Question

我一直在尝试在主机和docker容器之间共享数据。我正在使用此命令挂载数据卷：

sudo docker run -it -v /home/peeyush/Docker/docker/:/opt/test/:rw ubuntu /bin/bash

现在，当我运行docker并尝试访问/ opt / test /时，它表示我没有权限。但我已经指定了读写权限，我是root用户。这是输出：

root@d61b3bfe0aab:/# ls /opt/test/
ls: cannot open directory /opt/test/: Permission denied

知道我在这里做错了什么吗？

更新：这是ls -al / home / peeyush / Docker / docker的输出：

[peeyush@localhost docker]$ ls -al /home/peeyush/Docker/docker/

感谢。

Answer 1

在SELinux上使用发行版？您可以尝试将其转换为被动（setenforce 0）或在-v命令的末尾尝试：Z /：z，如（/ home / peeyush / Docker / docker：/ opt / test：Z）

Answer 2

有兴趣看看它是否在目录路径上没有尾随'/'的情况下工作，因为我从未使用它们，也从未遇到过这个问题。

sudo docker run -it -v / home / peeyush / Docker / docker：/ opt / test ubuntu / bin / bash

无法访问共享数据卷
