Response method and device of access request and storage medium

Abstract

The invention discloses an access request response method and device, and a storage medium, and the method comprises the steps: obtaining a to-be-allocated extranet segment corresponding to a container cloud, the to-be-allocated extranet segment comprising a plurality of to-be-allocated extranet IP addresses; according to a node IP address of a target node, determining a target network segment located in the same network segment as the node IP address in the external network segments to be allocated; the external network IP address to be distributed in the target network segment is distributed to the target node; and under the condition that a first POD in the target node receives an access request sent by an external network, selecting a target IP address from a plurality of external network IP addresses to be allocated in the target network segment, and responding to the access request through the target IP address, by adopting the technical scheme, the problem that the IP is allocated to a main network of the POD by using macvlan or ipvlan cni is solved, and the access efficiency is improved. And IP address waste can be caused.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a method and device for responding to an access request, and a storage medium. Background technique [0002] The network of the container cloud platform is the cornerstone of the platform, and the POD is the basis for applications to provide external services. In the existing Kubernetes-native container cloud network solutions, the general solutions are as follows: [0003] 1) Use the EIP method, such as figure 1 Shown: [0004] Public cloud vendors such as Alibaba Cloud and AWS all support elastic public network IP (EIP), which can be used to deal with situations where pods need independent public network addresses in some scenarios. Taking Alibaba Cloud as an example, to mount an independent public network EIP for a Pod, you only need to modify the relevant permissions of the network plug-in terway, and then specify the EIP for the Pod in the template: k8s.aliyun.com / POD-wi...

AI Technical Summary

Problems solved by technology

[0011] Embodiments of the present invention provide a response method and device for an access request, and a storage medium, so as to at least solve the problems in related technologies, such as using macvlan or ipvlan cni to assign IP to the main network of POD, which will cause waste of IP addresses and the like
