Open Stack

Regarding SSH Keys and logging into nodes, you need to set the NODEPOOL_SSH_KEY variable

1.       I documented my notes here https://github.com/rasselin/os-ext-testing-data/blob/master/etc/nodepool/nodepool.yaml.erb.sample#L48

2.       This is also documented ‘officially’ here: https://github.com/openstack-infra/nodepool/blob/master/README.rst

3.       Also, I had an issue getting puppet to do the right thing with keys, so it gets forced here: https://github.com/rasselin/os-ext-testing/blob/master/puppet/install_master.sh#L197

Thanks Patrick,
Indeed it seems the cloud provider was setting up vms on a bridge whose eth was DOWN so the vms could not connect to the outside world so the prepare script was failing.
Looking into that.

Thanks,

Eduard

Ah yea, sorry, should have specified; I am having it run the prepare_node_devstack.sh from the infra repo. I see it adding the same public key to the user specified in my nodepool.yaml. The strange part (and I need to double check.. feel like it can't be right) is that on my master node the nodepool users id_rsa changed at some point in the process.

Your image build needs to do _something_ to make SSH into the
resulting nodes possible. We accomplish that by applying a puppet
manifest which sets up an authorized_keys file for the account we
want it to use, but there are countless ways you could go about it
in your environment.
