在docker python中运行copy命令无法处理星号

如何解决在docker python中运行copy命令无法处理星号

我正在尝试运行docker容器以将文件从卷复制到本地文件夹：

import docker
client = docker.from_env()
stdout = client.containers.run(
    "alpine",mounts=[
        docker.types.Mount(
            "/data_to",os.path.abspath("./data_localhost"),'bind')
    ],volumes={
        volume_name: {'bind': '/data_from','mode': 'rw'}
    },working_dir='/data_from',command=["cp","/data_from/*","/data_to/"]
    # command=["touch","/data_to/a"]
    # command=["ls","/data_from/"]
)
logging.info(stdout.decode("utf-8"))

但是我明白了

docker.errors.ContainerError: Command '['cp','/data_from/*','/data_to/']' in image 'alpine' returned non-zero exit status 1: b"cp: can't stat '/data_from/*': No such file or directory\n"

似乎无法正确处理星号。为什么会这样？

我可以正确放置/data_from/的内容，也可以从容器内将数据写入/data_to/。
