Description

Chaos testing method and device, electronic equipment and storage medium

Technical Field

The present invention relates to the field of computer technologies, and in particular, to a chaotic test method and apparatus, an electronic device, and a storage medium.

Background

When a distributed system is gradually complicated, and the system is gradually clouded, the stability of the system is greatly challenged. The chaotic test can actively find out weak links in the system and check the coping method of the system under the sudden condition, thereby enabling the system to be more robust.

At present, the chaos test is widely applied, and a good chaos test tool becomes the key of the test. In the existing chaos testing tool, fault injection can be performed for a node (node), a pod (pod) and a container (container), and as a fault at the node (node) level affects not only a target system to be tested, all systems deployed on the whole node (node) can be affected. Therefore, an authority verification module is needed to ensure that the test is normally carried out and other systems are not influenced.

Current rights management schemes are non-zero, i.e., one, in that a user can only use and cannot use two rights. Any node, pod and container based fault injection can be created as long as the user has access rights, and no right control is subdivided down. This open management approach may cause unnecessary impact on other systems deployed on the same node, thereby affecting the security of the system during the testing process.

Example one

Fig. 1 is a flowchart of a chaos testing method according to an embodiment of the present invention, where the embodiment is applicable to a chaos testing situation for a cluster service platform, and the method can be executed by a chaos testing apparatus, where the chaos testing apparatus can be implemented in hardware and/or software, and the chaos testing apparatus can be configured in a cloud server. As shown in fig. 1, the method includes:

s110, under the condition that the testing user passes the testing authority verification, platform service resources are obtained based on testing information of the testing user.

In the current chaos test, the user authority set by the test user is limited to a non-one, namely zero authority management mode, that is, if the user can access the current system, the user can perform the chaos test at any test position of the current system, but in the test mode, if the user performs the chaos test at a node position in the current system, other applications running at the test node are caused to run to generate faults, so that the continuity and the safety of the system running are influenced. In order to solve the above problem, in the technical scheme of the embodiment of the present invention, before the test user performs the chaos test, the test authority is verified based on the test position of the test user to be performed, that is, it is determined whether the test position of the test user performing the chaos test exceeds a preset range. When the test user passes the test verification, the test position of the test user to be tested does not exceed the preset range, and the test user is allowed to carry out the chaotic test at the test position of the test user to be tested.

Specifically, the authority verification may be performed on the test user based on a preset test management service of the cluster service platform, and after the test user passes the verification, the chaotic test may be performed on the cluster service platform based on the preset test management service. Optionally, the cluster service platform may be kubernets, and correspondingly, the preset test management service may be an operator component in kubernets. Specifically, the operator component is obtained by writing in Go language.

Optionally, the method for performing permission verification on a test user based on a preset test management service in the embodiment of the present invention may include: when a test instruction of a test user is received, obtaining test information of the test user; and acquiring a preset authority verification mechanism, and performing test authority verification on the test information based on the authority verification mechanism to determine whether the test user passes the test authority verification.

In this embodiment, the test user may be a user performing a chaotic test on the system, and the test information may also be understood as test information for performing the chaotic test on the system, and optionally, the test information may be obtained based on test document generated in advance. Specifically, the test information may include information such as a test position where the test user performs the test.

Specifically, the test user processes the obtained test information through yaml to create a user resource for generating the custom resource. It should be noted that the user resource may be an initial platform service resource that needs to be adjusted. Namely, after resource adjustment is carried out on user resources, platform service resources for carrying out the chaos test can be obtained. Furthermore, an authority verification mechanism in the preset test management service is obtained based on the user resources, and test authority verification is carried out on the test information based on the authority verification mechanism.

In an embodiment, the test information includes a test location and a test namespace scope. Correspondingly, the method for verifying the test authority of the test information comprises the following steps: sequentially carrying out authority verification on the testing position and the testing name space scope based on an authority verification mechanism; and if the testing position and the testing name space scope pass the verification, the testing user passes the testing authority verification.

It should be noted that the test locations include a level of the test locations injected with the test faults in the cluster service platform. The cluster service platform of this embodiment includes nodes (nodes), pods (pod), and containers (container) that are ordered in order from high to low.

Specifically, a test position where a fault needs to be injected in test information is obtained, and the authority verification mechanism performs first-level test authority verification on the test position based on a test position threshold preset in the authority verification mechanism. Optionally, if the test location is within the test location threshold range, it indicates that the current test user passes the authorization verification for the test location. For example, whether the test position is within the test position threshold may be understood as: when the test position threshold is a pod (pod), when the test position of the test user is a container (container) or a pod (pod), the test user passes the authority verification of the test position; otherwise, when the test position of the test user is a node (node), the test user fails the authority verification for the test position.

It should be noted that, if the test location fails to be verified, the first test prompt information is generated based on a preset test location threshold, so that the test user generates a test location meeting the test location threshold.

