Container cold transferring method and system

Abstract

The invention provides a container cold transferring method and system. The method comprises the steps of storing configuration parameter information of a source node container and the container state; copying a data volume loaded by the source node container to a target node; importing the source node container into the target node; modifying the configuration parameter information; creating a container through the modified configuration parameter information; setting the container state to be the stored container state. By transferring the source node container to the target node, firstly the data volume loaded by the source node container is copied to the target node, then by transferring the configuration parameter information and the state, it is guaranteed that data in the containerand data in the container data volume are not lost, therefore the problems that when a physical node in a cluster needs hardware upgrading or faces a possible error risk, the container in the currentnode needs to be transferred to another node, and the usability is poor are solved; the container cluster is conveniently managed, and by using a floating IP, it is guaranteed that the transferred IPaddress cannot be changed.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a container cold migration method and system. Background technique [0002] With the development of the Internet and container technology, almost all IT suppliers and cloud service providers have begun to adopt solutions based on container technology, and the portability of containers is particularly important. [0003] With the advent of Docker technology, developers can package their application and dependencies into a portable container, and then publish it to any popular Linux machine. The container can be regarded as the container of the software supply chain, which can encapsulate the operating environment, cache environment, database environment, etc. required by the application, and supports the operation of the application in the most concise way. It has the characteristics of small size and efficient operation. The image feature of the container makes this meth...

Problems solved by technology

[0005] The purpose of the present invention is to provide a container cold migration method and system, which aims to solve the problems that the container is easy to lose data, the file modification in the local storage cannot be restored, and the network status changes during the cold migration process of the container. Integrity and consistency of data in container root disks, container data volumes, etc.
