deploy.rb

set :application, 'Psara'
set :repo_url, 'git@bitbucket.org:CBLaughter/psara.git'
set :deploy_to, '/home/Psara/Psara'
set :default_run_options, :pty => true

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

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

*

production.rb

set :stage, :staging
set :rails_env, :production

role :app, %w{sakura}
role :web, %w{sakura}
role :db, %w{sakura}

server 'sakura', user: 'Psara', roles: %w{web app}, my_property: >:my_value

set :ssh_options, {
keys: %w(~/.ssh/id_rsa),
forward_agent: false, }

I would be glad, if you could teach me what I can do to solve this problem.

I have already added a public key on the bitbucket, but it doesn't work.

It seems SSH agent forwarding is set up correctly! You can continue with the deployment process.

It succeeded in all tests, but still makes same error.

Answer 1

Make sure that you have ssh-agent running on your machine, because you're using ssh forwarding, your local keys should be able to access and clone your repo from bitbucket. You can run agent it with:

eval `ssh-agent`
ssh-add ~/.ssh/id_rsa

More info about ssh-forwarding you can find here.

Other thing you should check manually is that you can ssh to your server (your public key should be added to ~/.ssh/authorized_keys on server), and of course that you can clone your repo locally (that probably you're able to do).

Update:

Now i have realised that you turn forwarding for production, in that case you should make sure that key-pair that's on your server (you must have it, because forwarding is turned off), are able to clone repo from bitbucket, you can try cloning on server by hand too.
