Rubbe ec2r : Unable to connect with ssh

Question

I followed the railscasts and with basic configurations such as image_id: ami-3f32ac3e (Ubuntu Server 12.04.3 LTS 64 bit), app_name: myapp, app_user: jashwant , I tried to deploy with rubber.

Everything went smooth. I now have a running instance, but at the end I am getting Trying to enable root login * 2013-11-09 17:03:33 executing `rubber:_ensure_key_file_present' * 2013-11-09 17:03:33 executing `rubber:_allow_root_ssh' * executing "sudo -p 'sudo password: ' bash -l -c 'mkdir -p /root/.ssh && cp /home/ubuntu/.ssh/authorized_keys /root/.ssh/'" servers: ["54.238.122.222"] ** Failed to connect to 54.238.122.122, retrying * 2013-11-09 17:03:37 executing `rubber:_ensure_key_file_present' * 2013-11-09 17:03:37 executing `rubber:_allow_root_ssh' * executing "sudo -p 'sudo password: ' bash -l -c 'mkdir -p /root/.ssh && cp /home/ubuntu/.ssh/authorized_keys /root/.ssh/'" servers: ["54.238.122.122"]

You can see the error here

I concluded from here that, I need to set :initial_ssh_user in config/deploy.rb

I already saw, set :user, 'root' set :password, nil in config/deploy.rb

So, I added set :initial_ssh_user, 'ubuntu'. But the error remains the same.

If I change set :user, 'root' to set :user, 'ubuntu', then I get Trying to enable root login * 2013-11-09 17:13:48 executing `rubber:_direct_connection_54.238.122.122_411' * executing "echo" servers: ["54.238.122.122"] ** Failed to connect to 54.238.122.122, retrying

Things I have checked after googling:

1. It's not happening because Amazon instance is still starting. I have waited long after the instance has started. Also, I get the same error when I do ALIAS=production cap rubber:refresh

2. I am able to successfully log in to this new instance via ssh (providing username as ubuntu ). So, key file is okay.

3. I have already added the key with ssh-add

4. Key file in .ec2 directory does not have .pem extension.

5. I do not have duplicate entries in my etc/hosts on Amazon instance.

Answer 1

It turned out that rubber wasn't able to read from private key. I fixed that and it worked.
