Summary and Scope

Since we have a /v1/ compliant cert-manager now, update usage of the certmanager api to /v1/ to be proactive about future updates which will remove all pre /v1/ api's entirely.

Testing

dorian

Tested on:

• <development system>
• Local development environment
• Virtual Shasta dorian

Test description:

Installed on dorian and let the issuers refresh after a day or two and validated we no longer have any old api usage for this chart.

• Were the install/upgrade-based validation checks/tests run (goss tests/install-validation doc)?
• Were continuous integration tests run? If not, why?
• Was upgrade tested? If not, why?
• Was downgrade tested? If not, why?
• Were new tests (or test issues/Jiras) created for this change?

Risks and Mitigations

n/a not backwards compatible with pre 1.5 as that cert-manager only has alpha apis.
