Description

Technical Field

[0001] The present invention relates to the technical field of chaos engineering, and particularly to a method, device, equipment and storage medium for determining virtual component installation steps. Background Art

[0002] Since the experiments of the chaos platform are widely used as long as the operating system is accessible, the host as the operation object can be used regardless of whether its architecture and software are complete. For the existing platform, manual deployment supports users to install virtual components according to the actual situation. Once the number of users, the number of hosts and the number of reinstallations increase, more additional workload is added to the use of chaos in addition to the main experimental function, which greatly affects the installation efficiency of virtual components (probes).

[0003] Obviously, how to improve the installation efficiency of virtual components is a technical problem that those skilled in the art urgently need to solve. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a method, device, equipment and storage medium for determining virtual component installation steps, which solves the technical problem of low installation efficiency of virtual components in the prior art.

[0005] To solve the above technical problem, the present invention provides a method for determining virtual component installation steps, which is applied to a chaos engineering platform and includes:

[0022] When the installation step needs to be executed only in the target installation scenario, determine that the branch control information of the current installation step is a must for the specific installation scenario.

[0023] On the other hand, after determining the time-optimal virtual component installation steps corresponding to each installation scenario based on the execution speed, the dependency relationship, and the branch control information, and implementing the simultaneous installation of the parallel installation steps in the time-optimal virtual component installation steps using the multi-thread method, it further includes:

If the value of whether the virtual components have been installed is true, and the value of whether the virtual components to be installed are connected is true, and the value of whether the virtual components have been started is false, then start the virtual components and set the value of whether the virtual components have been started to "starting";

[0047] Continue to traverse the next host for virtual component startup until the traversal is completed;

[0048] Traverse the installation table based on a set time interval to determine whether the virtual components have been installed;

[0049] If the value of whether the virtual components have been installed is true, and the value of whether the virtual components to be installed are connected is true, and the value of whether the virtual components have been started is "starting", then determine whether the virtual components have been started based on the second port information;

Since the time-optimal virtual component installation steps include parallel steps determined based on the execution speed and dependency relationship, and steps are deleted based on the branch control information, the current installation steps are the time-optimal installation steps, thereby improving the installation efficiency of virtual components.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the listed steps or units, but may include steps or units not listed.

[0074] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners.

[0075] ChaosBlade is a chaos engineering project that was open-sourced in 2019. It includes the chaos engineering experiment tool chaosblade and the chaos engineering platform chaosblade-box, aiming to help enterprises solve high-availability problems in the cloud-native process through chaos engineering. The experiment tool chaosblade supports 3 major system platforms and 4 programming language applications, covering more than 200 experiment scenarios and more than 3,000 experiment parameters, enabling fine-grained control of the experiment scope. The chaos engineering platform chaosblade-box supports the hosting of experiment tools. In addition to hosting chaosblade, it also supports the Litmuschaos experiment tool. The main elements of the experiment are scenarios and operation objects. The connection between scenarios and operation objects is achieved through probes. The current platform supports manual deployment of probes and automatic installation of individual probes. Since the experiments on the chaos platform are widely used and only require access to the operating system, the operation object, i.e., the host, can be used regardless of its architecture and software completeness. However, the existing manual deployment of the platform allows users to install probes according to the actual situation. Once the number of users, hosts, and reinstallation times increases, more additional workload is added to the use of chaos beyond the main experiment function, deviating from the original intention of chaos to release human resources. Therefore, it is particularly important to find a way to optimize the probe installation steps.

[0076] Next, a method for determining the installation steps of virtual components provided in the embodiments of the present invention will be described in detail. Figure 1 The flowchart of a method for determining the installation steps of virtual components provided in the embodiments of the present invention is applied to a chaos engineering platform. The method may include:

[0077] S101, obtain multiple installation steps corresponding to the virtual component to be installed.

[0078] The execution subject in this embodiment is the chaos engineering platform. The virtual component to be installed in this embodiment is a probe. This embodiment does not limit the specific installation steps. The installation steps in this embodiment may be all the steps for installing the virtual component; or the installation steps in this embodiment may be multiple main installation steps.

