VSCode Docker extension cannot connect to docker machine

Question

I'm unable to configure the VSCode Docker extension by Microsoft to connect to a docker-machine via setting of the DOCKER_HOST environment variable.

.zshrc

export DOCKER_HOST="tcp://192.168.99.100:2376"

I have:

Run source ~/.zshrc and restarted VSCode
Logged out and reopen VSCode

Has anyone else run into this issue before and found a fix?

Port 2376 in your DOCKER_HOST implies your docker daemon is most likely running on TLS.

Assuming it is, you also need to set a DOCKER_CERT_PATH environment variable.

On my (default Windows) installation, its value is C:\Users\mike\.docker\machine\machines\default.

This does seem like a glaring omission from the documentation, so I went ahead and raised a PR.
