Error when load yaml with parameters

[marlonpatrick]

To reproduce the error run the code below with an multi-document yaml. Parameters must have the format ${param1}.

public static void main(String[] args) {
	try(DefaultKubernetesClient client = new DefaultKubernetesClient()){
		
    	Map<String, String> parameters = new HashMap<>();
    	parameters.put("param1", "value1");
    	parameters.put("param2", "value2");

        client.load(MyClass.class.getResourceAsStream("/my-multiple-document.yaml"))
            	.withParameters(parameters).inNamespace("myNamespace").get();
	}
}

Log:

Hmm, I'm not sure whether we supported replacing parameters earlier in Kubernetes manifests, it was only specific for templates I think(I might be wrong). Was it working for you in previous versions? If not, I think it's not a bad idea to support this in regular manifests too.

Hey guy,

I had never tested it in other versions, but the same document works when using Serialization.unmarshal.

So, from what I looked at quickly, it is as if he had been calling the method Serialization.unmarshal 2 times, once with the empty string which causes the error.
