The word "if" as used herein may be interpreted as "at … …" or "at … …" or "responsive to a determination", depending on the context.

First, terms related to one or more embodiments of the present application will be explained.

k8s: kubernetes, abbreviated as K8s, is an abbreviation that replaces the 8 characters "ubennete" in the middle of a name with 8. Is an open source for managing containerized applications on multiple hosts in a cloud platform, and the goal of Kubernetes is to make deploying containerized applications simple and efficient (powerful), which provides a mechanism for application deployment, planning, updating, and maintenance.

A container: a container is a portable software unit that can consolidate applications and all their dependencies into one software package that is not limited by the underlying host operating system.

Dragonfly: is a file distribution and mirror image acceleration system based on P2P technology.

The distributed cloud is a cloud computing mode for deploying cloud services to different geographic positions as required and providing unified management capability. In distributed clouds, although service deployment is decentralized and possible in various regions, the requirements for management are concentrated. Kubernetes have become a standard of cloud environments, and a distributed cloud platform needs to be capable of supporting deployment and management of various types of Kubernetes clusters in multiple ways, and providing capabilities of unified authentication, partition management, unified access, unified configuration and the like on the distributed cloud platform, so that users can manage and access the environments of the distributed cloud as if the users are running locally.

In the production practice of Kubernetes cluster environments, smaller container images can quickly deploy a boot. When the mirror image of the application reaches more than several GB, downloading the mirror image on the node usually consumes a great amount of time, even if the project like Dramonfly is used for improving the distribution efficiency of the mirror image of the container by introducing the P2P network, the user still has to wait for the mirror image data to be completely downloaded to the local place and then can create the container of the user, in this case, the time for pulling the mirror image consumes the bottleneck point of the maximum quick service pull (the extreme case can occupy more than 95% of the total duration, the service starting speed is in the second level, and the mirror image is pulled in the minute level), so the mirror image preheating capability is very important.

However, the current image preheating mode only focuses on the host and the determined image to be preheated, and the following scenarios are not used: firstly, in a distributed cloud scene, clients are used together by multi-cloud multi-k 8s clusters, but the current preheating scheme is aimed at a single cluster and cannot carry out efficient mirror image preheating on a plurality of clusters; further, the environments (which may include environments with various dimensions, such as products, projects, namespaces, tenants, users, etc.) of the client in the distributed cloud multi-k 8s cluster are all relevant, and the current mirror image preset cannot embody the relationship between the environments, for example, the relationship between the renter and the tenant; and many times the name of the mirror to be preheated is not known in advance, for example: when the client performs mirror image deployment on the a-environment of the A-cluster, the b-environment related to the a-environment cannot be determined, and therefore the b-environment cannot be preheated in advance based on the mirror image of the a-environment of the A-cluster.

In the distributed cloud scene, the user can directly preheat the direct designated mirror images of a plurality of cluster dimensions, and can also mutually learn and preheat the related images in clusters or among cross-cluster environments so as to improve the speed of pulling up business application in a plurality of scenes. In the distributed cloud scene, the scheme of the application can carry out mirror image preheating for a single cluster and can also carry out mirror image preheating for a plurality of clusters; the mirror image can be preheated in a correlation learning mode through a multidimensional environment, so that the service starting speed is remarkably improved in some use scenes of the distributed cloud.

In the present application, a method for preheating and pulling an image file is provided, and the present application relates to a preheating and pulling device for an image file, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.

The mirror image preheating configuration information corresponding to each container cluster identifier is determined in the resource configuration information by the container control cluster, and then each mirror image preheating configuration information is issued to the corresponding service container cluster, so that the distribution efficiency of the mirror image preheating configuration information is improved; and the preheating pulling task of issuing mirror image files to a plurality of service container clusters is realized by utilizing the container control clusters, so that the preheating pulling efficiency of the service container clusters to the container mirror image files can be improved.

Specifically, the resource configuration information comprises one, two or more container cluster identifiers; the resource configuration information comprises mirror image preheating configuration information corresponding to each container cluster identifier; after the resource configuration information is determined in the container mirror image preheating instruction, the container control cluster analyzes the container cluster identification in the resource configuration information and the mirror image preheating configuration information corresponding to the container cluster identification so as to distribute the mirror image preheating configuration information to the service container clusters corresponding to the container cluster identification.

