Support for Docker Hardened Images / other registries?

Hi there,

Docker recently made their Docker Hardened Images free for use. This is great, because it allows many people to benefit from greater security in their applications.

Unfortunately, they’re gated behind a new registry they set up that’s separate from docker hub, meaning they cannot be pulled by Render, which only supports a few preconfigured registries.

Is there any plan to add support for custom docker registries? Or docker’s hardened images?

We’re currently evaluating where we’re going to deploy our HIPAA app, with the main contenders being Railway and Render, and this is a bummer / a point in favor of Railway.

Thank you!
