Error response from daemon: Unknown runtime specified docker-runc
,,报错①解决方法:,命令:,重新启动docker,,报错②Error response from daemon: error creating overlay mount to /var/lib/docker/overlay2/09f8444f734ca18130ac4e2dafdcd3a19dd2986c9474bd0a50c87c0af559a831/merged: invalid argument
,,报错②解决方法:,推荐修改CentOS下的/etc/selinux/config 将SELINUX=disabled 改成 SELINUX=permissive,或者修改docker关闭selinux,,,,至此低版本Docker升级高版本Docker完美结束~,
