Open Policy Agent Config Schema¶

Note

This is auto-generated documentation from a JSON schema that is under construction, this will improve over time.

https://raw.githubusercontent.com/elastisys/compliantkubernetes-apps/main/config/schemas/config.yaml#/properties/opa

Configure Open Policy Agent, constraints and mutations enforced by Gatekeeper.

Welkin contains multiple safeguards to make it easy to follow security best practices.

This includes an implementation of constraints and mutations with similar behaviour as Pod Security Policies, and application developer centric safeguards.
