Description

Technical Field

[0001] The present invention relates to the technical field of cluster service deployment, and in particular to a method for deploying cluster services based on incubated middleware instances. Background Art

[0002] In the scenario of cluster service deployment, a complete cluster service that can provide services to the outside world includes the cluster service itself and various middleware instances that need to be used. The current main solution is to incubate independent middleware instances for cluster services and perform subsequent middleware instance configuration. This method not only increases the complexity of cluster service deployment, but also requires the deployment of cluster services to focus not only on themselves but also on the deployment of dependent middleware instances, which greatly wastes cluster resources.

[0003] The middleware instance itself supports various levels of isolation and has various solutions for multiple users; cluster services are more concerned with using the capabilities provided by the middleware instance and do not require that the middleware instance be exclusive. Therefore, if multiple cluster services share a middleware instance, it can not only greatly save cluster resources and thus deploy more cluster services, but also improve the efficiency of cluster service deployment.

[0004] In practical applications, how to screen out middleware instances that meet the sharing requirements of cluster services, use them as dependent resources of cluster services, and accurately and efficiently uninstall successfully deployed cluster services according to business needs in the architecture of middleware instance sharing has become a technical problem that needs to be solved urgently. Summary of the invention

[0005] In view of this, in order to overcome the deficiencies of the prior art, the present invention provides a method for deploying cluster services based on an incubated middleware instance.

[0006] In one aspect, the present invention provides a method for deploying a cluster service based on an incubated middleware instance, comprising:

[0007] Step S1: Build the basic information of the cluster service and upload the installation resource files required by the cluster service to the product center;

[0008] Step S2: Filter the middleware instances that can be shared and are in running state in the k8s cluster;

[0009] Step S3: matching the middleware instance screened in step S2 according to the basic information of the middleware instance, and configuring the matched middleware instance;

[0010] Step S4: installing the installation resource file into the corresponding namespace according to the configured middleware instance, and executing the deployment of the cluster service.

[0011] Furthermore, in step S1 of the method for deploying a cluster service based on an incubated middleware instance of the present invention, the basic information of the cluster service includes a name and an authority level.

[0012] Furthermore, step S2 of the method for deploying cluster services based on incubated middleware instances of the present invention includes: screening middleware instances with shared tags and a running status of running in the k8s cluster.

[0013] Furthermore, in step S3 of the method for deploying cluster services based on incubated middleware instances of the present invention, the basic information of the middleware instance includes the type of the middleware, the specification description of the middleware instance, and the configuration parameters of the middleware instance.

[0014] Furthermore, step S3 of the method for deploying cluster services based on the incubated middleware instance of the present invention includes:

[0015] Step S31: matching a corresponding middleware instance among the middleware instances screened in step S2 according to the type of the middleware and the specification description of the middleware instance;

[0016] Step S32: Use the configuration parameters of the middleware instance to configure the matched middleware instance.

[0017] Furthermore, step S4 of the method for deploying cluster services based on the incubated middleware instance of the present invention includes:

[0018] Step S41: Rendering the corresponding resource file according to the permission level of the cluster service, and injecting the rendered resource file into the installation resource file;

[0019] Step S42: Create a namespace according to the name in the basic information of the cluster service;

[0020] Step S43: using the connection information of the middleware instance configured in step S32 as a parameter of the installation resource file, and installing the installation resource file into the corresponding namespace using the parameter;

[0021] Step S44: cyclically checking the deployment status of the cluster service. When the deployment of the cluster service reaches the deployment time threshold but is not completed, the deployment status of the cluster service is updated to deployment failure. When the deployment of the cluster service is completed, the deployment status of the cluster service is updated to deployment success.

[0022] Furthermore, the method for deploying cluster services based on incubated middleware instances of the present invention further includes: uninstalling the cluster services deployed in step S4 according to business requirements.

[0023] Furthermore, in the method for deploying cluster services based on the incubated middleware instance of the present invention, the cluster services deployed in step S4 are uninstalled according to business requirements, including:

[0024] Determine whether the middleware instance corresponding to the cluster service to be uninstalled is isolated, and delete the middleware instance according to the determination result;

[0025] Delete all resources in the corresponding namespace in the k8s cluster according to the name of the cluster service, and delete the corresponding namespace.

[0026] Furthermore, in the method for deploying cluster services based on incubated middleware instances of the present invention, it is determined whether the middleware instance corresponding to the cluster service to be uninstalled is isolated, and the middleware instance is deleted according to the determination result, including:

[0027] If the middleware instance is used by other cluster services at the same time, remove the configuration corresponding to the cluster service to be uninstalled in the middleware instance;

[0028] If the middleware instance is not used by other cluster services, all resources corresponding to the middleware instance in the k8s cluster are deleted.

[0029] On the other hand, the present invention also provides a computer device, comprising a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the steps of the method are implemented when the processor executes the program.

[0030] The method for deploying cluster services based on incubated middleware instances of the present invention has the following beneficial effects:

[0031] 1. By screening the sharable and running middleware instances in the k8s cluster, the cluster service does not need to re-incubate the middleware instances, which optimizes the utilization efficiency of the middleware instances in the cluster and improves the cluster service deployment efficiency.

[0032] 2. By judging whether the middleware instance corresponding to the cluster service that needs to be uninstalled is isolated, the middleware instance is deleted according to the judgment result, and the cluster service in the k8s cluster is deleted according to the name of the cluster service. In this way, the successfully deployed cluster services can be automatically uninstalled accurately and efficiently according to business needs in the architecture of middleware instance sharing.
