enable external network endpoint in tripleo
Hi, We are trying to install tripleo in our lab netwwork with 2 nic: 1) external network(172.16.141.0/24) 2) provicioning network(192.168.24.0/24)
So we have to enable external network endpoints so for that we use the undercloud.conf given below:
# Config generated by undercloud wizard
# Use these values in undercloud.conf
[DEFAULT]
undercloud_hostname = myhost.mydomain
local_interface = em1
local_mtu = 1500
network_cidr = 192.168.24.0/24
masquerade_network = 192.168.24.0/24
local_ip = 192.168.24.1/24
network_gateway = 192.168.24.1
undercloud_public_host = 172.16.141.149
undercloud_admin_host = 172.16.141.150
undercloud_service_certificate =
generate_service_certificate = False
scheduler_max_attempts = 10
dhcp_start = 192.168.24.4
dhcp_end = 192.168.24.15
inspection_iprange = 192.168.24.16,192.168.24.50
# Deprecated names for compatibility with older releases
discovery_iprange = 192.168.24.16,192.168.24.50
undercloud_public_vip = 172.16.141.149
undercloud_admin_vip = 172.16.141.150
We set undercloud_public_vip ,undercloud_admin_vip ,undercloud_public_host ,undercloud_admin_host to external network. But the openstack endpoint list only shows endpoint in 192.168.0/24 subnet.
Is there any other configuration that we need to do..please help.
Also whats the use of floating ip in overcloud nodes??
Thanks in advance
You need to have SSL/TLS configured in order to use public endpoint on the undercloud. Change
generate_service_certificate = Trueand then doopenstack undercloud upgrade. If unable to upgrade, re-install the undercloud.In short, the floating IP provides a 1-to-1 NAT on neutron router for the applied VM, so that external connections (e.g. from Internet) can reach the VM via a floating IP (which is a publicly routable one). It is the same as the "Elastic IP" in AWS.
thanks coby is the undercloud.conf correct other than generate_service_certificate = True??
Seems alright to me.
