I am trying to access Kubernetes cluster deployed Spring Boot microservices and trying to test the REST API. I configured the node port method in my deployment scripts. But when I am trying to access using Postman tool, I am only getting the response that "Could not get any response".

I configured the service.yaml script like the following structure,

apiVersion: v1
kind: Service
metadata:
  name: my-service
spec:
  type: NodePort
  ports:
    - port: 7100
      targetPort: 7100
      protocol: TCP
      name: http
      nodePort: 31007
 selector:
      app: my-deployment

My deployment.yaml like the following ,

apiVersion: apps/v1
kind: Deployment
metadata:
  name: my-deployment
  labels:
    app: my-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: my-deployment
  template:
    metadata:
      labels:
        app: my-deployment
      annotations: 
        date: "+%H:%M:%S %d/%m/%y"
    spec:
      imagePullSecrets:
        - name: "regcred"
      containers:
       - name: my-deployment-container
         image: spacestudymilletech010/spacestudysecurityauthcontrol:latest
         imagePullPolicy: Always
         ports:
            - name: http
              containerPort: 8065
              protocol: TCP
      tolerations:
      - key: "dedicated-app"
        operator: "Equal"
        value: "my-dedi-app-a"
        effect: "NoSchedule"

When I am taking kubectl describe service, output is like the following,

And I am trying to access my deployed api Like the following way,

  http://<my-cluster-Worker-NodeIP-Address:31007/<my-deployed-ReST-API-end-point>

Updates

When I am running the kubectl describe pod command for my deployment I am getting the response like the following,

I am getting the event message from describe pod command like 0/2 nodes are available: 2 node(s) had taints that the pod didn't tolerate. as shown above.

When I am running kubectl get nodes command , I am getting like the following,

NAME           STATUS   ROLES    AGE   VERSION
mildevkub020   Ready    master   5d    v1.17.0
mildevkub040   Ready    master   5d    v1.17.0

Where have I gone wrong for service access?
