[MD IRSHAD ALAM]

I want to create a port with fixed ip. The same yaml file is successfully created the port on kilo ubuntu version but when i'm going to use same yaml file in liberty centos it will throws an error:

heatclient.exc.HTTPBadRequest: ERROR: Property error: : resources.my_port.properties.fixed_ips[0].ip_address: : "10.0.0.20" does not validate ip_addr (constraint not found)

Below is the yaml file:

heat_template_version: 2013-05-23
description: Simple template to deploy a single compute instance
parameters:

resources:
  my_port:
    type: OS::Neutron::Port
    properties:
      name: "port1"
      network_id: "<network-id>"
      fixed_ips: [{"ip_address": 10.0.0.20}]

workaroud:

File: /usr/lib/python2.7/site-packages/heat/engine/resources/openstack/neutron/port.py
Function: class Port(neutron.NeutronResource):

comment the line as below:

FIXED_IP_IP_ADDRESS: properties.Schema(
                        properties.Schema.STRING,
                        _('IP address desired in the subnet for this port.')
                        #_('IP address desired in the subnet for this port.'),
                        #constraints=[
                        # constraints.CustomConstraint('ip_addr')
                        #]
                    ),

I think your constraints plugins are not registered properly. May be you've upgraded and your upgrade is not clean. Please check you setup.cfg where plugins entrypoints are there. I think we changed these entrypoints in liberty.

Hi. Tried this template on liberty, validation is going fine. Can you share contents of your setup.cfg in heat? And contents of heat.egg-info/entry_points.txt.

Hi,
It resolves the issue after installing the package "python-croniter" using yum install python-croniter. But according to official document http://docs.openstack.org/liberty/install-guide-rdo/heat.html there is no such detail about this package.

Dmitriy i have installed the heat on my openstack setup using the below document-
