Description Oleg Bulatov 2019-12-16 23:41:46 UTC
Description of problem:

The image registry operator, when S3 regionEndpoint is specified, tries to use virtual hosted bucket addressing like http://<bucketname>.<regionEndpoint>/<key>. This is not desired behaviour for S3-compatible storages like Minio.

Version-Release number of selected component (if applicable):


How reproducible:

Steps to Reproduce:
1. install an OpenShift cluster and minio storage
2. change the config.imageregistry to use this storage, set the proper regionEndpoint

Actual results:

The operator includes the bucket name into the domain name.

Expected results:

The operator uses path-style addressing like http://<regionEndpoint>/<bucket>/<key>.

But if use http://<bucketname>.<regionEndpoint>/<key>,UnmarshalError appears, so report a bug as below: https://bugzilla.redhat.com/show_bug.cgi?id=1797512
