Docker CLI

As explained in Learn Docker in a Month of Lunches, Second Edition

Docker CLI is the command-line interface for interacting with Docker.

Docker CLI is the command-line client for Docker’s HTTP-based API. It sends requests to the Docker Engine, which manages images, containers, networks, and other Docker resources. section 2.5

Use the CLI to:

• Manage containers on the local computer or on a remote Docker host. section 2.5
• Execute Dockerfile steps for packaging application components. section 11.0
• Start and stop application stacks described by Docker Compose files. section 11.0
• Run scripted Docker workflows inside automation and continuous-integration jobs. section 11.0

How Learn Docker in a Month of Lunches, Second Edition covers it

How deep it goes

Explains the CLI–API–Engine architecture and remote control, but stops short of deeper containerd implementation details.

Examples

Uses local and remote container management, Dockerfile packaging, Compose stack control, and scripted CI jobs.

What it assumes

Assumes basic Docker resources and files while introducing the CLI, API, Engine relationship from first principles.

What you can do after

Operate/configure Docker workflows locally, remotely, and within automated build and test processes.

How it connects

Ties Docker CLI to Docker API, Docker Engine, containers, images, Dockerfile, Docker Compose, and continuous integration.
