Description

Technical Field

[0001] The present invention relates to the field of cloud resource synchronization technology; in particular, to a CMDB cloud resource synchronization method and system. Background Art

[0002] Cloud Resource Synchronization refers to the key operation in a cloud computing environment to ensure the consistency of resources and data between different cloud environments, different regions, and different services. Cloud resource synchronization can involve a variety of resource types, including storage, databases, virtual machines, configuration files, etc. Cloud resource synchronization includes the following situations: 1. Data synchronization, maintaining data consistency between different storage locations. This usually involves copying data from one location to another and ensuring that the data in the two locations remains synchronized.

[0003] 2. Configuration synchronization, maintaining consistency of configuration files between different environments or services. This is very important to ensure consistent behavior between different environments (such as development, testing, and production).

[0004] 3. Application synchronization to maintain consistency of application state and code between different locations or service instances.

[0005] The traditional cloud resource synchronization method is mainly to synchronize the host resources and cloud region information on the cloud platform in one direction through API keys. However, the existing cloud resource synchronization method has the disadvantages of untimely cloud resource management and inaccurate information, which increases the manpower maintenance cost and low cloud resource synchronization efficiency. Summary of the invention

[0006] In view of this, the purpose of the present invention is to consider factors such as data consistency, delay, cost and security when implementing cloud resource synchronization, and to correctly obtain the list of virtual machine resources by efficiently calling the third-party cloud computing platform API, so as to realize the scheduled automatic execution of resource discovery operations and achieve efficient resource synchronization, so as to solve the problems of untimely updates and inaccurate information in traditional cloud resource management, reduce manpower maintenance costs, improve cloud resource synchronization efficiency, and improve the reliability, availability and consistency of the system.

[0007] The present invention provides a CMDB cloud resource synchronization method, comprising the following steps: S1. Obtain the access key and secret key of the project that the operation management wants to access, and perform authentication and authorization of the API call; S2. Use the Go language to write code and use the Go SDK toolkit (preferably the Go SDK toolkit of Huawei Cloud) to make API calls. Obtain the list of virtual machine resources through API calls and obtain virtual machine resource data through the Go SDK toolkit. S3. Map the acquired virtual machine resource data to the data model of the configuration management database CMDB and store it in the database of the CMDB; use the ORM library of the Go language (such as "GORM") to perform database operations; S4. Use the Go language scheduled task library (such as "github.com / robfig / cron") to automatically perform virtual machine resource discovery operations at regular intervals.

[0008] Furthermore, the step S2 includes the following steps: S21. Import the fmt package in the Go language standard library, the core package of the Huawei Cloud SDK, and the SDK package of the Elastic Cloud Server ECS service; S22. Use the huaweicloud.NewClient function to pass in the configuration information including AK, SK, Region, and ProjectID to create a Huawei cloud client. S23. Use the created Huawei Cloud client to call the ecs.NewEcsClient function to create an ECS client. If an error occurs during the creation of the ECS client, the error message is printed and the program exits; If no error occurs during the creation of the ECS client, proceed to step S24; S24. Define an instance of the ecs.ListServersDetailsOpts structure to specify query conditions (such as filter conditions, etc.); S25. Call the ecs.ListServersDetails function, pass in the ECS client and query options, and obtain the server list; If an error occurs while querying the server list, an error message is printed and the program exits; If no error occurs during the query of the server list, proceed to step S26; S26. Traverse the server list in the query result and print the unique ID identifier and name of each server (more attributes can be printed as needed).

[0009] Furthermore, the S3 step includes the following steps: S31. Import the gorm.io / driver / mysql package to use the MySQL database driver; import the gorm.io / gorm package to use the object-relational mapping (ORM) function of the GORM library; S32. Define a structure named VirtualMachine as the data model of the virtual machine; embed the gorm.Model function in the VirtualMachine structure, which contains the commonly used fields: ID, creation time, update time, and deletion time; define the ID and Name fields as the unique identifier and name of the virtual machine respectively; in addition, other required attributes can be defined; S33, defining a main function main, the entry point of the program, in which database connection and data model migration are performed; S34. Define the database connection string dsn in the format of: username:password@tcp(host address:port) / database name?parameter; for example: "user:password@tcp(localhost:3306) / dbname?charset=utf8mb4&parseTime=True&loc=Local"; S35. Use the gorm.Open function, pass in the MySQL driver and connection string, and try to establish a connection with the database; If the connection fails, print an error message and exit the program; If the connection is successful, proceed to step S36; S36. Call the db.AutoMigrate method, pass in the VirtualMachine structure, and automatically migrate the database table structure to ensure that the database table is consistent with the data model; S37. Obtain virtual machine resource data from Huawei Cloud, and store the virtual machine resource data in a database.

[0010] Furthermore, the S4 step includes the following steps: S41. Import the github.com / robfig / cron package and use the scheduled task scheduling function provided by the github.com / robfig / cron package; S42, defining the main function main, the entry point of the program, in which the scheduled tasks are set and scheduled; S43, calling cron.New method to create a new scheduled task scheduler instance c, wherein the scheduled task scheduler instance c is used to manage and schedule scheduled tasks; S44. Use the c.AddFunc method to add a scheduled task, configure its scheduling time and task function, and execute the task once every hour (for example, the scheduling time "0 0 * * * *" means running the task at the 0th minute of every hour); in the task function, place the logic of the resource discovery operation that needs to be executed regularly; S45, calling the c.Start method to start the scheduled task scheduler, so that the scheduled task scheduler starts scheduling tasks according to the set time; S46. Use the defer keyword and call the c.Stop() method before the program exits to stop the scheduled task scheduler and perform necessary resource cleanup. Use the select {} statement to block the main function to keep the program running and ensure continuous execution of the scheduled task.
