What is a Docker context?

A Docker context is essentially a named configuration that allows users to connect to different Docker engines or daemons seamlessly. It enables developers to manage multiple environments, such as local and remote Docker instances, without needing to switch configurations constantly. By setting up different contexts, users can specify various settings such as the Docker host, TLS settings, and the location of certificates, making it easier to switch between different setups based on the needs of a project or workflow.

This flexibility is particularly useful for developers who work in multiple environments—like a local machine versus a cloud-based Docker service—allowing them to execute commands against the desired environment with just a context switch. Understanding Docker contexts streamlines operations and enhances productivity in container management by maintaining different configurations easily.
