Capistrano 3 Wordpress deployment with cap staging deploy on bitbucket fails

Question

I am trying to do a Capistrano 3 deploy for my Wordpress setup as per this screencast I am deploying to an ubuntu 12.04 server

So here is my deploy.rb file:

set :application, 'dladv'
set :repo_url, 'git@bitbucket.org:username/repo.git'

set :branch, proc { `git rev-parse --abbrev-ref HEAD`.chomp }

set :deploy_via, :copy
set :deploy_to, '/var/www/php/domain' # I have set the correct permissions with www:data group and added stager as member of this group

set :log_level, :debug
set :pty, true

set :linked_dirs, %w{uploads}

# set :default_env, {}


namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app) do
      sudo "apache2ctl", "graceful", "-v"
    end
  end

end

And my staging.rb looks like this:

set :stage, :staging

server 'staging.domain.com', user: 'stager', roles: %w{web app db}, port: 47

# set it globally
set :ssh_options, {
 keys: %w(/home/stager/.ssh/id_rsa),
 forward_agent: true,
 auth_methods: %w(password)
}

Now when I try to do cap staging deploy --trace, I get:

Tasks: TOP => git:check => git:wrapper

1. I have added my imac's ssh/id_ra.pub key to the server's authorized_keys file and
2. I have generated ssh-keygen -t rsa -C "myemail@gmail.com" on the server and then added that key to both my github account and my bitbucket account
3. I have verfied with bitbucket on the server with ssh -T hg@bitbucket.org

I don't know why it keeps saying Authentication failed for user stager@staging.domain.com Please help

Answer 1

try with this:

set :user, 'your_deploy_user_name'

set :ssh_options, {
   user: fetch(:user)
}

this works for me
