docker push到本地仓库失败

开启registry的方法：

docker run -d -p : -v /data/registry:/tmp/registry registry

出错内容：

Error: Status  trying to push repository mongodb:
 "<!DOCTYPE HTML PUBLIC \"-//W3C//DTD HTML 3.2 Final//EN\">\n
<title>500 Internal Server Error</title>\n
<h1>Internal Server Error</h1>\n
<p>The server encountered an internal error and was unable to complete your request.  Either the server is overloaded or there is an error in the application.</p>\n"

但是却可以读：

[root@centos-docker ~]# docker search 172.20.1.13:
INDEX     NAME      DESCRIPTION   STARS     OFFICIAL   AUTOMATED

解决办法：

1.selinux模式为permissive模式 setenforce 0
2.容器启动，添加--privileged=true
