[0035] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are some embodiments but not all embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0036] In the existing various cloud computing platforms, service product components are diversified and complicated, the traditional cloud platform deployment and upgrade process is time-consuming and prone to errors, and manual intervention is required, which is particularly inconvenient in a large-scale cluster environment. Although the existing automation tools have been improved, there is still room for improvement, especially in terms of rapid response to service changes and guaranteeing business continuity. And various service products often require different deployment and upgrade methods, which reflects the orchestratability and compatibility of the framework. Therefore, the ssh channel-based automatic service rapid deployment and upgrade framework can be more widely applied. Only by providing information files conforming to the deployment and upgrade templates can automatic deployment and upgrade be realized, greatly improving the use efficiency, reducing manual operation, effectively reducing exceptions and avoiding risks. And the framework structure can effectively accommodate different needs of various component deployment and upgrade, improving the deployment and upgrade speed.

[0037] Through the definition of the serviceTask self-defined deployment task core template, the compatibility of various deployment components and deployment tasks is realized, and the deployment methods with different implementation manners but the same execution process are achieved. The depence dependency item is used to solve the dependency relationship between components and components, and the dependency method is defined, which can better solve the abnormal problems caused by the coupling between components. The site intervention effectively provides a collection of basic environment information, and can be distinguished in detail corresponding to different cloud platforms. The nodeSelector node selector can be used to customize the running node in detail, and the multi-node selector can be used to refine the granularity and more accurately realize the deployment action allocation. The cluster mode guarantees the high availability of the product environment, ensures the stability of the environment, and provides a high-quality customer experience. The key points in the technical solutions will be explained in detail as follows.

[0038] 1) site: site, configured with basic information of the environment (cluster, node, network configuration, etc.), required chart collection.

[0039] 2)serviceTask: service item, defines a component, in the text it is actually a deployment or upgrade requirement, which belongs to the custom yaml file of the service product. The framework will implement the corresponding operation on the cloud platform environment according to the file.

[0040] 3)type: defines the operation type, deployment or upgrade

[0041] 4)depence: dependency, because a component may depend on one or more other components, it is necessary to detect the health of the dependent component during deployment and upgrade, in the text, dependency includes runtime dependency and deployment dependency.

[0042] 5)cluster: cluster, k8s cluster, contains one or more nodes (node).

[0043] 6)nodeSelector: node selector, its value is the label of the node, and the node information that meets the requirements is obtained through this parameter.

[0044] 7)command: specific operation on cluster or node resources.

[0045] serviceTask template:

[0046]

[0047]

[0048] serviceTask execution logic, as shown in Figure 2

[0049] 1) First, read the deployment and upgrade requirement template to get the deployment or upgrade requirement to be executed.

[0050] 2) According to the requirement, a series of internal methods are used to generate the deployment or upgrade file to be executed.

[0051] 3) Read the site configuration information of the corresponding environment to filter out the cluster nodes that meet the execution conditions.

[0052] 4) Use the certificate to remotely access the cluster nodes to be run from the master node to detect the running state of the dependent components.

[0053] 5) Automatically upload the execution file from the master node to the node to be run.

[0054] 6) Automatically run the execution file and detect the execution completion result.

[0055] Design idea:

[0056] 1. Generation of deployment and upgrade items ​

[0057] The program will preset some deployment, upgrade items for general public scenario deployment and upgrade. For example, node system vulnerability upgrade, automation tool deployment, etc.

[0058] Users can create the required deployment and upgrade request according to their needs. The created detection items need to contain name (component name), cluster, command, and optional nodeSelect content. Among them, nodeSelect represents one or a kind of node resource, supports using null for full node matching; command represents the operation on this resource or this resource, supports using the program built-in parameters to get simple cluster environment information.

[0059] Technical key points:

[0060] 1) command condition is rich and expandable. command not only supports custom deployment and upgrade items. It also supports using the program's built-in upgrade items, including but not limited to, node time synchronization, node label modification, system tool upgrade, etc., and supports subsequent expansion.

[0061] 2) serviceTask is a custom template, product parties can freely configure according to their own product needs. As long as the deployment or upgrade needs that meet the template format can be realized, which greatly reduces the work of configuring the upgrade and deployment steps once for each new component in the past. Using automation to achieve, reduces the risk of human intervention errors, and also greatly improves the deployment and upgrade efficiency.

[0062] 3) Through the reasonable combination of cluster, nodeSelect, command, the user can flexibly define the required deployment and upgrade scene, the demand coverage is extensive, the deployment and upgrade command access is diversified, etc. For example, you can use "empty" to match all clusters and nodes, you can use the program's built-in conditions, etc.

[0063] 2. Execution of deployment and upgrade items

[0064] After receiving the user request, first, according to the site information of the current execution environment, the resource information of the current environment is obtained, including but not limited to, node name, network information, label, belonging cluster, node role, etc. Then the basic detection of the current cluster or node environment is carried out, including but not limited to, whether the cluster node running state is normal, whether the network information configuration is accurate, whether the cluster node quantity is matched, etc. After the basic detection, the user-provided custom deployment upgrade file is loaded, the cluster node information to be executed is obtained according to the cluster, nodeSelect and other parameters, the user-defined corresponding deployment upgrade method is generated according to the command parameter, then the runtime dependency and deployment dependency of the user-specified node are detected, and according to the operation type, the deployment or upgrade operation to be performed is judged, the custom deployment upgrade command is executed, and the result is obtained.

[0065] 3. Judgment of deployment upgrade item

[0066] After the detection of the dependency is executed, if the state is normal, the corresponding deployment upgrade operation is performed. After the execution file is executed, the execution result detection is carried out in multiple ways, the return value judgment execution result can be used. The result detection can also be carried out through the custom command in serviceTask; the health interface detection can also be carried out through curl or other commands. Flexible custom judgment makes the access deployment upgrade detection condition diversified, the custom and default two detection modes can provide more convenient user experience.

[0067] The above only describes the preferred embodiments of the present application, which are used to illustrate the technical solutions of the present application, and are not used to limit the protection scope of the present application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the present application is included in the protection scope of the present application.
