Issues deploying first app (stuck on flyctl launch)

1

Hi there,

I follow the steps in the docs to deploy my first app.
It is a go app based on this doc.
When I run:

➜ flyctl launch
An existing fly.toml file was found for app drio-fly-test
App is not running, deploy...

flyctl gets stucked without making any progress. I don’t see any traffic on my nic. Not sure what may be happening.

I am using:

➜ flyctl version
flyctl v0.0.450 darwin/arm64 Commit: 51325e4a BuildDate: 2023-01-13T21:54:03Z

After a few minutes the process continues successfully (see below).
I think the issue was that docker could not pull the gcr.io/paketo-buildpacks/go:latest and the timeout was set pretty high. I think I had to wait for 5 minutes or so.

That long pause is when buildpacks is resolving all the steps for each builder. This can take some serious time unfortunately. We suggest folks use a Dockerfile to get faster builds and smaller images.
