Embodiment Construction

[0050] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0051] Cloud computing resources usually use a management platform (for example, an open source cloud computing management platform OpenStack) to manage multiple resources in a unified manner and provide them to multiple tenants at the same time. The open source project Kubernetes (referred to as K8s) based on OpenStack is currently one of the most widely used container cluster management systems. It allows enterprises to use the cloud computing resources of the cluster as if they were using a computer, improving the use of computer resources. Efficiency, which solves many...

Abstract

The invention relates to a container network management system. The system comprises a network management module and at least one container cluster, the container cluster comprises a plurality of computing nodes, and a container network interface plug-in and a resource object are deployed on each computing node. Wherein the network management module divides a plurality of IP address pools according to the IP address of each computing node; and each computing node calls a container network interface plug-in to determine a target IP address corresponding to the resource object from a plurality of IP address pools according to the container configuration file of the resource object. In the system, the network architecture of the container cluster is deployed through the container network interface plug-in, and the network mode in each container cluster is unified. Besides, the address pool is divided in advance through the network management module, isolation of the IP resources and isolation of the network area are achieved under application of the tenants, and meanwhile, when the resource objects are restarted or newly built, the target IP address can be rapidly and accurately obtained through the address pool divided in advance.

Description

technical field [0001] The present application relates to the technical field of computer network and cloud computing, in particular to a container network management system. Background technique [0002] Kubernetes (k8s for short) is a distributed architecture solution based on container technology. Usually, k8s itself does not provide network functions, but network plug-ins provide corresponding network solutions. For example, the network plug-in can be a container network interface (Container Network Interface, CNI) plug-in, through which different network solutions can be integrated for k8s. [0003] Taking solving the problem of cross-host communication as an example, in related technologies, when CNI solves the problem of cross-host communication, according to the dependency relationship with the host machine network, the implementation modes of the network solution include but not limited to: overlay mode, routing mode and underlay mode. Among them, the underlay mode...
