是否可以嵌套Docker/Podman容器

我运行Fedora 35，需要在Ubuntu的Docker运行一个应用程序。我能够通过Podman

podman pull ubuntu:20.04

和Setup Do Docker在那里获得Ubuntu，但无法运行它，因为我可能没有正确地进入Podman。我使用过：

podman run -it ubuntu:20.04

我运行的地方：

su -
apt update; apt upgrade
apt install inetutils-ping nano sudo npm
apt install apt-transport-https ca-certificates curl gnupg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \                                                                                            $(lsb_release -cs) stable" |sudo tee /etc/apt/sources.list.d/docker.list > /dev/null                                                                                                                                  apt update
apt install docker-ce docker-ce-cli containerd.io

在容器中不可能通过 systectl 启动Docker，并且 dockerd 命令给出了许多错误，主要是它无法访问覆盖层，并且可能网络（iptables）

ERRO [2022-05-07T23：14：18.803335993+02：00]无法安装覆盖：操作不允许存储-DRIVER = OVERLAY2 erro [2022-05-07T23：14：18.803397023+02：00] exec：“ fuse-overlayfs”：在$ path storage-driver中找不到可执行文件 ERRO [2022-05-07T23：14：18.803500924+02：00] AUFS WDA在 /proc /proc /filesystems storemate-drover = aufs中找不到 ERRO [2022-05-07T23：14：18.803887844+02：00]无法安装覆盖层：操作不允许存储-DRIVER =

完全可以运行和应用程序可以使用Service以开放端口，以开放端口Podman有2层嵌套容器？

I run Fedora 35, and need to run an app in docker in ubuntu.
I was able to get and run ubuntu via podman

podman pull ubuntu:20.04

and setup do docker there, but can't make it run as I probably didn't enter podman properly probably. I used:

podman run -it ubuntu:20.04

where I ran:

su -
apt update; apt upgrade
apt install inetutils-ping nano sudo npm
apt install apt-transport-https ca-certificates curl gnupg
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg
echo "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \                                                                                            $(lsb_release -cs) stable" |sudo tee /etc/apt/sources.list.d/docker.list > /dev/null                                                                                                                                  apt update
apt install docker-ce docker-ce-cli containerd.io

to start docker via systectl is not possible in the container, and dockerd command gives many error, mostly that it can't access overlay, and probably network (iptables)

ERRO[2022-05-07T23:14:18.803335993+02:00] failed to mount overlay: operation not permitted storage-driver=overlay2
ERRO[2022-05-07T23:14:18.803397023+02:00] exec: "fuse-overlayfs": executable file not found in $PATH storage-driver=fuse-overlayfs
ERRO[2022-05-07T23:14:18.803500924+02:00] AUFS wdas not found in /proc/filesystems storage-driver=aufs
ERRO[2022-05-07T23:14:18.803887884+02:00] failed to mount overlay: operation not permitted storage-driver=overlay

Is it possible at all to run and app with service to have open port to outside of docker, and podman as there are 2 layers of nested containers?
