I am getting following error while deploying Rails 4 application using Capistrano 3

Here is capistrano configuration.
config/deploy.rb
# config valid only for current version of Capistrano
lock '3.4.0'
set :application, 'magnificent'
set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'
set :deploy_to, '/home/deploy/magnificent'
set :linked_files, %w{config/database.yml config/secrets.yml}
set :linked_dirs, %w{bin log tmp/pids tmp/cache tmp/sockets vendor/bundle public/system}
set :branch, 'develop' #set/ :branch,`git rev-parse --abbrev-ref HEAD`.chomp
set :ssh_options, { forward_agent: true }
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
namespace :deploy do
after :restart, :clear_cache do
on roles(:web), in: :groups, limit: 3, wait: 10 do
# Here we can do anything such as:
# within release_path do
# execute :rake, 'cache:clear'
# end
end
end
end
production.rb
set :stage, :production
server 'xx.xx.xx.xx', user: 'deploy', roles: %w{web app}
Capfile
require 'capistrano/setup'
require 'capistrano/deploy'
require 'capistrano/rvm'
require 'capistrano/bundler'
require 'capistrano/rails'
require 'capistrano/rails/assets'
require 'capistrano/rails/migrations'
Dir.glob('lib/capistrano/tasks/*.rake').each { |r| import r }
set :rvm_type, :user
set :rvm_ruby_version, '2.2.2'
I also copied /home/deploy/.ssh/id_rsa.pub of remote server to github deploy keys.
UPDATE
I confirm that I am able to access remote repo and also GIT_ASKPASS=/bin/echo GIT_SSH=/tmp/magnificent/git-ssh.sh /usr/bin/env git ls-remote --heads git@github.com:BoTreeConsultingTeam/magnificent.git
command works on remote server.
Current Solution
Lately I use different solution. Before cap production deploy
I run following commands.
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_rsa
Previous Solution
I am able to fix this issue by replacing
set :repo_url, 'git@github.com:BoTreeConsultingTeam/magnificent.git'
with
set :repo_url, 'https://my_github_username:my_github_password@github.com/BoTreeConsultingTeam/magnificent'
Note if your password contains special characters then thet should be url encoded. You can quickly encode using URI::encode
in irb.
With other deployments using Capistrano 2, I never need to supply github credentials.
Can anybody please tell why should I have to specify git username/password in repo_url
?
There is one more solution in the upcase forum post which also worked.
I had this problem too. Turns out I had loaded the wrong SSH key and it interfered with the deployment. Solved it by removing the wrong loaded ssh key like so:
ssh-add -d ~/.ssh/wrong-ssh-key
and then running the Capistrano deployment again.
I had similar problem(ubuntu). ssh-agent should be on. You can add it to startup applications.
This could also happen if you are deploying to the server for the first time, and the git server is not in the known host list of your deployment server.
so, logging into the remote server and then doing a git request to the repository will cause the git server to be added to the known host list.
like so:
git ls-remote git@bitbucket.org:your_gitbucket_user_id/your_repo.git master
The authenticity of host 'bitbucket.org (104.192.143.2)' can't be established.
RSA key fingerprint is SHA256:zzXQOXSRBEiUtuE8AikJYKwbHaxvSc0ojabwzha.
Are you sure you want to continue connecting (yes/no)? yes
you should confirm to connect.
Warning: Permanently added 'bitbucket.org,104.192.143.2' (RSA) to the list of known hosts.
Now try deploying using the capistrano task.
cap production deploy
