In Docker, the permission problem of the mounting directory can usually be solved by the following method: adding permission-related options when using the -v parameter to specify the mounting directory. You can specify the permissions of the mounted directory by adding: ro or :rw after the mounted directory, indicating read-only and read-write permissions respectively. For example: dockerrun-v/host/path:/container/path:roimage_name Define the USER directive in the Dockerfile to specify the user running in the container to ensure that operations inside the container comply with permission requirements. For example: FROMimage_name#CreateanewuserRUNuseradd-ms/bin/