In practical application, because the mirror image files among the service container clusters may have the same content, the association relationship among the clusters can be determined, and the clusters needing mirror image preheating can be determined according to the association relationship.

Specifically, the method for determining at least one container cluster identifier according to the resource configuration information may include:

determining at least one initial container cluster identifier according to the resource configuration information;

and determining each initial container cluster identifier and each associated container cluster identifier as a container cluster identifier.

The initial container cluster identifier refers to a container cluster identifier obtained by analyzing resource configuration information; the associated container cluster identifier refers to a container cluster identifier with an association relationship with the initial container cluster identifier; in practical application, the associated container cluster identifier may be consistent or inconsistent with the container cluster identifier parsed in the resource configuration information; in the case where there is no correspondence between the associated container cluster identity and the container cluster identity parsed from the resource configuration information, the associated container cluster identity may be retrieved from a container cluster relationship table based on the initial container cluster identity.

Specifically, analyzing the resource configuration information to obtain one, two or more initial container cluster identifiers; searching an associated container cluster identifier corresponding to the initial container cluster identifier in a container cluster table which is created in advance according to the initial container cluster identifier; and taking each initial container cluster identifier and each associated container cluster identifier as container cluster identifiers.

In practical application, before determining the associated container cluster identifier corresponding to each initial container cluster identifier, the method further comprises:

determining an associated service container cluster corresponding to each service container cluster;

A cluster association relationship between the business container cluster and the associated business container cluster is created.

Wherein, the service container cluster refers to a cluster formed by service nodes; the associated service container cluster refers to a container cluster with an association relationship with nodes in the service container cluster; the cluster association relationship refers to a mapping relationship between service container clusters, for example, if service container cluster a, service container cluster B, and service container cluster C each contain tenant nodes, then the service container cluster a associated service cluster may be service container cluster B and service container cluster C.

Specifically, determining a service container cluster and an associated service container cluster of the service container cluster; and determining a cluster association relation based on the association relation between the service container clusters and the associated service container clusters, determining a container cluster identifier of the service container clusters and an associated container cluster identifier of the associated container clusters, and recording the container cluster identifier and the associated container cluster identifier based on the cluster association relation to obtain a container cluster relation table.

The method comprises the steps of determining at least one container cluster identifier according to resource configuration information, and generating mirror image preheating configuration information corresponding to each container cluster identifier, so that the resource configuration information is divided, and the mirror image preheating configuration information is conveniently distributed to corresponding service container clusters.

Step 206: and sending the mirror image preheating configuration information to the service container clusters corresponding to the container cluster identifiers so that the service container clusters preheat and pull the container mirror image file based on the mirror image preheating configuration information.

The container mirror image file is a file for pre-heating and pulling to the memory to create a container.

Specifically, under the condition that the initial container cluster identifiers are not provided with the corresponding associated container cluster identifiers, any initial container cluster identifier is determined to be used as a target initial container cluster identifier; determining a target business container cluster corresponding to the target initial container cluster identifier; and sending the target mirror image preheating configuration information corresponding to the target initial container cluster identifier to the target service container cluster.

In a specific embodiment of the present application, container cluster identifiers 1, 2 and 3 are obtained by analyzing resource configuration information; resolving mirror image preheating configuration information corresponding to each container cluster identifier in the resource configuration information based on the container cluster identifiers 1, 2 and 3; and sending the image preheating configuration information corresponding to each image preheating identifier to the container cluster corresponding to each image preheating identifier.

The process of issuing the mirror image preheating configuration information is that no associated container cluster identification exists; in practical application, the process of issuing the mirror image preheating configuration information with the associated container cluster identifier is as follows, and specifically, the method for sending each mirror image preheating configuration information to the service container cluster corresponding to each container cluster identifier may include:

Determining a target initial container cluster identifier and at least one target associated container cluster identifier corresponding to the target initial container cluster identifier, wherein the target initial container cluster identifier is any one of the initial container cluster identifiers;
