Client and daemon

When you install Docker, you get two major components:

• The Docker client
• The Docker daemon (sometimes called the “Docker engine”)

The daemon implements the runtime, API, and everything else required to run Docker.

In a default Linux installation, the client talks to the daemon via a local IPC/Unix socket at /var/run/docker.sock. On Windows, this happens via a named pipe at npipe:////./pipe/docker_engine. Once installed, you can use the docker version command to test that the client and daemon (server) are running and talking to each other.

Check the Docker installation in the terminal below:
