Setting Up the Deploy Node
...
The deploy node will coordinate all other installation and operations, so it needs to be set up first. In the test installation, the deploy node is a VM running on a x86 PC, with Ubuntu Linux 20.04 installed. In addition, the Ansible tool must be installed. The Ansible tool provided in the Ubuntu software repository is a slightly older version which needs to be upgraded, but it is sufficient to execute the setup_deploy.yml playbook, which will install the newer version of Ansible and other tools required on the deploy node. But before running that playbook you need to configure a few things described in the section below.
The playbooks for use on the deploy node are stored in the deploy/playbook directory of the source repository. These playbooks refer to other files in the source code, so the entire directory tree should be copied onto the deploy node. The easiest way to do this is by cloning the git repository directly as shown below:
git clone <repository-url>
Note, using the --depth=1 option can save some disk space.
The git command will create a directory in the directory where it is run named after the repository. Inside the new directory will be the deploy/playbook directory. Unless noted otherwise, the commands below should be run in that directory.

Set Up the Deploy Node
After setting the configuration variables in the master.yml and hosts files, you can run the setup_deploy.yml playbook using the command below.
ansible-playbook -i ./hosts setup_deploy.yml
