The problem still exists in version 23.0.7

Re: ProGet Docker Connector to gcr.io not working

I met the same problem. After analysed the captured traffic, I found that ProGet encoded the URI incorrectly.

The colon (:) does not need to be encoded in URI (ref https://stackoverflow.com/questions/2053132/is-a-colon-safe-for-friendly-url-use).

GCR needs the original colon rather than %3A, but ProGet encoded it. So we got 404 response from GCR.

Example:

This is a good request:
https://gcr.io/v2/kaniko-project/executor/manifests/sha256:034f15e6fe235490e64a4173d02d0a41f61382450c314fffed9b8ca96dff66b2

But ProGet encoded the colon:
https://gcr.io/v2/kaniko-project/executor/manifests/sha256%3A034f15e6fe235490e64a4173d02d0a41f61382450c314fffed9b8ca96dff66b2
