#接下来启动containerd
root@ubuntu:~# systemctl restart containerd.service
root@ubuntu:~# systemctl enable containerd.service
#接下来就开始配置runc
runc
#下载 下来直接就是命令拷贝加权限即可
[centos@worker0 ~]$ wget https://github.com/opencontainers/runc/releases/download/v1.1.4/runc.amd64
#拷贝
root@ubuntu:~# cp runc.amd64 /usr/bin/runc
#加执行权限
root@ubuntu:~# chmod a+x /usr/bin/runc
#拉取镜像
