If I am not mistaken, 
You can configure your cloud/network to assign automatically floating IP to the VM.
This is related to the cloud and not to the nodepool

Hi!

* private ip is assigned without a problem automatically.

* VM is inaccessible from the external network using private IP, available from inside the private network. Which is normal, i think.  
When i manually assign public IP, machine is accessible via that public IP from elsewhere.

* This is the problem. I am a bit stuck debugging, because i do not see any failures in logs, except for "Timeout waiting for ssh access" in nodepool logs.

Here is some more info:

nodepool logs already have DEBUG enabled, at least according to logging.conf

[handler_debug]
level=DEBUG
class=logging.handlers.TimedRotatingFileHandler
formatter=simple
args=('/var/log/nodepool/debug.log', 'H', 8, 30,)


The only error i am getting is

ERROR nodepool.NodeLauncher: Timeout launching node id: 155 in provider: 
local_01 error: Timeout waiting for ssh access

but it is obvious why it is happening:

  DEBUG nodepool.TaskManager: Manager local_01 ran task ServerList in 0.138505220413s
  DEBUG nodepool.TaskManager: Manager local_01 running task PortList
(queue: 0)
  DEBUG nodepool.TaskManager: Manager local_01 ran task PortList in 0.0317981243134s
  DEBUG nodepool.TaskManager: Manager local_01 running task NeutronFloatingIPList (queue: 0)
  DEBUG nodepool.NodeLauncher: Node id: 155 is running, ipv4: 8.8.8.151, ipv6:.
  DEBUG nodepool.NodeLauncher: Node id: 155 testing ssh at ip: 8.8.8.151

It looks like nodepool assumes that private IP is the one, needed, and tries to access the instance using it, and i do not see any attempts to assign a public floating ip at all.

I tried adding "public: true/false" to networks field in nodepool.yaml and it did not help at all.
