k8s快速创建MongoDB

1.创建MongoDB pvc文件

如果不需要持久存储可以忽略

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: mongodb-data
  namespace: t1-zdbl
spec:
  storageClassName: nfs-client  #这里使用的存储类
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 30G

2.创建deployment文件

apiVersion: apps/v1
kind: Deployment
metadata:
  name: t1-zdbl-mongodb
  namespace: t1-zdbl
spec:
  replicas: 1
  selector:
    matchLabels:
      app: t1-zdbl-mongodb
  template:
    metadata:
      labels:
        app: t1-zdbl-mongodb
    spec:
      containers:
        - name: zdbl-mongodb
          image: mongo:4.4.15
          env:
            - name: MONGO_INITDB_ROOT_USERNAME #注意我设置了用户名和密码
              value: root
            - name: MONGO_INITDB_ROOT_PASSWORD
              value: 'qiD303d1Q$8Yq^Sj'
          ports:
            - containerPort: 27017
          volumeMounts:
            - name: mongodb-data
              mountPath: /data/db
      volumes:
        - name: mongodb-data
          persistentVolumeClaim:
            claimName: mongodb-data

3.创建svc文件

apiVersion: v1
kind: Service
metadata:
  labels:
    app: t1-zdbl-mongodb
  name: t1-zdbl-mongodb
  namespace: t1-zdbl
spec:
  type: NodePort  
  ports:
    - name: mongo
      port: 27017
      protocol: TCP
      targetPort: 27017
  selector:
    app: t1-zdbl-mongodb

应用以上文件即可
