我试图在 CentOS 8 服务器上以非 root 用户身份启动 busybox 容器，但它给出了以下消息。

以非 root 用户身份启动容器的正确方法是什么？

  podman run -it --name busy  docker.io/library/busybox sh
Trying to pull docker.io/library/busybox...Getting image source signatures
Copying blob bdbbaa22dec6 done
Copying config 6d5fcfe5ff done

是的，您运行的命令是正确的。在我的 Fedora 31 系统上它工作得很好。

[testuser@fedora31 ~]$ podman run -it --name busy docker.io/library/busybox sh

/ # exit
[testuser@fedora31 ~]$ podman --version
podman version 1.8.0
[testuser@fedora31 ~]$

该标志--rm通常也很有用。

您得到的错误似乎与 UID 映射有关。

以下是有关运行“无根”podman 的一些信息：

还有什么可能很有趣：
