Three major docker components: container and docker1. containers are another core concept of Docker. Simply put, containers are one or more applications that run independently and Their runtime environments.

A few days ago encountered such a business scenario, the database runs in the Docker, the Docker city is UTC so it is 8 hours away from the Beijing time.

Very distressed, First I change the host's time zone to CST Beijing
