Charter

Mission

The Knative Operation Working Group provides best practices for managing, assessing system health and maintaining Knative clusters. The initial focus will be on how Knative is installed, removed, and upgraded.

Goals

• Provide a means to install Knative [Serving/Build/Eventing] with operator(s) specified options
  • Operator specified defaults such as timeouts and concurrency
  • Network preferences, Istio / Gloo / others
  • Build Template selection
  • Eventing component selection
• Provide a means to install Knative with limited/no internet access
• Provide a means to upgrade/downgrade Knative with limited/no user visible impact to their service
• Provide guidelines on determining the overall health of Knative
• Provide cluster sizing and lifecycle recommendations
• An entrypoint and forum for dogfooders to give feedback

Non-Goals

• The knative operator does not manage or install Istio, or other dependents.
  • But we might want to have the option to recommend other operators for this task. Like knative.spec.istioOperator = yes please.

Scope

• Tooling for installation/removal/upgrades/downgrades
• Management mechanisms for:
  • namespace setup (if needed)
  • Quota and RBAC management
  • Build and registry configuration
  • integration with existing cluster o11y
• Debugging tools for operator personas.
• Define more specific “operator” sub-personas within the Knative “operator” persona (e.g. auditor, cloud provider, IT provider, etc)
  • Collect feedback from operators on the usability of Knative
• Collaborate w/ Documentation Working Group on documentation for installation/removal/upgrades/downgrades
• Collaborate w/ Observability Working Group on metrics for health of Knative
• Collaborate w/ Productivity Working Group on using best-practice installation for testing
