Can t fetch git repositories in puppet using ssh

Question

I have a requirement where I need to fetch git repositories using cron jobs via a specific user in Puppet. There's a private key located in my ~/.ssh directory, which I add to my ssh-agent with this exec:

  exec {
  'add-ssh-key':
    cwd => '/home/user/.ssh',
    command => "bash -c 'eval $(ssh-agent) ssh-add rsa_key'",
    path => '/usr/bin:/usr/sbin:/bin:/sbin',
    provider => 'shell'
  }

The agent started, but I cannot pull the repository ie. cron job doesn't execute, may be coz i'm not connected with the correct ssh agent.

What's the work around for this?

Answer 1

Try adding a section to the user's ~/.ssh/config file to instruct it to use the key when connecting to the git server.

Host my-git-server
    Hostname git.example.net
    User gituser
    IdentityFile /home/user/.ssh/rsa_key

Make sure that Puppet ensures the private key has appropriately limited permissions.There's no role of ssh-agent here.
