Adit Sarfaty 5dac3f4a4c NSX|v3: DHCP Relay support
Support DHCP relay by configuring the relay service per
network availability zone, or globally.
When a router interface port is created, the relay service
will be added to it.
DHCP traffic on the subnet will go through the DHCP server
configured in the dhcp relay service on the NSX, if it is
connected to the router.

Also add admin utility to update exsiting router ports when the
dhcp relay configuration changes.

A future patch will take care of firewall rules allowint the dhcp traffic.

Admin Utility

Introduction

Purpose of this script is to build a framework which can be leveraged to build utilities to help the on-field ops in system debugging.

Adding custom functions

Refer to the security groups example for reference implementation under, admin/plugins/nsx_v3/resources/securitygroups.py

Adding new functions is fairly straightforward:

  • Define the function under appropriate package. We use neutron callbacks to provide hooks. So your function definition should be like,
::

def function(resource, event, trigger, **kwargs)

  • Add the Resources and Operations enums if they don't exist.
::
class Operations(object):

NEUTRON_CLEAN = 'neutron_clean'

::
nsxv3_resources = {

constants.SECURITY_GROUPS: Resource(constants.SECURITY_GROUPS, ops)

}

  • In resource.py, add the function to the callback registry.
::
registry.subscribe(neutron_clean_security_groups,

Resources.SECURITY_GROUPS.value, Operations.NEUTRON_CLEAN.value)

  • To test, do
::

cd vmware-nsx/shell

sudo pip install -e .

nsxadmin -r <resource_name_you_added> -o <operation_you_added>

TODO

  • Use Cliff
  • Auto complete command line args.

Directory Structure

admin/

plugins/
common/

Contains code specific to different plugin versions.

nsx_v3/
resources/

Contains modules for various resources supported by the admin utility. These modules contains methods to perform operations on these resources.

Installation

::

sudo pip install -e .

Usage

::

nsxadmin -r <resource> -o <operation>

Example

::

$ nsxadmin -r security-groups -o list ==== [NSX] List Security Groups ==== Firewall Sections +------------------------------------------------+--------------------------------------+ | display_name | id | | default - 261343f8-4f35-4e57-9cc7-6c4fc7723b72 | 91a05fbd-054a-48b6-8e60-3b5d445be8c7 | | default - 823247b6-bdb3-47be-8bac-0d1114fc1ad7 | 78116d4a-de77-4a8f-b3e5-e76f458840ea | | OS default section for security-groups | 10a2fc6c-29c9-4d8d-ac2c-b24aafa15c79 | | Default Layer3 Section | e479e404-e712-4adb-879c-e432d510c056 | +------------------------------------------------+--------------------------------------+ Firewall NS Groups +------------------------------------------------+--------------------------------------+ | display_name | id | | NSGroup Container | c0b26e82-d49b-49f0-b68e-7449a59366e9 | | default - 261343f8-4f35-4e57-9cc7-6c4fc7723b72 | 2e5b5ca1-f687-4556-8130-9524b313474b | | default - 823247b6-bdb3-47be-8bac-0d1114fc1ad7 | b5cd9ae4-42b5-47a7-a1bf-9767ac62466e | +------------------------------------------------+--------------------------------------+ ==== [NEUTRON] List Security Groups Mappings ==== security-groups +---------+--------------------------------------+-----------------------------------------------------------+----------------------+ | name | id | section-uri | nsx-securitygroup-id | +---------+--------------------------------------+-----------------------------------------------------------+----------------------+ | default | f785c82a-5b28-42ac-aa0a-ad56720ccbbc | /api/4.0/firewall/globalroot-0/config/layer3sections/1006 | securitygroup-12 | +---------+--------------------------------------+-----------------------------------------------------------+----------------------+

Upgrade Steps (Version 1.0.0 to Version 1.1.0)

  1. Upgrade NSX backend from version 1.0.0 to version 1.1.0
  2. Create a DHCP-Profile and a Metadata-Proxy in NSX backend
  3. Stop Neutron
  4. Install version 1.1.0 Neutron plugin
  5. Run admin tools to migrate version 1.0.0 objects to version 1.1.0 objects
    • nsxadmin -r metadata-proxy -o nsx-update --property metadata_proxy_uuid=<UUID of Metadata-Proxy created in Step 2>
    • nsxadmin -r dhcp-binding -o nsx-update --property dhcp_profile_uuid=<UUID of DHCP-Profile created in Step 2>
  6. Start Neutron
  7. Make sure /etc/nova/nova.conf has metadata_proxy_shared_secret = <Secret of Metadata-Proxy created in Step 2>
  8. Restart VMs or ifdown/ifup their network interface to get new DHCP options
