[0041] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] Please refer to Figure 1 , Figure 1 A flowchart illustrating a method for offline deployment of a Kubernetes cluster, as provided in an embodiment of the present invention. The method may include:

[0043] S100, obtain offline installation script information; the offline installation script information includes deployment installation packages and cluster compressed package images.

[0044] The execution subject in this embodiment is a terminal. This embodiment does not limit the type of terminal, as long as it can perform the file transfer resume operation after power failure. For example, it can be a general-purpose terminal or a dedicated terminal. The offline script information in this embodiment includes a deployment installation package (a binary installation package generated by kubekey) and a cluster compressed image (a tar archive image packaged from the kubesphere source cluster). The deployment installation package Kubekey in this embodiment provides a fast and efficient method for installing a Kubesphere (container management platform) cluster.

[0045] S101 creates OpenStack resources based on Terraform and predefined configuration information, and obtains the returned resource configuration file.

[0046] This embodiment uses Terraform (an orchestration tool for securely and efficiently building, modifying, and version-controlling infrastructure) related files from Kubespray (Kubespray is an open-source project from Google for deploying production-grade Kubernetes server clusters, integrating Ansible as a deployment tool) to create OpenStack resources according to predefined configuration information. Once the OpenStack resources are created, the resource configuration file is returned. OpenStack in this embodiment is an open-source cloud computing management platform project, a combination of a series of open-source software projects. OpenStack provides scalable and elastic cloud computing services for both private and public clouds. The project goal is to provide a simple-to-implement, scalable, rich, and standardized cloud computing management platform. OpenStack is a cloud platform management project, not a single piece of software. This project consists of several main components that perform specific tasks. OpenStack is an open-source project designed to provide software for the construction and management of public and private clouds. This embodiment does not limit the specific content of the predefined configuration information; any user-defined configuration information obtained is acceptable. For example, the configuration information may include IP address (Internet Protocol address), route name, private repository, and authentication information; or it may include pod (a pod is the smallest deployment unit in a Kubernetes system), authentication information, image information, and private repository. This embodiment does not limit the specific name of the resource configuration file. For example, the resource configuration file (tfstate file) may be named nginx-deployment.yaml; or the resource configuration file may be named nginx-service.yaml.

[0047] S102: Obtain the predefined image repository project and deploy the K8S cluster based on the offline installation script information, resource configuration files, and the predefined image repository project.

[0048] This embodiment does not limit the specific way the predefined image repository project is formed, as long as it is a predefined image repository project generated based on an image repository template. For example, a predefined image repository project can be generated based on an image repository template from Docker Hub (Docker Hub is used for source code management integration and also for build and testing tools to accelerate deployment cycles, reducing deployment cycles from days to minutes); or, a predefined image repository project can be generated based on an image repository template from GitHub (GitHub is a hosting platform for open source and private software projects, as it only supports Git as the sole version control format for hosting).

[0049] Furthermore, to quickly obtain a predefined image repository project, the process before obtaining the predefined image repository project may also include:

[0050] Generate a system configuration file using a system configuration template based on the cluster compressed image;

[0051] Generate an image repository based on the deployment installation package and system configuration files;

[0052] Generate image repository files using the image repository template;

[0053] The predefined image repository project is created based on the image repository and the image repository file.

[0054] This embodiment generates a system configuration file (config-sample.yaml file) from the cluster compressed image (kubesphere.tar.gz) using a system configuration template (config-sample.yaml.j2 template); generates an image repository based on the deployment package (the binary installation package generated by kubekey) and the system configuration file; generates an image repository file using the image repository template; and creates the predefined image repository project based on the image repository and the image repository file (create_project_harbor.sh file). This embodiment can directly generate a predefined image repository project using the cluster compressed image, system configuration template, and deployment package, eliminating the need for users to obtain a predefined image repository project according to the operation manual.

[0055] Furthermore, in order to deploy a Kubernetes cluster based on resource configuration files, deployment packages, and cluster compressed image images, after creating OpenStack resources based on Terraform and predefined configuration information and obtaining the returned resource configuration files, the following can also be included:

[0056] Send the resource configuration files, deployment packages, and cluster compressed image to the jump server to execute the deployment of the Kubernetes cluster.

[0057] This embodiment copies resource configuration files, deployment packages, and cluster compressed image images to a jump server to perform the deployment of a Kubernetes cluster. This embodiment does not limit the specific type or installation location of the jump server. For example, the jump server could be Puppet (a centralized configuration management system for Linux / Unix platforms, using its own Puppet description language); or it could be SaltStack (a centralized server infrastructure management platform with configuration management, remote execution, and monitoring functions); or it could be Ansible (an open-source automation platform and configuration management tool); or it could be Bastion (a container used for management). This embodiment does not limit the specific installation location of the jump server. The jump server can be installed on this terminal or on another terminal.

[0058] Furthermore, to configure the relevant parameters of the Kubernetes cluster, after obtaining the predefined image repository project and deploying the Kubernetes cluster based on the offline installation script information, resource configuration files, and the predefined image repository project, the following may also be included:

[0059] Use automated operation and maintenance tools to obtain the configuration files corresponding to the K8S cluster.

