[Openstack-operators] Openstack-ansible and HAProxy

0 votes

Dear all,
Hope this is the right ML for this question, otherwise please let me know.

I have setup an openstack-ansible based infrastructure (pike) with 3 controllers and 8 computes. Everything works fine except when i configure a dedicated IP to be shared between the ctrls.

There are several bridges, but the one involved here are:
br-public (bridge toward internet)
I have one public ip for each ctrl (x.x.x.1, x.x.x.2, x.x.x.3) configured on each bridge
br-mgmt (default internal bridge for OS ansible setup)
I have one private ip for each ctrl (y.y.y.1, y.y.y.2, y.y.y.3) configured on each bridge
Then, I have configured the openstack-ansible files like:

lbvipaddress: y.y.y.1
I’m using the first ctrl ip for the internal network, but I’m not sure if it’s the right config
externallbvipaddress: x.x.x.4
I’m using a free IP in the public network to be shared by the controllers
keepalivedexternalvipcidr: "{{externallbvipaddress}}/24”
Here do I have to put /32 (default) or /24 (mi CIDR)?
haproxykeepalivedinternalvipcidr: "{{internallbvipaddress}}/24”
Here do I have to put /32 (default) or /24 (mi CIDR)?
keepalivedexternalinterface: br-public
haproxykeepalivedinternal_interface: br-mgmt

With netstat, I see HAProxy binding all the service ports in the ctrls, but I cannot ping (and access horizon or the other services) using the public ip x.x.x.4.

Any suggestion?

Thanks a lot,
