As you edit your inventory file, there are a few things you must keep in mind:
The contents of the inventory file should be defined in ./inventory, next to the ./setup.sh installer playbook.
For installations and upgrades: If you need to make use of external databases, you must ensure the database sections of your inventory file are properly setup. Edit this file and add your external database information before running the setup script.
For Ansible Automation Platform or Automation Hub: Be sure to add an automation hub host in the [automationhub] group (Tower and Automation Hub cannot be installed on the same node)
For upgrading an existing cluster: When upgrading a cluster, you may decide that you want to also reconfigure your cluster to omit existing instances or instance groups. Omitting the instance or the instance group from the inventory file will not be enough to remove them from the cluster. In addition to omitting instances or instance groups from the inventory file, you must also deprovision instances or instance groups before starting the upgrade. Otherwise, omitted instances or instance groups will continue to communicate with the cluster, which can cause issues with tower services during the upgrade.
For clustered installations: If you are creating a clustered setup, you must replace localhost with the hostname or IP address of all instances. All nodes/instances must be able to reach any others using this hostname or address. In other words, you cannot use the localhost ansible_connection=local on one of the nodes AND all of the nodes should use the same format for the host names.
Therefore, this will not work:
[tower]
localhost ansible_connection=local
hostA
hostB.example.com
172.27.0.4
Instead, use these formats:
[tower]
hostA
hostB
hostC
OR
hostA.example.com
hostB.example.com
hostC.example.com
OR
[tower]
172.27.0.2
172.27.0.3
172.27.0.4
For all standard installations: When performing an installation, you must supply any necessary passwords in the inventory file.
Note
Changes made to the installation process now require that you fill out all of the password fields in the inventory file. If you need to know where to find the values for these they should be:
admin_password=''<— Tower local admin password
pg_password=''<—- Found in /etc/tower/conf.d/postgres.py
Warning
Do not use special characters in pg_password as it may cause the setup to fail.
For provisioning new nodes: When provisioning new nodes add the nodes to the inventory file with all current nodes, make sure all passwords are included in the inventory file.
For upgrading a single node: When upgrading, be sure to compare your inventory file to the current release version. It is recommended that you keep the passwords in here even when performing an upgrade.

Once any necessary changes have been made, you are ready to run ./setup.sh.
Note
Root access to the remote machines is required. With Ansible, this can be achieved in different ways:
ansible_user=root ansible_ssh_pass=”your_password_here” inventory host or group variables
ansible_user=root ansible_ssh_private_key_file=”path_to_your_keyfile.pem” inventory host or group variables
ANSIBLE_BECOME_METHOD=’sudo’ ANSIBLE_BECOME=True ./setup.sh
ANSIBLE_SUDO=True ./setup.sh (Only applies to Ansible 2.7)
The DEFAULT_SUDO Ansible configuration parameter was removed in Ansible 2.8, which causes the ANSIBLE_SUDO=True ./setup.sh method of privilege escalation to no longer work. For more information on become plugins, refer to Understanding Privilege Escalation and the list of become plugins.
