Issues that can arise when using the installer
The installers are built to be idempotent so that they can be run multiple times, and always be left with a complete install. However, there will be times when errors occur during installation, leaving things with a partial install. Therefore, when upgrading an installation from one version to another, the best practice is to back up the current installation.
In addition, there are times when it may not seem worth the time to diagnose the problem. So, using VMs in some form allows the user to create snapshots of a clean installation of the operating system before installation.
On every installation, the Ansible playbook output is saved to setup.log in the same folder where you ran ./setup.sh. When an error occurs, you will see an output similar to the following:
cat setup.log
TASK [ansible.automation_platform_installer.repo_management : Enable Automation Platform rhsm repository] ***
fatal: [controller.node]: FAILED! =>...
