docker-machine is deprecated

[HollisTech]

The documentation for Advanced Container Configuration, has a section 'connect using docker machine' (https://code.visualstudio.com/docs/remote/containers-advanced#_connect-using-docker-machine) , but docker-machine is deprecated and no longer provided with docker desktop for windows. Instead the docker docs suggest simply using the environment variable DOCKER_HOST for remote server docker operations.

Thanks for reporting @HollisTech! Would you be able to share where in the Docker docs it mentions docker-machine is deprecated? I can't seem to find it on https://docs.docker.com/machine/

That section is in the section "Superseded products and tools." Also see docker/machine#4537. Docker for windows incorporates machine functionality using either the --machine parameter or the DOCKER_HOST environment variable.

The Docker extension comes with docker.host (same as DOCKER_HOST env variable) and docker.context (same as DOCKER_CONTEXT env variable) user settings that are also honored by the Remote-Containers extension.

Docker contexts seem to be the newer concept and could be mentioned in the documentation instead of docker-machine: https://docs.docker.com/engine/context/working-with-contexts/

Note that the above settings are only visible when the Docker extension is installed. Without the Docker extension, Remote-Containers will use the current context. The current context can be changed using docker context use <context>.