[0079] It should be further noted that the multiple installation steps corresponding to the virtual component to be installed described above may include: obtaining multiple main installation steps corresponding to the virtual component to be installed; where the main installation steps include confirming whether the host of the virtual component to be installed already exists in the database, determining whether the host virtual component service of the virtual component to be installed has been started, determining the connectivity of the host address of the virtual component to be installed, determining whether the virtual component has been installed on the host of the virtual component to be installed, determining the host architecture of the virtual component to be installed, installing the virtual component, starting the virtual component, and updating the installation database record. When the installation steps in this embodiment are multiple main installation steps, it is not necessary to obtain all the installation steps, so only the time-optimal virtual component installation steps corresponding to the multiple main installation steps need to be determined, thereby improving the efficiency of the time-optimal virtual component installation steps.

[0080] S102. Determine the execution speed, dependency relationship, and branch control information corresponding to each installation step; where the branch control information is the information for determining whether the current installation step is a must-execute step.

[0081] The execution speed in this embodiment is used to determine the steps with a slow installation speed, and based on the dependency relationship, it is determined whether parallel installation can be performed on the steps with a slow installation speed. The branch control information in this embodiment is to determine whether this step is a must-execute step. If not, this step can be skipped.

[0082] It should be further noted that based on any of the above embodiments, in order to improve the accuracy of determining the execution speed, dependency relationship, and branch control information, determining the execution speed, dependency relationship, and branch control information corresponding to each installation step may include:

[0083] S1021. Obtain the execution time corresponding to each installation step.

[0084] S1022. When the execution time corresponding to the installation step is lower than the set minimum execution time threshold, determine that the execution speed in the step characteristics is fast execution.

[0085] This embodiment does not limit the specific minimum execution time threshold. For example, the minimum execution time threshold in this embodiment can be 1 second; or the minimum execution time threshold in this embodiment can be 2 seconds.

[0086] S1023. When the execution time corresponding to the installation step is lower than the minimum execution time threshold, determine that the execution speed parameter in the step characteristics is slow execution.

[0087] S1024. Determine whether each installation step depends on other installation steps.

[0088] S1025, when depending on other installation steps, determine that the dependency of the current installation step is the target installation step to be depended on; wherein, the type of the target installation step to be depended on includes indirect dependency.

[0089] The indirect dependency in this embodiment does not directly depend on a certain step, but comes after this step. For example, B depends on A, and C depends on B. At this time, C indirectly depends on A.

[0090] S1026, when not depending on other installation steps, determine that the dependency of the current installation step is empty.

[0091] S1027, determine whether the current installation step is a step to be executed in any installation scenario.

[0092] S1028, when the installation step is to be executed in any installation scenario, determine that the branch control information of the current installation step is a mandatory item.

[0093] S1029, when the installation step does not need to be executed in any installation scenario, determine that the branch control information of the current installation step is a non-mandatory item.

[0094] S10210, when the installation step needs to be executed only in the target installation scenario, determine that the branch control information of the current installation step is a mandatory item for the specific installation scenario.

[0095] For ease of understanding, when multiple steps are the main installation steps as described above, the execution speed, dependency, and branch control information corresponding to each main installation step are shown in Table 1.

[0096] Table 1 A schematic table of an execution speed, dependency, and branch control information

[0097]

[0098] To make the dependency clearer, please refer to Figure 2 , Figure 2 which is a schematic diagram of the dependency of the main installation steps provided by the embodiment of the present invention. As can be seen from Figure 2 it, b directly depends on a; c depends on b and indirectly depends on a.

[0099] S103, determine multiple installation scenarios based on the condition information corresponding to the installation step; wherein, the condition information is the information determined based on whether the conditions in the installation step are met.

[0100] This embodiment determines multiple installation scenarios based on the conditional information corresponding to the installation steps, which means that there are judgment conditions in some installation steps. If so, one path will be executed; if not, another path will be executed, thus forming two scenarios. This embodiment does not limit the specific method for determining multiple installation scenarios. For example, this embodiment can determine multiple installation scenarios through permutation and combination of conditional information; or this embodiment can also determine multiple installation scenarios through a decision tree.

