Kubernetes core/Service: targetPort doesn't accept number

[cmbankester]

Resource Type

Kubernetes core/Service

Api Version

v1

Issue Type

Inaccurate property type(s)

Other Notes

Property spec.ports.targetPort has warning when proving it with a number. The description for the property says:

IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

Providing a stringified number, (e.g. '8080') produces an error during deployment, so a number is required here. Providing a number here produces this warning:

The property "targetPort" expected a value of type "null | string" but the provided value is of type "8080". If this is a resource type definition inaccuracy, report it using https://aka.ms/bicep-type-issues
