Ansible
Ansible is a configuration management tool used for application deployment and environment setup.
Example Ansible playbooks
Ansible is far easier to learn when you can read how more full-featured playbooks are built using many tasks. An interesting note from my own experience is that when you get more experienced using Ansible there are many shortcuts in the task syntax so you can often make playbooks that have fewer lines of code than when you were less experienced yet the readability does not suffer.
Check out some of these example playbooks to learn more about how you may be able to structure your playbooks:
