TektonChain Default Configuration

Epic Goal

• Provide a default TektonChain configuration that OOTB that covers the majority of customer use cases

Why is this important?

• Customers new to chains and signing will struggle with terminology to configure chains successfully. Chains should just be a bring your signing-secret and it works type of thing

Scenarios

1. Customer wants to use Chains
2. Customer reads docs about configuration and gets frustrated

Acceptance Criteria (Mandatory)

• Default configuration works on the box for taskrun, pipelinerun and OCI image signing