Specifically, when the test user receives the first test prompt message, the test user may modify the test position of the test user based on the test position threshold in the first test prompt message to generate a test position within the test position threshold range, so that the test position can be verified; of course, the test user may also regenerate the test position within the test position threshold range, and perform subsequent chaotic tests based on the test position.

Optionally, when the test user passes the permission verification for the test location, the test namespace scope is tested for the test user to perform the second-level test permission verification.

Specifically, whether a test namespace scope corresponding to the test position exists or not is searched in the cluster service platform. Optionally, if the test namespace exists, the test user passes the authority verification of the test namespace scope; otherwise, if the test namespace scope does not exist, the test namespace scope is judged to be verified.

It should be noted that, if the test namespace scope is not verified, the second test prompt message is generated based on the preset test namespace scope threshold, so that the test user generates the test namespace scope meeting the test namespace scope threshold.

The preset test namespace scope threshold value can be understood as the namespace scope existing in the cluster service platform. Specifically, when the test user receives the second test prompt message, the test namespace scope of the test user can be modified based on the test namespace scope threshold in the second test prompt message to generate the test namespace scope within the test namespace scope threshold range, so that the test namespace scope can be verified through the test namespace scope. Of course, the test user can also regenerate the test namespace scope within the threshold range of the test namespace scope and perform subsequent chaotic tests based on the test namespace scope.

Optionally, when both the test location and the test namespace scope pass the verification, it is indicated that the test user passes the test permission verification; otherwise, if any one of the test position or the test namespace scope fails to pass the verification, it indicates that the test user passes the test permission verification, that is, the test user does not have the permission to perform the chaotic test.

Optionally, when the test user passes the test permission verification, that is, when the test user has the test permission, finiizers is set for the previously created user resource to obtain the created platform service resource, that is, the paas blade is obtained.

S120, when the resource state change of the platform service resources is detected, determining chaotic test resources based on the platform service resources.

In the embodiment of the present invention, the chaotic test resource may be a resource for injecting a test fault when performing a chaotic test. Specifically, chaos testing resources in kubernets can be understood as chaos blade.

In practical application, after the platform service resource is created, the preset test management service of the cluster service platform monitors the platform service resource to acquire the change condition of the resource state of the platform service resource. In this embodiment, the resource creation of the platform service resource also belongs to one of the resource state changes, and specifically, the other state change types further include resource modification of the platform service resource and resource deletion of the platform resource service resource.

Optionally, the method for monitoring platform service resources in this embodiment may include: acquiring a preset monitoring mechanism, and monitoring platform service resources in the cluster service platform based on the monitoring mechanism; and determining whether the resource state of the platform service resource changes or not based on the monitoring result.

The preset monitoring mechanism may be understood as a loop processing (receiving) mechanism of the operator. In practical applications, when the PaaSBlade is created, the controller in the operator monitors the creation operation and then enters a loop processing (receiver) mechanism. When the cyclic processing monitors that the platform service resource is subjected to the operation of adding and deleting, the resource state of the platform service resource is changed.

On the basis of the above embodiment, when the resource state changes, the chaotic test resource is determined based on the changed platform service resource. Optionally, the method for creating the chaotic test resource based on the platform service resource in this embodiment may include: and acquiring event operation corresponding to the resource state change, and performing corresponding operation on the platform service resource based on the event operation to obtain the chaotic test resource.

The event operation may include a delete operation, an acquire operation, and the like. Specifically, after the event operation corresponding to the state change is determined, the event result corresponding to the operation result after the event operation is judged, the obtaining mode of obtaining the chaotic test resource is determined based on the event result, and the chaotic test resource is obtained based on the obtaining mode.

For example, the event operation corresponding to the change of the resource state is determined as the acquisition operation. Further, whether the obtaining operation is successfully obtained or not is determined, and if the obtaining operation is successfully obtained, chaotic test resources are directly obtained based on the obtaining result; otherwise, if the acquisition is unsuccessful, the chaotic test resource is established based on the platform service resource.

S130, generating a test case of the cluster service platform based on the chaotic test resource and the test information, and testing the cluster service platform based on the test case.

In this embodiment of the present invention, a method for testing a cluster service platform may include: determining a plurality of test positions of the cluster service platform based on the test information, and respectively injecting test faults into the test positions based on the chaotic test resources; and generating a test case of the cluster service platform based on each test fault, and testing the cluster service platform based on the test case.

Specifically, the test position included in the test information is acquired, and the corresponding test position is determined based on the test position. Illustratively, if the test level comprises pods (pod) and containers (container), determining test pods (pod) needing to be tested based on the test information, determining the test containers (container) needing to be tested in the test pods (pod), using the determined test pods (pod) and test containers (container) as test positions for injecting test faults, injecting the test faults in each position, generating test cases of the cluster service platform based on the injected test faults and other test information, and testing the test cases to complete the chaotic test of the cluster service platform.

