+description: How to deploy heartbeat in multiple instances by k8s
+---
+
+## Solutions
+
+Following the next tutorial, you can use Heartbeat in the k8s environment more conveniently.
+
+### Step 1: create a namespace
+
+If you don't have heartbeat namespace, create one.
+
+```shell
+kubectl create namespace heartbeat
+```
+
+### Step 2: create pv and pvc
+
+#### 2.1 Create pv
+
+Create file `k8s-persistent-volume.yaml` and run `kubectl apply -f k8s-persistent-volume.yaml` to deploy pv.
+
+- k8s-persistent-volume.yaml
+
+You can use this command to create file `k8s-persistent-volume.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: v1
+kind: PersistentVolume
+metadata:
+  name: pv
+  namespace: heartbeat
+spec:
+  capacity:
+    storage: 200Mi
+  accessModes:
+    - ReadWriteMany
+  storageClassName: heartbeat
+  hostPath:
+    path: /data' > k8s-persistent-volume.yaml
+```
+
+Then you can use this command to deploy pv.
+
+```shell
+kubectl apply -f k8s-persistent-volume.yaml
+```
+
+You can use `kubectl get pv pv` to confirm whether the pv is created successfully.
+
+```shell
+kubectl get pv pv
+```
+
+#### 2.2 Create pvc
+
+Create file `k8s-persistent-volume-claim.yaml` and run `kubectl apply -f k8s-persistent-volume-claim.yaml` to deploy pvc.
+
+- k8s-persistent-volume-claim.yaml
+
+You can use this command to create file `k8s-persistent-volume-claim.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: v1
+kind: PersistentVolumeClaim
+metadata:
+  name: pvc
+  namespace: heartbeat
+spec:
+  accessModes:
+    - ReadWriteMany
+  resources:
+    requests:
+      storage: 200Mi
+  storageClassName: heartbeat' > k8s-persistent-volume-claim.yaml
+```
+
+Then you can use this command to deploy pvc.
+
+```shell
+kubectl apply -f k8s-persistent-volume-claim.yaml
+```
+
+You can use `kubectl get pvc -n heartbeat` to confirm whether the pvc is created successfully.
+
+```shell
+kubectl get pvc -n heartbeat
+```
+
+### Step 3: deploy backend
+
+#### 3.1 Create backend service
+
+Create file `k8s-backend-service.yaml` and run `kubectl apply -f k8s-backend-service.yaml` to create backend service.
+
+- k8s-backend-service.yaml
+
+You can use this command to create file `k8s-backend-service.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: v1
+kind: Service
+metadata:
+  namespace: heartbeat
+  name: backend
+  labels:
+    app: backend
+spec:
+  selector:
+    app: backend
+  ports:
+    - protocol: TCP
+      port: 4322
+      targetPort: 4322' > k8s-backend-service.yaml
+```
+
+Then you can use this command to deploy backend service.
+
+```shell
+kubectl apply -f k8s-backend-service.yaml
+```
+
+You can use `kubectl get services -n heartbeat` to confirm whether the backend service is created successfully.
+
+```shell
+kubectl get services -n heartbeat
+```
+
+#### 3.2 Deploy backend pods
+
+Create `k8s-backend-deployment.yaml` and run `kubectl apply -f k8s-backend-deployment.yaml` to deploy backend deployment.
+
+- k8s-backend-deployment.yaml
+
+You can use this command to create file `k8s-backend-deployment.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: apps/v1
+kind: Deployment
+metadata:
+  namespace: heartbeat
+  name: backend
+  labels:
+    app: backend
+spec:
+  replicas: 3
+  selector:
+    matchLabels:
+      app: backend
+  template:
+    metadata:
+      labels:
+        app: backend
+    spec:
+      initContainers:
+        - name: backend-init
+          image: busybox
+          securityContext:
+            runAsUser: 0
+          volumeMounts:
+            - name: volumes
+              mountPath: /app/output
+          command: ["sh", "-c", "chown -R 999:999 /app/output"]
+      containers:
+        - name: backend
+          image: ghcr.io/au-heartbeat/heartbeat_backend:latest
+          volumeMounts:
+            - name: volumes
+              mountPath: /app/output
+      volumes:
+        - name: volumes
+          persistentVolumeClaim:
+            claimName: pvc' > k8s-backend-deployment.yaml
+```
+
+Then you can use this command to deploy backend deployment.
+
+```shell
+kubectl apply -f k8s-backend-deployment.yaml
+```
+
+You can use `kubectl get pods -n heartbeat` to confirm whether the backend pods is created successfully.
+
+```shell
+kubectl get pods -n heartbeat
+```
+
+### Step 4: deploy frontend
+
+#### 4.1 Create frontend service
+
+Create `k8s-frontend-service.yaml` and run `kubectl apply -f k8s-frontend-service.yaml` to create frontend service.
+
+- k8s-frontend-service.yaml
+
+You can use this command to create file `k8s-frontend-service.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: v1
+kind: Service
+metadata:
+  namespace: heartbeat
+  name: frontend
+  labels:
+    app: frontend
+spec:
+  selector:
+    app: frontend
+  ports:
+    - protocol: TCP
+      port: 4321
+      targetPort: 80
+  type: LoadBalancer' > k8s-frontend-service.yaml
+```
+
+Then you can use this command to deploy frontend service.
+
+```shell
+kubectl apply -f k8s-frontend-service.yaml
+```
+
+You can use `kubectl get services -n heartbeat` to confirm whether the frontend service is created successfully.
+
+```shell
+kubectl get services -n heartbeat
+```
+
+#### 4.2 Deploy frontend pods
+
+Create `k8s-frontend-deployment.yaml` and run `kubectl apply -f k8s-frontend-deployment.yaml` to deploy frontend deployment.
+
+- k8s-frontend-deployment.yaml
+
+You can use this command to create file `k8s-frontend-deployment.yaml` with filled in content.
+
+```shell
+echo 'apiVersion: apps/v1
+kind: Deployment
+metadata:
+  namespace: heartbeat
+  name: frontend
+  labels:
+    app: frontend
+spec:
+  replicas: 1
+  selector:
+    matchLabels:
+      app: frontend
+  template:
+    metadata:
+      labels:
+        app: frontend
+    spec:
+      containers:
+        - name: frontend
+          image: ghcr.io/au-heartbeat/heartbeat_frontend:latest' > k8s-frontend-deployment.yaml
+```
+
+Then you can use this command to deploy frontend service.
+
+```shell
+kubectl apply -f k8s-frontend-deployment.yaml
+```
+
+You can use `kubectl get pods -n heartbeat` to confirm whether the frontend pods is created successfully.
+
+```shell
+kubectl get pods -n heartbeat
+```
