Embodiment 1

[0066] Such as Figure 1-15 As shown, the method for implementing an Overlay multi-tenant CNI container network based on Open vSwitch provided in this embodiment may, but is not limited to, include the following steps.

[0067] S101. Install the CCS-SDN service program on each node node in the K8s cluster, wherein the K8s cluster is a cluster of versions above K8s 1.6 and runs Open vSwitch on each node node, and the CCS-SDN service program is A software-defined network protocol written based on the CCS integrated development environment.

[0068] In the step S101, the K8s cluster is a Kubernetes-based container cluster that builds a container multi-tenant network, such as figure 2 As shown, the multi-tenant container network production environment of the K8s cluster can include, but is not limited to, an external network, a management network, an IPMI network (Intelligent Platform Management Interface, an intelligent platform management interface), an SDN (Software Defined N...

Abstract

The invention relates to the technical field of multi-tenant networks, and discloses a method for realizing an Overlay multi-tenant CNI container network based on Open vSwitch. The invention providesa new method for solving the problem of multi-tenant two-layer network isolation of a container PaaS platform based on Kubernetes. According to the method, network isolation can be carried out among different tenants, and each tenant can only access his / her own network resources and cannot access network resources of other tenants, so that the problem of network isolation between the tenants and other tenant services is solved, the legitimate rights and interests of the tenants for their own service access are guaranteed, and malicious access of other tenants is prohibited.

Description

technical field [0001] The invention belongs to the technical field of multi-tenant networks, and in particular relates to a method for realizing an Overlay multi-tenant CNI container network based on Open vSwitch. Background technique [0002] Multi-tenancy is a kind of software architecture, which means that multiple or multiple groups of different users share a basic resource pool to realize the sharing of software and hardware resources. For an enterprise, the significance of a multi-tenant system is that everyone can share a system instead of splitting it into multiple subsystems for independent management, resulting in a waste of manpower and computing resources. The multi-tenant network is an inevitable requirement of the cloud computing data center network. According to the technical requirements of cloud computing resource virtualization, it virtualizes the network topology and links, and realizes the isolation and sharing of network resources according to the strat...
