Failure to restart puma after capistrano deployment

I'm trying to deploy a rails app from my machine to an aws linux ec2 using capistrano.

I used the bundle exec cap production deploy command and it actually deploys a new release to the server successfully but it fails to (re)start puma. At the puma restart phase I get this error (For privacy, I replaced the actual app name in the error with <app-name>):

01:23 puma:restart
      01 sudo /bin/systemctl restart puma_<app-name>_production
      01 Failed to restart puma_<app-name>_production.service: Unit puma_<app-name>_production.service not found.

You need to also do first: (Assuming you know where your service needs to go, if you are using the root user then place it in /etc/systemd/system/.service Then:

systemctl enable puma.service
systemctl start puma.service

You can then check the status using:

systemctl status puma.service

If it fails then you can do:

journalctl -xeu puma.service
or journalctl -u puma.service to check more log, then Ctrl+F to get to the bottom

It appears like you do not have a puma service unit file yet on your Production server. You can create one at, /etc/systemd/system/puma_<app-name>_production.service.

You should add a Unit entry into the service file. Refer to this, https://gist.github.com/arteezy/5d53d99f6ee617fae1f0db0576fdd418

Once you have created this. Next step is to test this service:

$ systemctl start puma_<app_name>_production.service 
$ systemctl status puma_<app_name>_production.service # Check status is running

In case the puma service doesn't start, thoroughly check the paths mentioned in your service file.

If this still persists, hope this unblocks you to make progress.
