Build Operators

Install the operator-sdk tool. See the official documentation.

Operators can be built using 3 different approaches:

• Helm: a framework to define the deployment logic based on regular kubernetes YAML, but less capabilities for complete auto-update and insights.
• Ansible: define the deployment logic with Ansible, provide maximum capabilities.
• Golang: define the deployment logic in Golang, provide maximum capabilities, but require more code.
