1、创建软链接把podman命名为docker

sudo ln -sf /usr/bin/podman /usr/bin/docker

2、设置docker容器开机启动

启用并启动 podman-restart    

sudo systemctl enable --now podman-restart.service

sudo systemctl status podman-restart.service

docker update --restart=always sw_redis

docker update --restart=always sw_nginx

3、确保restart=always生效

确保容器已设置重启策略  

podman inspect sw_nginx --format '{{.HostConfig.RestartPolicy.Name}}'

podman inspect sw_redis --format '{{.HostConfig.RestartPolicy.Name}}'
