Re: [openstack-dev] [Openstack] [Openstack-ansible] openstack ansible HA solution

[Logan V.]

Hello,

Yes openstack-ansible does support deploying keepalived along with
haproxy. The keepalived role is run just before the haproxy role in
this playbook: 
https://github.com/openstack/openstack-ansible/blob/master/playbooks/haproxy-install.yml#L27-L31

You can see an example keepalived configuration in the prod config
example of the OSA deployment guide:
https://docs.openstack.org/project-deploy-guide/openstack-ansible/draft/app-config-prod.html#user-variables

Re: [openstack-dev] [Openstack] [Openstack-ansible] openstack ansible HA solution

[Ignazio Cassano]

Hi, I wrote my own ansible recipe to deploy openstack in HA where haproxy
is a pacemaker resource .
As far as vm high availability is concerned there are some suggestions in
openstack ha guide .
