= Allowed CRD upgrade changes
|
|
|
|
The following changes to an existing custom resource definition (CRD) are safe for backwards compatibility and will not cause the CRD upgrade safety preflight check to halt the upgrade:
|
|
|
|
- Adding new enum values to the list of allowed enum values in a field
|
|
- An existing required field is changed to optional in an existing version
|
|
- The minimum value of an existing field is decreased in an existing version
|
|
- The maximum value of an existing field is increased in an existing version
|
|
- A new version of the CRD is added with no modifications to existing versions |
