Ansible install and scripts for a class on ansible
ansible's Introduction
Ansible Automation Scripts for CentOS 8
- By default Ansible checks
/etc/ansible/hosts for the default hosts file.
- I recommend changing the host(s) IP addresses to reflect your network layout.
- I recommend then putting hosts in /etc/ansible/
- By default Ansible checks /etc/ansible/vars for default vars
- I did not use any default vars - this file is not required for this scenario, but you could create a file and define puppet vars there
- The shell script installs ansible without any of the default files - if people install it differently, they may see different results
- All of the above is subject to change without notice - welcome to continuous delivery.
- Finally - google is your friend. If you don't understand something, search first, try something second, ask third.
Recommended Sequence of Actions:
- copy ansibleInstall.sh onto target Cent OS 8 VM
- vim ansibleInstall.sh and see what it is you are about to run
- chmod +x ansibleInstall.sh
- After you understand it, run ./ansibleInstall.sh
- copy playbook.yaml onto target control Cent OS 8 VM in your home directory
- copy hosts onto target control Cent OS 8 VM into /etc/ansible directory
- vim playbook.yaml and see what it is doing
- After you understand playbook.yaml, run ansible-playbook playbook.yaml
- troubleshoot all errors
Note: I added my gitPlaybook.yaml just as another use case.
This is an example of automating even code updates.