[0101] It should be further noted that, based on any of the above embodiments, determining multiple installation scenarios based on the conditional information corresponding to the installation steps may include: obtaining the installation steps with conditional information, analyzing the installation steps with conditional information to obtain the corresponding decision tree structure, and analyzing based on the decision tree structure to determine multiple installation scenarios. This embodiment can identify the conditional information included in the installation steps and construct a decision tree according to the conditional information. Each node of the decision tree represents a conditional judgment, and each branch represents the result of the condition (usually "yes" or "no"). Starting from the root node, according to the logical order and dependency of the conditions, gradually construct the branches of the tree. Ensure that the decision tree covers all possible conditional combinations, and define one or more installation scenarios at the end of each branch. By traversing the decision tree and analyzing each branch path, determine the installation scenario corresponding to each path. This embodiment determines multiple installation scenarios through a decision tree, which can improve the accuracy and efficiency of determining installation scenarios.

[0102] S104, determine the time-optimal virtual component installation steps corresponding to each installation scenario based on the execution speed, dependency relationship, and branch control information, and use the multi-thread method to implement the simultaneous installation of the parallel installation steps in the time-optimal virtual component installation steps; where the time-optimal virtual component installation steps include parallel installation steps determined based on the execution speed and dependency relationship, and steps that do not need to be executed determined based on the branch control information.

[0103] This embodiment determines the time-optimal virtual component installation steps corresponding to each installation scenario based on the execution speed, dependency relationship, and branch control information, so that when installing in different installation scenarios, the time for the virtual component installation steps is the shortest, improving the virtual component installation efficiency. This embodiment uses the multi-thread method to implement the simultaneous installation of the parallel installation steps in the time-optimal virtual component installation steps. It can be understood that the chaos engineering platform realizes parallelism by calling the thread method. For example, thread1: detection, thread2: installation; thread3 starts.

[0104] It should be further noted that, based on any of the above embodiments, after determining the time-optimal virtual component installation steps corresponding to each installation scenario based on the execution speed, dependency relationship, and branch control information, and implementing the simultaneous installation of the parallel installation steps in the time-optimal virtual component installation steps using a multi-threaded method, it may further include: installing the virtual component to be installed based on the time-optimal virtual component installation steps corresponding to the current installation scenario; during the installation of the virtual component to be installed, persisting the process of each installation step based on the installation storage service; where the installation storage service is a tool for storing virtual component installation information. This embodiment does not limit the specific installation storage service. For example, the installation storage service in this embodiment may be a database; or the installation storage service in this embodiment may also be a hard disk. By persisting each actual installation step, this embodiment enables quick determination of which installation steps have been completed, thereby improving the efficiency of subsequent judgment on whether the installation process is complete.

[0105] It should be further noted that, based on any of the above embodiments, during the installation of the virtual component to be installed, persisting the process of each installation step based on the installation storage service may include:

[0106] S1, traversing the host list of the virtual component to be installed;

[0107] The execution of this embodiment is a chaos engineering platform, and the environment where the chaos engineering platform executes is any machine with an operating system.

[0108] S2, determining whether the host address of the current host is in the installation table in the installation storage service;

[0109] S3, if the current host address is not in the installation table, adding a new initial information record corresponding to the host to the installation table; where the information in the installation table includes the host address of the virtual component to be installed, the installation package required to install the virtual component, whether the virtual component has been installed, whether the virtual component to be installed has been connected, whether the virtual component has been started, and the installation result;

[0110] S4, if the current host address is in the installation table, determining whether the host address is reachable based on a network fault diagnosis tool;

[0111] In this embodiment, the chaos engineering platform determines whether the host address is reachable by sending a ping command. Ping is a network fault diagnosis tool used to detect the connectivity between network hosts.

[0112] S5, if it is reachable, determining that the value of whether the virtual component to be installed has been connected is true based on the protocol for remotely accessing and managing computers over a network;

[0113] In this embodiment, the chaos platform determines whether the value of whether the virtual component to be installed is connected is true by sending a Telnet command, that is, whether the host port is connectable. The Telnet protocol is a protocol for remotely accessing and managing computers over a network. It allows users to connect to a remote host over a network and operate on the system resources of the remote host on a local terminal, just as if operating directly in front of the console of the remote host. In the scenario of the chaos platform, the platform utilizes this feature of the Telnet protocol to send a Telnet command to a specific port of the target host. If the connection can be successfully established, it indicates that the corresponding port of the host is open and connectable; if the connection fails, it indicates that the port may be closed, blocked by a firewall, or there are other network problems preventing connectivity. In this way, the chaos platform can quickly detect the connectivity of the host port, providing a basis for subsequent operations such as testing, monitoring, or troubleshooting.

