container Cloud-platform multi-cluster building method, media and device based on Kubernetes and OpenStack

Abstract

A container Cloud-platform multi-cluster building method based on Kubernets and OpenStackcomprises that step of establishing a control cluster in the container cloud platform, defining a cluster API through the control cluster CRD, and creating a cluster controller and a node resource pool in the controller cluster; controlling the cluster to receive the cluster operation request and modify the cluster CR record sent by the user, The cluster controller using list- Watch mechanism to check cluster CR records and resource changes, delete and add user clusters according to resource changes, delete and add nodes, and the cluster controller updating cluster status, controllingthe cluster to receive the cross-cluster operation request sent by the user, the cluster controller judging whether thecross-cluster operation request corresponds to the cluster API or not, if yes, forwarding the cross-cluster operation request to the corresponding cluster for processing, otherwise, processing the cross-cluster operation request. The invention also relates to a storage medium and an electronic device. The invention realizes the construction of multiple clusters and multiple tenants of the container cloud platform, uniformly manages multiple clusters, and can share the same cluster among tenants.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a multi-cluster construction method, medium and equipment based on Kubernetes and OpenStack container cloud platforms. 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 works on a single cluster, and cannot achieve unified management of multiple clusters, such as creation and deletion at the cluster level, addition a...
