How do I deploy Gradio app with Kubernetes?

Intermediate

This is my Gradio app’s repo.

I’m trying to deploy it with Docker Kubernetes. For that, I’ve tried 2 different YAML files. One is this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
      - name: nginx
        image: nginx:1.14.2
        ports:
        - containerPort: 80

and the other is this:

apiVersion: apps/v1
kind: Deployment
metadata:
  name: bb-demo
  namespace: default
spec:
  replicas: 1
  selector:
    matchLabels:
      bb: web
  template:
    metadata:
      labels:
        bb: web
    spec:
      containers:
      - name: bb-site
        image: getting-started
        imagePullPolicy: Never
---
apiVersion: v1
kind: Service
metadata:
  name: bb-entrypoint
  namespace: default
spec:
  type: NodePort
  selector:
    bb: web
  ports:
  - port: 3000
    targetPort: 3000
    nodePort: 30001

With both these yaml files, the command gets executed successfully:

>>> kubectl apply -f yaml_file_name.yaml
deployment.apps/app_name created
service/app-entrypoint created

However, when I check the deployments, I get 0 ready:

>>> kubectl get deployments
NAME               READY   UP-TO-DATE   AVAILABLE   AGE
layoutlm-demo      0/1     1            0           90s
nginx-deployment   3/3     3            3           13m

And when I check the services, I don’t get any external IPs:

kubectl get services             
NAME                  TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE
kubernetes            ClusterIP   10.96.0.1        <none>        443/TCP          20m
layoutlm-entrypoint   NodePort    10.100.255.103   <none>        3000:30001/TCP   10m
layoutlm-v2-demo      NodePort    10.101.117.217   <none>        8080:30000/TCP

Since I’m extremely new to Kubernetes (this is my first try in fact), I really have no clue about what the yaml file should contain. So, could anyone here guide me to the correct yaml file to use for this app?

Or, if one of these yaml files I’m using is correct, then could you point out what’s the error and how to fix it?
