[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] As container technology has become the mainstream implementation solution for PaaS (Platform as a Service) in the cloud environment, many companies or organizations use container clusters to deploy their services in the cloud environment. Depending on requirements or business differences, container clusters are sometimes deployed in different cloud environments. How to efficiently manage the life cycle of container clusters in a multi-cloud environment has become an essential task for companies or organizations.

[0046] When companies or organizations deploy container clusters in a multi-cloud environment, they will face the following problems: (1) In a multi-cloud environment, each platform and service is independent, making it difficult to centrally manage container clusters. (2) Libraries such as Boto and Fog provide local access to cloud services by using the APIs (Application Programming Interface) of cloud providers. Some libraries focus on specific clouds, while others attempt to connect them all and obscure semantic differences. These client libraries only provide low-level access to the APIs, requiring application developers to create their own tools to build and manage their container clusters. (3) Most organizations use in-house tools to help automate the mechanical processes involved in managing container clusters. These tools require time and resources to build and maintain. As essential tools, they represent the minimum viable features required by an organization and are built to handle immediate needs. Therefore, they are usually difficult to scale and maintain. (4) Open-source software such as Terraform manages resources separately for each cloud service, but does not shield the resource differences of each cloud service provider in a multi-cloud environment. Organizations or companies need to configure and manage resources for different cloud service providers themselves.

[0047] In response to this, an embodiment of the present invention provides a container cluster management system. Referring to Figure 1 , Figure 1 is a block diagram of the structure of the first embodiment of the container cluster management system provided by the present invention.

[0048] In this embodiment, the container cluster management system includes: a container cluster management component 10, a cluster orchestration image 30, and a base container cluster 20;

[0049] The container cluster management component 10 is configured to, when receiving a container cluster operation request issued by a client, determine corresponding container cluster parameters according to the container cluster operation request, and send a scheduling request to the base container cluster 20.

[0050] The container cluster management component 10 in this embodiment provides a unified API interface (application programming interface) for the client, which is used to receive container cluster operation requests sent by the client for the multi-cloud environment, convert the API requests submitted by the client according to a preset configuration language, schedule the container cluster orchestration image 30 on the base container cluster 20, and provide the client with the container cluster operation results. In a specific implementation, the container cluster management component 10 is used to manage the life cycle management of container clusters in a multi-cloud environment, including but not limited to: creating a cluster, destroying a cluster, expanding a cluster, shrinking a cluster, etc.

[0051] The base container cluster 20 is used to start the cluster orchestration image 30 in the form of a container according to the scheduling request.

[0052] It should be noted that the base container cluster 20 in this embodiment is a container cluster set on the container cluster management system, and the container cluster for executing container cluster operations is a container cluster deployed in a multi-cloud environment. In a specific implementation, when the container cluster management component 10 receives a container cluster operation request from the client, it internally schedules the cluster orchestration image 30, creates a container on the base container cluster 20, and starts the cluster orchestration image 30 in the form of a container.

[0053] The cluster orchestration image 30 is used to receive the container cluster parameters passed in by the container cluster management component 10, interact with the corresponding cloud environment according to the container cluster parameters, and execute corresponding container cluster operations in the cloud environment.

[0054] It should be understood that, optionally, the container cluster management component 10 converts the API requests submitted by the client according to a preset configuration language, submits the converted container cluster parameters to its own base container cluster 20, the base container cluster 20 passes in the container cluster parameters while creating a container, and the cluster orchestration image 30 runs in the container and receives the container cluster parameters passed in by the container cluster management component 10 through the base container cluster 20.

[0055] In another implementation, the container cluster management component 10 stores the converted container cluster parameters in a preset path, and this path is configured as the default path for the cluster orchestration image 30 to extract parameters during operation, and the cluster orchestration image 30 reads the container cluster parameters passed in by the container cluster management component 10 from the preset path.

[0056] It should be noted that the cluster orchestration image 30 in this embodiment parses the container cluster parameters, converts them into resource description files, determines the cloud environment and cloud environment driver for executing container cluster operations according to the resource description files, schedules the corresponding cloud environment driver, interacts with the corresponding cloud environment through the cloud environment driver, and executes corresponding container cluster operations in the corresponding cloud environment according to the resource description files.

[0057] It should be understood that the cluster orchestration image 30 of this embodiment can manage container clusters on one or more cloud environments simultaneously. The types of cloud environments are related to the adaptation support provided by the cluster orchestration image 30. It can monitor the operation status of the container cluster for the container cluster management component 10 to obtain the latest status information of the container cluster.

[0058] Furthermore, the container cluster management component 10 is further configured to extract container cluster metadata from the container cluster operation request, and abstractly describe the container cluster metadata according to a preset configuration language to obtain container cluster parameters.

[0059] In this embodiment, a preset configuration language (also known as: advanced configuration language) for container clusters in a multi-cloud environment is set up to uniformly and abstractly describe container cluster parameters and characteristics, including but not limited to: container cluster name, container cluster type, container cluster version, cluster control node specifications, cluster worker node specifications, number of cluster control nodes, number of cluster worker nodes, etc. By abstractly describing container cluster parameters with the preset configuration language, the differences in various cloud service resources are shielded, making the underlying details transparent to users. Refer to Table 1, which is a schematic table of the preset configuration language.

