i'm not sure problem here , don't see in docs capistrano , filters.

not sure other information relevant know here, if i've left out please let me know.

thanks!

capistrano 3's deploy task depends on task named deploy:restart. unlike other tasks in default deploy flow, behaviour of deploy:restart isn't predefined you; need customize depending on applications server use. when run cap install skeleton task created edit in capfile looks this.

desc 'restart application' task :restart   on roles(:app), in: :sequence, wait: 5     # restart mechanism here, example:     # execute :touch, release_path.join('tmp/restart.txt')   end end 

on roles(:app) tells capistrano execute method on servers gave app role in config/deploy/production.rb. think didn't assign servers role, capistrano complaining doesn't have anywhere run task. now, modify task run on role. however, predefined tasks related linked files , directories refer app role, if started using them (e.g. database.yml) capistrano throw error again. thus, think better choice give server app role.
