I have installed kubernetes in AWS ec2 instance. I'm not using any minikube or openshift. I'm trying to install kamel on top of kubernetes to run my integration code. When I tried to run kamel install command its throwing below error,

Error: cannot find automatically a registry where to push images

When I tried running as root user below error is thrown,

Error: cannot get current namespace: open /root/.kube/config: no such file or directory

I'd like to know what registry I have to pass while running kamel install command. I have docker hub account with a demo repository. Should I pass something like,

kamel install --registry hubusername/reponame

What I'm not getting is after I passed value, I'm getting below success message,

Camel K installed in namespace default

When I tried to run a sample groovy script its getting hanged after following message

kamel run hello.groovy --dev
Integration "hello" created
