Container operation method and device, equipment and storage medium

Abstract

The embodiment of the invention discloses a container operation method and device, equipment and a storage medium, and belongs to the technical field of computers. The method comprises the following steps: starting a file cache container, wherein the file cache container is started by a first container; in response to a nested container construction instruction of the first container, storing a target mirror image file to the file cache container, the nested container construction instruction being used for instructing to construct a second container in the first container, and the target mirror image file being used for supporting operation of the second container; and in response to a running instruction of the second container, obtaining the target mirror image file in the file cache container, and running the second container based on the target mirror image file. In the embodiment of the invention, the target mirror image file can be directly obtained in the file cache container, and then the second container is operated based on the target mirror image file, so that the operation failure of the second container caused by the fact that the target mirror image file cannot be obtained is avoided, and the container operation success rate is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and in particular, to a method, device, device, and storage medium for running a container. Background technique [0002] Currently, developers can package applications and dependencies into portable containers through the open source application container engine (docker), allowing them to run in any environment. Nested container (dockerindocker) refers to the technology that developers need to build images or run other containers in a container during the development process. [0003] When the container is running, it needs to run based on the image file. In the nested container running scenario, the container shares the docker daemon on the host. Due to the isolation of the container, it can only obtain the image file of the host where the docker daemon is located. [0004] However, during the running of the nested container, it is necessary to obtain some image ...

Problems solved by technology

In the nested container running scenario, the container shares the docker daemon on the host. Due to the isolation of the container, it can only obtain the image file of the host where the docker daemon resides.

[0004] However, during the running of the nested container, it is necessary to obtain some image files in the nested container, but due to permission issues, the image file in the nested container cannot be successfully obtained, which leads to the failure of the nested container to run
