Custom Certificate Authorities

How to supply custom certificate authorities

Appending the Certificate Authority

Append additional certificate authorities to the system’s trusted certificate store by patching the machine configuration with the following document:

apiVersion: v1alpha1
kind: TrustedRootsConfig
name: custom-ca
certificates: |-
    -----BEGIN CERTIFICATE-----
    ...
    -----END CERTIFICATE-----    

Multiple documents can be appended, and multiple CA certificates might be present in each configuration document.

This configuration can be also applied in maintenance mode.
