Admin workstation prerequisites

The admin workstation is where you download the bmctl command-line interface (CLI) tool and install the Google Cloud CLI. The admin workstation hosts configuration files to provision clusters during installation and kubectl for interacting with provisioned clusters post-installation. The admin workstation must meet the following prerequisites:

Operating system is the same supported Linux distribution running on the cluster node machines. For more information, see, Select your operating system .
Docker version 19.03 or later installed.

Verify that Docker is in strict confinement mode by running snap info --verbose docker | grep confinement on your admin workstation. If this applies to you, make sure that the bmctl-workspace folder is in the $HOME directory.
Non-root user is member of docker group (for instructions, go to Manage Docker as a non-root user ).
