The container registry is being deprecated in favor of Artifact Registry (see
https://cloud.google.com/artifact-registry/docs/transition/transition-from-gcr). AR will provide
gcr.io support so it can redirect requests from
gcr.io hosts to AR. Hopefully this means existing scripts and workflows won't need to be changed.
AFAICT, IREE uses GCR for storing docker images. These are manually pushed and read by by human users and github workflows. I don't have visibility into how often the registry is written to.
For the migration, the GCR artifacts will be copied over to an AR equivalent. Once the copy is complete, I can flip the switch to turn on the redirect. We might lose anything that's copied uploaded after the copy starts but before the redirect is turned on.
Please let me know if there are any questions or concerns about this migration,
Nancy
