K8s mongoldb yaml

以下是一个K8s部署MongoDB的YAML示例：

apiVersion: v1
kind: Service
metadata:
  name: mongodb
  labels:
    app: mongodb
spec:
  ports:
  - port: 27017
    targetPort: 27017
  selector:
    app: mongodb
---
apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: mongodb
spec:
  serviceName: mongodb
  replicas: 3
  selector:
    matchLabels:
      app: mongodb
  template:
    metadata:
      labels:
        app: mongodb
    spec:
      containers:
      - name: mongodb
        image: mongo
        ports:
        - containerPort: 27017
        volumeMounts:
        - name: mongodb-data
          mountPath: /data/db
  volumeClaimTemplates:
  - metadata:
      name: mongodb-data
    spec:
      accessModes: [ "ReadWriteOnce" ]
      resources:
        requests:
          storage: 1Gi

该YAML文件定义了一个名为mongodb的Service和StatefulSet，其中StatefulSet包含3个MongoDB实例。每个实例都有一个1GB的持久卷，用于存储数据。
