在push镜像到本地registry时，出现以下错误：
]# docker push 192.168.163.131:5000/test The push refers to a repository [192.168.163.131:5000/test] 9ec45e5f0334: Retrying in 1 second 33f1a94ed7fc: Retrying in 1 second b27287a6dbce: Retrying in 1 second 47c2386f248c: Retrying in 1 second 2be95f0d8a0c: Retrying in 1 second 2df9b8def18a: Waiting received unexpected HTTP status: 500 Internal Server Error

将selinux禁用
# setenforce 0
# getenforce
Permissive
禁用之后就可以push了
