Re: [openstack-dev] [Openstack] [Openstack-ansible] openstack ansible HA solution
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 On Wed, Apr 26, 2017 at 3:32 AM, Liyuenan (Maxwell Li) wrote: > Hi, all > > > > I have some questions about OSA project. > > > > 1.

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

[openstack-dev] [Openstack] [Openstack-ansible] openstack ansible HA solution
Hi, all I have some questions about OSA project. 1. OSA can install haproxy, but I can not found any other HA solution in openstack-ansible-haproxy_server, like keepalived or pacemarker. So how to making HAproxy high-available? 2. Could OSA support compute node high available? If my compute node down, could the instance on this node move to other nodes? Thank you! Best Regards!
