Harbor: Image Replication for Quay.io

[niiku]

We would like to use Harbor as "gateway" registry for our kubernetes environments so that every image is security scanned. We would like to provide our developer the possibility to import external images. Currently, the image replication from Docker Hub works really well. But sadly, the image replication from quay.io doesn't work. Every transfer tasks of a quay.io image ends like this:

2019-07-25T20:44:11Z [INFO] [/replication/transfer/image/transfer.go:95]: client for source registry [type: docker-registry, URL: https://quay.io, insecure: true] created

Quay.io was created as Endpoint under "Registries" with:
Provider: docker-registry
ExternalUrl: https://quay.io

I tested several different images from quay.io but I could not replicate one of them. So I guess it's not supported yet.

As Quay.io is one of the largest registries it would be very useful if the replication would be supported too.

@niiku Yep，harbor has not provided the implementation of quay.io adapter, as you say, Quay.io is one of the largest registries, so i will do some work for quay.io adapter, it will be supported later.

@chlins Thank you for your answer. Let me know if I can help you.

@niiku replication to / from Quay is now supported in latest release : https://github.com/goharbor/harbor/releases/tag/v1.10.0. Give it a go and let us know what you think. Thanks!

@xaleeks Please excuse the late answer. When I tested the feature in January it still didn't work for me. But I just installed the latest version and it works perfectly fine! Many thanks for the awesome work!
