I was looking for manual steps to install GLUU Kubernetes. I can see a executable python script that can do all manual step. But do we have a manual steps to install GLUU Kubernetes. When I run `./pygluu-kubernetes-linux.pyz install` am getting below error. I am using Python 3.7 in Ubuntu 16.04 ``` 2020-10-22 03:59:45,317 - gluu-common - INFO - Currently supported versions are : 2020-10-22 03:59:45,317 - gluu-common - INFO - Stable version : 4.2 2020-10-22 03:59:45,317 - gluu-common - INFO - Development version : 4.2.2_dev Traceback (most recent call last): File "/home/versa/.shiv/pygluu-kubernetes-linux_92affed69cf566e09ce7d85c7bd7d397de7240d9fa6035e5717466341bb0f460/site-packages/pygluu/kubernetes/kubeapi.py", line 28, in load_kubernetes_config config.load_incluster_config() File "/home/versa/.shiv/pygluu-kubernetes-linux_92affed69cf566e09ce7d85c7bd7d397de7240d9fa6035e5717466341bb0f460/site-packages/kubernetes/config/incluster_config.py", line 94, in load_incluster_config cert_filename=SERVICE_CERT_FILENAME).load_and_set() File "/home/versa/.shiv/pygluu-kubernetes-linux_92affed69cf566e09ce7d85c7bd7d397de7240d9fa6035e5717466341bb0f460/site-packages/kubernetes/config/incluster_config.py", line 45, in load_and_set self._load_config() File "/home/versa/.shiv/pygluu-kubernetes-linux_92affed69cf566e09ce7d85c7bd7d397de7240d9fa6035e5717466341bb0f460/site-packages/kubernetes/config/incluster_config.py", line 51, in _load_config raise ConfigException("Service host/port is not set.") kubernetes.config.config_exception.ConfigException: Service host/port is not set.
