In the embodiment of the invention, when the detection task creation event is not triggered, the detection result of the created detection task is obtained, and the task description file corresponding to the created detection task is updated according to the detection result of the created detection task. Namely, when no event triggering to create the detection task exists, the detection result of the created detection task can be obtained at regular time so as to update the task description file; the detection result in the task description file can be continuously scanned to judge whether the state of the component to be detected is abnormal or not, or if the number of times of detecting the state abnormality exceeds a preset threshold value, the alarm service is invoked.

The flowcharts and block diagrams in the figures illustrate the architecture, functionality, and operation of possible implementations of systems, methods and computer program products according to various embodiments of the present invention. In this regard, each block in the flowchart or block diagrams may represent a module, segment, or portion of code, which comprises one or more executable instructions for implementing the specified logical function(s). It should also be noted that, in some alternative implementations, the functions noted in the block may occur out of the order noted in the figures. For example, two blocks shown in succession may, in fact, be executed substantially concurrently, or the blocks may sometimes be executed in the reverse order, depending upon the functionality involved. It will also be noted that each block of the block diagrams or flowchart illustration, and combinations of blocks in the block diagrams or flowchart illustration, can be implemented by special purpose hardware-based systems which perform the specified functions or acts, or combinations of special purpose hardware and computer instructions.
The modules involved in the embodiments of the present invention may be implemented in software or in hardware. The described modules may also be provided in a processor, for example, as: a processor includes a determination module and an execution module. The names of these modules do not constitute a limitation on the module itself in some cases, and for example, the judgment module may also be described as "a module that judges whether to trigger detection of a task creation event in response to listening to creation or update of a task description file".
As another aspect, the present invention also provides a computer-readable medium that may be contained in the apparatus described in the above embodiments; or may be present alone without being fitted into the device. The computer readable medium carries one or more programs which, when executed by a device, cause the device to include: responding to the monitoring of the creation or updating of the task description file, and judging whether to trigger the detection of a task creation event; if yes, acquiring a plurality of task description contents of a task list in a task description file, wherein each task description content indicates a component to be tested; creating a detection task according to task description content so as to detect a component to be detected corresponding to the task description content; acquiring a detection result of the component to be detected corresponding to the task description content, and updating the task description file according to the detection result; otherwise, no detection task is created.
According to the technical scheme of the embodiment of the invention, the method for detecting the state of the cluster component judges whether to perform the creation of the detection task or not through the creation or update monitoring of the task description file so as to acquire the detection result of the detection task on the state of the component to be detected. The method is a detection type K8s cluster component availability detection method which can be customized by a user, and the user can write a task description file in a simple customized mirror image mode, so that the detection capability is integrated into the detection process, additional integration is not needed, and the integration cost is low; the method does not depend on third party storage, and has low maintenance cost; the method can actively sense the abnormality of the component and achieve the purpose of alarming, and can acquire the running state of the component before use and timely process faults.
The above embodiments do not limit the scope of the present invention. It will be apparent to those skilled in the art that various modifications, combinations, sub-combinations and alternatives can occur depending upon design requirements and other factors. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of the present invention.
