Subject: [Rdo-list] Deploying an HA dev environment with tripleo-quickstart
I'm working on a slightly more in-depth article on this topic, but in
order for some people (pmyers I'm looking at you) to get started I
wanted to write up some very quick instructions.
Could you be so kind to provide also setup for just
1.Controller
1.Compute
in overcloud ( as of now i7 4790 16 GB RAM)
Ansible based deployment schema. I have a chance to survive with 3VMs .
I think Lars has a page that describes this in good detail:

But the short answer to your question is to have a nodes.yml file that
looks like this:
-------------------------------------------------
extra_args: >-
--ntp-server pool.ntp.org
baremetal_vm_xml: |
<cpu mode='host-passthrough'/>
libvirt_args: --libvirt-type kvm
# Set these to values appropriate for your target system. You
# by default get three controllers, one compute node, and
# one ceph node (so this example has a memory footprint of
# 32GB, which is probably too much for a host with only
# 32GB of RAM).
control_memory: 8192
compute_memory: 4096
undercloud_vcpu: 2
url: file:///usr/share/quickstart_images/mitaka/undercloud.qcow2
overcloud_nodes:
- name: control_0
flavor: control
- name: compute_0
flavor: compute
-------------------------------------------------
