Postgres 用户未创建 Kubernetes

Question

我有以下 YAML 文件用于创建 postgres 服务器实例

kind: Deployment
apiVersion: apps/v1beta1
metadata: 
 name: spring-demo-db
 labels: 
  app: spring-demo-application
spec: 
 replicas: 1
 selector: 
  matchLabels: 
   app: spring-demo-db
 template: 
  metadata: 
   creationTimestamp: null
   labels: 
    app: spring-demo-db
  spec: 
   containers: 
    - name: spring-demo-db
      image: postgres:10.4
      ports: 
      - name: spring-demo-db
        containerPort: 5432
        protocol: TCP
      env: 
      - name: POSTGRES_PASSWORD
        value: "springdemo"
      - name: POSTGRES_USER
        value: "springdemo"
      - name: POSTGRES_DB
        value: "springdemo"
      volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgres-storage
      terminationMessagePath: /dev/termination-log
      terminationMessagePolicy: File
      imagePullPolicy: IfNotPresent
   volumes: 
    - name: "postgres-storage"
      persistentVolumeClaim: 
       claimName: spring-demo-pv-claim   
   restartPolicy: Always

但是当 ssh 进入容器时用户 springdemo 没有创建。我整天都在挣扎。这可能是什么问题

谁能帮帮我？

你没有提到你正在运行什么命令以及你遇到了什么错误，所以我在这里猜测，但试试这个：

kind: Deployment
apiVersion: apps/v1beta1
metadata: 
 name: spring-demo-db
 labels: 
  app: spring-demo-application
spec: 
 replicas: 1
 selector: 
  matchLabels: 
   app: spring-demo-db
 template: 
  metadata: 
   creationTimestamp: null
   labels: 
    app: spring-demo-db
  spec: 
   containers: 
    - name: spring-demo-db
      image: postgres:10.4
      ports: 
      - name: spring-demo-db
        containerPort: 5432
        protocol: TCP
      env: 
      - name: POSTGRES_USER
        value: "springdemo"
      - name: POSTGRES_DB
        value: "springdemo"
      - name: POSTGRES_PASSWORD
        value: "springdemo"
      volumeMounts:
            - mountPath: /var/lib/postgresql/data
              name: postgres-storage
      terminationMessagePath: /dev/termination-log
      terminationMessagePolicy: File
      imagePullPolicy: IfNotPresent
   volumes: 
    - name: "postgres-storage"
      persistentVolumeClaim: 
       claimName: spring-demo-pv-claim   
   restartPolicy: Always

但如果它不起作用，只需使用Helm chart，因为除其他问题外，您以不安全的方式传递密码，这是一个坏主意。
