Guide of Deploying Mult-nodes MAAS_JUJU_OPENSTACK using Bundle.

Hi all, I’m planning to deploy canonical charmed openstack using maas and juju. I was understand there are bundle/yaml script to automate the deployment. I need some clarification and further guidance. Hope you guyz able to assist further.

  1. Is the deployment of Canonical maas-juju-openstack must use bundle script? Can I just deploy maas and juju the traditional way of not using bundle? Any good reference for me to start?
  2. I want to deploy maas+juju in one cluster of 3 unit servers and openstack controllers in another cluster of 3 unit servers. Any specific spec of cpu, memory and storage is required? For now all my server specification is 3.2GHz, 2 socket of 24cores each, 1TB memory, 2x300GB HDD. Please advise if the spec is sufficient for my deployment?
  3. Where can I get a good ref of deployment of maas+juju and openstack using bundle, I feel lack of documentation and refrence of how the deployment should be done. Hopefully someone community able to help or at least guide how can I proceed further at least to deploy my first maas+juju cluster.

Thank you for help and you attention to my topic here, Thank you
