Problems solved by technology

[0003] With the wide application of custom resource types, the types of resources in the cluster have become various. For operators who are not familiar with cluster resources, there is a risk of accidentally deleting key resources of the cluster and causing the cluster to hang up. Therefore, a resource deletion protection mechanism is needed. To ensure the security and stability of the cluster

Abstract

The invention belongs to the technical field of cloud computing, and provides a method for realizing container resource customized scheduling and deletion protection based on a Webhook technology, and the method can realize the following steps: automatically scheduling container resources to a specified node for creation, and ensuring that management side resources are not preempted when tenant side resources are created; protection annotations are added to the resources when the resource objects are created; when cluster key resources are deleted, whether the resources can be deleted or not is determined according to whether the protection characteristics are started or not, and therefore resource deletion protection is achieved, and the method has the advantages that container resource customized scheduling is achieved, and management side resources can be protected against being occupied by tenant side resources without manual modification; key resources in the cluster are subjected to deletion protection, and cluster unavailability caused by mistaken deletion of the key resources of the cluster is prevented; a tenant side is supported to specify a node of an installation container, and user-defined scheduling is met.

Description

Technical field [0001] This patent covers the field of cloud computing technology, especially a method of customizing scheduling and deletion protection of container resources based on Webhook technology. Background [0002] Kubernetes provides custom resource types and custom controllers to extend the functionality, and also provides dynamic admission control, that is, access control through webhooks, which are divided into two types: validating the nature of the admission webhook (Validating Admission Webhook) and modifying the nature of the admission webhook (Mutating AdmissionWebhook). The invocation principle of Webhook in Kubernetes is to first register an Enlighten Webhook (Validating / Mutating) with the Kubernetes cluster, and when the user's request reaches the Kubernetes Apiserver, Apiserver is based on the configuration of The DutatingWebhookConfiguration and the ValidatingWebhookConfigurat ion. First call The DutatingWebhookConfiguration to modify the user's requested ...
