[planktonzp]

when i create a local docker registry with ceph swift storage ,i find that the contianer is working but i cannot push any images to the registry,and when i check the logs of registry contauner and ceph rgw, i find lots of message like that 2017-08-10 00:04:30.744809 7f0c037fe700 1 ====== starting new request req=0x7f0c037f8710 ===== 2017-08-10 00:04:30.748852 7f0c037fe700 1 ====== req done req=0x7f0c037f8710 op status=0 http_status=200 ====== 2017-08-10 00:04:30.748922 7f0c037fe700 1 civetweb: 0x7f0bd80008c0: 172.16.3.92 - - [10/Aug/2017:00:04:30 +0800] "GET /swift/v1/docker_registry HTTP/1.1" 200 0 - distribution/v2.6.2 2017-08-10 00:04:30.749833 7f0c037fe700 1 ====== starting new request req=0x7f0c037f8710 ===== 2017-08-10 00:04:30.751815 7f0c037fe700 1 ====== req done req=0x7f0c037f8710 op status=0 http_status=404 ====== 2017-08-10 00:04:30.751869 7f0c037fe700 1 civetweb: 0x7f0bd80008c0: 172.16.3.92 - - [10/Aug/2017:00:04:30 +0800] "HEAD /swift/v1/docker_registry/files HTTP/1.1" 404 0 - distribution/v2.6.2