[0060] Table 1:

[0061] Field Name Field Type Field Description cluster_name String Container Cluster Name cluster_type String Container Cluster Type cluster_tag String Container Cluster Version master_flavor Object Cluster Control Node Specification worker_flavor Object Cluster Worker Node Specification infra Object Cloud Environment Information

[0062] In a specific implementation, the preset configuration language is a cluster metadata description in yaml format. A complete data representation in this embodiment is as follows:

[0063]

[0064]

[0065] Specifically, the container cluster operations include creating a container cluster, destroying a container cluster, obtaining the status of a container cluster, expanding a container cluster, and shrinking a container cluster.

[0066] Furthermore, the cluster orchestration image 30 is further configured to record the operation results corresponding to the container cluster operations according to a preset record template; the container cluster management component 10 is further configured to obtain the operation results and feedback the operation results to the client.

[0067] It should be noted that the preset record template is used to uniformly and abstractly record the life cycle of the container cluster, including but not limited to: in creation, creation successful, creation failed, in destruction, destroyed. The cluster orchestration image 30 writes the operation results in a unified format to the log service, and the container cluster management component 10 obtains the operation results corresponding to the container cluster operation requests from the log service and feeds them back to the client.

[0068] Reference Figure 2 , Figure 2 is a schematic architecture diagram of the container cluster management system provided by the present invention; the client submits a unified container cluster request through the REST API interface provided by the container cluster management component 10. Among them, the container cluster request includes the basic information of the operation. The container cluster management component 10 performs container cluster preset configuration language conversion according to the container cluster information carried in the client request, and then passes the converted container cluster parameters to the cluster orchestration image 30. When the cluster orchestration image 30 works, it uses an internal interpreter to parse the container cluster parameters, and then calls the executor to interact with the cloud environment to execute the container cluster operation in the cloud environment.

[0069] The system proposed in this embodiment includes a container cluster management component, a cluster orchestration image, and a container cluster; when the container cluster management component receives a container cluster operation request issued by the client, it determines the corresponding container cluster parameters according to the container cluster operation request, and sends a scheduling request to the container cluster; the container cluster starts the cluster orchestration image in the form of a container according to the scheduling request; the cluster orchestration image receives the container cluster parameters sent by the container cluster management component, interacts with the corresponding cloud environment according to the container cluster parameters, and executes the corresponding container cluster operation in the cloud environment. Through the above method, the container cluster management component is used to manage the entire life cycle of the container cluster in the multi-cloud environment. The container cluster starts the cluster orchestration image under the scheduling of the container cluster management component. The cluster orchestration image selects the corresponding cloud environment from the multi-cloud environment according to the container cluster parameters to interact and execute the corresponding container cluster operation, realizing the unified management of the container cluster in the multi-cloud environment.

[0070] Based on the above embodiment, Figure 3 is a schematic flowchart of the second embodiment of the container cluster management method provided by the present invention;

[0071] As Figure 3 shown, the container cluster management component 10 is further configured to provide application program interfaces 40 corresponding to different container cluster operations to the client, and receive the container cluster operation request issued by the client based on the application program interface 40.

[0072] In a specific implementation, an API (application program interface 40) is provided in a unified abstract format for the client to call; preferably, the API can be a REST API or a Web Service; the application program interfaces 40 corresponding to different container cluster operations include: an API for creating a container cluster in the cloud environment; an API for destroying a container cluster in the cloud environment; an API for obtaining the status of a container cluster; preferably, an API for expanding a container cluster in the cloud environment; preferably, an API for shrinking a container cluster in the cloud environment.

[0075] The cluster orchestration image 30 is further configured to interact with a corresponding target cloud environment according to the received target container cluster parameters, and perform a corresponding target container cluster operation in the target cloud environment.

[0076] It should be noted that the container cluster management component 10 in this embodiment can schedule a plurality of cluster orchestration images 30 at the same time, allocate the target container cluster parameters corresponding to each target container cluster operation request to different cluster orchestration images 30, and each cluster orchestration image 30 starts a corresponding cloud environment driver 70 according to the obtained target container cluster parameters, interacts with the corresponding target cloud environment, and performs the target container cluster operation corresponding to the target container cluster operation request.

[0077] Refer to Figure 4 , Figure 4 is a schematic diagram of the container cluster management component of the container cluster management system provided by the present invention; the container cluster management component 10 in this embodiment is a Java middleware developed using Spring Boot technology, which provides an access interface to the user side in the form of a REST API, and mainly includes:

Through the above method, the container cluster management component provides a unified and abstract application program interface to the client, eliminates the burden of building tools, receives container cluster operation requests through the application program interface, invokes the container cluster to start the cluster orchestration image, and the cluster orchestration image selects the corresponding cloud environment from the multi-cloud environment according to the container cluster parameters for interaction and executes corresponding container cluster operations, realizing the unified management of the container cluster in the multi-cloud environment, and the container cluster infrastructure is code.
