NOTE The quickest and easiest way to take Juju for a spin is by using http://conjure-up.io. But if you are like me and want to delve into and meddle with the underlying details this guide is for you!

Inception

Deploy OpenStack in a OpenStack cloud using Juju 2.0

• Bundle is based on https://jujucharms.com/openstack-base/
• Altered to deploy services to individual instances instead of the original behaviour of creating 4 machines with services in LXD containers
  • TODO: It is probably possible to make the default behaviour work even when deploying on OpenStack. Have to figure out plumbing for the LXD networking within OpenStack instances
• Scripts used to manage life cycle of Neutron ports for neutron-gateway units
  • TODO: Implement this in bundle using Juju Spaces

Prerequisites

• Running OpenStack cloud
• DNS setup to resolve/access new instances by name
  • Either
    • Designate set up to integrate with Nova and Neutron
    • serverstack-dns
      • https://launchpad.net/~openstack-charmers/+archive/ubuntu/test-tools

Instructions

1. Launch Ubuntu Xenial instance, load OpenStack credentials

2. Add Juju devel PPA

   sudo add-apt-repository ppa:juju/devel
   sudo apt-get update
   sudo apt-get install juju
   

3. Add cloud to Juju

   cat << EOF > mycloud.yaml
   clouds:
     mycloud:
       type: openstack
       auth-types: [access-key, userpass]
       regions:
         myregion:
           endpoint: https://192.0.2.10:5000/v3
   EOF
   

   juju add-cloud mycloud mycloud.yaml
   

4. Bootstrap Juju

   cat << EOF > config.yaml
   image-metadata-url: https://198.51.100.10:443/swift/v1/simplestreams/data/
   agent-metadata-url: https://streams.canonical.com/juju/tools/
   agent-stream: devel
   default-series: xenial
   EOF
   

   juju bootstrap mycloud myregion --config config.yaml
   

5. Check status and tail log

   juju status
   juju debug-log
   

6. Add UUID of your projects network to deploy.sh

7. Run it

   ./deploy.sh
   

8. Get coffee, tea, (popcorn?) or whatever you favor to do while waiting for computers

9. profit!

10. Destroy it

    ./destroy.sh
