In the embodiment of the invention, attributes of the detection tasks (probe) are described in the task description file (probe-descriptor), such as time intervals of execution of the detection tasks, images of execution of the detection tasks, parameters of execution of the detection tasks and the like, and the task description file can be converted into kubernets (K8s, open source container orchestration engine) resources by parsing the task description file to create the detection tasks in the K8s cluster. The task description file can be a yaml (markup language) format file, and readability is good.
The user can custom write the task description file and create the resource in the K8s cluster. The task description file comprises a task list (probeList), the task list comprises a plurality of task description contents, each task description content is used for describing each detection task, namely the task list describes a set of detection tasks, each task description content indicates a component to be detected, each task description content can obtain a corresponding K8s resource by analyzing each task description content, and the detection tasks are created in a K8s cluster. The component to be tested may be a component based on a K8s cluster, such as a DNS server (domain name server), a POD (minimal resource management component in kubernets), and the like.

The task description file includes an execution mode field (policy) for describing whether the execution mode of the detection task is single execution or loop execution. The task description file also comprises an identity field, and when the value of the identity field is changed, the task description file is updated.
Monitoring creation or update of a task description file in a list-watch (asynchronous message passing mode in K8 s) mode to judge whether a detection task creation event is triggered, optionally, judging whether a detection task creation event is triggered by judging whether a value of an identity field (md5) of the task description file is changed, and if the value of the identity field is changed, triggering the detection task creation event; if the value of the identity field has not changed, then no detection task creation event is triggered.
Optionally, whether to trigger the detection task creation event may also be determined by whether the task list is changed, and if the task description content in the task list is changed, the detection task creation event is triggered; and if the task description content in the task list is not changed, not triggering the detection task creating event.

Therefore, each task description content in the task list is converted into a detection task in a different execution mode, namely each task description content is converted into a detection task (joba) which is executed once, or each task description content is converted into a detection task (cornjoba) which is executed circularly. And the detection task executed once, such as a detection task for detecting whether DNS server analysis is normal or not, and the detection task executed circularly, such as whether POD can be normally created or not.

Wherein the custom image complies with the following specification: the task description content is in a detection mode, for example, whether DNS analysis is normal or not is detected, and whether a Pod can be normally created or not is detected; if the execution mode of the detection task is the timing cycle execution, the detection task is realized through an execution mode field; and ensuring that the detection result can be updated into the identity field of the task description file, and reading the parameters in the task description content from the environment variables.
In the embodiment of the invention, when the detection task creating 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. When the event for creating the detection task is not triggered, the detection result of the created detection task can be obtained at regular time so as to update the task description file; and 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 the number of times of detecting the abnormal state exceeds a preset threshold value, and then the alarm service is called.
