Abstract

A cloud server for providing a container-based cloud service, and a method thereof are provided. The cloud server includes a communicator configured to receive a volume mount request, a memory storing one or more instructions, and a processor configured to execute the one or more instructions stored in the memory to, when the processor receives a volume mount request from a first user of a first container among a plurality of containers, identify the first container, check a volume mount right of the first container, and mount a volume that is mountable on the first container.

First claim

What is claimed is:

1. A cloud server for providing a container-based cloud service, the cloud server comprising:
a communicator configured to receive a volume mount request;
a memory storing one or more instructions; and
at least one processor configured to execute the one or more instructions stored in the memory to:
generate a first sub container corresponding to a first container in a same host where the first container is located,
control, when a volume mount request is received from a first user of the first container, the volume mount request to be transferred to the first sub container,
control the first sub container to check a volume mount authority of the first container and request a host operating system (OS) to mount a first volume that is mountable on the first container, and
control the first volume to be mounted on the first sub container.

2. The cloud server of claim 1 , wherein the at least one processor is further configured to execute the one or more instructions to control the volume mount request to be transferred from the first container to the first sub container through an application programming interface (API).

3. The cloud server of claim 1 ,
wherein the first container and the first sub container share a host volume, and
wherein the host volume is correctable by only the first sub container.

4. The cloud server of claim 3 , wherein the at least one processor is further configured to execute the one or more instructions to control the first volume to be mounted to the first container by allowing the first container and the first sub container to share the host volume.

5. The cloud server of claim 1 ,
wherein the communicator is further configured to receive a request for generating a first application from the first user, and
wherein the at least one processor is further configured to execute the one or more instructions to generate the first container and the first sub container corresponding to the first application, in response to the request for generating the first application.

6. The cloud server of claim 5 ,
wherein the first container comprises the first application, and
wherein the first sub container comprises a sidecar of the first application.

7. The cloud server of claim 5 , wherein the at least one processor is further configured to execute the one or more instructions to:
generate the first container and the first sub container in a first name space, and
generate a second container and a second sub container corresponding to a second application in a second name space, in response to a request for generating the second application.

8. The cloud server of claim 1 ,
wherein the first container is assigned a user authority level, and
wherein the first sub container is assigned an administrator authority level.

9. A method of operating a cloud server for providing a container-based cloud service, the method comprising:
generating a first sub container corresponding to a first container in a same host where the first container is located;
receiving a volume mount request from a first user of the first container;
transferring the volume mount request to the first sub container;
checking a volume mount authority of the first container by the first sub container, and requesting a host operating system (OS) to mount a first volume that is mountable on the first container; and
mounting the first volume on the first sub container.

10. The method of claim 9 , wherein the transferring of the volume mount request to the first sub container comprises transferring the volume mount request from the first container to the first sub container through an application programming interface (API).

11. The method of claim 9 ,
wherein the first container and the first sub container share a host volume, and
wherein the host volume is correctable by only the first sub container.

12. The method of claim 11 , wherein the first container is mounted to the first volume by sharing the host volume with the first sub container.

13. The method of claim 9 , further comprising receiving a request for generating a first application from the first user,
wherein the generating of the first sub container corresponding to the first container in the same host where the first container is located comprises generating the first container and the first sub container corresponding to the first application, in response to the request for generating the first application.

14. The method of claim 13 ,
wherein the first container comprises the first application, and
wherein the first sub container comprises a sidecar of the first application.

15. The method of claim 13 ,
wherein the generating of the first container and the first sub container comprises generating the first container and the first sub container in a first name space, and
wherein the method further comprises generating a second container and a second sub container corresponding to a second application in a second name space, in response to a request for generating the second application.

16. The method of claim 9 ,
wherein the first container is assigned a user authority level, and
wherein the first sub container is assigned an administrator authority level.

17. The method of claim 14 , wherein the sidecar of the first application comprises an assistance application including functions in support of the main application.

18. The method of claim 13 , further comprising:
receiving an application deletion request for deleting the first application; and
deleting the first sub container and the first container from the cloud server in response to the request for deleting the first application.

19. A non-transitory computer-readable recording medium storing a program, which when executed by at least one processor, causes the at least one processor to perform the method of claim 9 .
