Usage

Neutron is an OpenStack project to provide networking as a service between interface devices (e.g., vNICs) managed by other Openstack services (e.g., nova).

Starting with the Folsom release, Neutron is a core and supported part of the OpenStack platform (for Essex, we were an incubated project, which means use is suggested only for those who really know what they're doing with Neutron).

Sample Pillars

Neutron Server on the controller node

neutron:
  server:
    enabled: true
    version: mitaka
    allow_pagination: true
    pagination_max_limit: 100
    api_workers: 2
    rpc_workers: 2
    rpc_state_report_workers: 2
    root_helper_daemon: false
    dhcp_lease_duration: 600
    firewall_driver: iptables_hybrid
    bind:
      address: 172.20.0.1
      port: 9696
    database:
      engine: mysql
      host: 127.0.0.1
      port: 3306
      name: neutron
      user: neutron
      password: pwd
    identity:
      engine: keystone
      host: 127.0.0.1
      port: 35357
      user: neutron
      password: pwd
      tenant: service
      endpoint_type: internal
    message_queue:
      engine: rabbitmq
      host: 127.0.0.1
      port: 5672
      user: openstack
      password: pwd
      virtual_host: '/openstack'
    metadata:
      host: 127.0.0.1
      port: 8775
      password: pass
      workers: 2
    audit:
      enabled: false

Note

The pagination is useful to retrieve a large bunch of resources, because a single request may fail (timeout). This is enabled with both parameters allow_pagination and pagination_max_limit as shown above.

Configuration of policy.json file:

neutron:
  server:
    ....
    policy:
      create_subnet: 'rule:admin_or_network_owner'
      'get_network:queue_id': 'rule:admin_only'
      # Add key without value to remove line from policy.json
      'create_network:shared':

Neutron LBaaSv2 enablement

neutron:
  server:
    lbaas:
      enabled: true
      providers:
        octavia:
          engine: octavia
          driver_path: 'neutron_lbaas.drivers.octavia.driver.OctaviaDriver'
          base_url: 'http://127.0.0.1:9876'
        avi_adc:
          engine: avinetworks
          driver_path: 'avi_lbaasv2.avi_driver.AviDriver'
          controller_address: 10.182.129.239
          controller_user: admin
          controller_password: Cloudlab2016
          controller_cloud_name: Default-Cloud
        avi_adc2:
          engine: avinetworks
          ...

Note

If the Contrail backend is set, Opencontrail loadbalancer would be enabled automatically. In this case lbaas should disabled in pillar:

neutron:
  server:
    lbaas:
      enabled: false

Neutron FWaaSv1 enablement

neutron:
  fwaas:
    enabled: true
    version: ocata
    api_version: v1

Enable CORS parameters

neutron:
  server:
    cors:
      allowed_origin: https:localhost.local,http:localhost.local
      expose_headers: X-Auth-Token,X-Openstack-Request-Id,X-Subject-Token
      allow_methods: GET,PUT,POST,DELETE,PATCH
      allow_headers: X-Auth-Token,X-Openstack-Request-Id,X-Subject-Token
      allow_credentials: True
      max_age: 86400

Neutron VXLAN tenant networks with Network nodes

With DVR for East-West and Network node for North-South.

This use case describes a model utilising VxLAN overlay with DVR. The DVR routers will only be utilized for traffic that is router within the cloud infrastructure and that remains encapsulated. External traffic will be routed to via the network nodes.

The intention is that each tenant will require at least two (2) vrouters one to be utilised

Disable physnet1 bridge

By default we have external access turned on, so among any physnets in your reclass there would be additional one: physnet1, which is mapped to br-floating

If you need internal nets only without this bridge, remove br-floating and configurations mappings. Disable mappings for this bridge on neutron-servers:

neutron:
  server:
    external_access: false

gateways:

neutron:
  gateway:
    external_access: false

compute nodes:

neutron:
  compute:
    external_access: false

Add additional bridge mappings for OVS bridges

By default we have external access turned on, so among any physnets in your reclass there would be additional one: physnet1, which is mapped to br-floating

If you need to add extra non-default bridge mappings they can be defined separately for both gateways and compute nodes:

gateways:

neutron:
  gateway:
    bridge_mappings:
      physnet4: br-floating-internet

compute nodes:

neutron:
  compute:
    bridge_mappings:
      physnet4: br-floating-internet

Specify different mtu values for different physnets

Configuring TLS communications

Note

By default, system-wide installed CA certs are used, so cacert_file param is optional, as well as cacert.

  • RabbitMQ TLS

             (optional) cacert: cert body if the cacert_file does not exists
             (optional) cacert_file: /etc/openstack/rabbitmq-ca.pem
             (optional) version: TLSv1_2
  • MySQL TLS

    neutron:
      server:

Enhanced logging with logging.conf

By default logging.conf is disabled.

That is possible to enable per-binary logging.conf with new variables:

  • openstack_log_appender
    Set to true to enable log_config_append for all OpenStack services
  • openstack_fluentd_handler_enabled
    Set to true to enable FluentHandler for all Openstack services
  • openstack_ossyslog_handler_enabled
    Set to true to enable OSSysLogHandler for all Openstack services.

Only WatchedFileHandler, OSSysLogHandler, and FluentHandler are available.

Also it is possible to configure this with pillar:

neutron:
  server:
    logging:
      log_appender: true
      log_handlers:
        watchedfile:
          enabled: true
        fluentd:
          enabled: true
        ossyslog:
          enabled: true
  ....
  compute:
    logging:
      log_appender: true
      log_handlers:
        watchedfile:
          enabled: true
        fluentd:
          enabled: true
        ossyslog:
          enabled: true
  ....
  gateway:
    logging:
      log_appender: true
      log_handlers:
        watchedfile:
          enabled: true
        fluentd:
          enabled: true
        ossyslog:
          enabled: true

Logging levels pillar example:

neutron:
  server:
    logging:
      log_appender: true
      loggers:
        root:
          level: 'DEBUG'
        neutron:

        amqplib:
