Rails and Resque setup

Questions / Help
1

Hi, I recently deployed an app and a redis client. My app uses resque, and I can’t figure out how to get it to all work together to accept a background job. Can anyone walk me through this?

When I updated my fly.toml file as suggested in this guide, my deploys failed. For completeness, here is the file:

# fly.toml file generated for arelplane on 2022-10-28T18:42:53-04:00

app = "arelplane"
kill_signal = "SIGINT"
kill_timeout = 5
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"

[experimental]
  allowed_public_ports = []
  auto_rollback = true

[processes]
  web = "bin/rails fly:server"
  worker = "bundle exec rake resque:work"

[[services]]
  http_checks = []
  internal_port = 8080
  processes = ["web"]
  protocol = "tcp"
  script_checks = []
  [services.concurrency]
    hard_limit = 25
    soft_limit = 20
    type = "connections"

  [[services.ports]]
    force_https = true
    handlers = ["http"]
    port = 80

  [[services.ports]]
    handlers = ["tls", "http"]
    port = 443

  [[services.tcp_checks]]
    grace_period = "1s"
    interval = "15s"
    restart_limit = 0
    timeout = "2s"

[[statics]]
  guest_path = "/app/public"
  url_prefix = "/"

When I deploy I get the following error:

Listening on http://0.0.0.0:8080

Any ideas here? I’m assuming I’m missing something super basic.

I fixed the scripts in the bin directory to set the current working directory a while back, but apparently neglected to update that page. Try:

[processes]
  web = "bin/rails fly:server"
  worker = "bin/bundle exec rake resque:work"

Thanks for the response. With that change I get the following build error:

I’m also struggling to deploy with resque. Did you ever get it working @arelplane?
