容器服务器启动异常，提示

containerd.service: main process exited, code=exited, status=2/INVALIDARGUMENT

处理操作：

# systemctl status containerd

# systemctl stop containerd

# cd /var/lib/containerd

# rm -rf * 

# systemctl restart containerd && systemctl enable containerd 

之后重启docker.socket 和docker.service服务均正常

# systemctl restart docker.socket && systemctl enable docker.socket

# systemctl restart docker.service && systemctl enable docker.service
