Kubespray in Openstack does not allocate floating IP

[prateek2408]

Even after giving "--floating_ip" in the "kubesrpay openstack" command the Virtual machines that are created in openstack Cloud does not get a floating IP.

Also there is no option to provide the name of external network from which the floating IP would be taken and associated to Virtual machines . Setting auto_ip to true does not provide floating IP to the VM's

snippet-

                       'flavor': self.options['%s_flavor' % role],
                       'key_name': self.options['sshkey'],
                       'region_name': self.options['os_region_name'],
                       'auto_ip': self.options['floating_ip'],
                       'security_groups': [os_security_group_name],
                       'nics': 'port-name={{ item }}',

'image': self.options['image']

Kubespray Version - 2.3.0

The solution to this problem is to use floatingip_pools and provide the name of external network provided by user either is CLI or kubesrpay yaml file.

Here are the proposed changes in the cloud.py-

=================================

    if self.options['floating_ip']:
        ip_type = 'public'
        auto_ans = 'yes'
        pool_name = 'external' 

Here external pool would be replaced with the name of external network that is present in the Openstack environment, can be taken as command line argument or from config

=================================

=================================
self.pbook_content[0]['tasks'].append(
{'name': 'Provision OS %s instances' % role,
'os_server': {
'auth': openstack_auth,
'name': '{{item}}',
'state': 'present',
'flavor': self.options['%s_flavor' % role],
'key_name': self.options['sshkey'],
'region_name': self.options['os_region_name'],
#'auto_ip': auto_ans,
'floating_ip_pools': pool_name,
'security_groups': [os_security_group_name],
'nics': 'port-name={{ item }}',
'image': self.options['image']},
'register': 'os_%s' % role,
'with_items': os_instance_names}
