解决 docker 容器时间与本地时间不一致

解决 docker 容器时间与本地时间不一致

第一种方法：启动时进行映射

运行 docker run 添加 -v /etc/localtime:/etc/localtime 选项，如下：
docker run -d -p 8080:80 -v /etc/localtime:/etc/localtime nginx

重点就是： -v /etc/localtime:/etc/localtime:ro

第二种：复制时区信息到容器

• 如果本机时区正确直接：

docker cp /etc/localtime nginx:/etc/localtime

docker cp /etc/localtime [容器ID或名字]:/etc/localtime

• 如果本机时区不正确：

docker cp /usr/share/zoneinfo/Asia/Shanghai nginx:/etc/localtime

自己习得心得

• 进入容器

root@server105:~# docker exec -it Open_APIser /bin/bash

• 查看容器内时间

root@4fc9ec0a5fae:/APIServer# date
Thu Feb  4 06:08:12 UTC 2021         # 关键字UTC

• 查找关键字

root@4fc9ec0a5fae:/APIServer# find / -name UTC     
/usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/Etc/UTC
/usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/UTC

• 复制路径查看目录下内容

root@4fc9ec0a5fae:/APIServer# ls /usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/Etc/   
GMT    GMT+10  GMT+2  GMT+5  GMT+8  GMT-1   GMT-12  GMT-2  GMT-5  GMT-8  Greenwich  Universal
GMT+0  GMT+11  GMT+3  GMT+6  GMT+9  GMT-10  GMT-13  GMT-3  GMT-6  GMT-9  UCT        Zulu
GMT+1  GMT+12  GMT+4  GMT+7  GMT-0  GMT-11  GMT-14  GMT-4  GMT-7  GMT0   UTC

root@4fc9ec0a5fae:/APIServer# ls /usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/     # 找到关键Asia(亚洲)
Africa      CET      Egypt    GMT+0      Iran       MST7MDT  Poland     UTC          zone.tab

Brazil      EST5EDT  GMT      Indian     MST        Pacific  US         tzdata.zi

• 找到上海时区

root@4fc9ec0a5fae:/APIServer# ls /usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/Asia/Shanghai 

• 将上海时区文件创建软链接到/etc/目录下

root@4fc9ec0a5fae:/APIServer# ln -s /usr/local/lib/python3.8/dist-packages/pytz/zoneinfo/Asia/Shanghai /etc/localtime

• 再次查看时间

root@4fc9ec0a5fae:/APIServer# date
Thu Feb  4 14:09:44 CST 2021        # 发现时间已经更新

启动时就指定参数

• 启动命令中加参数

[root@localhost node_test]# docker run -itd --name test02 -e "TZ=Asia/Shanghai" node:latest

• 查看结果

[root@localhost node_test]# docker exec -it test02  date
Tue Jun  8 11:45:53 CST 2021
