jbvm_operator.py

# This code creates a K8S Operator which will populate an object of kind 'JBVM' with two additional fields: 
# - cmdbname
# - deploystatus
# Run it with: "kopf run jbvm_operator.py --verbose"

# Use the following command to test: 
# "kubectl get jbvms -o custom-columns=NAME:.metadata.name,CMDBNAME:.spec.cmdbname,DEPLOYMENT:.spec.deploystatus"

# Define the handler function for the operator.

    # Get the name of the custom resource.
    name = body['metadata']['name']
