创建一个容器

[root@duanruhui ~]# podman run -d --name web httpd
917472eaac249e5b95db9a1ddafddbe5d58a30a34adef9c0cc69eef3d3d9d1c1
[root@duanruhui ~]# podman ps

生成service文件

[root@duanruhui ~]# cd /etc/systemd/system
[root@duanruhui system]# podman generate systemd --new --files --name web

[root@duanruhui system]# cat container-web.service

删除刚才的容器

[root@duanruhui system]# podman rm -f web

设置开机自启

[root@duanruhui system]# systemctl enable --now container-web.service 
Created symlink /etc/systemd/system/multi-user.target.wants/container-web.service → /etc/systemd/system/container-web.service.
Created symlink /etc/systemd/system/default.target.wants/container-web.service → /etc/systemd/system/container-web.service.

检验

[root@duanruhui system]# podman ps -a
CONTAINER ID  IMAGE                           COMMAND           CREATED             STATUS                 PORTS       NAMES
6db8b7c0183f  docker.io/library/httpd:latest  httpd-foreground  About a minute ago  Up About a minute ago              web

可以发现，之前已经删除的容器已经恢复了
