Learning Docker - Docker Context

Learning Docker - Docker Context

• Docker context: https://docs.docker.com/engine/context/working-with-contexts/

Features

• Docker context is a feature that allows you to switch between multiple Docker environments (local, remote, cloud) without changing the Docker CLI commands.
• Docker context supports local, SSH, and Docker API endpoints.
• Docker context can be used to manage multiple Docker environments, such as development, testing, and production.
• Docker context simplifies the management of Docker environments by providing a single configuration file for all contexts.
• Docker context allows you to define custom configurations for each context, such as environment variables, volumes, and networks.

Commands

• docker context create: Create a new Docker context.
• docker context ls: List all Docker contexts.
• docker context use: Switch to a different Docker context.
• docker context inspect: Display detailed information about a Docker context.
• docker context rm: Remove a Docker context.

Examples

• Create a new Docker context:

  docker context create mycontext --docker "host=ssh://user@hostname"
  

• List all Docker contexts:

    docker context ls
  

• Switch to a different Docker context:

  docker context use mycontext
  

• Display detailed information about a Docker context:

  docker context inspect mycontext
  

• Remove a Docker context:

  docker context rm mycontext
