This directory contains sample files for configuring neutron LBaaS using
|
||||
devstack. By copying these files into the main devstack directory (not the
|
||||
neutron-lbaas/devstack directory directly above this one), and running
|
||||
stack.sh, you will create a fully functioning OpenStack installation running
|
||||
a neutron-lbaas load balancer.
|
||||
|
||||
1) Copy the files into place:
|
||||
|
||||
cp local.conf local.sh webserver.sh <DEVSTACK_DIR>
|
||||
|
||||
where
|
||||
|
||||
<DEVSTCK_DIR> is the main devstack directory. Note: this is not
|
||||
neutron-lbaas/devstack.
|
||||
|
||||
2) Build your devstack:
|
||||
|
||||
cd <DEVSTACK_DIR>
|
||||
./stack.sh
|
||||
|
||||
3) Test your loadbalancer:
|
||||
|
||||
a) Determine the loadbalancer IP:
|
||||
|
||||
source openrc admin admin
|
||||
neutron lbaas-loadbalancer-show lb1 | grep vip_address
|
||||
curl <LB_IP>
|
||||
|
||||
where <LB_IP> is the VIP address for lb1. The subsequent invocations of
|
||||
"curl <LB_IP>" should demonstrate that the load balancer is alternating
|
||||
between two member nodes.

# Sample ``local.conf`` that builds a devstack with neutron LBaaS Version 2
|
||||
|
||||
# NOTE: Copy this file to the root DevStack directory for it to work properly.
|
||||
|
||||
# ``local.conf`` is a user-maintained settings file that is sourced from ``stackrc``.
|
||||
# This gives it the ability to override any variables set in ``stackrc``.
|
||||
# Also, most of the settings in ``stack.sh`` are written to only be set if no
|
||||
# value has already been set; this lets ``local.conf`` effectively override the
|
||||
# default values.
|
||||
|
||||
# The ``localrc`` section replaces the old ``localrc`` configuration file.
|
||||
# Note that if ``localrc`` is present it will be used in favor of this section.
