Description

Technical Field

[0001] The present application relates to the field of cloud technology, and in particular to a container-based service method, device, and computer program product. Background Art

[0002] With the explosive development of Internet applications, traditional virtualization technology has been gradually replaced by container (Docker) technology due to its shortcomings such as slow cold start and high resource usage. Compared with virtual machines, containers have advantages such as short startup time and low performance loss, and play a vital role in the current agile development model.

[0003] Although container images have been greatly reduced in size compared to traditional virtual machines, they are still relatively large for current edge node devices. This results in a small number of container applications that can be deployed simultaneously on edge nodes, and they cannot be fully applied to edge computing scenarios. Summary of the invention

[0004] The purpose of this application is to provide a container-based service method, device and computer program product, which can solve the problem that edge node devices cannot deploy container applications in large quantities.

[0005] In order to achieve the above purpose, the embodiment of the present application is implemented as follows: In a first aspect, a container-based service method is provided, which is applied to an edge node device, wherein the edge node device is deployed with at least one container application and stores a basic container image of the at least one container application, wherein the basic container image is obtained by separating a dependent library from a corresponding container application, and the method comprises: Obtaining a dependency library of a target container application from a cloud device, wherein the cloud device stores a dependency library of at least one container application, and the target container application belongs to the at least one container application; Generate an application image of the target container application based on the locally stored basic container image of the target container application and the acquired dependent library of the target container application; Run the application image of the target container application to provide a service corresponding to the target container application.

[0006] In a second aspect, a container-based service method is provided, which is applied to a cloud device, wherein the cloud device stores a dependency library of at least one container application, and the method includes: In response to a service request of a target container application initiated by a user, obtaining a locally stored dependency library of the target container application, where the target container application belongs to the at least one container application; Sending a dependency library of a target container application to an edge node device, so that the edge node device generates an application image of the target container application based on a locally stored base container image of the target container application and an acquired dependency library of the target container application; wherein the edge node device is deployed with at least one container application and stores a base container image of the at least one container application.

[0007] In a third aspect, an embodiment of the present application provides an electronic device, comprising: a processor; and a memory configured to store computer-executable instructions, wherein the computer-executable instructions, when executed, cause the processor to execute the method described in the first aspect or the second aspect.

[0008] In a fourth aspect, an embodiment of the present application provides a computer program product, which includes a computer-readable storage medium storing a computer program, and the computer program is operable to cause a computer to execute the method described in the first aspect or the second aspect.

[0009] The embodiment of the present application separates the application image of the traditional container application into two parts: the basic container image and the dependent library. The basic container image part is stored in the database of the edge node device. The dependent library part is stored in the database of the cloud device. For the edge node device, the space occupied by the container application is greatly reduced, so high-density container application deployment can be achieved. Correspondingly, the local database of the cloud device records the dependent libraries of all container applications deployed by the edge node device. In related applications, when the user needs to use the service of the target container application, a service request for the target container application can be sent to the cloud device. Afterwards, the cloud device responds to the user's service request, obtains the dependent library of the target container application from the local database, and sends the dependent library of the target container application to the edge node device. Correspondingly, the edge node device further restores the application image of the traditional target container application based on the basic container image of the local target container application and the received basic container image of the target container application to run and provide services.

[0018] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this specification, not all of the embodiments. Based on the embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this specification.

[0019] This application proposes a container-based service solution, which aims to separate the application image of the traditional container application into two parts: the basic container image and the dependent library. The basic container image part is stored in the database of the edge node device. The dependent library part is stored in the database of the cloud device. For the edge node device, the space occupied by the container application is greatly reduced, so high-density container application deployment can be achieved. Correspondingly, the local database of the cloud device records the dependent libraries of all container applications deployed by the edge node device. In related applications, refer to Figure 1 As shown, when the user needs to use the service of the target container application, he can send a service request for the target container application to the cloud device. After that, the cloud device responds to the user's service request, obtains the dependency library of the target container application from the local database, and sends the dependency library of the target container application to the edge node device. Correspondingly, the edge node device further restores the application image of the traditional target container application based on the basic container image of the local target container application and the received basic container image of the target container application to run the target container application.

[0020] based on Figure 1 The container application operation mode shown. On the one hand, the present application proposes a container-based service method. Figure 1 This is a flow chart of the service method applied to the edge node device side, including the following steps: S102: Obtain a dependency library of a target container application from a cloud device. The cloud device stores a dependency library of at least one container application, and the target container application belongs to at least one container application.

[0021] Dependent libraries are software libraries or frameworks required by container applications at runtime or compile time. They are used to provide the functions and services required by the application so that the container application can run normally.

[0022] In this embodiment, the dependent library of the target container application is determined based on the behavior record of the application image of the target container application when testing the application image of the target container application. The behavior record may include, but is not limited to, file call records and / or system call records. Correspondingly, the base container image of the target container application is obtained by separating the dependent library from the corresponding target container application.

[0023] That is, the basic container image is equivalent to a lightweight image after removing the dependent libraries.

[0024] S104: Generate an application image of the target container application based on the locally stored basic container image of the target container application and the acquired dependency library of the target container application.

[0025] S106: Run the application image of the target container application to provide a service corresponding to the target container application.

[0026] It should be noted that the target container application can provide more than one service, and this embodiment does not specifically limit this.

[0027] Correspondingly, Figure 2 This is a flow chart of the service method applied to the cloud device side, which specifically includes the following steps: S202, in response to a service request of a target container application initiated by a user, obtaining a locally stored dependency library of the target container application, where the target container application belongs to at least one container application.

[0028] Specifically, before obtaining the locally stored dependency library of the target container application, the cloud device may test the application image of the target container application to determine the dependency library of the target container application based on the behavior record of the application image of the target container application during the test. The behavior record may include, but is not limited to, file call records and / or system call records.

[0029] As an example introduction, Figure 4This is a flowchart for testing the application image of the container application. First, a monitoring program for monitoring the container behavior is implanted in the application image of the traditional container application. Next. The application image of the container application is started to test according to the test rules specified by the user. During the test, the container behavior collected by the monitoring program is added to the behavior database for storage. Finally, after the test is completed, all container behaviors are retrieved from the behavior database for analysis to determine the corresponding dependent libraries. Among them, if multiple dependent libraries are determined, they are represented in the form of a dependent library list.

[0031] In addition, corresponding to Figure 2 Another embodiment of this embodiment further provides an edge node device, which is deployed with at least one container application and stores a basic container image of the at least one container application, wherein the basic container image is obtained by separating the dependent library from the corresponding container application, and the edge node device.

[0033] The running module 530 is used to run the application image of the target container application to provide the service corresponding to the target container application.

[0034] Optionally, the dependent library of the target container application is determined based on a behavior record of the application image of the target container application when the application image of the target container application is tested. The behavior record includes a file call record and / or a system call record.

[0036] In addition, corresponding to Figure 3 Another embodiment of this embodiment further provides a cloud device, which stores at least one dependency library of a container application.

[0037] The sending module 620 is used to send the dependency library of the target container application to the edge node device, so that the edge node device generates an application image of the target container application based on the locally stored basic container image of the target container application and the acquired dependency library of the target container application; wherein the edge node device is deployed with at least one container application and stores the basic container image of the at least one container application.

[0038] Optionally, before obtaining the locally stored dependency library of the target container application, the response module 610 is further used to: test the application image of the target container application to determine the dependency library of the target container application based on the behavior record of the application image of the target container application during the test.
