Capistrano Tips

1. Production logs

namespace :logs do
  desc "tail rails logs. Usage cap production logs:tail_rails"
  task :tail_rails do
    on roles(:app) do
      execute "tail -f #{shared_path}/log/#{fetch(:rails_env)}.log"
    end
  end
end

cap production logs:tail_rails

2. Commands in server

Add :

require 'capistrano/console'

to Capfile

Now you can run:

bundle exec cap production console

to run commands on the server terminal. Useful to run commands like: uptime.

3. Production rails console

Add:

gem 'capistrano-rails-console', require: false

to Gemfile and run bundle.

Add:

require 'capistrano/rails/console'

to Capfile.

Run:

cap production rails:console
