What are the differences between Docker and virtual machine
This article mainly introduces "what are the differences between Docker and virtual machine". In daily operation, I believe many people have doubts about the difference between Docker and virtual machine. I have consulted all kinds of materials and sorted out simple and easy-to-use operation methods. I hope it will be helpful for you to answer the question of "what is the difference between Docker and virtual machine"! Next, please follow the editor to study!
1. What are Docker?1.1 and Docker open source projects
Docker is a cloud open source project based on GE language, and its main goal is "bulid,Ship and run any app,Anywhere", that is, through the management of the life cycle of application components, such as encapsulation, distribution, deployment, operation, etc., to achieve "once package, run everywhere" at the application component level. Docker provides a "one-stop" solution for application development and deployment. Docker allows developers to package their applications and dependencies into a lightweight, portable container and publish them to any popular Linux machine.
1.2.The LInux container technology
The foundation of Docker engine is Linux container technology. What is container technology? The container effectively divides resources managed by a single operating system into isolated groups to better balance conflicting resource usage requirements between isolated groups.
2. Why use Docker?
Docker can efficiently build applications and package applications through containers by simply launching the required containers on the new server. Saves a lot of time and reduces the risk of problems in the deployment process.
There are also the following advantages in the development and operation and maintenance process:
Faster delivery and deployment
More efficient use of resources
Easier migration and expansion
Simpler update management
3. Comparison between docker and virtual machine.
Comparison of characteristics between docker container technology and traditional virtual machine technology:
At this point, the study on "what is the difference between Docker and virtual machine" is over. I hope to be able to solve your doubts.
