Upcoming public networking changes for Container Registry from 15 June 2023

Users that use the public network to access IBM Cloud® Container Registry are advised to use a wildcard domain, such as *.icr.io, in their firewall rules. The use of a wildcard domain accommodates future changes that might issue a redirect for certain requests such as an image layer download for traffic optimization.

The original announcement was published on 15 June 2023.

This advice is a change from existing advice that states that you must allow only the public domain of the Container Registry that you are using.
