+Microsoft ships the latest [Azure CLI](https://github.com/azure/azure-cli) as a [Docker image](https://hub.docker.com/r/azuresdk/azure-cli-python/).

The extension will then run an interactive terminal attached to the container.

From there, set the subscription you want to work with using `az account set` (you can see all of your subscriptions with `az account list`). You do not need to login in every time you run the container becasue the extension volume mounts the local `$HOME/.azure` folder to the container's `$HOME/.azure` folder.
