    The selector key-value pair placed on the Service, the <key> being the selector key, the value being the selector value.

    my-app
    
    v1
    

    These selectors are used to correlate with pod labels. Each selector key-value pair becomes a separate attribute.

    Examples:

    • A selector app=my-app SHOULD be recorded as the k8s.service.selector.app attribute with value "my-app".
    • A selector version=v1 SHOULD be recorded as the k8s.service.selector.version attribute with value "v1".

    This attribute is experimental and is subject to breaking changes in minor releases of @opentelemetry/semantic-conventions.
