You must configure the base operating system of your node machines to use Anthos on bare metal. This page contains the steps you need to take to complete the needed configuration. For more information about troubleshooting Anthos on bare metal requirements, see the troubleshooting guides.
Before you begin
Ensure you are using a supported version of your operating system. Anthos on bare metal supports the following versions for Ubuntu:
Validate package manager:
sudo apt-get check
The output should show no errors and look similar to the following example:
# Reading package lists... Done # Building dependency tree # Reading state information... Done
sudo systemctl stop apparmor
sudo systemctl disable apparmor
AppArmorappears as inactive:
sudo systemctl status apparmor | grep "Active"
# Active: inactive (dead) ...
sudo ufw disable
sudo ufw status # Status: inactive
Configuring Docker 19.03+ on your workstation
Anthos on bare metal helps you install Docker on your bare metal machines in the following scenarios:
- If your bare metal machines don't have Docker installed,
bmctlinstalls 19.03.13 or later.
- If your bare metal machines have Docker 19.03.5 or earlier installed,
bmctlupgrades Docker to version 19.03.13 or later.
Follow these steps to manually install Docker:
Remove any previous Docker version:
sudo apt-get remove docker docker-engine docker.io containerd runc
Update your package manager:
sudo apt-get update
Install Docker 19.03+:
sudo apt-get install \ apt-transport-https \ ca-certificates \ curl \ gnupg-agent \ software-properties-common \ docker.io
Verify you are now running version 19.03+:
sudo docker version
Compare your output with the following example to ensure the Client and Server versions are 19.03+ :
Client: Docker Engine - Community Version: 19.03.13 ... Server: Docker Engine - Community Engine: Version: 19.03.13
