Server expansion method and device

Abstract

The embodiment of the invention provides a server capacity expansion method and device. The server capacity expansion method includes the steps that the resource occupation rates of all Docker servers are detected; according to the resource occupation rates of all the Docker servers, a target Docker server is determined; a first extension instruction is sent to the target Docker server to allow the target Docker server to establish a first Docker container according to the first extension instruction; the corresponding relationship between the IP address of the first Docker container and the domain name of the target Docker server is sent to a domain name server. By means of the embodiment of the server capacity expansion method and device, the resource utilization rates of the Docker servers with the low resource utilization rates are increased, and the resource utilization rates on the multiple Docker servers tend to be balanced.

Description

Technical field [0001] The embodiment of the present invention relates to the field of communication technology, and in particular to a method and device for server expansion. Background technique [0002] Docker is an open source application container engine. After Docker is installed on the physical host, multiple containers can be carried on the basis of Docker. Multiple containers are isolated from each other. Multiple containers share the operating system of the physical host. Each container can be placed And execute different applications. [0003] The physical host installed with Docker containers is called the Docker server. A Docker server can be installed with multiple Docker containers, but the number of Docker containers installed on each Docker server is fixed, because the user terminal accesses each Docker container at a different frequency , Resulting in frequent access to Docker containers on some Docker servers, and low access frequency of Docker containers on som...

[0003] The physical host with Docker containers installed is called a Docker server. A Docker server can have multiple Docker containers installed, but the number of Docker containers installed on each Docker server is fixed, because the frequency of user terminals accessing each Docker container is different. , causing the Docker containers on some Docker servers to be accessed frequently, and the Docker containers on some Docker servers to be accessed less frequently, resulting in unbalanced resource utilization on each Docker server
