Yeah, you need to either create a database or run migrations. This is a good starting place: Running Tasks & Consoles · Fly Docs

3

Most likely you are using sqlite3 and your migrations are being run during the release step instead of as a prerequisite of the server step. Modify lib/tasks/fly.rake to move the db:migrate dependency.

Thank you for this. I ran the db migrate for fly and it is now working

Thanks for the suggestion

Hello, i have the same problem and i don’t know how to solve, can you please explain how to modify the fly.rake file?

Thanks!

Before:

task :release => 'db:migrate'
task :server => :swapfile do

After:

task :release
task :server => [:swapfile, 'db:migrate'] do

Hello thank you very much for your reply, but i think now that my problem is not related.

I need to write temp files with File.write(“tmp/uploads/” + @file_name, @codice)

but i think there are problems with file permission… can you help?

Your .dockerignore file includes tmp. Easiest fix is probably to create tmp/uploads in your Dockerfile:

Change:

RUN mkdir -p tmp/pids

To:

RUN mkdir -p tmp/pids tmp/uploads

Hello again, thank you very much, now it works :slight_smile:
