Update to custom field in custom resource condition is silently dropped

[kangy-google]

Hello,

I added a custom field to the condition field of my CRD that looks like the following:

type CrCondition struct {
    // Ignore standard fields
    Metadata *ConditionMetadata `json:"metadata,omitempty"`
}

type ConditionMetadata struct {
    Items []ConditionMetadataItem `json:"items,omitempty"`
}

type ConditionMetadataItem struct {
    Key   string `json:"key"`
    Value string `json:"value"`
}

I was hoping to keep track of some metadata along with the condition. However, it seems that when the condition was updated, the metadata field was silently dropped. I can verify with kubectl edit. The command went through without validation error, but the output of the new resource doesn't have the metadata field. Why is this?

Is that in status?

Is that in status?

Yes, this is in status.

You have to use --subresource=status to modify status with kubectl edit

Hey, if I understand it correctly, that is for the case where subresource is enabled. I have not enabled it for my resource.

Also, other custom fields with string type can be updated just fine, so I wonder if it has anything to do with the data type.

I don't see anything obviously wrong. If those fields also exist in the CRD that you have deployed, there should be no reason why the values should be dropped
