`puma: restart 'calls twice, but I only call it once in my application to deploy via Capistrano?

Question

I tried to deploy the Rails application to the server through Capistrano. This is my deploy.rb code

set :repo_url, ' [e-mail] :varisdaOfficial/insurance_site.git' set :application, 'insurance_code' set :user, 'deploy' set :puma_threads, [4, 16] set :puma_workers, 0 set :pty, true set :use_sudo, false set :stage, :production set :deploy_via, :remote_cache set :deploy_to, "/home/#{fetch(:user)}/apps/#{fetch(:application)}" set :puma_bind, "unix://#{shared_path}/tmp/sockets/#{fetch(:application)}-puma.sock" set :puma_state, "#{shared_path}/tmp/pids/puma.state" set :puma_pid, "#{shared_path}/tmp/pids/puma.pid" set :puma_access_log, "#{release_path}/log/puma.error.log" set :puma_error_log, "#{release_path}/log/puma.access.log" set :ssh_options, { forward_agent: true, user: fetch(:user), keys: %w(~/.ssh/id_rsa.pub) } set :puma_preload_app, true set :puma_worker_timeout, nil set :puma_init_active_record, true # Change to false when not using ActiveRecord set :linked_dirs, %w(public/uploads) namespace :puma do desc 'Create Directories for Puma Pids and Socket' task :make_dirs do on roles(:app) do execute "mkdir #{shared_path}/tmp/sockets -p" execute "mkdir #{shared_path}/tmp/pids -p" end end before :start, :make_dirs end namespace :deploy do desc "Make sure local git is in sync with remote." task :check_revision do on roles(:app) do unless `git rev-parse HEAD` == `git rev-parse origin/master` puts "WARNING: HEAD is not the same as origin/master" puts "Run `git push` to sync changes." exit end end end desc 'Initial Deploy' task :initial do on roles(:app) do before 'deploy:restart', 'puma:start' invoke 'deploy' end end desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do invoke 'puma:restart' end end desc 'clear temp cache' task :clear_cache do on roles(:app) , in: :sequence, wait: 1 do execute "rm -rf #{shared_path}/tmp/cache/[^.]*" end end before :starting, :check_revision after :finishing, :compile_assets after :finishing, :cleanup after :finishing, :clear_cache after :finishing, :restart end 

So, when I started the “cap production” deployment, everything worked smoothly, my site can be successfully deployed, but after that I got a message.

 Capistrano tasks may only be invoked once. Since task `puma:restart' was previously invoked, invoke("puma:restart") at/Users/manjarb/.rbenv/versions/2.2.3/lib/ruby/gems/2.2.0/gems/capistrano3-puma-1.2.1/lib/capistrano/tasks/puma.rake:134 will be skipped. If you really meant to run this task again, first call Rake::Task["puma:restart"].reenable THIS BEHAVIOR MAY CHANGE IN A FUTURE VERSION OF CAPISTRANO. Please join the conversation here if this affects you. https://github.com/capistrano/capistrano/issues/1686 

I only call the reboot task once. So how can I fix this message?

Thanks!

Answer 1

I assume that you are using the capistrano3-puma gem. This gem automatically reloads puma for you at the end of a successful deployment. So this is the first time a restart task is called.

In addition, in your deploy.rb, you defined your own reboot task and you call it after :finishing . This is the source of the second call and therefore a warning.

To resolve this issue, remove the redundant task:

 desc 'Restart application' task :restart do on roles(:app), in: :sequence, wait: 5 do invoke 'puma:restart' end end 

And delete this:

 after :finishing, :restart
