The invention relates to a file system resource isolation method for a Docker container. The method includes: allocating host file system resources according to the access request of the container anddetermining a lock resource corresponding to the access request, the file system resource isolation method at least comprises the following steps: dividing a lock resource into a first lock capable of being refined and a second lock incapable of being refined based on the granularity of the lock resource, and creating a plurality of new containers in a manner of configuring refined copies of thefirst lock to form independent locks; allocating the host file system resources according to the file resource request parameters required by the new containers, and dividing the plurality of new containers into a first marking container and a second marking container based on the allocation result; and controlling the execution of the file system operation according to the use amount of the filesystem resources allocated to the first marking container or the second marking container under the condition that the lock competition exists or the file system resources need to be used when the first marking container or the second marking container executes the file system operation.
