- 3. Ansible API
- 4. Ansible API Use Cases • Server Provisioning Automation • Wrapping Ansible calls in scripts • Gaining deeper understanding of the Ansible internals
- 5. Best Examples – Ansible Code Itself! Ansible Ansible Playbook
- 6. Breaking it Down – Ansible API 3 module parameters • Module Name • Module Path • Module Arguments Several Authentication Options • Remote user / pass • User / pass / options for su(do) • Vault password • Private Key
- 7. Breaking it Down – Ansible API • Inventory / Pattern / Subset • Timeout • Forks • Callbacks • Transport method • Check / Diff options
- 8. Breaking it Down – Ansible-Playbook API Shares many of the same arguments Includes new arguments: • Playbook (obviously!) • Callbacks for runner and playbook • Stats • Extra variables • Tag logic (skip, only) • Force / flush handlers
- 9. Inventory Management • Need to define inventory • Can define subset • Easy to instantiate
- 10. Ansible Plugins Types of plugins: • Connection Type • Lookup • Vars • Filter • Callbacks
- 11. Callback Plugins – Ooo, interesting… • Customize actions • Aggregate/manipulate results • Create historic logs and dashboards
- 12. Examples!
- 13. Questions? There are some “less good” ones…
Editor's Notes
- #11: CONNECTION TYPE The connection type plugins allow you to add additional connection types. I’m not really sure what the use case would be unless you’re trying to support other operating systems. LOOKUP TYPE Lookup plugins allow access of data in Ansible from outside sources VARS TYPE Provide additional ways to get variables FILTER TYPE Provide additional filters on top of Jinja2 CALLBACKS TYPE Calling back to report data
- #12: With callback plugins, you can have a little bit more power over your ansible runs and how your code tracks data. There are also some great examples online already. As silly as it may seem,
