How can I configure another process in production along with rails server

1

Hi All,
Happy New Year! :tada:

I have a rails application deployed in fly.io. The fly.toml was generated automatically by fly CLI.

I have searched the fly documentation on how to launch another process for running sidekiq and found this. I don’t see any default process like “web” defined in my fly.toml and the fly.toml.

Here are fly.toml contents

processes = []

[build]
  [build.args]
    BUILD_COMMAND = "bin/rails fly:build"
    SERVER_COMMAND = "bin/rails fly:server"

[deploy]
  release_command = "bin/rails fly:release"

[env]
  PORT = "8080"

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["app"]
  protocol = "tcp"
  script_checks = []

And here is Procfile

backend: bin/rails server -p 3000
frontend: bin/vite dev
worker: bundle exec sidekiq

I have modified fly.toml with multiple process, it is throwing this error message,

web = "bin/rails fly:server"
worker = "bundle exec sidekiq"

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["web"]


Error Your fly.toml referenced an attribute 'web' but it is unknown. Double check the accepted attributes in fly.toml https://fly.io/docs/reference/configuration

Bit confused about coping with the commands from Procfile to fly.toml. How can I run both rails server and sidekiq worker?

I previously had asked a similar question here, I am a bit concerned about adding below code, as if one process fails entire app will fail to run

fork { sh 'bundle exec sidekiq' }

Could someone help me,

Thanks in advance. :pray:

if your app is rather small and you are using Sidekiq 7, you could try using Sidekiq Capsule.

about your error, I believe the problem is in the docs. the processes declaration should be indented under processes, like this

[processes]
  web = "bin/rails fly:server"
  worker = "bundle exec sidekiq"

at least it is like that in this example too so it might be it
