<h3>问题3：pod中的时间分区和宿主机的不同</h3>
<p>解决问题方法一：配置环境变量</p>

kind: Deployment
metadata:
spec:
template:
spec:
containers:
env:
- name: TZ #添加该环境变量
value: Asia/Shanghai</pre>
</div>
<p>解决问题方法二：挂载时间文件</p>
<div class="cnblogs_Highlighter">
<pre class="brush:bash;gutter:true;">apiVersion: apps/v1
kind: Deployment
metadata:
spec:
template:
spec:
containers:
volumeMounts:
- name: time-mount
mountPath: /etc/localtime #将Asia/Shanghai挂载的容器中

- name: time-mount
hostPath:
path: /usr/share/zoneinfo/Asia/Shanghai #也可以使用软链：/etc/localtime</pre>
</div>
