Podman 无法将本地文件挂载到容器中
Podman unable to mount local file into container
我打算从 Docker 搬到 Podman。
我经常使用 docker-compose,所以我也打算切换到 podman-compose。
但是我被困在最简单的 podman 示例中,我似乎无法将卷挂载到我的容器上?显然我做错了什么,但我不知道它是什么。
我的源文件肯定存在于我的(硬件)主机上(所以不在 podman 机器上)。但我一直收到错误 'no such file or directory'.
有趣的是,如果我在 podman 机器上本地手动创建相同的文件(podman 机器 ssh --> touch /tmp/test.txt),它工作得很好。
问题是;
- 我是否应该(手动?)将我所有的本地文件挂载到 Fedora VM(podman 机器)上,以便反过来可以在我的实际容器中使用这个 Fedora 挂载?如果是这样,我该怎么做?
- 下面的
podman run
cmd 应该可以工作,还有其他地方我做错了吗?
$ ls -al /tmp/test.txt
-rw-r--r-- 1 <username> <group> 10 Dec 8 13:33 /tmp/test.txt
$ podman run -it -v /tmp/test.txt:/tmp/test.txt docker.io/library/busybox
Error: statfs /tmp/test.txt: no such file or directory
$ podman run -it -v /tmp/test.txt:/tmp/test.txt:Z docker.io/library/busybox
Error: statfs /tmp/test.txt: no such file or directory

正如@ErikSjölund 所提到的,https://github.com/containers/podman 上有一个积极的治疗。显然 Centos(Podman Machine)不(还)支持在机器上创建不同类型的卷。
并不是 Podman 缺少此功能,它正在等待 CentOS 也支持此功能。
但是,如果您想将本地目录挂载到计算机上,我建议您查看 https://github.com/containers/podman/issues/8016#issuecomment-995242552。它描述了如何在 CoreOS 上进行只读挂载(或破坏与本地版本的兼容性)。
