docker tomcat 日志时间时区不对

docker 启动时已经采用了-v /etc/localtime:/etc/localtime:ro来同步宿主机时间跟docker容器时间，但是发现docker 容器内Tomcat日志时间仍然不是宿主机时间，
检查下java环境的配置

java -XshowSettings

可以看到java配置

java时区.png

在宿主机时间正确的情况下
解决方案:修改docker容器的/etc/profile文件

......
export TZ='Asia/Shanghai'

添加环境变量，然后使用命令source /etc/profile使其生效

然后启动tomcat的时候会读取/etc/timzone来获取时区

docker exec -it tomcat bash
echo "Asia/Shanghai" > /etc/timezone
