Xiao Bai asked a question, on a server (such as 4-core 16G), use docker to run a web application and start only one container. I understand that docker is a process, so will there be any performance problems for the application in the docker container? Can you make full use of the server hardware?
Docker is generally not as good as direct use of machines, generally has little impact, and is better than virtual machines.
If you have extreme requirements for performance and the machines are limited, it is better not to use them.
