This article will explain in detail how to install and use Docker under Linux. The editor thinks it is very practical, so I share it with you for reference. I hope you can get something after reading this article.

Docker is the most popular open source application container engine that allows developers to package their applications and dependency packages into a portable image, publish them to any popular Linux machine, and virtualize them. Containers are fully sandboxed and will not have any interface with each other.
