[0034] Under the above operating environment, this application provides Figure 2 A method for processing a container group instance is shown. Figure 2 is a flowchart of a method for processing a container group instance according to an embodiment of the present application, such as Figure 2 As shown, the method for processing the container group instance includes:

[0035] Step S202, receiving a control command from the serverless container orchestration system, wherein the control command is used to call an elastic container instance on the cloud platform to create a container group instance and to create a persistent storage volume resource on an elastic block storage device;

[0036] Step S204: creating the container group instance and the persistent storage volume resource according to the control command;

[0037] Step S206: Use a persistent storage volume declaration method to persistently store the data generated by the container group instance in the persistent storage volume resource.

[0038] In an embodiment of the present application, based on compliance with the K8S system's usage specifications for persistent storage volume declaration PVC, a control command is received from a serverless container orchestration system, wherein the control command is used to call an elastic container instance on a cloud platform to create a container group instance and to create a persistent storage volume resource on an elastic block storage device; the container group instance and the persistent storage volume resource are created in accordance with the control command; and the data generated by the container group instance is persistently stored in the persistent storage volume resource using a persistent storage volume declaration method.

[0039] Based on the embodiment of the present application, the cloud platform receives the control command issued by the cloud disk controller DiskController in the serverless container orchestration ASK system, and calls the elastic container instance on the cloud platform according to the control command through the elastic container instance management and control system to create a container group instance and a persistent storage volume PV resource on the elastic block storage device EBS, and uses the persistent storage volume declaration PVC method to persistently store the data generated by the container group instance in the persistent storage volume PV resource, thereby achieving the purpose of persistently storing the data generated by the ECI container group instance in the persistent storage volume PV resource created by the elastic block storage device EBS by the persistent storage volume declaration PVC method, thereby providing persistent storage capabilities for user business data of the cloud platform.

[0040] Therefore, the embodiment of the present application achieves the purpose of realizing persistent storage volume declaration based on a serverless container orchestration system, thereby achieving the technical effect of providing persistent storage capabilities for user business data of the cloud platform, and further solving the technical problem in the prior art that the serverless container orchestration system does not support persistent storage volume declaration and cannot provide persistent storage capabilities for user business data of the cloud platform.

[0041] It should be noted that the execution subject of the embodiment of the present application is a cloud platform. Optionally, the serverless container orchestration system may be a Serverless Kubernetes system, namely, an ASK system; the elastic block storage device may be an elastic block storage device EBS; the elastic container instance may be an elastic container instance ECI; the relationship diagram between the serverless container orchestration ASK system and the elastic container instance ECI may be, but is not limited to, as follows: Figure 3 As shown, a communication connection is established between the serverless container orchestration ASK system and the elastic container instance ECI.

[0042] As an optional embodiment, receiving the control command from the serverless container orchestration system includes:

[0043] Receive a command to create a container group from a virtual node in the serverless container orchestration system;

[0044] Receive a command to create a cloud disk from a cloud disk controller in the serverless container orchestration system.

[0045] In the above optional embodiments, the serverless container orchestration ASK system can specifically send a create container group command to the cloud platform through a virtual node, so as to call the elastic container instance on the cloud platform to create a container group instance according to the create container group command; and the serverless container orchestration ASK system can specifically send a create cloud disk command to the cloud platform through a cloud disk controller DiskController, so as to create a persistent storage volume resource on the elastic block storage device of the cloud platform according to the create cloud disk command.

[0046] It should be noted that the optional or preferred container group instance processing method embodiments in the embodiments of the present application can be applied to, but not limited to, the following application scenarios: ASK system users want to use the elastic block storage device EBS by declaring PVCs of persistent storage volumes to provide persistent storage capabilities for business data.

[0047] In an optional container group instance processing method embodiment provided in an embodiment of the present application, based on complying with the K8S system's use specification for persistent storage volume declaration PVC, in order to solve the technical problem that the current ASK system does not support persistent storage volume declaration PVC in the prior art, the following innovative designs are mainly performed:

[0048] In an optional embodiment, Figure 4 As shown, by adding a custom cloud disk controller DiskController in the ASK system, the main function of the cloud disk controller DiskController is to send a create cloud disk command to the cloud platform to dynamically create a persistent storage volume resource on the elastic block storage device of the cloud platform according to the create cloud disk command; the main function of the virtual node in the above ASK system is to send a create container group command to the cloud platform to realize the automatic creation of a container group instance by calling the elastic container instance on the cloud platform according to the create container group command.

