Intro

Ansible plays to deploy OpenStack Havana with Neutron on RHEL 6.4+ or Fedora 19+
For OpenStack Grizzly deployments, please use grizzly branch

Status

• Havana
  • RHEL6.4+
    • RDO(Havana 2): stable
    • RDO(Havana 3): work in progress
    • RHOS40: developement - Check README-RHOS40
  • Fedora19+: work in progress

Notes

This work was initialy based from ansible-openstack.
Because of different deployment needs, for multi nodes approach, it has been almost entirely revisited.
Ultimately they will be merged back together.
Storage and HA are not supported yet but working on it.

Issues

Multiple Controllers doesn't work and will break the configuration. This should be taken care of with HA

Assumptions

1. Using 2 physical networks
2. A consistent network interface naming and configuration accross the environment.
   For instance:
   • eth1 is always external network
   • eth2 is always internal/data network

How To

1. Requirements
   • Ansible 1.2+ installed (epel6 for RHEL) on a system having ssh access to all your OpenStack target host(s)
   • Targetted hosts must have
     • RHEL6.4+ or Fedora 19+ installed
     • Either OpenStack repos
       • RHEL: RDO repo or RHOS 4.0
       • Fedora repo
     • Controller node(s) must have partition allocated for Cinder
   • If using RHOS, also consult README-RHOS40
2. Copy Ansible definitions to some directory:
   git clone https://github.com/gildub/arrod openstack
3. Create a your-hosts inventory file, use hosts-examples directory for templates:
   • All in one:
     1 x Controller/Network/Compute node
   • Controller and network service:
     N x controller(s), N x compute node(s)
   • All separate:
     N x controller(s), N x network node(s), N x compute node(s)
4. Edit group_vars values:
   • Passwords and secrets keys
   • Change cinder_volume_dev key accordingly with partition path and name
   • Neutron
     • Set neutron_external_interface and neutron_internal_interface keys, see Assumptions above
     • VLANs
       • Set provider_network_type: vlan
       • Set splinters: True if needed
     • GRE tunnels
       • Set provider_network_type: gre
5. Deploy
   1. From the ansible installed system, make sure you have ssh access to all hosts
      For instance have an ssh key installed on all hosts and use ssh-agent
   2. Run Ansible, using inventory file created above: cd openstack
ansible-playbooks -i ../your-hosts site.yml
   3. If it fails, address issue according to the message and re-run Ansible: wash, rince and repeat!
