[0045] Figure 1 FIG. 1 is a flow chart of some embodiments of the edge cluster system deployment method according to the present disclosure. Figure 1 As shown, the deployment method of the edge cluster system includes steps S101-S104.

[0046] Step S101 : using a first application image of an edge cluster component, create and start an edge cluster application container in a container cluster management system.

[0047] The container cluster management system provides centralized management, scheduling, and monitoring functions for software tools or platforms that manage and run container clusters. The container cluster management system can be a variety of systems, such as a K8s system. The edge cluster system can be a variety of systems, such as a K8s edge cluster system. The edge cluster components can be a variety of systems, such as an edge cluster component of a K8s system.

[0048] The first application image of the edge cluster component can be a variety of images. An image is a special file system that contains the programs, libraries, resources, configurations, and other files required for the container to run. The image also contains the configuration parameters required for runtime (such as environment variables, etc.). The image does not contain dynamic data, and the image content will not be changed after it is built.

[0049] Pod is the smallest basic unit for deployment and management in the container cluster management system. In the container cluster management system, an edge cluster application container is created and started. The edge cluster application container is an instance of an independently running application or service. The edge cluster application container can run in a Pod.

[0050] Step S102: Use the second application image of the edge component to create and start an edge component application container in the container cluster management system.

[0051] There may be multiple edge components, such as edge components of a K8s system. The second application image of the edge component may be multiple images. An edge component application container is created and started in a container cluster management system. The edge component application container is an instance of an independently running application or service. The edge component application container may run in a Pod.

[0052] Step S103: Start the data storage service container in the container cluster management system.

[0053] The data storage service container is used to provide data storage services for edge cluster application containers and edge component application containers. The edge cluster application containers and edge component application containers use the data storage service container to store data and achieve data persistence; the edge cluster application containers and edge component application containers can also obtain their own stored data through the data storage service container after restarting.

[0054] The data storage service container can be of various types, such as the distributed key-value storage service ETCD container. ETCD is a distributed key-value storage system that can provide reliable storage and access data services. The distributed characteristics of ETCD can ensure that the entire ETCD system can still operate normally when some nodes are down.

[0055] By starting the ETCD container in the container cluster management system, the edge cluster application container and the edge component application container can access the ETCD container to store data, and can access the stored data by accessing the ETCD container; the ETCD container can store data in the ETCD database.

[0056] Step S104: forwarding messages between edge nodes and edge cluster application containers using a load balancing LB (Load Balance) device of the container cluster management system.

[0057] The edge node can be a node in a system such as an edge cloud system, and the LB device provides a network service portal to the edge node. The access information of the edge cluster application container can be configured in the LB device, and the messages between the edge node and the edge cluster application container can be forwarded through the LB device.

[0058] The edge cluster system deployment method disclosed in the present invention creates and starts an edge cluster application container and an edge component application container in a container cluster management system by using an application image, starts a data storage service container in the container cluster management system, and uses a load balancing device to forward messages between edge nodes and edge cluster application containers. This allows the edge cluster to run in the container cluster management system as an application, without the need to use a new virtual machine device to run the edge cluster system, thereby reducing the operation and maintenance cost of the edge cluster system; the edge cluster system can be expanded, reduced, and managed by expanding, reducing, and managing the application, thereby simplifying the deployment, expansion, and reduction processes of the edge cluster system, reducing the complexity of the operation and maintenance and management of the edge cluster system, and improving the efficiency of the operation and maintenance and management of the edge cluster system.

[0059] A first application image may be generated based on a binary file of an edge cluster component. For example, a binary file of an edge cluster component may be obtained, and a first application image may be generated based on the binary file and using an image generation script. The first application image may be a docker image, etc. A second application image may be generated based on a binary file of an edge component. For example, a binary file of an edge cluster component may be obtained, and a second application image may be generated based on the binary file and using an image generation script. The second application image may be a docker image, etc.

[0060] The edge cluster components include API (Application Programming Interface) service components, which can be kube-apiserver components, etc. The API service components are used to provide API interfaces for edge cluster management, data interaction and communication services, etc.

[0061] The first application image includes an API service application image of an API service component. The API service application image may be an application image of a kube-apiserver component, etc. The edge cluster application container includes an API service application container. The API service application container may be a kube-apiserver application container, etc.

[0062] You can use the API service application image to create and start the API service application container in the container cluster management system. Figure 2 The following is a flow chart of starting an API service application container in some embodiments of the edge cluster system deployment method according to the present disclosure. Figure 2 As shown, the method for starting the API service application container includes steps S201-S204.