[0049] Optionally, the cloud disk controller DiskController may respond to a user's operation request for declaring a persistent storage volume PVC based on the storage type StorageClass as a filtering condition, and call the elastic block storage device EBS based on the operation request to create or delete persistent storage volume resources.

[0050] In an optional embodiment, creating the container group instance according to the control command includes:

[0051] Step S302: In response to the control command, the container group instance is created through the elastic container instance management and control system and a cloud disk type storage volume is mounted to the container group instance;

[0052] Step S304: format the cloud disk type storage volume through the elastic container instance agent in the container group instance and mount it to the elastic block storage device.

[0053] Optionally, the control command for creating a container group instance is a container group creation command issued by a virtual node. In the process of creating the container group instance according to the container group creation command, the cloud platform responds to the container group creation command, creates the container group instance through the elastic container instance ECI management and control system, and mounts the cloud disk type storage volume to the container group instance, that is, the embodiment of the present application can complete the mounting and unmounting operations of the cloud disk type storage volume in the ECI management and control system, and the elastic container instance agent (that is, the ECI-Agent component) in the container group instance does not need to care about the mounting and unmounting of the cloud disk type storage volume, and only performs the operation of formatting the cloud disk type storage volume and mounting it to the elastic block storage device.

[0054] In the above optional embodiment, a container orchestration system storage plug-in is integrated into the above elastic container instance agent, wherein the above container orchestration system storage plug-in supports at least one of the following functions:

[0055] Under the control of the elastic container instance management and control system, format the cloud disk type storage volume.

[0056] Under the control of the elastic container instance management system, a mount operation is performed on the cloud disk type storage volume;

[0057] Under the control of the elastic container instance management and control system, an unmount operation is performed on the cloud disk type storage volume.

[0058] As another optional embodiment, the elastic container instance agent ECI-Agent component also integrates a container orchestration system storage plug-in (i.e., a Kubernetes storage plug-in), for example Figure 4 The FlexVolume plug-in shown in the figure, wherein the ECI-Agent component deployed in the ECI management system supports the formatting operation Format, the mounting operation Mount and the unmounting operation Umount for the cloud disk by integrating the FlexVolume plug-in, and implements all interfaces of the FlexVolume plug-in in combination with the ECI management system's attachment operation Attach and separation operation Detach for the cloud disk.

[0059] Through the above optional embodiments of the present application, under the premise of ensuring the native architecture of the unified K8S system, the operations of mounting, unmounting and formatting are separated, and the ECI-Agent component does not need to introduce the access key ID (Access Key ID, AK) and the key (Secret Access Key, SK) used in combination with the access key ID.

[0060] In an optional embodiment, creating the container group instance through the elastic container instance management and control system and mounting the cloud disk type storage volume to the container group instance includes:

[0061] Step S402, expanding the storage volume types supported by the application program interface of the elastic container instance management and control system, and adding the cloud disk type storage volume;

[0062] Step S404: The elastic container instance management and control system calls the elastic cloud server interface to create the container group instance.

[0063] Step S406: Based on the storage volume identifier of the cloud disk type storage volume, the elastic container instance management and control system calls the elastic cloud server interface to mount the cloud disk type storage volume to the container group instance.

[0064] In the embodiments of the present application, Figure 4 The elastic container instance management and control system (i.e., ECI management and control system) shown supports the cloud disk function. The ECI management and control system is extended by extending the storage volume types supported by the application API interface to add cloud disk type storage volumes. In the process of creating an ECI container group instance, the ECI management and control system first calls the elastic cloud server interface (i.e., ECS interface) provided by the elastic cloud server ECS to create a container group instance, and then, according to the storage volume identifier VolumeID of the cloud disk type storage volume pre-set by the user, the ECI management and control system calls the above ECS interface to mount the cloud disk type storage volume corresponding to the storage volume identifier to the container group instance.

[0065] In the above optional embodiment of the present application, a custom cloud disk controller DiskController is used, and the cloud disk controller DiskController implements interaction with the elastic block storage device EBS according to the addition, deletion, modification and query of the persistent storage volume declaration PVC, and correspondingly implements the addition, deletion, modification and query of the persistent storage volume PV resources. Based on the cloud disk controller DiskController, the corresponding persistent storage volume PV resources can be flexibly operated according to the operation status of the persistent storage volume declaration PVC, shielding the interaction process between the user and the elastic block storage device EBS, reducing the user's learning cost, that is, the user only needs to pay attention to the use of the ASK system.

