I get this

Error parsing yaml file:
mapping values are not allowed here
  in \"/home/antonio/Desktop/ATI/cl         


        

Answer 1

Another cause is wrong indentation which means trying to create the wrong objects. I've just fixed one in a Kubernetes Ingress definition:

Wrong

- path: / 
    backend: 
      serviceName: <service_name> 
      servicePort: <port> 

Correct

- path: /
  backend:
    serviceName: <service_name>
    servicePort: <port>
