Deploying Rails App with Capistrano - "ERROR: Repository not found."

Question

I'm having trouble using Capistrano to deploy a Rails app to an EC2 instance. I am developing the new app for my work on my personal laptop. I have two Github accounts (personal and work). I tried to add my personal public key but Github refused because my personal Github account was already associated with it. So, as a result I have two sets of private/public keys on my laptop.

I added my work public key (~/.ssh/work_rsa.pub) to my work Github account. I created a new private repository under a Github Organization (referred to as WorkOrg) that my work Github account owns (I'm an admin user in that org).

Then I had to create an alias so that git would use my work private key when pushing to Github. Here's how my ~/.ssh/config looks:

# work account
Host github.com-work
   HostName github.com
   User git
   IdentityFile ~/.ssh/work_rsa

I then had to change the remote origin url to: git@github.com-work:WorkOrg/work_reports.git so that I could run $ git push without having to supply my username and password info every time. So, I can now push/pull just fine in this new repo (work_reports) on my laptop.

I also setup an EC2 instance (ubuntu 14.04) and created a user deploy that I can SSH into (using the same ~/.ssh/work_rsa key). I copied over my work_rsa into /home/deploy/.ssh/work_rsa so that I could push/pull from that EC2 instance.

I'm now ready to use Capistrano to setup automated deployments to my EC2 instance. When I run $ cap production deploy:check --trace it fails after this:

DEBUG [943f7c42]    and the repository exists.

Here's my Capfile:

require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/rbenv'
set :rbenv_type, :user 
set :rbenv_ruby, '2.2.2'

Here's my /config/deploy.rb file:

lock '3.2.1'
set :application, 'work_reports'
set :deploy_user, 'deploy'
set :scm, :git
#set :repo_url, 'git@github.com-work:WorkOrg/work_reports.git'
set :repo_url, 'git@github.com:WorkOrg/work_reports.git'
set :branch, ENV['REVISION'] || ENV['BRANCH'] || "master"
set :ssh_options, { forward_agent: true, paranoid: true, keys: "~/.ssh/work_rsa" }
set :deploy_to, '/home/deploy/work_reports'
set :linked_files, %w{config/database.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}

namespace :deploy do

  desc 'Restart application'
  task :restart do
    on roles(:app), in: :sequence, wait: 5 do
      execute :touch, release_path.join('tmp/restart.txt')
    end
  end

  after :publishing, 'deploy:restart'
  after :finishing, 'deploy:cleanup'
end

And here's my /config/deploy/production.rb file:

set :stage, :production
server 'xx.xxx.xxx.xxx', user: 'deploy', roles: %w{web app db}

I even tried using the aliased remote origin url (set :repo_url, 'git@github.com-work:WorkOrg/work_reports.git') in the deploy.rb file but I got the same error.

Is there something I'm not configuring properly so that I can deploy my Rails app to EC2 using Capistrano?

Answer 1

Late in the train here.

My problem turned out to be changed repo name. This was fixed when I SSH'd to the server, then changed the repo URI in git config located at /to/project/repo/config.

Weird thing that this was only happening in Travis CI build. Also, no problem when I checked with capistrano-ssh-doctor.

Answer 2

I had to change my /config/deploy.rb file in order for Capistrano to actually use the work_rsa private key :

set :ssh_options, { forward_agent: false, paranoid: true, keys: "~/.ssh/work_rsa" }
