There is an 8 hour difference between the docker installation of mysql and the host.

Recently, I used docker to build a mysql container. When I started it, I found that the date inside was eight hours different from the host machine. At first, I thought it was a time zone problem of mysql, but later I found out that it was a time problem in the docker container.

Enter the host and docker and use the date command to check:

This is due to:

The host uses the CST time zone, and CST should refer to (China Shanghai Time, East Eighth District Time)
The container uses the UTC time zone, and UTC should refer to (Coordinated Universal Time, standard time)

Solution:

Because I have already started the container, I use the method of copying from the host machine to the inside of the container. If you have not run the container, it is best to mount the time file when you create the container.

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

Restart:

docker restart mysql
