# This example demonstrate communication with a remote Kube cluster from a
# server outside of the cluster without kube client installed on it.
# The communication is secured with the use of Bearer token.
from kubernetes import client, config

# Define the barer token we are going to use to authenticate.
# See here to create the token:
# https://kubernetes.io/docs/tasks/access-application-cluster/access-cluster/
aToken = "XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX"
# Create a configuration object
aConfiguration = client.Configuration()
# Specify the endpoint of your Kube cluster
aConfiguration.host = "https://XXX.XXX.XXX.XXX:443"
# Security part.
# In this simple example we are not going to verify the SSL certificate of
# the remote cluster (for simplicity reason)
aConfiguration.verify_ssl = False
# Nevertheless if you want to do it you can with these 2 parameters
# configuration.verify_ssl=True
# ssl_ca_cert is the filepath to the file that contains the certificate.
# configuration.ssl_ca_cert="certificate"
