Specifically, in response to a startup operation of a target container, the host node can generate a corresponding container startup event, and after receiving the container startup event, the mirror volume management module analyzes the container startup event, determines a target container to be started, and a target read-write volume corresponding to the target container.
Step 302, an input/output request is sent to a container image file system of the kernel space through a target container of the user space.
Specifically, under the condition that the target container is started, the target container needs to load a corresponding container mirror image, and the target container sends an input and output request to a container mirror image file system to realize reading and writing of the container mirror image.
In step 303, an input/output request is received through the container mirror file system and forwarded to the FUSE kernel module in kernel space.
The format of the container image file system may be a FUSE format.

And 305, acquiring target data corresponding to the input/output request through a container mirror image driving module. The target data may be data in the target read-write volume or container mirror data in the target base volume.
Optionally, when the host node is started, the base volume corresponding to the host node may be determined by mounting from the distributed storage system, and the base volume is mounted to the host node, and if the base volume does not exist, the base volume corresponding to the host node is created according to the cloud primary cluster information or the container cloud platform information corresponding to the host node. And, a buffer area can be applied for the host node and the FUSE kernel module in the host node can be loaded.
