MongoDB in Kubernetes within GCP

I'm trying to deploy mongodb on my k8s cluster as mongodb is my db of choice. To do that I've config files (very similar to what I did with postgress few weeks ago).

Here's mongo's deployment k8s object:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: panel-admin-mongo-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: panel-admin-mongo
  template:
    metadata:
      labels:
        component: panel-admin-mongo
    spec:
      volumes:
        - name: panel-admin-mongo-storage
          persistentVolumeClaim:
            claimName: database-persistent-volume-claim
      containers:
        - name: panel-admin-mongo
          image: mongo
          ports:
            - containerPort: 27017
          volumeMounts:
            - name: panel-admin-mongo-storage
              mountPath: /data/db

In order to get into the pod I made a service:

apiVersion: v1
kind: Service
metadata:
  name: panel-admin-mongo-cluster-ip-service
spec:
  type: ClusterIP
  selector:
    component: panel-admin-mongo
  ports:
    - port: 27017
      targetPort: 27017

And of cource I need a PVC as well:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: database-persistent-volume-claim
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 2Gi

In order to get to the db from my server I used server deployment object:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: panel-admin-api-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      component: panel-admin-api
  template:
    metadata:
      labels:
        component: panel-admin-api
    spec:
      containers:
        - name: panel-admin-api
          image: my-image
          ports:
            - containerPort: 3001
          env:
            - name: MONGO_URL 
              value: panel-admin-mongo-cluster-ip-service // This is important
      imagePullSecrets:
        - name: gcr-json-key

But for some reason when I'm booting up all containers with kubectl apply command my server says: MongoDB :: connection error: MongoParseError: Invalid connection string

Can I deploy it like that (as it was possible with postgress)? Or what am I missing here?

Use mongodb:// in front of your panel-admin-mongo-cluster-ip-service

So it should look like this: mongodb://panel-admin-mongo-cluster-ip-service
