Try to deploy rails app using Capistrano 3, when I run this command , get this error

vagrant@vagrant-ubuntu-utopic-32:/vagrant$ cap production deploy

i saw some posts [1,2]in stack overflow. but I am still getting error.

here is my Capfile:

require 'capistrano/setup'
set :stage, :production
require 'capistrano/deploy'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

deploy.rb file:

lock '3.4.0'
set :application, "career"
set :repo_url, "https://github.com/mezbahalam/offender_profile"

set :user, 'vagrant'
# set :scm_passphrase, "password"
set :deploy_to, "/home/vagrant/apps/career"
set :use_sudo, false
set :scm, :git
server "192.168.51.54",  roles: [:app, :web, :db], :primary => true 

what am I donig wrong?

Answer 1

Try setting up ssh keys for deployment. Make sure that your public key is in the list of authorized keys on the server and that it is chmod 600.

Answer 2

In my case I just had to run below command:

ssh-add

and then try command cap production deploy again. and it worked well.