[0066] In an optional embodiment, the method further includes: if formatting of the cloud disk type storage volume fails or mounting of the cloud disk type storage volume fails by calling the container orchestration system storage plug-in in the elastic container instance agent, an alarm prompt message is issued.

[0067] In the above optional embodiments, since the embodiment of the present application is provided with a FlexVolume plug-in in the elastic container instance agent ECI-Agent component to implement calling the FlexVolume plug-in to format or mount a cloud disk type storage volume, optionally, if calling the FlexVolume plug-in through the ECI-Agent component to format the cloud disk type storage volume fails, or the mounting of the cloud disk type storage volume fails, the user can be informed by outputting an alarm prompt message.

[0068] In an optional embodiment, the method further includes: sending an operation request to a cloud disk controller of the serverless container orchestration system, so that the cloud disk controller generates and issues the create cloud disk command.

[0069] In the above optional embodiment, the cloud platform can also send an operation request to the cloud disk controller DiskController of the ASK system. The main function of the cloud disk controller DiskController is to receive and respond to the user's operation request for the persistent storage volume declaration, and then realize the operation of automatically and dynamically creating persistent storage volume resources by generating and issuing a cloud disk creation command.

[0070] In an optional embodiment, the method further includes: when creating container resources through a serverless container orchestration system, creating a storage volume on an elastic block storage device, wherein the type of the storage volume is a container orchestration system storage plug-in type.

[0071] In the above optional embodiment, when creating container resources through the ASK system, it is necessary to create a storage volume in the elastic block storage device EBS, so as to achieve the purpose of automatically creating or deleting container resources based on the elastic block storage device EBS, and because the type of the storage volume is the container orchestration system storage plug-in type, the elastic container instance ECI can interact with the elastic block storage device EBS based on the FlexVolume plug-in.

[0072] Still Figure 4As shown in the figure, the parameter adaptation of the persistent storage volume declaration PVC to the persistent storage volume PV resource of the elastic container instance ECI is implemented through the virtual node Virtual Kubelet in the ASK system, which will not affect the user's habit of using the Kunernetes system at all. Specifically, the virtual node Virtual Kubelet converts the usage of the persistent storage volume declaration PVC of the existing K8S system into the usage of the cloud disk type storage volume supported by the elastic container instance ECI, so that the elastic container instance ECI can interact with the elastic block storage device EBS based on the FlexVolume plug-in.

[0073] It should be noted that in the embodiment of the present application, the life cycle of PVC / PV in the ASK system is not strongly dependent on the life cycle of the container resource Pod in the ASK system. After the ASK system deletes the container resource Pod, you can still choose to retain the PVC. When creating a new container resource Pod, you can continue to use the PVC to achieve data reuse and persistent storage. In addition, when the cloud disk controller DiskController creates a persistent storage volume PV resource, it also creates a storage area in the elastic block storage device EBS, thereby making full use of the high performance and high availability of the block storage in the elastic block storage device EBS.

[0074] Under the above operating environment, this application provides Figure 5 Another method of processing a container group instance is shown. Figure 5 is a flowchart of another method for processing a container group instance according to an embodiment of the present application, such as Figure 5 As shown, the method for processing the container group instance includes:

[0075] Step S502: Generate a control command, wherein the control command is used to call an elastic container instance on a cloud platform to create a container group instance and to create a persistent storage volume resource on an elastic block storage device;

[0076] Step S504: Send a control command to the cloud platform, so that the cloud platform creates the container group instance and the persistent storage volume resource according to the control command.

[0077] In an embodiment of the present application, based on compliance with the K8S system's usage specifications for persistent storage volume declarations PVC, a control command is generated through a serverless container orchestration system, wherein the control command is used to call an elastic container instance on a cloud platform to create a container group instance and to create a persistent storage volume resource on an elastic block storage device; a control command is sent to the cloud platform so that the cloud platform creates the container group instance and the persistent storage volume resource in accordance with the control command.

