Lessons from Building an Operator Using Operator SDK and Ansible
summary
A project built an operator called M4e-operator using Operator SDK with Ansible to manage Moodle on Kubernetes (repo github.com/krestomatio/m4e-operator). The design encodes Moodle lifecycle into custom resources, implements lifecycle steps as Ansible roles/collections and a dynamic inventory plugin to execute commands against pods. Initial reconciliation ran ~60 Ansible tasks (>1 min) then was trimmed to ~40 tasks (~50 s) and scaled to 220 instances with ~5 min cycles; using community Turbo Mode caching reduced cycle time toward ~20 s, while performance, debugging and upgrade testing remain work in progress.
