions, Docker ships with a systemd unit file. This makes it easy to manage the Docker Engine using standard systemctl..."
Dockerd manages container lifecycle, networking, storage, images, system events, and API communication. Manage dockerd with systemd unit files and systemctl for starting, stopping, restarting, and enabling the service. Run dockerd in the foreground to debug and capture logs directly. Configure sockets to expose the API via the default Unix socket or TCP sockets, choosing secure (TLS) or insecure access as appropriate. Use TLS certificates and keys to encrypt API communication and authenticate clients and the daemon. Persist daemon options and runtime configuration in /etc/docker/daemon.json for consistent, reproducible behavior.
