Capistrano: linked file database.yml does not exist on my.server.ipadress - ruby-on-rails

Question

after i try to deploy my app via capistrano to my server i get this error message:
DEBUG [605f198a] Finished in 0.084 seconds with exit status 1 (failed).
ERROR linked file /home/deploy/myrailsapp/shared/config/database.yml does not exist on xx.xxx.xx.xxx
(Backtrace restricted to imported tasks)
cap aborted!
SSHKit::Runner::ExecuteError: Exception while executing as deploy#xx.xxx.xx.xxx: exit
SystemExit: exit
Tasks: TOP => deploy:check:linked_files
(See full trace by running task with --trace)
The deploy has failed with an error: Exception while executing as deploy#xx.xxx.xx.xxx: exit
my deploy.rb is:
set :deploy_to, '/home/deploy/myrailsapp'
set :linked_files, %w{config/database.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
namespace :deploy do
desc 'Restart application'
task :restart do
on roles(:app), in: :sequence, wait: 5 do
execute :touch, release_path.join('tmp/restart.txt')
end
end
after :publishing, 'deploy:restart'
after :finishing, 'deploy:cleanup'
end
namespace :deploy do
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end
end
i tried this tut https://www.gorails.com/deploy/ubuntu/14.04, this is my first try with capistrano.

Just create /home/deploy/myrailsapp/shared/config/database.yml file manually and adjust it.
Capistrano doesn't create (or manage) configuration file out of the box. So, you should do it manually or automate use own Capistrano scripts, Puppet, Chef, Ansible tools.

As i prefer to have my files central on the deployment server, i use this task to deploy the config files from the config dir to the linked files dir on the app server.
This uses rsync, since i use capistrano-rsync to deploy.
namespace :deploy do
task :copy_config do
on release_roles :app do |role|
fetch(:linked_files).each do |linked_file|
user = role.user + "#" if role.user
hostname = role.hostname
linked_files(shared_path).each do |file|
run_locally do
execute :rsync, "config/#{file.to_s.gsub(/.*\/(.*)$/,"\\1")}", "#{user}#{hostname}:#{file.to_s.gsub(/(.*)\/[^\/]*$/, "\\1")}/"
end
end
end
end
end
end
before "deploy:check:linked_files", "deploy:copy_config"

You can upload files using the rake task.
Add the gem to your Gemfile after setting up Capistrano, preferably in the :development group:
group :development do
gem 'capistrano', require: false
gem 'capistrano-rake', require: false
end
Аdd it to your Capfile:
require 'capistrano/rake'
# Load custom tasks from `lib/capistrano/tasks` if you have any defined
Dir.glob("lib/capistrano/tasks/*.rake").each { |r| import r }
Create file lib/capistrano/tasks/setup.rake and add to it:
namespace :deploy do
namespace :check do
before :linked_files, :set_database_yml do
on roles(:app), in: :sequence, wait: 10 do
upload! 'config/database.yml', "#{shared_path}/config/database.yml"
end
end
end
end