[0114] S6, if it is not connectable, then determine that the value of whether the virtual component to be installed is connected is false, and the installation result is that the host cannot be connected. Please confirm the connection and then install the virtual component.

[0115] S7, determine whether the virtual component is installed based on the time-optimal virtual component installation steps.

[0116] S8, if the virtual component has been installed, then determine that the value of whether the virtual component has been started is set to true, and the installation result is that the host plugin has been started and no installation is required.

[0117] S9, if the virtual component has not been installed, then determine that the value of whether the virtual component has been started is set to false.

[0118] S10, obtain the host architecture of the virtual component to be installed and update the value of the installation package required for installing the virtual component in this record to be not empty.

[0119] S11, continue to traverse the next host until the traversal is completed, and complete the update of the installation table.

[0120] S12, re-traverse the installation table based on the traversal period.

[0121] This embodiment does not limit the specific traversal period. For example, the traversal period in this embodiment is 300 seconds; or the traversal period in this embodiment is 200 seconds. The virtual component in this embodiment is a probe. At this time, the overall process may include: obtaining the host list hosts corresponding to the probe to be installed, whose value is [host1, host2, host3... hostn], traversing the host list hosts of the probe to be installed, and determining whether the hostIp (host address) of hostx is in the table install_table in the database. If it exists, continue to the next step; if not, add a record of hostx to install_table, and the record format is [hostIp, installPackage, installed, linked, started, message], and its initial value can be [hostIp, empty, false, true, false, empty]. Field explanation: hostIp: the host IP of the probe to be installed; installPackage: the installation package required to install the probe; installed: whether the probe has been installed, default is false, that is, not installed by default; linked: whether the probe to be installed has been connected, default is true, that is, can be connected; started: whether the probe has been started, default is false, that is, not started; message: installation result, default is empty. This embodiment can determine whether hostx's hostIp is reachable through ping, execute the command: ping–c 5 hostip. If the return result is 5 received, it means it is reachable and no operation is required; otherwise, set linked to false, and message is: The host hostx cannot be connected. Please confirm the connection and then install the probe. Determine whether the probe is installed by checking the port availability, execute the command: telnet hostip 19527. If the return result is Connected, it means the probe has been installed, then set started to true, and message is: The hostx plugin of the host has been started and no installation is required; otherwise, no operation is required. Obtain the architecture of the host hostx of the probe to be installed and update the installPackage of this record. This embodiment gives the specific form of the installation table and the specific process of installing and persisting the component to be installed based on the installation table. For easy understanding, please refer to Figure 3 , Figure 3 is a flowchart example of a status detection and persistence method provided by an embodiment of the present invention, and this flowchart corresponds to the above process. This embodiment combines the requirement of the chaos platform to reinstall the host irregularly, adds a timing detection mechanism, and can perform dynamic maintenance when it detects unavailability, ensuring the usability and reliability of the chaos platform and greatly improving the user experience.

[0122] It should be further noted that when there are new hosts and the virtual components have not been installed on the new hosts, the following steps can be included: traverse the installation table. If the current new host is connectable and the virtual components have not been installed, install the virtual components and set the information indicating whether the virtual components have been installed to "installing"; continue to traverse the next host for virtual component installation until the traversal is completed; traverse the installation table based on a set time interval. If the information indicating whether the virtual components have been installed is "installing", the value indicating whether the virtual components to be installed are connected is true, and the value indicating whether the virtual components have been started is false, then determine whether the virtual components have been installed successfully based on the first port information; if the virtual component installation is successful, set the values of whether the virtual components have been installed and whether the virtual components have been started to true, and set the value of the installation result to "success"; if the virtual components have not been installed successfully, it means that the virtual component installation has failed, then set the value of whether the virtual components have been installed to false, and set the value of the installation result to "installation failed"; continue to traverse the next new host until the traversal is completed.

The second port information in this embodiment may be the same as or different from the first port information above. The process of installing the probe in this embodiment may include: 1. Traverse the installation table; 2. If installed=true and linked=true and started=false, then start the probe and set started=starting. 3. Without waiting for the probe installation result, continue to traverse the next host until the traversal is completed; 4. Traverse the installation table; 5. If installed=true and linked=true and started=starting, determine whether the probe has been started by checking the port availability, and execute the command: telnet hostip 19527.
