Currently, when a virtual cluster is created by using a Kubemark, the virtual cluster is created by manually executing a script of the Kubemark, and the method has certain complexity, so that the efficiency of creating the virtual cluster is reduced.

In order to solve the above technical problems, in the virtual cluster creation method provided in the embodiments of the present application, when a creation instruction for creating a virtual cluster for at least one physical cluster is received, configuration files of each physical cluster are respectively determined; and then creating virtual clusters corresponding to the physical clusters according to configuration information contained in the configuration files of the physical clusters. By the method, the virtual clusters corresponding to the physical clusters can be created through the configuration information contained in the configuration files of the physical clusters, and the creation of the script of the Kubemark is not needed to be manually executed, so that the efficiency of creating the virtual clusters can be effectively improved.

Fig. 3 is a flowchart of a virtual cluster creation method according to an embodiment of the present application, as shown in fig. 3, where the method includes the following steps:

in step S301, when a creation instruction for creating a virtual cluster for at least one physical cluster is received, configuration files of the physical clusters are respectively determined.

Specifically, the server may receive, through a controller cluster in which a controller is deployed in advance, a creation instruction for creating a virtual cluster for at least one physical cluster, which is sent by a user through a terminal device, and after receiving the creation instruction, determine a configuration file of each physical cluster according to a cluster identifier of a corresponding physical cluster included in each creation instruction. The configuration file may be preset in the controller cluster.

In the embodiment of the present application, the configuration file may be stored in a CRD (Custom ResourceDefinition, custom resource) format, which is not limited in this application.

In the embodiment of the present application, the controller cluster in which the controller is pre-deployed may be a physical cluster that needs to create a virtual cluster, or may be any physical cluster except a physical cluster that needs to create a virtual cluster, but when the controller cluster is any physical cluster except a physical cluster that needs to create a virtual cluster, the controller cluster and the physical cluster that needs to create a virtual cluster may communicate through a network.

In one embodiment, the process of deploying the controller in the K8s cluster belongs to the process of deploying the controller in the containerized scene, so that the controller can be deployed by one key by using yaml files according to the related mirror images of the deployment controller in the containerized scene, and corresponding development resources, CRD and RBAC (Role-based access control) resources are generated in the deployment process.

Step S302, creating virtual clusters corresponding to the physical clusters according to configuration information contained in the configuration files of the physical clusters.

Specifically, after the configuration information contained in the configuration file of each physical cluster is determined, the configuration information contained in the configuration file of each physical cluster may be sent to the corresponding physical cluster, and the virtual cluster corresponding to each physical cluster is created through the control component contained in each physical cluster.

By the method, when the virtual clusters are created by utilizing the Kubemark, the virtual clusters corresponding to the physical clusters can be automatically created directly through the configuration information contained in the configuration files of the physical clusters, and the user does not need to manually execute the script of the Kubemark for creation, so that the efficiency of creating the virtual clusters can be effectively improved.

In an alternative embodiment, the configuration file of each physical cluster may include physical configuration information and virtual configuration information corresponding to each physical cluster. Accordingly, in performing the above step S302, reference may be made to the method illustrated in fig. 4, which may include, as illustrated in fig. 4, the steps of:

step S401, respectively obtaining control components of each physical cluster according to the physical configuration information of each physical cluster.

Specifically, in an alternative embodiment, the physical configuration information may include an address identifier and an access identifier, the server may obtain physical configuration information of each physical cluster from the controller cluster, and after obtaining the physical configuration information of each physical cluster, may establish connection with a corresponding physical cluster through the controller cluster according to the address identifier included in the physical configuration information of each physical cluster, and obtain a control component of the physical cluster according to the access identifier included in the physical configuration information.

In this embodiment of the present application, the address identifier may include, but is not limited to, a cluster control plane address corresponding to the physical cluster, and the access identifier may include, but is not limited to, a token (flag) corresponding to a service account number of the physical cluster.

