[Feat]: Host Trow Images on a non ghcr Registry

[sharkymcdongles]

Is your feature request related to a problem? Please describe

One of the main use cases for Trow for many people is getting around ghcr ip blacklisting on some providers. Google is quite aggressive with blacklisting certain IPs from pulling images on ghcr. This is especially true on Hetzner Cloud. It'd be very nice if the image wasn't hosted on the provider people are using Trow to get to.

Describe the solution you'd like

Mirror images on dockerhub or quay.

Describe alternatives you've considered

I currently mirror it myself, but it'd be nice if this was part of the general releases.

Hi,
I never heard of a ghcr IP blacklist nor can find any info on that, you are saying this is happening on GCP and Hetzner Cloud ?

On Hetzner cloud the external IPv4 IPs that get assigned randomly are typically blacklisted by ghcr because many of their IPs were maliciously used by botnets in the past. Here is a post describing the same: https://www.reddit.com/r/hetzner/comments/12kg2vt/network_access_to_google_cloud_blocked/ So for me the best workaround has been trow and cilium egress gateway. Basically assign unblocked ip to egress for trow NS then all images can pull fine. Only issue is having to selfhost and push the latest trow to dockerhub myself.
