Roll Your Own Operator with Ansible
summary
Claims that you can build a real Kubernetes Operator by wiring Ansible roles into the Operator SDK and that it actually runs a reconcile loop which executes those roles via ansible-runner. Demonstrates using the k8s module to create templated manifests from CR spec fields, shows the container image (base + roles) and the simple mapping file watches.yaml that links group/version/kind to a role, and scaffolds a memcached operator to prove the approach works.
