Hi Alex,
	Please set DEBUG level in nodepool to see more info
Few questions:
	Do you get private ip?
	Can you ping the vm?
	What is the failure?

Subject: [OpenStack-Infra] [nodepool] unable to get a floating IP

Hello!

I am setting up a CI instance and currently face a problem with auto-assigning floating IPs.

Instances are started, no error in /var/log/nodepool/debug.log, but floating ip is not assigned and nodepool tries to access instance via private ip, and it fails obviously.

Manual IP assigning both from cli and horizon works without any problems.

I am using nodepool 0.4.0 + zookeeper.

Here is my nodepool provider config:

     username: '***'
     password: '***'
     auth-url: 'http://****:5000/v2.0'
     project-name: 'openstackci'
     max-servers: 4
     pool: public-net
     clean-floating-ips: true
     networks:
       - name: net2
     images:
       - name: oracle7
         min-ram: 8192
         diskimage: oracle7
         username: jenkins
         private-key: '/home/nodepool/.ssh/id_rsa'

targets:
   - name: jenkins1


net2 - is a private network, public-net is a pool of floating ips on public network,

net2 is connected to public network through router. Manual VM creation on net2 and assigning a floating IP works without any problems.
