helloruby application doesn't deploy

Questions / Help Build debugging

Hi all, I am a newbie to fly.io and am following the helloruby walkthrough. The application runs locally with rackup, but flyctl launch fails with Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v1. When I look at the logs in the dashboard, I see two lines with errors:

bundler: failed to load command: rackup (/layers/heroku_ruby/gems/vendor/bundle/ruby/3.0.0/bin/rackup)
/workspace/config.ru:3:in `block in <main>': undefined local variable or method `flyctl' for #<Rack::Builder:0x0000563ed8e9af30 @freeze_app=false, @warmup=nil, @run=nil, @map=nil, @use=[]> (NameError)

Would anyone have any suggestions for getting the ruby example app working? Thanks!

As odd as it sounds, try again?

I just ran through the steps, and they worked for me:

Thanks! I tried again, but unfortunately had the same result. However, I did notice that you did not add a Postgresql database (whereas I did originally), so I also tried re-rerunning everything from scratch without setting up a database, and that did work. So, it seems that adding a database was where I went wrong.
