Configure Ubuntu

Configure Ubuntu

You must configure the base operating system of your node machines to use Google Distributed Cloud. This page contains the steps you need to take to complete the needed configuration. For more information about troubleshooting Google Distributed Cloud requirements, see the known issues .

Before you begin

Ensure you are using a supported version of your operating system. Google Distributed Cloud supports the following versions for Ubuntu:

• 18.04
• 20.04

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 
 

Disable Uncomplicated Firewall (UFW)

1. Disable ufw :

    sudo ufw disable 
   

2. Check that ufw is disabled:

    sudo ufw status
   # Status: inactive 
   

Configure Docker 19.03+ on your workstation

Google Distributed Cloud helps you install Docker on your bare metal machines in the following scenarios:

• If your bare metal machines don't have Docker installed, bmctl installs 19.03.13 or later.
• If your bare metal machines have Docker 19.03.5 or earlier installed, bmctl upgrades Docker to version 19.03.13 or later.

Follow these steps to manually install Docker:

1. Remove any previous Docker version:

    sudo apt-get remove docker docker-engine docker.io containerd runc 
   

2. Update your package manager:

    sudo apt-get update 
   

3. Install Docker 19.03+:

    sudo apt-get install \
     apt-transport-https \
     ca-certificates \
     curl \
     gnupg-agent \
     software-properties-common \
     docker.io 
   

4. Verify you are now running version 19.03+:

    sudo docker version 
   

5. 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
