Key Takeaways

Awesome features coming soon

Can achieve one-man ops

Extending ansible is simple

WP Engine’s Use Case

Needed to improve user management process

Wrote a front-end interface

Wrote a stupid simple plugin

Create directory in project root (lookup_plugins)

Write stupid simple plugin in that directory

Use with_{SCRIPT_NAME} in playbook

Profit!

Wait… That easy?

Yes. That’s it.

User management can now be handled with an API call
