create_from_file YAML throws an exception: Error creating resource: the server could not find the requested resource

[guillelb]

Hello,

I am working with:

• K8S: v1.7.8
• PERL: v5.22.1

With a K8S cluster working, I launch the following PERL:

my $kube = Net::Kubernetes->new(url=>'http://127.0.0.1:8080');
my $resource = $kube->create_from_file('/etc/kubernetes/deployments/skydns-dply.yaml');

And I obtain this Exception stack:

Error creating resource: the server could not find the requested resource

On the other hand, if I deploy the same YAML from KUBECTL, everything works fine:

# kubectl create -f /etc/kubernetes/deployments/skydns-dply.yaml
deployment "kube-dns" created
