Appendix E. Using PLUMgrid Neutron Plugin
|
||||
-----------------------------------------
|
||||
|
||||
Installing Source and Host Networking
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
#. Clone the PLUMgrid ansible repository into the ``/opt`` directory:
|
||||
|
||||
.. code-block:: shell-session
|
||||
|
||||
# git clone -b TAG https://github.com/plumgrid/plumgrid-ansible.git /opt
|
||||
|
||||
Replace *``TAG``* with the current stable release tag.
|
||||
|
||||
#. PLUMgrid will take over networking for the entire cluster; therefore the
|
||||
bridges br-vxlan and br-vlan will only need to be present to avoid
|
||||
relevant containers from erroring out on infra hosts. They do not
|
||||
need to be attached to any host interface or a valid network.
|
||||
|
||||
#. PLUMgrid requires two networks, a Management and a Fabric network.
|
||||
Management is typically shared via the standard br-mgmt and Fabric
|
||||
must be specified in the PLUMgrid configuration file described below.
|
||||
Furthermore the Fabric interface must be untagged and unbridged.
|
||||
|
||||
Neutron Configurations
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
To setup the neutron configuration to install PLUMgrid as the
|
||||
core neutron plugin, create a user space variable file
|
||||
``/etc/openstack_deploy/user_pg_neutron.yml`` and insert the following
|
||||
parameters:
|
||||
|
||||
#. Set the ``neutron_plugin_type`` parameter to ``plumgrid`` in this file:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
# Neutron Plugins
|
||||
neutron_plugin_type: plumgrid
|
||||
|
||||
#. Also in the same file, disable the installation of all neutron-agents
|
||||
in the ``neutron_services`` dictionary, by setting their ``service_en``
|
||||
keys to ``False``
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||

|
||||
PLUMgrid Cofigurations
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
On the Deployment Host create a PLUMgrid user variables file, using the sample in
|
||||
``../playbooks/plumgrid-ansible/etc/user_pg_vars.yml.example`` and place it under
|
||||
``/etc/openstack_deploy/``. The following paremeters must be configured:
|
||||
|
||||
#. Replace ``PG_REPO_HOST`` with a valid repo URL hosting PLUMgrid
|
||||
packages.
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
plumgrid_repo: PG_REPO_HOST
|
||||
|
||||
#. Replace ``INFRA_IPs`` with comma seperated Infrastructure Node IPs and
|
||||
``PG_VIP`` with an anallocated IP on the management network, this will
|
||||
be used to access the PLUMgrid UI.
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
plumgrid_ip: INFRA_IPs
|
||||
pg_vip: PG_VIP
|
||||
|
||||
#. Replace ``FABRIC_IFC`` with the name of the interface that will be used
|
||||
for PLUMgrid Fabric. [Note: PLUMgrid Fabric must be an untagged unbridged
|
||||
raw inteface such as eth0]
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
fabric_interface: FABRIC_IFC
|
||||
|
||||
#. To override the default interface names with another name for any
|
||||
particular node fill in the ``fabric_ifc_override`` and ``mgmt_override``
|
||||
dicts with node ``hostname: interface_name`` as shown in the example file.
|
||||
|
||||
#. Obtain a PLUMgrid License file, rename to ``pg_license`` and place it under
|
||||
``/var/lib/plumgrid/pg_license`` on the Deployment Host.
|
||||
|
||||
Gateway Hosts
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
PLUMgrid enabled OpenStack clusters contain one or more Gateway Nodes
|
||||
that are used for providing connectivity with external resources such as
|
||||
external networks (Internet), bare-metal servers or network service
|
||||
appliances. In addition to the Management and Fabric networks required
|
||||
by PLUMgrid nodes, Gateways require dedicated external interfaces referred
|
||||
to as gateway_devs in the confgiuration files.
|
||||
|
||||
#. To add Gateways Hosts, add a ``gateway_hosts`` section to
|
||||
``/etc/openstack_deploy/openstack_user_config.yml`` as shown below:
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
gateway_hosts:
|
||||
gateway1:
|
||||
ip: GW01_IP_ADDRESS
|
||||
gateway2:
|
||||
ip: GW02_IP_ADDRESS
|
||||
|
||||
Replace ``*_IP_ADDRESS`` with the IP address of the ``br-mgmt`` container management
|
||||
bridge on each Gateway host.
|
||||
|
||||
#. Also add a ``gateway_hosts`` section to the end of the PLUMgrid ``user_pg_vars.yml``
|
||||
file described in the section above. This must contain hostnames and gateway_dev
|
||||
names for each Gateway in the cluster.
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
gateway_hosts:
|
||||
- hostname: gateway1
|
||||
gateway_devs:
|
||||
- eth3
|
||||
- eth4
|
||||
|
||||
Installation
|
||||
~~~~~~~~~~~~
|
||||
|
||||
#. Run the PLUMgrid playbooks with (do this before the openstack-setup.yml
|
||||
playbook is run):
|
||||
|
||||
.. code-block:: yaml
|
||||
|
||||
cd /opt/plumgrid-ansible
|
||||
openstack-ansible plumgrid_playbooks/plumgrid_all.yml
|
||||
|
||||
Note: Contact PLUMgrid for an Installation Pack info@plumgrid.com
|
||||
(includes full/trial license, packages, deployment documentation and
|
||||
automation scripts for the entire workflow described above)
