May 16 02:03:58 localhost python: SELinux is preventing /bin/registry from add_name access on the directory docker.

*****  Plugin catchall_labels (83.8 confidence) suggests   *******************

If you want to allow registry to have add_name access on the docker directory
Then you need to change the label on docker
Do
# semanage fcontext -a -t FILE_TYPE 'docker'
where FILE_TYPE is one of the following: cgroup_t, container_var_lib_t, nfs_t, svirt_home_t, svirt_sandbox_file_t, virt_home_t. 
Then execute: 
restorecon -v 'docker'

将selinux禁用

# setenforce 0
# getenforce 
Permissive

禁用之后就可以push了
