Capistrano puma jobs does nothing - capistrano

Question

I am trying to perform some puma actions using cap, and it does nothing.
For example:
cap production puma:config
This is my deploy.rb:
lock '3.10.1'
set :application, 'AppName'
set :repo_url, '#########git.......' # Edit this to match your repository
set :branch, ENV['BRANCH'] if ENV['BRANCH']
set :user, 'root'
set :deploy_to, '/home/root/AppName'
set :pty, true
#set :linked_files, %w{config/application.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system public/uploads}
set :keep_releases, 5
set :rbenv_ruby, '2.4.1'
set :puma_rackup, -> { File.join(current_path, 'config.ru') }
set :puma_state, "#{shared_path}/tmp/pids/puma.state"
set :puma_pid, "#{shared_path}/tmp/pids/puma.pid"
set :puma_bind, "unix://#{shared_path}/tmp/sockets/puma.sock" #accept array for multi-bind
set :puma_conf, "/home/root/GlucoMeDDC/current/config/puma.rb"
set :puma_access_log, "#{shared_path}/log/puma_error.log"
set :puma_error_log, "#{shared_path}/log/puma_access.log"
set :puma_role, :app
set :puma_env, fetch(:rack_env, fetch(:rails_env, 'production'))
set :puma_threads, [1, 1]
set :puma_workers, 3
set :puma_worker_timeout, nil
set :puma_init_active_record, true
set :puma_preload_app, true
## Defaults:
# set :scm, :git
# set :branch, :master
# set :format, :pretty
# set :log_level, :debug
# set :keep_releases, 5
## Linked Files & Directories (Default None):
# set :linked_files, %w{config/database.yml}
# set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
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 '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
after :finishing, :compile_assets
after :finishing, :cleanup
after :finishing, :restart
end
# ps aux | grep puma # Get puma pid

Returns nothing, just empty row.
