Editor to share with you why to use docker, I hope you will learn something after reading this article, let's discuss it together!

A product from development to launch, from the operating system, to the running environment, and then to the application configuration. As a collaboration between developers and operators, we need to care about a lot of things, which is a problem that many Internet companies have to face, especially after the iteration of various versions, the compatibility of different versions of the environment is a test for operation and maintenance personnel.

The reason why Docker is growing so rapidly is also because it gives a standardized solution to it.

The configuration of the environment is so troublesome that it is necessary to do it all over again with another machine, which is laborious and time-consuming. Many people think, can you fundamentally solve the problem, the software can be installed with the environment? In other words, when installing, copy the original environment exactly the same. Developers can use Docker to eliminate the problem that collaborative coding is "working on my machine."

Before configuring an application running environment on the server, you need to install all kinds of software, such as java/tomcat/mysql/jdbc driver and so on. I won't say much about how troublesome it is to install and configure these things. It can't cross-platform yet. If we install these environments on windows, we will have to reinstall them when we get to linux. And even if not across the operating system, for another operating system of the server, to transplant the application is also very troublesome.

Traditionally, it is believed that the results produced after software coding development / testing are completed, even if the program or binary bytecode that can be compiled and executed, and so on. In order for these programs to be executed smoothly, the development team also has to prepare a complete deployment file so that the operation and maintenance team can deploy the application. The developer needs to clearly tell the operation and maintenance team all the configuration files and all software environments to be used. However, even so, deployment failures often occur. The design of Docker image enables Docker to break the past concept of "program is application". Except for the core of the operating system, the system environment needed to run the application is packaged from top to bottom to achieve the seamless running of the application across platforms.

After reading this article, I believe you have a certain understanding of "Why use docker". If you want to know more about it, you are welcome to follow the industry information channel. Thank you for your reading!
