silenceper / docker-tar-push Goto Github PK

command：./docker-tar-push ./nginx-alpine.tar --registry=https://192.168.66.232/line19 --log-level=4 --skip-ssl-verify=true --username=admin --password=holly***

这里应该修改为：return false, nil，才可以使得不存在时push吧。

官方API介绍如下：
Existing Layers

The existence of a layer can be checked via a HEAD request to the blob store API. The request should be formatted as follows:

HEAD /v2/<name>/blobs/<digest>

If the layer with the digest specified in digest is available, a 200 OK response will be received, with no actual body content (this is according to http specification). The response will look as follows:

200 OK
Content-Length:
Docker-Content-Digest:

When this response is received, the client can assume that the layer is already available in the registry under the given name and should take no further action to upload the layer. Note that the binary digests may differ for the existing registry layer, but the digests will be guaranteed to match.

另外，ParseImageAndTag函数中，repo有可能在最前面包含ip:port/xxx/xx:1.0.0 这样。
