[Solved] The date in the docker container is inconsistent with the centos system time

centos time zone time

• First of all, make sure your Linux system time is what you need, you can use timedatectlto view
• The Linux system generally defaults to time zone 0. UTCWhen we use it, we can change the time zone to Dongba District as neededCST
• If there is a discrepancy between the Linux system time and Beijing time, it must be dealt with first. You can refer to [Solved] CentOS7 and other linux systems have incorrect time zone time and display an error of 8 hours.

Time in docker container

• The system in the docker container is also Linux, and the default time zone is 0UTC
• As before, you also need to modify the time zone and time, but the docker container has operations such as closing, deleting, and restarting. It is not recommended to enter the modification after starting the container
• It can be set in the docker-compose configuration file or the docker startup command, and it can be consistent with the host system
• Here is the docker-compose configuration writing method
• Mainly divided into 2 points, one is to specify localtime, and the other is to set the time zone

    volumes:
      - /etc/localtime:/etc/localtime
    environment:
      - TZ=Asia/Shanghai
