Puppet kubernetes module - kubernetes

Question

I installed the puppet kubernetes module to manage pods of my kubernetes cluster with https://github.com/garethr/garethr-kubernetes/blob/master/README.md
I am not able to get any pod information back when I run
puppet resource kubernetes_pod
It just returns an empty line.
I am using a minikube k8s cluster to test the puppet module against.
cat /etc/puppetlabs/puppet/kubernetes.conf
apiVersion: v1
clusters:
- cluster:
certificate-authority: /root/.minikube/ca.crt
server: https://<ip address>:8443
name: minikube
contexts:
- context:
cluster: minikube
user: minikube
name: minikube
current-context: minikube
kind: Config
preferences: {}
users:
- name: minikube
user:
client-certificate: /root/.minikube/apiserver.crt
client-key: /root/.minikube/apiserver.key
I am able to use curl with the certs to talk to the K8s REST API
curl --cacert /root/.minikube/ca.crt --cert /root/.minikube/apiserver.crt --key /root/.minikube/apiserver.key https://<minikube ip>:844/api/v1/pods/

Answer 1

It looks like the garethr-kubernetes package hasn't been updated since August 2017, so you probably need a version of the kubeclient gem at least that old. It seems kubeclient 3.0 came out quite recently, so you might want to try the latest version from the 2.5 major (currently 2.5.2).

Answer 2

From the requirements, this could be related to a credentials issue.
Or the configuration is set to a namespace with nothing in it.
As show in this issue, check the following:
kubectl get pods works fine at the command line, and my ~/.puppetlabs/etc/puppet/kubernetes.conf file is generated as suggested:
mc0e#xxx:~$ kubectl config view --raw=true
apiVersion: v1
clusters:
- cluster:
server: http://localhost:8080
name: test-doc
contexts:
- context:
cluster: test-doc
user: ""
name: test-doc
current-context: test-doc
kind: Config
preferences: {}
