# 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

def main():

# 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"

aConfiguration.api_key = {"authorization": "Bearer " + aToken}

# Create a ApiClient with our config

aApiClient = client.ApiClient(aConfiguration)

# Do calls
