Onboard Tekton Scheduler to operator #2934

pramodbindal · 2025-10-30T07:01:01Z

Changes

Onboarding Tekton Scheduler to operator.

Tekton Scheduler enables the pipeline scheduling on Single or multi cluster environment. But default this feature remains disabled.

This feature is dependent on upstream Kueue so that must be installed first before scheduler can be enabled. It also uses cert-manager so that also must be installed before head.
