Container cloud platform multi-tenant building method, media, device based on Kubernetes and OpenStack

Abstract

A container cloud platform multi-tenant building method based on Kubernetes and OpenStack includes steps: Container cloud platform responding to requests to create tenant, getting a list of tenants for OpenStack, the associated tenant selected by the user, creating a container tenant associated with the associated tenant, assigning the cluster selected by the user to the container tenant, in response to a request from the user, creating a partition request, getting a list of tenant routers for OpenStack and User-selected associated router, specifying Service CIDR and Pod CIDR according to theID range of the associated router, OpenStack creating a network belonging to the associated router and service subnet and pod subnet belonging to the network, and the container cloud platform creatingtenant partitions. The invention realizes the multi-tenant construction of the container cloud platform, and the tenant can use the corresponding Openstack tenant resources to ensure the resource isolation among different tenants.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a multi-tenant construction method, medium and equipment based on Kubernetes and OpenStack container cloud platform. Background technique [0002] Kubernetes is Google's open source container cluster management system. It provides functions such as application deployment, maintenance, and expansion mechanisms. Using Kubernetes can easily manage cross-machine running containerized applications. Its main functions include using Docker to package, instantiate, and Run; run in a cluster and manage cross-machine containers; solve the communication problem between Docker cross-machine containers; Kubernetes' self-healing mechanism makes the container cluster always run in the state expected by the user. Native Kubernetes does not have the concept of tenants and multi-tenants, but only the concept of namespaces. The existing technology is based on the realization of mult...

AI Technical Summary

Problems solved by technology

Native Kubernetes does not have the concept of tenants and multi-tenants, but only the concept of namespaces. The existing technology is based on the realization of multi-tenants based on namespaces. A namespace is represented as a tenant, and this tenant cannot use other namespaces or resources of other clusters, or A tenant owns a Kubernetes cluster, and tenants cannot share the same Kubernetes cluster, and the tenant and multi-tenant functions are not really realized

Under the current situation, Kubernetes cannot solve the following problems: how to ensure resource isolation between different tenants and prevent mutual access; how to solve the reallocation of computing resources under tenants; how to implement access control within tenants
