Configuring for OpenStack
You should start by generating a generic configuration file for Juju, using the command:
juju generate-config -w
This will generate a file, environments.yaml, which will live in your ~/.juju/ directory (and will create the directory if it doesn't already exist).
The essential configuration sections for OpenStack look like this:
openstack:
type: openstack
# Specifies whether the use of a floating IP address is required to give the nodes
# a public IP address. Some installations assign public IP addresses by default without
# requiring a floating IP address.
# use-floating-ip: false
