I try and deploy an app in a kubernetes cluster following these instructions

https://cloud.ibm.com/docs/containers?topic=containers-cs_apps_tutorial#cs_apps_tutorial

Then I make a build following the instructions with ibmcloud cr build -t registry..bluemix.net//hello-world:1 .

Output looks good except a securitywarning

SECURITY WARNING: You are building a Docker image from Windows against a non-Windows Docker host. All files and directories added to build context will have '-rwxr-xr-x' permissions. It is recommended to double check and reset permissions for sensitive files and directories.

But as this was just a test I did not worry.

At the next stage running this command following instructions

kubectl run hello-world-deployment --image=registry..bluemix.net//hello-world:1

I get the following error error: failed to discover supported resources: Get http://localhost:8080/apis/apps/v1?timeout=32s: dial tcp [::1]:8080: connectex: No connection could be made because the target machine actively refused it.

As you see in the message it looks like it is trying to do something to my local PC rather than the IBMCloud. What have I missed to do?
