Hello guys,

I am trying to deploy a Rails app to Ubuntu server (nginx, unicorn) with using Capistrano 3.

Here’s the setup:

Capfile:

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'

Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }

deploy.rb

lock '3.2.1'

set :application, 'myappname'
set :scm, :git
set :repo_url, 'git@bitbucket.org:username/repo.git'
set :branch, "master"

set :format, :pretty
set :pty, true

set :log_level, :info

set :linked_files, %w{config/database.yml config/config.yml}
set :linked_dirs, %w{bin log tmp vendor/bundle public/system}

set :keep_releases, 5

production.rb;

set :stage, :production
set :branch, "master"

role :app, %w{deployer@IP}
role :web, %w{deployer@IP}
role :db,  %w{deployer@IP}

server "IP", user: "deployer", roles: %w{web}, primary: true

set :deploy_to, "/home/deployer/apps/myappname"
set :rails_env, :production

set :ssh_options, {
    forward_agent: true,
    auth_methods: %w(password),
    password: 'pass',
    user: 'deployer',
    port: 22
}

set :enable_ssl, false

When I run cap production deploy, I get this error message:

The deploy has failed with an error: #<SSHKit::Runner::ExecuteError: Exception while executing on host IP: exit>

Any tips how to solve this issue? I get successfully SSH to the server, but through Capistrano, I am receiving this error message.

I’d be happy for every tip to help me out with this issue!

Thanks!

Is ‘IP’ just a placeholder, or is that you actually have in your configs?

server “IP”, user: “deployer”, roles: %w{web}, primary: true

This should be your actual ip address
