A Docker context is a Docker CLI configuration containing the endpoint and connection details for a Docker Engine. Contexts let the CLI and Buildx work with different engines, including remote engines in a build farm. section 12.4
Docker context
A Docker context is a Docker CLI configuration that specifies the endpoint and connection details for a Docker Engine.
How Learn Docker in a Month of Lunches, Second Edition covers it
- How deep it goes
- Defines contexts and demonstrates creation and inspection, while deferring detailed network listener and security setup.
- Examples
- Demonstrates duplicating the default context and using the copy as a second Buildx build node.
- What it assumes
- Assumes Docker CLI access and a current default context, while teaching context duplication from the shown commands.
- What you can do after
- Operate Docker contexts via the Docker CLI and attach them to Buildx builders.
- How it connects
- Connects Docker CLI contexts with Docker Engine, Buildx, build nodes, multi-platform images, SSH, and TLS.
