IP monitoring and recycling system and method based on network namespace management and control

Abstract

The invention discloses an IP monitoring and recycling system and method based on network namespace management and control. The system comprises an IP distribution management server, an IP distribution management agent, a plurality of container groups, a container engine, a cluster API server and a database; the container groups are connected with the container engine to realize data interaction;the IP distribution management server is connected with the container engine, the cluster API server and the database to realize data interaction, and the IP distribution management agent is connectedwith the container engine and the cluster API server to perform monitoring and confirmation; the corresponding relationship between the container and the network namespace can be obtained by monitoring the network namespace; after the container is deleted, the network namespace which is not used any more in data recovery can be monitored, it is guaranteed that the IP of the deleted container group is certainly released, abnormal leakage is avoided, and it is guaranteed that the IP of the deleted container group does not conflict with the IP allocated subsequently.

Description

technical field [0001] The present invention relates to the network management function of a Kubernetes-based container cloud platform, and in particular to an IP monitoring and recovery system and method based on network namespace management and control. Background technique [0002] The network of the container cloud platform is the cornerstone of the platform. Container group IP address management is the basis for applications to provide external services. In the process of operation and maintenance management, IP allocation, management, and monitoring are not only related to the external services of the cluster, but also related to security. Realization of functions such as auditing; [0003] In Kubernetes-based container cloud platform solutions, although Kubernetes has native CNI network support such as MacVlan, it also provides default IPAM options, for example: [0004] DHCP (Dynamic Host Configuration Protocol): As the name implies, it means dynamic allocation, i...

AI Technical Summary

Problems solved by technology

[0011] This solution solves the IP management problem of the customer's MacVlan container cloud platform, and focuses on the problems caused by IP error recovery. This mechanism can effectively improve the effect of operation and maintenance automation. IP management is essential in production or test development environments. It is a very heavy task, requiring operation and maintenance personnel to accurately grasp the IP allocation and changes in the entire environment, and spend a lot of time dealing with various problems caused by IP management confusion or IP conflicts. The container platform itself will run into There are tens of thousands of container groups, whose number is far greater than the IP management of virtual machines. IPAM monitors the container network namespace in the platform, which can effectively ensure that platform IPs will not conflict, thereby enhancing the degree of customer operation and maintenance automation and reducing manual operations. , to solve the defects caused by the existing technology
