### 
1. 推送的时候 出现了不明的mount日志
2.  最后500超时的情况

2. 解决办法

## 将 harbor的地址添加到 insecure-registries 中
[root@slave-20-30 ~]#cat /etc/docker/daemon.json 
{
  "insecure-registries": ["reg.ming.cn"],
  "hosts": ["unix:///var/run/docker.sock"],
  "storage-driver": "devicemapper",
  "storage-opts": [
     "dm.basesize=10G",
     "dm.thinpooldev=/dev/mapper/docker-thinpool",
     "dm.use_deferred_removal=true",
     "dm.use_deferred_deletion=true"
   ],
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "20m",
    "max-file": "10"
  },
 "live-restore": false
}

## 重启docker
