The present embodiment is not limited to the type of the terminal, and may be any terminal as long as it can complete the operation of resuming the file transmission after the file is powered off in the present embodiment, and for example, the terminal may be a general-purpose terminal or a dedicated terminal. The offline script information in this embodiment includes a deployment installation package (binary installation package generated by kubbekey) and a cluster compression package mirror (tar package mirror packaged by kubbesphere source cluster). The deployment installation package Kubekey in this embodiment provides a method for quickly and efficiently installing a Kubesphere (container management platform) cluster.
S101, establishing Openstack resources according to the Terraform and predefined configuration information, and obtaining a returned resource configuration file.

The OpenStack in this embodiment is an open-source cloud computing management platform project, and is a combination of a series of software open-source projects, and the OpenStack can provide scalable and flexible cloud computing services for private clouds and public clouds. The project aims to provide a cloud computing management platform which is simple to implement, can be expanded in a large scale, is rich and has a unified standard. OpenStack is a cloud platform managed item, which is not software. The project is combined by several main components to complete specific work, and the OpenStack is an open source project aiming at providing software for the construction and management of public and private clouds. The embodiment does not limit the specific content of the predefined configuration information, as long as the configuration information defined by the user is acquired. For example, the configuration information may include an IP Address (Internet Protocol Address), a route name, private repository, authentication information, and the like; or the configuration information may include a pod (pod is the smallest unit of deployment in a k8s system), authentication information, mirroring information, private warehouse, and the like. This embodiment does not limit the specific name of the resource profile. For example, the name of the resource configuration file (tfstate file) is nginx-deployment. Yaml; or the name of the resource profile is nginx-service.
S102, acquiring a predefined mirror image warehouse project, and deploying the K8S cluster according to the offline installation script information, the resource configuration file and the predefined mirror image warehouse project.
The embodiment does not limit the specific forming manner of the predefined mirror image warehouse items, and the predefined mirror image warehouse items generated according to the mirror image warehouse template can be used. For example, predefined mirror warehouse items may be generated from mirror warehouse templates in a Docker Hub (Docker Hub is used for source code management integration, as well as for building and testing tools to accelerate deployment cycles, which decrease from days to minutes); alternatively, predefined mirror warehouse items may be generated from mirror warehouse templates in Github (GitHub is an open source and proprietary software project oriented hosting platform, since only Git is supported for hosting as the only version library format).
Further, in order to obtain the predefined mirror image warehouse item quickly, before the obtaining the predefined mirror image warehouse item, the method may further include:
generating a system configuration file by using a system configuration template according to the cluster compression package mirror image;

J2 template) according to a cluster compressed package image (kubsphere. Tar. Gz); generating a mirror image warehouse according to a deployment installation package (binary installation package generated by kubekey) and a system configuration file; generating a mirror image warehouse file by using a mirror image warehouse template; the predefined mirror repository item is created from the mirror repository and the mirror repository file (create _ project _ harbor. According to the embodiment, the predefined mirror image warehouse item can be directly generated by using the cluster compression package mirror image, the system configuration template and the deployment installation package, and a user does not need to obtain the predefined mirror image warehouse item according to an operation manual.
Further, in order to deploy the K8S cluster according to the resource configuration file, the deployment installation package, and the cluster compression package image, after the Openstack resource is created according to the terrafrorm and the predefined configuration information and the returned resource configuration file is obtained, the method may further include:

The embodiment copies the resource configuration file, deploys the installation package, and mirrors the cluster compression package to the springboard to perform the action of deploying the K8S cluster. The embodiment does not limit the specific kind and installation position of the trigger. For example, the springboard may be puppet (puppet is a centralized configuration management system under Linux/Unix platform, using its own puppet description language); or the jumper can also be a SaltStack (the SaltStack is a centralized management platform of a server infrastructure and has the functions of configuration management, remote execution, monitoring and the like); or the gangboard machine can also be an as-ible (the as-ible is an automatic platform for opening sources and is a configuration management tool); or the springboard machine can be a bag ion (a container used for management by the bag ion). This embodiment does not limit the specific mounting location of the trigger. The springboard machine can be arranged at the terminal or at the other terminal.

For example, the automated operation and maintenance tool may be Puppet (Puppet is a centralized configuration management system under Linux/Unix platform); or the automation operation and maintenance tool can also be Saltstack (SaltStack is an automation tool for infrastructure management); or the automation operation and maintenance tool can also be an enterprise (the enterprise is an opening automation platform, a configuration management tool and an automation operation and maintenance tool). After the deployment of the K8S cluster is completed, when the related configuration information needs to be acquired and modified, an automated operation and maintenance tool may be used for processing.
Further, in order to obtain log information generated by deploying the K8S cluster in real time, the method for deploying the K8S cluster offline may further include:
and displaying the real-time log generated in the K8S cluster deploying process through remote process call.

The embodiment does not limit the specific main body for monitoring the K8S cluster, as long as the main body can be located inside the device for deploying the K8S cluster offline, and is used as a part of the device for deploying the K8S cluster offline. For example, the main body for monitoring the deployment progress of the K8S cluster may be Prometheus (an open source system monitoring and alarm system); or the main body for monitoring the deployment progress of the K8S cluster may also be a cluster manager, for example, the cluster manager may be a Spark (independent cluster manager (standard), a simple Spark cluster manager, which is easy to establish a cluster and is based on a Master-Worker cluster of the Spark itself); or, the cluster manager may also be a Hadoop YARN (Spark may be integrated with Hadoop, and resource scheduling is performed by using YARN). In the embodiment, the cluster manager is used for monitoring the deployment progress of the K8S cluster and returning the prompt information of successful deployment, so that the prompt information of successful deployment can be timely returned after the deployment is finished, and the smooth execution of the subsequent operation is ensured.
