Kubernetes - 为部署设置时区

Question

我需要部署一个具有欧洲/罗马时区的应用程序。

我应用了以下部署：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
  labels:
    app: myapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
        - name: myapp
          image: 10.166.23.73:5000/local/myapp:latest
          imagePullPolicy: Always
          ports:
            - containerPort: 8080
          env:
            - name: TZ
              value: Europe/Rome
          volumeMounts:
          - name: tz-rome
            mountPath: /etc/localtime
      volumes:
        - name: tz-rome
          hostPath:
            path: /usr/share/zoneinfo/Europe/Rome

但是，当我在 POD 中运行“日期”命令时，我没有得到“欧洲/罗马”时区...

上面的部署yaml有什么问题？

如果您删除 env 变量，那应该可以。例如：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp
  namespace: test-timezone
  labels:
    app: myapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
        - name: myapp
          image: busybox
          imagePullPolicy: Always
          command: [ "sleep", "10000" ]
          volumeMounts:
          - name: tz-rome
            mountPath: /etc/localtime
      volumes:
        - name: tz-rome
          hostPath:
            path: /usr/share/zoneinfo/Europe/Rome

输出：

/ # date

如果要使用TZ环境设置时区，则需要容器中的tzdata包，例如：

apiVersion: apps/v1
kind: Deployment
metadata:
  name: myapp3
  namespace: test-timezone
  labels:
    app: myapp
spec:
  replicas: 1
  selector:
    matchLabels:
      app: myapp
  template:
    metadata:
      labels:
        app: myapp
    spec:
      containers:
        - name: myapp
          image: nginx
          imagePullPolicy: Always
          command: [ "sleep", "10000" ]
          env:
            - name: TZ
              value: Europe/Rome

Nginx 里面有 tzdata 包：

root@myapp2-6f5bbdf56-nnx66:/# apt list --installed | grep tzdata

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

tzdata/now 2021a-1+deb11u2 all [installed,local]

root@myapp2-6f5bbdf56-nnx66:/# date
