This article focuses on "how to solve the problem of 8 hours difference between docker container and host". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn how to solve the problem of 8 hours difference between docker container and host.

When deploying with docker-compose, the output log and related events are checked and output, resulting in an 8-hour difference between the event and the reality.

Troubleshoot problems:

1. Check the host time:

# View time dateWed Sep 29 11:12:44 CST 202 check time zone date-RWed, 29 Sep 2021 11:13:34 + 0800

two。 Enter the container to view the time

# View all containers docker ps-a # enter container docker eec-it [container ID] / bin/bash# view time date

The host time seen at this time is the same as that of the docker container. At this time, all kinds of Baidu finally know that it is the problem of timezone.

Linux time:

Container time:

Reason: the host has set the time zone, but the Docker container has not, resulting in an 8-hour difference between the two

CST should mean (China Shanghai Time, East eighth District time)

UTC should mean (Coordinated Universal Time, standard time)

So, the difference between these two times should actually be eight hours.

Therefore, the time zones of the two must be unified.

Solution:

1.docker-compose configure volume mount

Volumes:-/ usr/share/zoneinfo/Asia/Shanghai:/etc/localtime

2.Dockerfile runs commands and outputs corresponding time zones to timezone

RUN echo "Asia/shanghai" > / etc/timezone RUN cp / usr/share/zoneinfo/Asia/Shanghai / etc/localtime

3. Delete the container and rerun

# Delete docker rm [Container ID] # launch docker-compose-f [File name] up-d

Summary: the problem of / etc/timezone in the container caused by the time difference check for 2 hours can be set to the appropriate time zone.
