Trouble accessing LXC container

[Jay Pipes]

Hi all,

I've got a couple LXC containers running that I'm trying to experiment with Ansible on:

$ sudo lxc-ls --fancy
NAME         STATE    IPV4        IPV6  AUTOSTART 
-------------------------------------------------    
db           RUNNING  10.0.3.77   -     NO          
web          RUNNING  10.0.3.221  -     NO

And a hosts configuration as follows:

[web]
web ansible_ssh_user=ubuntu ansible_ssh_host=10.0.3.221

[db]
db ansible_ssh_user=ubuntu ansible_ssh_host=10.0.3.77


However, when I run my playbook, I'm getting errors trying to SSH to the containers:

http://paste.openstack.org/show/49894/

I can SSH to either IP address as the "ubuntu" user, but it asks for the password (also "ubuntu").

I'm not an SSH expert and I'm having trouble understanding what I need to do (either in my ~/.ssh/config or in Ansible environment variables) in order to get Ansible's SSH access working properly to these containers. Any help would be most appreciated, and sorry if this is a beginner question. I tried finding answers on the Google machine but was unsuccessful.

Do I need to log in to each container and configure SSH or inject an SSH key before I can use Ansible? Or is there a way that Ansible can do this somehow, perhaps with the virt Ansible module command(s)?

Best,

If you don't have a SSH key setup, you'll need to use --ask-pass (and have the askpass program installed) in order for it to prompt you for the password. You could write a play that deployed your key that way.

When creating a container (lxc-create) if your using the ubuntu or ubuntu-cloud template.. you can pass in an -S to pass a public key for future access. The ubuntu-cloud template also has support for -S on lxc-clone.