According to the technical scheme provided by the embodiment of the invention, under the condition that the test user passes the test permission verification, platform service resources are obtained based on the test information of the test user; determining chaotic test resources based on the platform service resources when the resource state change of the platform service resources is detected; and generating a test case of the cluster service platform based on the chaotic test resource and the test information, and testing the cluster service platform based on the test case. According to the technical scheme, before the chaotic test is carried out based on the test user, the test authority is verified based on the test position to be carried out of the test user, namely, whether the test position of the test user for the chaotic test exceeds a preset range or not is determined. When the test user passes the test verification, the test user is allowed to carry out the chaos test, the problem that the fault injection of one project influences the conditions of other projects deployed on the same node in the test process of the prior art is solved, the purpose of protecting the system from being influenced in the chaos test is achieved, and the safety of the system operation is improved.

On the basis of the above embodiment, the embodiment of the present invention also provides a preferred embodiment. The preferred embodiment describes the chaos testing method in detail by taking kubernets as an example of the cluster service platform in the embodiment of the present invention. Optionally, the chaos testing method in the preferred embodiment of the present invention includes the following steps: the method comprises the steps of firstly not granting the user the authority of using the ChaosBlade tool, and then opening the authority of authorizing the user to use the PaaS blade tool. When a user creates and uses a PaaS blade tool object through a yacl file, authority check is carried out on a fault injection test to be created by the user, and after the authority check is passed, a PaaS blade tool creates and uses a ChaoS blade tool object to carry out fault injection; and when the check fails, directly refuting the user request back, informing the reason of the failure, and asking the user to retry after modifying the yaml file.

Optionally, a method for checking the authority of the user may be as shown in fig. 2. Specifically, the user needs to create CRD of the custom resource by yaml. After the resources are created, the PaaS blade utilizes a webhook mechanism of an operator to carry out validity verification on the resources, and finally finalizers are set. Specifically, the valid verification step includes: determining a fault injection position based on resources created by a user, and verifying whether the fault injection position meets a verification condition; if not, feeding back error information to the user; and if so, carrying out name space scope verification. Verifying whether the namespace scope verification meets the verification condition; if the user identification information is in accordance with the user identification information, the user identification information passes verification, and if the user identification information is not in accordance with the user identification information, error information is fed back to the user.

Optionally, a method for obtaining chaos blade based on paas blade may be shown in fig. 3. Specifically, the processing flow of paas blade is a loop operation (reconcile), and when the monitored resource is subjected to an add/delete operation, the controller obtains information of the monitored resource, so as to perform further processing. The method comprises the following specific steps: 1. when a trigger condition occurs, acquiring a user-defined resource object of the PaaS blade operator according to a name (namespace) and a resource name (name); 2. checking whether the acquisition is successful; 3. if the unsuccessful certification is the deletion operation, jumping to the step 1; 4. if the acquisition is successful, checking whether the operation is a deleting operation; 5. if the operation is deletion, firstly deleting other resources created by the resources, such as the customized resources of a ChaosBlade tool, then updating the state of the PaaSBlade customized resource object, and jumping to the step 1; 6. if the operation is not the deleting operation, acquiring a customized resource object of the ChaosBlade according to the name (namespace) and the name (name) of the resource; 7. if the acquisition is successful, jumping to the step 9; 8. if the acquisition is unsuccessful, a custom resource of a ChaosBlade tool is created; 9. updating the state of the PaaS blade custom resource object; and 10, returning to the starting point of the loop (reconcile) and waiting for the next trigger.

More specific examples of a machine-readable storage medium would include an electrical connection based on one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing.

To provide for interaction with a user, the systems and techniques described here can be implemented on an electronic device having: a display device (e.g., a CRT (cathode ray tube) or LCD (liquid crystal display) monitor) for displaying information to a user; and a keyboard and a pointing device (e.g., a mouse or a trackball) by which a user can provide input to the electronic device. Other kinds of devices may also be used to provide for interaction with a user; for example, feedback provided to the user can be any form of sensory feedback (e.g., visual feedback, auditory feedback, or tactile feedback); and input from the user can be received in any form, including acoustic, speech, or tactile input.

The systems and techniques described here can be implemented in a computing system that includes a back-end component (e.g., as a data server), or that includes a middleware component (e.g., an application server), or that includes a front-end component (e.g., a user computer having a graphical user interface or a web browser through which a user can interact with an implementation of the systems and techniques described here), or any combination of such back-end, middleware, or front-end components. The components of the system can be interconnected by any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include: local Area Networks (LANs), wide Area Networks (WANs), blockchain networks, and the Internet.

The computing system may include clients and servers. A client and server are generally remote from each other and typically interact through a communication network. The relationship of client and server arises by virtue of computer programs running on the respective computers and having a client-server relationship to each other. The server can be a cloud server, also called a cloud computing server or a cloud host, and is a host product in a cloud computing service system, so that the defects of high management difficulty and weak service expansibility in the traditional physical host and VPS service are overcome.
