Multi-tenant construction method, medium and equipment based on kubernetes and openstack container cloud platform

Abstract

The present invention provides a multi-tenant construction method based on Kubernetes and OpenStack container cloud platform, including the steps: the container cloud platform responds to the tenant creation request, obtains the tenant list of OpenStack, the associated tenant selected by the user, creates the container tenant associated with the associated tenant, and selects the user Assign the cluster to the container tenant, respond to the partition creation request sent by the user, obtain the tenant router list of OpenStack, the associated router selected by the user, specify the Service CIDR and Pod CIDR according to the ID range of the associated router, and OpenStack creates a network belonging to the associated router and a network belonging to the associated router. The Service subnet and Pod subnet of the network, and the container cloud platform creates tenant partitions. The present invention realizes the multi-tenant construction of the container cloud platform, and the tenants can use their corresponding Openstack tenant resources to ensure 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
