### Generic Neutron Config
###

# Fatal Deprecations

# If ``neutron_api_workers`` is unset the system will use half the number of available VCPUs to
# compute the number of api workers to use with a default capping value of 16.

# If ``neutron_num_sync_threads`` is unset, the system will use the value of
# neutron_api_threads in templates/dhcp_agent.ini.j2 for num_sync_threads.
# neutron_num_sync_threads: 4

###
### DNSMasq configuration
###
# Dnsmasq doesn't work with config_template override, a deployer
# should instead configure its own neutron_dhcp_config key/values like this:
# neutron_dhcp_config:
#   dhcp-option-force: "26,1500"
neutron_dhcp_config: {}

# Dnsmasq has furthermore some options in its configuration that are not
# key/value pairs but just options. A deployer can configure those with this
# list:
neutron_dhcp_config_list: []

# Disable dnsmasq to resolve DNS via local resolv.conf.
# When dnsmasq_dns_servers are not set,
# and neutron_dnsmasq_noresolv is set to True, dnsmasq will reply with
# empty respose on DNS requests.

Dependencies

This role needs pip >= 7.1 installed on the target host.

Example playbook

---
- name: Installation and setup of Neutron
  hosts: neutron_all
  user: root
  roles:
    - role: os_neutron
      tags:
        - neutron-install
        - neutron-config
  vars:

Tags

This role supports two tags: neutron-install and neutron-config. The neutron-install tag can be used to install and upgrade. The neutron-config tag can be used to maintain the configuration of the service.
