Docker 如何装载卷vscode开发容器

当我在VS代码中使用“Docker Docker”映像并尝试使用卷运行Docker映像时，显示以下错误：

docker: Error response from daemon: invalid mode: / workspace.

devcontainer.json：

// Use this environment variable if you need to bind mount your local source code into a new container.
"remoteEnv": {
    "LOCAL_WORKSPACE_FOLDER": "${localWorkspaceFolder}"
},

命令：

docker run -it --rm -v ${LOCAL_WORKSPACE_FOLDER}:/workspace debian bash
