[0044] 102. Receive a cluster configuration file.

[0045] The cluster configuration file contains the Kubernetes service configuration information corresponding to the deployment server node and the Kubernetes service configuration information corresponding to each other server node.

[0046] In an embodiment of the present application, after the staff inputs the offline deployment compressed package into the deployment server node, they also need to edit the cluster configuration file corresponding to the target server cluster according to business needs, and input the cluster configuration file corresponding to the target server cluster into the deployment server node. At this time, the deployment server node can receive the cluster configuration file corresponding to the target server cluster.

[0047] 103. Execute the environment initialization script to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file.

[0048] The role of the environment initialization script is to control the deployment server node to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file.

[0049] In an embodiment of the present application, after receiving the cluster configuration file corresponding to the target server cluster, the deployment server node can execute the environment initialization script, so that the environment initialization script controls the deployment server node to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file, so that the deployment server node and each other server node meet the conditions for deploying the Kubernetes service.

Because, in the embodiment of the present application, after the staff inputs the offline deployment compressed package and the cluster configuration file corresponding to the target server cluster into the deployment server node, the deployment server node can automatically deploy the Kubernetes service on the deployment server node and each other server node, so that there is no need for the staff to manually perform a series of cumbersome operations such as installing kubelet and configuring the network, thereby effectively improving the efficiency of deploying the Kubernetes cluster.

[0054] To explain in more detail below, the present application embodiment provides another Kubernetes cluster deployment method, which is applied to the deployment server node in the target server cluster, as shown in the following example: Figure 2 As shown, the method includes:

[0055] 201. Receive an offline deployment compressed package and decompress the offline deployment compressed package.

[0056] The offline deployment compressed package includes an environment initialization script, a first deployment script, a preset deployment tool, a Docker image repository, an offline resource library, a second deployment script, a ceph-csi-rbd plug-in, and a helm tool.

[0057] Among them, the preset deployment tool is an RKE deployment tool with a built-in Cephadm deployment tool; among them, the Docker image repository contains multiple Docker images, and the offline resource library contains multiple Rpm packages.

[0060] Among them, the cluster configuration file contains Kubernetes service configuration information corresponding to the deployment server node, Kubernetes service configuration information corresponding to each other server node, Ceph service configuration information corresponding to the deployment server node, and Ceph service configuration information corresponding to each other server node.

[0061] In an embodiment of the present application, after the staff inputs the offline deployment compressed package into the deployment server node, they also need to edit the cluster configuration file corresponding to the target server cluster according to business needs, and input the cluster configuration file corresponding to the target server cluster into the deployment server node. At this time, the deployment server node can receive the cluster configuration file corresponding to the target server cluster.

[0062] 203. Execute the environment initialization script to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file.

[0063] In an embodiment of the present application, after receiving the cluster configuration file corresponding to the target server cluster, the deployment server node can execute the environment initialization script, so that the environment initialization script controls the deployment server node to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file, so that the deployment server node and each other server node meet the conditions for deploying the Kubernetes service.

[0064] Specifically, in this step, the deployment server node executes the environment initialization script so that the environment initialization script controls the deployment server node to perform environment initialization processing on the deployment server node and each other server node based on the cluster configuration file. The specific process is:

[0065] Among them, the Kubernetes service configuration information corresponding to each other server node contained in the cluster configuration file records the Docker image information corresponding to each other server node; wherein, the Docker image information corresponding to any other server node can be but is not limited to: the unique identifier corresponding to the Docker image required by the other server node.

[0066] Execute the environment initialization script so that the initialization script controls the deployment server node to perform the following operations:

[0067] (1) Perform confidentiality-free processing on each other server node so that the deployment server node can access each other server node without confidentiality;

[0068] (2) Install the Docker image repository and offline resource library into the local storage space of the deployment server node;

[0069] (3) Based on the cluster configuration file, the Docker image repository and the offline resource library, multiple Rpm packages are installed into the local storage space of each other server node, and multiple Docker images corresponding to each other server node are installed into the local storage space of each other server node, that is, firstly, multiple Docker images corresponding to each other server node are obtained from the Docker image repository according to the Docker image information corresponding to each other server node, and then, the multiple Docker images corresponding to each other server node are installed into the local storage space of each other server node according to the Docker image information corresponding to each other server node, and after obtaining multiple Rpm packages from the offline resource library, the multiple Rpm packages are respectively installed into the local storage space of each other server node;

[0070] (4) Turn off the firewall of the deployment server node and the firewall of each other server node to prevent the firewall of the deployment server node and the firewall of each other server node from affecting the deployment of Kubernetes services on the deployment server node.

[0071] 204. Execute a first deployment script to deploy the Kubernetes service on the deployment server node and on each other server node based on a preset deployment tool and a cluster configuration file.

[0072] In an embodiment of the present application, after the deployment server node performs environmental initialization processing on the deployment server node and each other server node, the deployment server node can execute the first deployment script, so that the first deployment script controls the deployment server node to deploy the Kubernetes service on the deployment server node based on the preset deployment tool and the cluster configuration file, and deploys the Kubernetes service on each other server node respectively, thereby realizing the deployment of the target server cluster as a Kubernetes cluster.

[0073] Specifically, in this step, the deployment server node executes the first deployment script so that the first deployment script controls the deployment server node to deploy the Kubernetes service on the deployment server node based on the preset deployment tool and the cluster configuration file, and the specific process of deploying the Kubernetes service on each other server node is as follows:

[0074] Among them, the Kubernetes service configuration information corresponding to the deployment server node contained in the cluster configuration file records the Docker image information corresponding to the deployment server node. The Docker image information corresponding to the deployment server node can be but is not limited to: the unique identifier corresponding to the Docker image required by the deployment server node.

[0075] Execute the first deployment script so that the first deployment script controls the deployment server node to perform the following operations:

Execute the second deployment script to deploy the Ceph service on the deployment server node and on each other server node based on the preset deployment tool and the cluster configuration file; deploy the ceph-csi-rbd plug-in on the deployment server node and on each other server node based on the helm tool.