[0063] Step S201, add the domain name information of the API service component and the issuance information of the LB device to the certificate file of the API service component.

[0064] You can use a variety of commands to generate the certificate file of the API service component. The certificate file is a digital file used to verify the identity of the API service. Apply for the domain name information of the API service component and obtain the issuance information of the LB device. Add the domain name information of the API service component and the issuance information of the LB device to the certificate file of the API service component. The domain name information of the API service component includes the service name, namespace, and the domain name suffix in the container cluster management system where the service is located. The issuance information of the LB device includes the serial number of the LB device, manufacturer information, issuance date, validity period, and possible security certification identification.

[0065] Step S202: Add the address information and the trust certificate of the data storage service container to the configuration file of the API service component.

[0066] The address information and CA certificate of data storage service containers such as ETCD container can be added to the configuration file of the API service component. Based on the address information and the trust certificate, the API service application container can use the data storage service to store data in the data storage service container. For example, the address information of the ETCD container is the access address information. Based on the address information and CA certificate of the ETCD container, the API service application container can access the ETCD container to store and access data.

[0067] Step S203: Use the API service application image and based on the configuration file and the certificate file to create and start the API service application container, and enable the API service application container to open the API access service.

[0068] In some embodiments, the Deployment in K8s is a declarative resource object that can use the API service application image and based on the configuration file and certificate file, use the existing Deployment method to create and start the API service application container, which is a stateless application.

[0069] The type of API access service opened by the API service application container is NodePort. A static port can be assigned to the API service application container and exposed on all nodes. Other containers can access the API service application container through the address + port of the API service application container.

[0070] Step S204: adding the access information of the API access service to the encrypted object of the API service application container.

[0071] The encrypted object can be a Secret object in K8s, etc. The Secret object in K8s is used to securely store and manage sensitive information, ensuring that the information is securely managed and distributed to the required containers within the cluster. You can use a variety of methods to generate the encrypted object (K8s Secret object) of the API service application container. The access information of the API access service can be configured in the kubeconfig file. The access information of the API access service or the kubeconfig file can be added to the encrypted object of the API service application container.

[0072] In some embodiments, the edge cluster component includes a controller management component, which may be a Kube-Controller-Manager component, etc. The controller management component is responsible for maintaining the consistency between the desired state and the actual state of the edge cluster system. The first application image includes a controller management application image, such as a Kube-Controller-Manager application image; the edge cluster application container includes a controller management application container, such as a Kube-Controller-Manager application container.

[0073] Figure 3 The following is a flow chart of the startup controller managing the application container in some embodiments of the edge cluster system deployment method according to the present disclosure. Figure 3 As shown, the method for starting a controller to manage an application container includes steps S301-S302.

[0074] Step S301: Use the controller to manage the application image, create and start the controller to manage the application container.

[0075] You can use the controller to manage application images and use the Deployment method to create and start the controller-managed application container, which is a stateless application.

[0076] Step S302: Based on the encrypted object, configure first access information corresponding to the API access service for the controller management application container.

[0077] When the controller management application container is created and started in the Deployment mode, the access information of the API access service can be obtained by loading the encrypted object of the API service application container. Based on the access information of the API access service, the first access information corresponding to the API access service can be configured for the controller management application container, and the first access information can be information such as the address + port of the API service application container.

[0078] After the controller management application container is started, the controller management application container uses the API access service to store the data of the controller management application container based on the first access information, wherein the API access service stores the data of the controller management application container in the data storage service container by using the data storage service.

[0079] For example, after the controller management application container is started, the controller management application container uses the API access service opened by the API service application container based on the address + port and other information of the API service application container to store the data of the controller management application container and obtain the previously stored data of the controller management application container.

[0080] In some embodiments, the edge cluster component includes a scheduling component, which may be a kube-scheduler component, etc. The kube-scheduler component is used to allocate containers to be scheduled to run on appropriate nodes; the kube-scheduler component works in conjunction with the kube-apiserver component and the kube-controller-manager component to ensure the normal operation of the edge cluster. The first application image includes a scheduling application image, such as an application image of the kube-scheduler component, etc.; the edge cluster application container includes a scheduling application container, such as a kube-scheduler application container, etc.

[0081] Figure 4 FIG. 1 is a flow chart of starting and scheduling application containers in some embodiments of the edge cluster system deployment method according to the present disclosure. Figure 4 As shown, the method for starting the scheduling application container includes steps S401-S302.

[0082] Step S401: Use the scheduling application image to create and start a scheduling application container.

[0083] You can use the scheduling application image and use the Deployment method to create and start the scheduling application container. The scheduling application container is a stateless application.