[0060] This embodiment does not limit the specific type of automated operation and maintenance tool, as long as it can obtain the configuration file corresponding to the Kubernetes cluster and modify the parameters. For example, the automated operation and maintenance tool could be Puppet (a centralized configuration management system for Linux / Unix platforms); or it could be Saltstack (an automated infrastructure management tool); or it could be Ansible (an open-source automation platform, a configuration management tool, and an automated operation and maintenance tool). After the Kubernetes cluster is deployed, when it is necessary to obtain and modify relevant configuration information, the automated operation and maintenance tool can be used.

[0061] Furthermore, in order to obtain log information generated during the deployment of the Kubernetes cluster in real time, the above-mentioned method for offline deployment of the Kubernetes cluster may also include:

[0062] Real-time logs generated during the deployment of a Kubernetes cluster can be displayed through remote procedure calls.

[0063] This embodiment does not limit the specific remote procedure call (RPC) framework used for the remote procedure call. For example, the RPC framework could be an RPC (Remote Procedure Call); or it could be the Dubbo remote procedure call service framework; or it could be gRPC (High-Performance Remote Procedure Call framework). This embodiment invokes the RPC framework to display real-time logs generated during the deployment of the Kubernetes cluster, thereby obtaining real-time logs generated during the deployment process and promptly identifying problems that arise during the deployment.

[0064] Furthermore, in order to obtain the deployment progress of the Kubernetes cluster in a timely manner, the above-mentioned method for offline deployment of the Kubernetes cluster may also include:

[0065] Monitor the deployment progress of the Kubernetes cluster and return a message indicating successful deployment.

[0066] This embodiment does not limit the specific entity monitoring the Kubernetes cluster, as long as the entity can reside within the device where the Kubernetes cluster is deployed offline, and is part of that device. For example, the entity monitoring the deployment progress of the Kubernetes cluster could be Prometheus (an open-source system monitoring and alerting system); or it could be a cluster manager, such as Spark (a standalone cluster manager, a simple Spark cluster manager that easily creates clusters based on Spark's own Master-Worker cluster); or it could be Hadoop YARN (Spark can integrate with Hadoop, using Yarn for resource scheduling). This embodiment utilizes the cluster manager to monitor the deployment progress of the Kubernetes cluster and returns a deployment success message, ensuring timely return of a deployment success message after deployment completion and guaranteeing the smooth execution of subsequent operations.

[0067] The offline deployment method for Kubernetes (K8S) clusters provided in this invention involves obtaining offline installation script information, including a deployment installation package and a cluster compressed image. OpenStack resources are created based on Terraform and predefined configuration information, resulting in a returned resource configuration file. A predefined image repository project is obtained, and the K8S cluster is deployed based on the offline installation script information, the resource configuration file, and the predefined image repository project. This invention uses Terraform in Kubespray to generate the resource configuration file. This is integrated with the cluster compressed image, combining the advantages of Kubespray's ability to generate clusters offline with the advantage of the cluster compressed image's ability to quickly install K8S clusters. K8S cluster deployment can be achieved simply by inputting predefined configuration information. Compared to existing technologies that require manual step-by-step deployment of K8S clusters according to installation files, the offline deployment method provided by this invention can call the offline installation script information to achieve one-click deployment of the K8S cluster. That is, installers only need to input predefined configuration information to achieve one-click deployment of the K8S cluster, greatly improving the deployment efficiency of the K8S cluster. Furthermore, embodiments of the present invention can invoke automated operation and maintenance tools, enabling timely acquisition of the configuration files corresponding to the K8S cluster and modification of parameters; furthermore, embodiments of the present invention can invoke a remote procedure call framework to display real-time logs generated during the deployment of the K8S cluster, realizing a log display service, and allowing for problem tracing based on the logs; furthermore, embodiments of the present invention can utilize the cluster manager to monitor the deployment progress of the K8S cluster and return a deployment success notification, enabling rapid acquisition of information on successful K8S cluster deployment and facilitating rapid commencement of subsequent work.

[0068] For a clearer understanding of this invention, please refer to the following details. Figure 2 , Figure 2The flowchart illustrates a method for offline deployment of a Kubernetes cluster, as provided in this embodiment of the invention. Specifically, it may include: obtaining kubesphere.tar.gz (cluster compressed image) and kk (deployment installation package); creating OpenStack resources based on Terraform and predefined configuration information, obtaining the returned tfstate file (resource configuration file); saving the tfstate file, kubesphere.tar.gz, and kk, and connecting to the bastion (jump host); and generating the config-sample.yaml file (system configuration template) by calling kubesphere.tar.gz and the config-sample.yaml.j2 template. The process involves: generating an image repository based on the kk and config-sample.yaml files; calling the create_project_harbor.sh.j2 template (image repository template) to generate the create_project_harbor.sh file (image repository file); generating a predefined image repository project based on the create_project_harbor.sh file and the image repository; deploying a K8S cluster with one click based on the tfstate file, the predefined image repository project, kubesphere.tar.gz, and kk; and outputting a terminal that supports kubectl commands (command line tool) and the K8S login URL (Uniform Resource Locator).
