Validating Error on deployment in Kubernetes - spring-boot

Question

I have tried to deploy the producer-service app with MySQL database in the Kubernetes cluster. When i try to deploy producer app then the following validation error has thrown.
error: error validating "producer-deployment.yml": error validating data: apiVersion not set; if you choose to ignore these errors, turn validation off with --validate=false
producer-deployment.yml

i have tried to find the error or typo within the config file but still, couldn't. What is wrong with the producer-deployment.yml file

Answer 1

Multiple issues:
It would be apiVersion: v1 not apiVerion: v1 in the Service
wrong Spec.ports formation of Service. As nodePort, port, targetPort and protocol are under the ports as a list but your did wrong formation.
your service yaml should be like below:
apiVersion: v1
kind: Service
metadata:
name: producer-app
labels:
name: producer-app
spec:
ports:
- nodePort: 30163
port: 9090
targetPort: 9090
protocol: TCP
selector:
app: producer-app
type: NodePort
So your overall yaml should be:
apiVersion: v1
kind: Service
metadata:
name: producer-app
labels:
name: producer-app
spec:
ports:
- nodePort: 30163
port: 9090
targetPort: 9090
protocol: TCP
selector:
app: producer-app
type: NodePort

Answer 2

Please change the first line in producer-deployment.yml. Letter s is missing.
From
apiVerion: v1
To
apiVersion: v1

Answer 3

There is a typo in the first line: "apiVerion" should be "apiVersion".

Answer 4

Your first error(there are more than 1) just point you to the place where you should start your investigation from..
error validating data: apiVersion not set;
As you know, each object in kubernetes has its own apiVersion.
Check Understanding Kubernetes Objects, especially Required Fields part:
In the .yaml file for the Kubernetes object you want to create, you'll
need to set values for the following fields:
apiVersion - Which version of the Kubernetes API you're using to
create this object
kind - What kind of object you want to create
metadata - Data that helps uniquely identify the object, including a
name string, UID, and optional namespace
spec - What state you desire
for the object The precise format of the object spec is different for
every Kubernetes object, and contains nested fields specific to that
object.
The Kubernetes API Reference can help you find the spec format
for all of the objects you can create using Kubernetes.
You can check Latest 1.20 API here
These values are mandatory and you wont be able to create object without them. So please, next time read more carefully errors you receive.
