Build Your Kubernetes Operator with the Right Tool!
summary
Walks through building a Hazelcast operator end to end: generate with operator-sdk init and operator-sdk create api, docker build and push, run make install and make deploy, apply a CRD that sets size 1 to 3 and the operator creates and scales pods successfully. Compares Helm (templated charts, simplest), Ansible (powerful but uncommon), Go (full imperative control, most operators on Operator Hub), Python/Java or raw implementations (more boilerplate, no scaffolding).