In this embodiment of the present application, before executing step S401, that is, before acquiring the control components of each physical cluster according to the physical configuration information of each physical cluster, a service account may be created in advance for each physical cluster that needs to create a virtual machine group.

Specifically, when a user creates a service account, a service account may be created in a physical cluster where a virtual cluster needs to be created, and the service account is bound with a cluster-admin (cluster role), after detecting that the user binds the service account and the cluster-admin, the server may obtain a token of the corresponding service account, and the controller cluster may reduce the operable authority of the controller cluster to the corresponding physical cluster through the token of the service account.

In this embodiment of the present application, the physical configuration information of each physical cluster may further include information such as a name space name of each physical cluster, a secret name for connecting to a control plane, and the like, which is not limited in this application.

Step S402, based on the virtual configuration information corresponding to each physical cluster, and through the control components of each physical cluster, virtual clusters corresponding to each physical cluster are respectively created.

Specifically, after the connection is established between the controller cluster and the corresponding physical cluster, a virtual cluster creation request can be sent to each physical cluster through the controller cluster, virtual configuration information corresponding to each physical cluster is sent to the corresponding physical cluster through the controller cluster, and after the physical cluster receives the virtual configuration information, the corresponding virtual cluster can be created through the control component according to the virtual configuration information.

In the embodiment of the present application, the virtual configuration information may include a cluster name of the virtual cluster and the number of virtual nodes. For example, assuming that the first physical cluster is a physical cluster in which a virtual machine group needs to be created, the virtual configuration information corresponding to the first physical cluster may include a cluster name of the virtual cluster corresponding to the first physical cluster and the number of virtual nodes included in the virtual cluster corresponding to the first physical cluster. For example, the node prefix, the number of groups, and the number of virtual nodes included in each group of virtual nodes included in the virtual cluster corresponding to the first physical cluster.

In an alternative embodiment, the statefulset resource controller may be used in creating virtual clusters corresponding to each physical cluster by the control component of each physical cluster, because the names of virtual nodes created by the statefulset resource controller are ordered, and when a virtual node fails and needs to be rebuilt, original name information is still reserved, and dirty data is not generated in reconnecting to the clusters.

In an optional embodiment, in step S302, when creating virtual clusters corresponding to each physical cluster according to configuration information included in the configuration file of each physical cluster, each virtual node included in the virtual cluster corresponding to each physical cluster may be sequentially created to obtain a current virtual node, and the following steps are performed on the current virtual node:

acquiring node registration information corresponding to a current virtual node; if the node registration information of the current virtual node is consistent with the node running state of the current virtual node, creating a next virtual node; if the node registration information of the current virtual node is inconsistent with the node running state of the current virtual node, deleting the current virtual node and re-creating until the node registration information of the current virtual node is consistent with the node running state of the current virtual node; namely, deleting the current virtual node and re-creating the current virtual node in response to the fact that the node registration information of the current virtual node is inconsistent with the node running state of the current virtual node. The node registration information is that the current virtual node is registered in the corresponding physical cluster.

In an optional implementation manner, after the virtual clusters corresponding to the physical clusters are created, configuration information contained in configuration files of the physical clusters may be detected, an operation of updating the configuration information contained in the configuration file of any physical cluster may be responded, and node information of each virtual node contained in the virtual cluster corresponding to the physical cluster is updated according to the updated configuration information. Wherein, the configuration information generation update can comprise addition, deletion, modification and the like of the virtual node.

In an exemplary embodiment, when a user intends to delete a virtual cluster corresponding to any physical cluster, the user may delete a configuration file of the physical cluster included in the controller cluster, and when the server detects that the configuration file is deleted through the controller cluster, the server may delete virtual nodes (pod) included in a virtual machine group corresponding to the physical cluster, and delete virtual data corresponding to each virtual node after the deletion is completed, that is, delete virtual node dirty data corresponding to each virtual node.

By the method, when any virtual cluster needs to be deleted, each virtual node contained in the virtual cluster and virtual node dirty data corresponding to the virtual node can be automatically deleted without manual deletion by a user.
