public Optional<Output<Map<String,String>>> binaryData() {
        return Optional.ofNullable(this.binaryData);
    }
@return BinaryData contains the binary data. Each key must consist of alphanumeric characters, &#39;-&#39;, &#39;_&#39; or &#39;.&#39;. BinaryData can contain byte sequences that are not in the UTF-8 range. The keys stored in BinaryData must not overlap with the ones in the Data field, this is enforced during validation process. Using this field will require 1.10+ apiserver and kubelet.
