Validating Error on deployment in Kubernetes

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

apiVerion: 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

apiVersion: apps/v1

                name: db-config
                key: host
            - name: DB_NAME
              valueFrom:
               configMapKeyRef:
                name: db-config
                key: name
            - name: DB_USERNAME
              valueFrom:

Please change the first line in producer-deployment.yml. Letter s is missing.

From

apiVerion: v1

To

apiVersion: v1

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

apiVersion: apps/v1
kind: Deployment
metadata:
  name: producer-app
spec:
  selector:
    matchLabels:
      app: producer-app
  replicas: 3
  template:
    metadata:
      labels:
        app: producer-app
    spec:
      containers:
        - name: producer
          image: producer:1.0
          ports:
            - containerPort: 9090
          env:
            - name: DB_HOST
              valueFrom:
                configMapKeyRef:
                  name: db-config
                  key: host
            - name: DB_NAME
              valueFrom:
                configMapKeyRef:
                  name: db-config
                  key: name
            - name: DB_USERNAME
              valueFrom:
                secretKeyRef:
                  name: db-user
                  key: username
            - name: DB_PASSWORD
              valueFrom:
                secretKeyRef:
                  name: db-user
                  key: password

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

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.
