Hi I wanna solve a problem.
-What I want to achieve
Deploy my app with Fly.io.
-current situation
flyctl auth login →
gem install fly.io-railsupgrade.→
Sending build context to Docker daemon after 39.85kB
I get an error like the one below.

It looks like somehow you managed to name your app -a, and docker isn’t happy with names that start with a dash.
The easiest way to delete that app may be from the dashboard. Type flyctl dashboard to bring up the web page, click on settings and then delete the app from there.
Next delete fly.toml.
At that point you should be able to run fly launch again.
I appreciate your help rubys! I could delete my app then I try to deploy.
Now I’m having another error like the one below
→ v0 failed - Failed due to unhealthy allocations - no stable job version to auto revert to and deploying as v1

-current situation
gem install fly.io-rails →
flyctl launch --name attendancea --region nrt→
flyctl volumes create attendancea --region nrt→
flyctl secrets set DATABASE_URL=sqlite3:///mnt/name/production.sqlite→
flyctl deploy
I try several times but this step did not create a fly.rake file. So when I tried to deploy, I got the above error.

fly.io-rails is experimental. Apparently it is not working for you. So let’s try without it. Remove it from your Gemfile, delete your app, Dockerfile, and fly.toml then run:
fly launch
fly deploy
Note: If you are running flyctl version v0.0.451 or later there will be no fly.rake file generated. If you are running an earlier version of flyctl, please upgrade before running the above commands.
Thank you so much for your help! Much appreciated. I have completed deploy!
