sealer 只需要纯净版本的服务器就可以了,会自动安装docker 或者 container ,不需要手动安装容器运行时

@zsyaoo 这个你确定是自动安装docker？，我在ubuntu18.04上运行sealer run一直报错提示docker没有运行，重装了系统好几次，结果都是一样，之后我手动安装docker之后sealer run就成功运行了 没有手动安装docker会报这个错误，貌似docker daemon没有启动起来，不知道sealer这边为啥启动docker失败了,手动安装的都是正常启动了

Usage:
  sealer run [flags]

Examples:

create cluster to your bare metal server, appoint the iplist:
        sealer run kubernetes:v1.19.8 --masters 192.168.0.2,192.168.0.3,192.168.0.4 \
                --nodes 192.168.0.5,192.168.0.6,192.168.0.7 --passwd xxx

docker 日志报错,看是找不到iptables路径，但是我看ubuntu18.04是在/sbin/iptables路径

@Hello-Linux

There is no doubt that docker will be installed automatically by sealer. While for the below message:

+ docker load -q -i /var/lib/sealer/data/my-cluster/rootfs/images/registry.tar
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

I think it is because that docker daemon has failed to startup. In this case, maybe showing more logs about dockerd could be more helpful. If the environment is still there, could you help to show the log of dockerd, maybe the file /var/log/docker.log ?

@allencloud ### Ubuntu18.04 iptables path is /sbin/iptables,not in /usr/sbin/iptables,sealer should use /sbin/iptables. when I create a link for iptables with run command "ln -sf /sbin/iptables /usr/sbin/iptables", then the sealer run is success!!!!!!!!! so the searler should auto find the iptables path which iptables

sealer初始化会调用clean.sh，rm了

遇到了相同的问题，在阿里云服务器中，系统Ubuntu 18.0.4，希望安装一个单节点的k8s集群（希望在本服务器安装，因此先后试过服务器ip和本地ip 127.0.0.1）。

OS: ubuntu 18.04 linux kernel: 4.15.0-192-generic sealer version: {"gitVersion":"v0.8.6","gitCommit":"884513e","buildDate":"2022-07-12 02:58:54","goVersion":"go1.16.15","compiler":"gc","platform":"linux/amd64"}

运行sealer run -m 127.0.0.1 -p xxx之后出现以下提示：

以服务器公网ip作为master ip来安装时(卸载了自己安装的docker)，出现以下提示：

sealer不知道现在支不支持Ubuntu，执行以下重试即可： sed -i '/iptables/d' /lib/systemd/system/docker.service echo "ExecStartPost=/usr/sbin/iptables -P FORWARD ACCEPT" >> /lib/systemd/system/docker.service systemctl daemon-reload && systemctl restart docker