[0078] Based on the embodiment of the present application, the serverless container orchestration ASK system generates and sends a control command to the cloud platform, and then the cloud platform calls the elastic container instance on the cloud platform according to the control command through the elastic container instance management and control system to create a container group instance and a persistent storage volume PV resource on the elastic block storage device EBS, and uses the persistent storage volume declaration PVC method to persistently store the data generated by the container group instance in the persistent storage volume PV resource, thereby achieving the purpose of persistently storing the data generated by the ECI container group instance in the persistent storage volume PV resource created by the elastic block storage device EBS by the persistent storage volume declaration PVC method, thereby providing persistent storage capabilities for user business data of the cloud platform.

[0079] As a result, the purpose of realizing persistent storage volume declaration based on a serverless container orchestration system is achieved, thereby realizing the technical effect of providing persistent storage capabilities for user business data of the cloud platform, and further solving the technical problem in the prior art that the serverless container orchestration system does not support persistent storage volume declaration and cannot provide persistent storage capabilities for user business data of the cloud platform.

[0080] It should be noted that the execution subject of the embodiment of the present application is a serverless container orchestration system, that is, Figure 4 The ASK system shown.

[0081] In an optional embodiment, the method further includes: performing parameter adaptation processing of the elastic container instance on a virtual node of the serverless container orchestration system to obtain an adaptation result, wherein the adaptation result is used to call the elastic container instance to create a container group instance.

[0082] Optional, still as Figure 4 As shown, in an embodiment of the present application, the parameter adaptation processing of the elastic container instance is performed on the virtual node VirtualKubelet in the ASK system to obtain the adaptation result, and then the elastic container instance on the cloud platform can be called to create a container group instance based on the above adaptation result.

[0083] Through the above optional embodiments, the parameter adaptation of the persistent storage volume declaration PVC to the persistent storage volume PV resource of the elastic container instance ECI is implemented based on the virtual node Virtual Kubelet in the ASK system, which will not affect the user's existing usage habits of the K8S system at all. Specifically, the virtual node Virtual Kubelet converts the persistent storage volume declaration PVC usage supported by the existing K8S system into the cloud disk usage supported by the elastic container instance ECI, and then the elastic container instance ECI can interact with the elastic block storage device EBS based on the FlexVolume plug-in.

[0084] The FlexVolume plug-in is implemented based on the elastic container instance management system and the elastic container instance agent, and the elastic block storage device is used. The virtual node Virtual Kubelet is used as a bridge to connect the ASK system and the elastic container instance ECI. The following innovative designs are also added in the embodiment of the present application:

[0085] In an optional embodiment, performing parameter adaptation processing on the elastic container instance on the virtual node to obtain the adaptation result includes:

[0086] Step S602, using a list mechanism to check the status information of the persistent storage volume declaration on the virtual node;

[0087] Step S604: if it is determined according to the state information that the persistent storage volume declaration is in a pending state, then continue to wait until the persistent storage volume declaration switches from the pending state to the bound state;

[0088] Step S606, after determining that the persistent storage volume declaration enters the binding state, check the persistent storage volume information bound to the persistent storage volume declaration;

[0089] Step S608: After the persistent storage volume declaration and the persistent storage volume bound to the persistent storage volume declaration pass the check, the preset structure is mapped to the open interface parameters of the elastic container instance to obtain the adaptation result.

[0090] In the above optional embodiment, the state information of PVC / PV resources is obtained by adding a list mechanism for PVC / PV resources on the virtual node in the embodiment of the present application. The state information of the persistent storage volume declaration, i.e., the PVC state information, is checked by using the list mechanism; if the state information determines that the PVC is in a pending state, a period of time is waited until the PVC switches from the pending state to the bound state, and after the PVC enters the bound state, the name information of the PV bound to the PVC is checked.

[0091] After obtaining the name information of the PV, query the detailed information of the PV according to the name information of the PV. Specifically, the PV resource supports the storage plug-in of the container orchestration system, such as Figure 4 The FlexVolume plug-in shown, the driver of the FlexVolume plug-in can be a cloud disk or a hard disk.

[0092] As an optional embodiment, after the above-mentioned persistent storage volume declaration and the persistent storage volume bound to the above-mentioned persistent storage volume declaration pass the inspection, the parameters of the elastic container instance are structure-adapted. Specifically, the standard K8S structure can be mapped to the open interface parameters of the elastic container instance (i.e., ECI OpenAPI input parameters) to obtain the above-mentioned adaptation result.

[0093] In an optional embodiment, the above method includes:

[0094] Step S702, receiving an operation request through a cloud disk controller of the serverless container orchestration system;

[0095] Step S704: acquiring a storage type corresponding to the persistent storage volume declaration based on the operation request;
