Note: Anthos clusters on bare metal supports CPUs and vCPUs from the x86 processor family only. This requirement applies to your admin workstation and all cluster nodes.

• Operating system is the same supported Linux distribution running on the cluster node machines. For more information, see, Select your operating system.

  Warning: Docker installed by snap is in strict confinement mode by default, which means Docker can't access files outside the $HOME directory. 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).

  • gcloud CLI installed.
