I am trying to setup a deployment from my local windows computer through gitlab to my server using capifony.

Usually I would connect by ssh to my server and run the command from the server Now I want to do it from my local computer.

I am already pushing code from my local computer to gitlab with git, i.e. my public key is registered on gitlab.

Here however, it's not working with capifony. What could be the issue ?

The error :

D:\Divers\Programmation\Web\foodmeup.dev>cap development deploy
 ** transaction: start
--> Updating code base with remote_cache strategy
*** [deploy:update_code] rolling back
 ** [deploy:update_code] exception while rolling back: Capistrano::ConnectionError, connection failed for: my_server_ip (ArgumentError: Could not parse PKey: no start line)
connection failed for: my_server_ip (ArgumentError: Could not parse PKey: no start line)

EDIT :

If I follow the instructions given in several post and I put in my deploy.rb the following options

ssh_options[:keys] = %w('~/.ssh/id_rsa')

or

ssh_options[:keys] = %w('~/.ssh/id_rsa.pub')

Then I am asked for a root password and I still get an error (despite the fact I can log in via ssh with putty directly and that running the deployment from my server with another user works without me entering the root password):

As mentioned in this issue, one possible reason is:

My problem was that I needed to enclose my ssh key file location in quotes in my config/deploy.rb file, like this:

ssh_options[:keys] = %w('~/.ssh/id_rsa.pub')

instead of:

ssh_options[:keys] = %w(~/.ssh/id_rsa.pub)

Also:

I got this error even when I dont set ssh_options[:keys] in my deploy.rb.

Or:

This problem may be caused by ssh private key with passphrase and no ssh public key.

(also mentioned in issues/101)

Try remove ssh_options[:keys] and invoke the following command:

ssh-keygen -y -f ~/.ssh/id_rsa > ~/.ssh/id_rsa.pub

That leads to:

I launched ProcessMonitor and found ruby process trying to load file ~.ssh\key.pub.pub which gave me an idea that path to the private (not public) key should be in ssh_config['keys'].

So this should work:

ssh_options[:keys] = %w('~/.ssh/id_rsa')