[0084] Step S402: Based on the encrypted object, second access information corresponding to the API access service is configured for the scheduling application container.

[0085] When the Deployment method is used to create and start the scheduling application container, the access information of the API access service is obtained by loading the encrypted object of the API service application container; based on the access information of the API access service, the second access information corresponding to the API access service is configured for the scheduling application container. The second access information can be the address + port and other information of the API service application container.

[0086] After the scheduling application container is started, the scheduling application container uses the API access service to store data of the scheduling application container based on the second access information, wherein the API access service stores the data of the scheduling application container in the data storage service container by using the data storage service.

[0087] For example, after the scheduling application container is started, the scheduling application container uses the API access service opened by the API service application container based on the address + port and other information of the API service application container to store the data of the scheduling application container and obtain the previously stored data of the scheduling application container.

[0088] In some embodiments, edge components refer to components located at the edge of the network in the edge planning architecture, which are used to process data of edge nodes, etc. Edge components may include service components for managing edge node autonomy, service components for managing edge application expansion and contraction, service components for collecting edge application logs, components for providing coreDNS services, and other components to provide multiple services for edge nodes.

[0089] Figure 5 FIG. 1 is a flow chart of starting an edge component application container in some embodiments of the edge cluster system deployment method according to the present disclosure. Figure 5 As shown, the method for deploying and starting the edge component application container includes steps S501-S502.

[0090] Step S501: Use the second application image to create and start an edge component application container.

[0091] The second application image can be used, and the edge component application container can be created and started in a deployment manner. The edge component application container is a stateless application.

[0092] Step S502: Based on the encrypted object, configure third access information corresponding to the API access service for the edge component application container.

[0093] When the edge component application container is created and started using the Deployment method, the access information of the API access service can be obtained by loading the encrypted object of the API service application container; based on the access information of the API access service, the third access information corresponding to the API access service is configured for the edge component application container. The third access information can be the address + port and other information of the API service application container.

[0094] After the edge component application container is started, the edge component application container uses the API access service to store data of the edge component application container based on the third access information, wherein the API access service stores the data of the edge component application container in the data storage service container by using the data storage service.

[0095] For example, after the edge component application container is started, based on the address + port and other information of the API service application container, the API service application container uses the API access service open to store the data of the edge component application container, and can obtain the previously stored data of the edge component application container.

[0096] In some embodiments, in a container cluster management system, a data storage service container is started in a stateful set manner, and the data storage service container is configured to open the data storage service in a headless service manner.

[0097] The data storage service container is a stateful service application; the stateful set mode can be Statefulset mode, which is a K8s resource object used to manage stateful applications, containers, etc. The headless service mode is the Headless Service mode. The Headless Service mode is a service mode in K8s. The Headless Services mode does not maintain a virtual IP (VIP) to proxy and load balance to the backend Pod. Compared with the non-Headless Services mode, the Headless Services mode does not provide load balancing and a single access entry point, and directly forwards service requests to the backend Pod.

[0098] In the load balancing LB device of the container cluster management system, the address information of the API service application container is configured so that the LB device forwards the first message sent by the edge node to the API service application container based on the API service application container address information, and returns the second message sent by the API service application container to the edge node.

[0099] For example, in the K8s system, you can apply for a LB device, configure the address information of the API service application container in the LB device, and open the address information of the LB device. The address information of the API service application container can be address + port and other information. The edge node accesses the edge cluster system through the LB. The edge node can send a first message to the LB device based on the address information of the LB device. The first message can be a variety of messages; the LB device forwards the first message sent by the edge node to the API service application container based on the address information of the API service application container.

[0100] The API service application container can process the first message, or send the first message to other containers for processing. The API service application container sends the second message to the LB device. The second message can be a variety of messages. The second message can be a message generated by the API service application container or a message generated by other containers. The LB device returns the second message to the edge node.

[0101] When there are multiple API service application containers, the LB device can perform load balancing; the LB device can select an API service application container from multiple API service application containers through an existing load balancing algorithm to provide services to the edge node.

[0102] like Figure 6As shown, an edge cluster system 61 is deployed in the container cluster management system 60, and the edge cluster system 61 includes an edge cluster application container 62 and an edge component application container 63; the edge cluster application container 62 includes an API service application container 621, a controller management application container 622 and a scheduling application container 623, etc.

[0103] A data storage service container 64 is started in the container cluster management system 60. The data storage service container 64 is used to provide data storage services for the edge cluster application container 62 and the edge component application container 63. The edge cluster system 61 is in namespace 1, and the data storage service container 64 is in namespace 2.
