Ansible to set up a multi-node, multi-hypervisor devstack environment.

Sets up:

• a controller node without any compute hosts
• an ironic node with nova-compute, ironic services, and VMs that pretend to be bare metal.
• a virt node running nova-compute with the libvirt driver.

The point here is to be able to automate a deployment of this type so that we can test behaviors in this and similar configurations.

Current status: WIP, moving quickly. Goal status: works on newton and newer.

Assumes an account on Rackspace public cloud, with credentials configured in a clouds.yaml file and a pyrax configuration file. The OpenStack modules don't support Rackspace's DNS (because it isn't OpenStack), so we rely on the pyrax-based rax modules there. Also assumes a domain delegated to Rackspace's DNS servers, and either not associated with a Rackspace cloud account, or already associated with the cloud account configured for pyrax.

Usage

Copy secrets.yml.example to secrets.yml and edit as necessary.

Install the items in `requirements.txt`:

pip install --upgrade -r requirements.txt

Build the machines:

ansible-playbook -i inventory.yml build.yml

Destroy machines and private network:

ansible-playbook -i inventory.yml destroy.yml

Initial stack user setup via root access:

ansible-playbook -i inventory.yml -u root stack-user.yaml

Run devstack to do all the things:

ansible-playbook -i inventory.yml -u stack main.yml

TODO

• Disable root SSH ASAP
• Change root password ASAP
• Support private networks (and don't listen on non-private networks)
  • will need something on publicnet for UI/API
• Don't expose my inventory file, I guess
• move SWIFT_ENABLE_TEMPURLS=True and SWIFT_TEMPURL_KEY=secretkey to controller
• ironic subnodes don't do everything I need
  • create flavor
  • create/upload images
• ironic plugin is probably totally fucked
  • ya, rework this to check if resources exist, not if subnode
