设置容器时区
更新时间：2025-02-13
本文介绍如何为容器配置时区，以此来保证容器中的时间与所处环境的时间一致，避免时区错误导致的时间一致性和准确性等问题。
配置示例
- 创建一个ConfigMap，导入/usr/share/zoneinfo/目录下您需要的时区
YAML
1kubectl create configmap tz --from-file=/usr/share/zoneinfo/Asia/Shanghai- 创建配置时区的应用
YAML
1kubectl apply -f timezone-demo.yamltimezone-demo.yaml内容示例如下：
YAML
1apiVersion: apps/v1
2kind: Deployment
3metadata:
4 annotations:
5 deployment.kubernetes.io/revision: "1"
6 labels:
7 name: pod-test
8 name: pod-test
9 namespace: default
10spec:
11 replicas: 1
12 selector:
13 matchLabels:
14 name: pod-test
15 template:
16 metadata:
17 creationTimestamp: null
18 labels:
19 name: pod-test
20 spec:
21 containers:
22 - image: registry.baidubce.com/glen-centos/centos:centos7
23 imagePullPolicy: IfNotPresent
24 name: pod-test
25 resources:
26 limits:
27 cpu: 250m
28 memory: 500Mi
29 requests:
30 cpu: 250m
31 memory: 500Mi
32 terminationMessagePath: /dev/termination-log
33 terminationMessagePolicy: File
34 volumeMounts:
35 - name: tz
36 mountPath: /etc/localtime # 挂载路径
37 subPath: Shanghai # 请根据您的ConfigMap替换
38 dnsPolicy: Default
39 volumes:
40 - name: tz
41 configMap: # 挂载ConfigMap
42 name: Shanghai
43 tolerations:
44 - effect: NoSchedule
45 key: virtual-kubelet.io/provider
46 operator: Equal
47 value: baidu
48 nodeSelector:
49 type: virtual-kubelet验证结果
- 提交上述yaml，登录到容器内，验证时区是否设置成功。命令提交前根据实际Pod名称替换
。
YAML
1kubectl exec -it <pod-name> -- sh- 查询容器时区
YAML
1date -R如果返回的时间与设置的时区信息对应，则表示设置成功。返回示例如下：
