Is there a way to pull the dagger engine image from a private registry?

[whole siren]

Hello!
I want to pull the image registry.dagger.io/engine:v0.15.0 from my private registry, which is mirroring registry.dagger.io. I found this (old) issue on GitHub with some suggestions: https://github.com/dagger/dagger/issues/5417
I tried export _EXPERIMENTAL_DAGGER_REGISTRY=<myregistry> and export DAGGER_ENGINE_REGISTRY=<myregistry>. But when I run for example dagger init ... it still tries to pull from registry.dagger.io. Is this not supported?

Hello, @whole siren
Have you checked out this section of the docs?
https://docs.dagger.io/configuration/custom-runner#connection-interface
Maybe setting _EXPERIMENTAL_DAGGER_RUNNER_HOST=docker-image://<container image reference> should to the trick 🙂
