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 ofdocker group (for instructions, go to Manage Docker as a non-root user).
