Stalling on Saving registry.fly.io cache

Sorry to hear that you’re still having trouble, … People have generally been nudging users away from the buildpacks of late:

@Brad

It looks like your project uses a Heroku buildpack, which tries to do everything for everybody making it harder to debug. If you add a Dockerfile you’ll see exactly what is running on your machine, which makes troubleshooting easier.

Also…

Buildpacks are slow and we kind of regret enabling them. If you can write a Dockerfile, it’s a much better experience.

Consequently, if you are using a buildpack, then perhaps the next troubleshooting step is to switch to an explicit Dockerfile.

@rubys has an npx invocation that generates a credible starter one, if I understand correctly. (I don’t use Node myself, though.)

If you search the forum archives, you should see it come up several times—and then you can gauge whether it fits your particular context, etc.

Hope this helps a little!
