Restart Passenger/Rails 6 in Capistrano 3

[Scott Olmsted]

Not long ago I upgraded a Rails project I have maintained and enhanced since 2010 (!) from Rails 2 (!) to Rails 6. As part of the upgrade I moved up to Capistrano 3.

But I have not been able to get a deploy to restart Rails running under Passenger. I've tried two gems: 'capistrano-passenger' and 'capistrano-passenger-restart' and neither works though I see the task executed:

$ cap project1 deploy --trace

....

** Invoke deploy:restart (first_time)

** Execute deploy:restart

I've also tried executing a shell command to touch tmp/restart.txt with this task:

task :restart do

on roles(:app) do

within current_path do

execute :touch, 'tmp/restart.txt'

end

end

end

without success.

So if anyone is using Capistrano 3 and Passenger, how do you restart Rails after a deploy?

Thanks,

Scott
