In a capistrano deploy of a Ruby-on-Rails project the deployment fails and aborts with a fatal error. The message is
A branch named 'deploy' already exists.
Of course the branch already exists, because we are trying to deploy that branch. Any idea what goes wrong? This is the log, we are using Git, the capistrano branch is set to deploy, the capistrano version is 2.15.9, ruby version is 2.3.1

The command that fails is git checkout -q -b deploy sha_value.
It turns out deploy is a reserved name for Capistrano, so you are not allowed to use it as a branch name. Capistrano apparently tries to create a temporary "deploy" branch if you deploy a Git project.
https://github.com/capistrano/capistrano/issues/359
In general "deploy", "doctor", and "install" are all reserved names in Capistrano, which are also not allowed as stage names (such as "production" or "staging").

When trying to deploy a Rails app to a production server with Capistrano, it doesn't seem to recognize my project as being a git repo, despite me having cloned the project directly from GitHub.

During deploys to various environments, capistrano3 creates a directory tree and puts the git information in a folder called repo_path. You'd have to travel inside that directory on your production server and "$git log" would work indicated its a .git repo
You also shouldn't need .git in your copy_exclude.
Try running through the capistrano3 set up process all over again with your app for different environments.
Here is the command I'm giving to deploy my code to a server.
$ cap production deploy:migrations
* executing `production'
triggering start callbacks for `deploy:migrations'
* executing `multistage:ensure'
* executing `deploy:migrations'
* executing `deploy:update_code'
triggering before callbacks for `deploy:update_code'
* executing `dj:stop'
* executing "RAILS_ENV=production god stop dj"
servers: ["xyz.com"]
connection failed for: xyz.com (ArgumentError: non-absolute home)
I am able to ssh into xyz.com. My capistrano version is
$ cap --version
Capistrano v2.5.19
And it is dependant on net-ssh-2.1.3. The ruby version is ruby 1.9.2p290
Read through similar questions in Stackoverflow, all seem to are suggesting a check on /etc/passwd file in the server. I checked the file and ENV['HOME'] is correctly set for the ssh user.
HOME variable in Server.
$ echo $HOME
/home/deploy
HOME has always been like this from the start. Why would it fail all of a sudden.
Anyone facing the same issue?
I want to deploy my project with capistrano. Here is my settings file:
deploy.rb
require "capistrano/ext/multistage"
require "capistrano_colors"
require "bundler/capistrano"
require "rvm/capistrano" # Load RVM"s capistrano plugin.
set :application, "project"
set :copy_exclude, %w(.git .gitignore doc features log spec test tmp Capfile)
#set :shared_children, shared_children + %w(public/uploads)
set :use_sudo, false
set :user, "app"
set :stages, %w(staging production)
namespace :deploy do
task :start, roles: :app, except: { no_release: true } do
run "cd #{current_path} && bundle exec unicorn_rails -c config/unicorn.rb -E #{rails_env} -D"
end
task :stop, roles: :app, except: { no_release: true } do
run "kill -KILL -s QUIT `cat #{shared_path}/pids/unicorn.pid`"
end
task :restart, roles: :app, except: { no_release: true } do
stop
start
end
end
def confirm
puts "\n\e[0;36m#{stage}\e[0m\e[0;31m Do you really deploy? (yes/no) \e[0m\n"
proceed = STDIN.gets rescue nil
exit unless proceed.chomp! == "yes"
end
For the multistage, I have created two files (one by environment):
deploy/production.rb
server "myserver.net", :app, :web, :db, primary: true
set :rails_env, "production"
set :rvm_type, :user
set :rvm_ruby_string, "ruby-2.0.0-p0"
set :scm, :git
set :repository, 'ssh://xxxx#11.111.111.111:54333/~/git-workspace/myproject.git'
set :deploy_via, :remote_cache
confirm
and almost the same for the staging one.
( As you have guessed, I have changed project, server name and port number for security purposes)
I first executed :
bundle exe cap production deploy:check
then :
bundle exe cap production deploy:setup
without any problem, when calling the deploy command (bundle exe cap production deploy), i get the below message :

I have generated keys (in my local environment) and put the public one in the authorized_keys file (server side).
You seem to have taken a lot of the right steps, so now with this kind of error, you should test the permissions directly:
Ensure that you can ssh from your development machine (where you're running capistrano) to the deployment server as that user. (E.g., that might be something along the lines of ssh deploy#myserver.com.
Once you've made sure that works, then while logged in on the server, as the deployment user, try connecting to the repository server. E.g., something like ssh -T git#github.com as described here.
99% of the time, if you can do these two things successfully, there will be no permissions problems.
I am new to deploying rails websites using capistrano.
I pushed my changes to the git repository successfully without getting any error.
Now I need to push the same changes to the production server using Capistrano.
When I run cap deploy I get the following error:

I tried to do a Google search but am having a bit of trouble finding a good answer
Would seem your remote installation lacks git.
Have you tried doing a
cap deploy:check
To check the environment and a
cap deploy:setup
To setup the required files?
I finally figured it out.
I just switched to a new Mac that didn't have Xcode installed. This is why Macports was not working correctly. I installed Xcode and after that, I am now able to deploy just fine.
