beginnerDocker Architecture, Engine, Daemon, Client & Registry

How does the Docker CLI communicate with the daemon?

By default over a Unix domain socket at /var/run/docker.sock, using a versioned REST API (e.g., /v1.46/containers/json). It can also be configured to use a TCP socket (optionally with TLS) or SSH for remote daemons, controlled via the DOCKER_HOST environment variable or `docker context`.
