I am trying to deploy keycloak on a kubernetes cluster and when I am trying to login to admin console it is returning “Cookie not found”. Even under application cookie I don’t see any cookies. Below is my deployment

apiVersion: apps/v1
kind: Deployment
metadata:
  name: keycloak-deployment

    app: keycloak

  replicas: 1

              key: DB_USER
              name: postgres-credentials
        - name: KEYCLOAK_ADMIN
          valueFrom:
            secretKeyRef:
              name: keycloak-credentials
              key: KEYCLOAK_ADMIN
        - name: KEYCLOAK_ADMIN_PASSWORD
          valueFrom:
            secretKeyRef:
              name: keycloak-credentials
              key: KEYCLOAK_ADMIN_PASSWORD
        - name: image.debug
          value: "true"
        ports:
        - containerPort: 8080

The same deployment I do on minikube and access the service via minikube service keycloak-service --url it is showing cookie and also letting me login to admin console.
