Capistrano unable to pull a Stash repository using SSH

I followed the following procedure:

  • Created an SSH key;
  • Enabled SSH in Atlassian Stash;
  • Added SSH key for the Stash account called Capistrano (already used by Capistrano to successfully connect using username and password to Stash)
  • Tested the SSH connection using the command git clone ssh://[email protected]:7999/project/repository.git and the repository is successfully cloned;
  • Changed the following line to config/deploy.rb in Capistrano project directory: set :repo_url, 'ssh://[email protected]:7999/project/repository.git'

The problem is that executing the command cap production git:check I get the following error lines and the deployment is cancelled:

I already tried to simply change the variable to set :repo_url, 'ssh://[email protected]:7999/project/repository.git' but I receive the same error. Anyone successfully connecting Capistrano to Stash via SSH? Could you please suggest how I can debug it? I would like to avoid to use usernames and passwords in my Capistrano configuration files.

Solution

  • A simplistic answer, but I would guess that Capistrano is picking up the wrong key. I'd suggest that you check the default ssh key for the deployment user. So, if capistrano is set to log into the server using deployuser, see what key deployuser picks up. It can be helpful to test with ssh -T [email protected] -p 7999 and see what comes back.
