# Deploy in Gemfile
Gem 'capistrano ',' ~> 3.2.0'

Just complete the installation and generate the capfile...

$ Bundle exec cap install

Detailed Configuration:

$ Vim config/deploy/production. rb

# Content
11 server 'qzi. me', roles: [: demo], port: 1234, user: 'qzi'
12 task: uptime do | host |
13 on roles (: demo), in: parallel do

18 end

$ Cap production uptime

Better Syntax:

$ Vim config/deploy/production. rb

$ Vim lib/capistrano/tasks/test. rake

Desc "check the uptime on the host"
Task: uptime do | host |
On roles (: demo), in: parallel do
Uptime = capture (: uptime)
Hostname = capture (: hostname)
Puts "# {hostname} reports: # {uptime }"
End

End

$ Cap-T # Check your new command
