This file describes how to use Vagrant (http://www.vagrantup.com) to
|
|
create a devstack virtual environment that contains two nova instances
|
|
running a simple web server and a working Neutron LBaaS Version 2 load
|
|
balancer backed by Octavia.
|
|
|
|
1) Install vagrant on your host machine. Vagrant is available for
|
|
Windows, Mac OS, and most Linux distributions. Download and install
|
|
the package appropriate for your system. On Ubuntu, simply type:
|
|
|
|
sudo apt-get install vagrant
|
|
|
|
2) copy 'Vagrantfile' from this directory to any appropriate directory
|
|
|
|
mkdir $HOME/lbaas-octavia-vagrant # or any other appropriate directory
|
|
cp -rfp $HOME/lbaas-octavia-vagrant
|
|
|
|
3) Continue either by the single node deployment (6GB RAM minimum), or by the
|
|
multinode deployment (12GB RAM minimum).
|
|
|
|
Single node deployment
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
1) Create and deploy the environment VM
|
|
|
|
cd $HOME/lbaas-octavia-vagrant/single
|
|
vagrant up
|
|
|
|
Alternatively, you can specify the number of vcpus or memory:
|
|
VM_CPUS=4 VM_MEMORY=8192 vagrant up
|
|
|
|
2) Wait for the vagrant VM to boot and install, typically 20-30 minutes
|
|
|
|
3) SSH into the vagrant box
|
|
|
|
vagrant ssh
|
|
|
|
4) Continue on the common section below
|
|
|
|
Multinode
|
|
~~~~~~~~~
|
|
|
|
This will create an environment where the octavia services are replicated
|
|
across two nodes, and in front of the octavia api, an haproxy is configured
|
|
to distribute traffic among both API servers, and provide failure tolerance.
|
|
|
|
Please note that the database is a single mysql instance, with no clustering.
|
|
|
|
1) Create and deploy the environment VMs
|
|
|
|
cd $HOME/lbaas-octavia-vagrant/multinode
|
|
vagrant up main
|
|
|
|
2) Wait for the main node to be deployed, and then start the second node
|
|
|
|
vagrant up second
|
|
|
|
3) Log in to the main node, and run local-manual.sh now that everything is
|
|
deployed
|
|
|
|
vagrant ssh main
|
|
cd devstack
|
|
./local-manual.sh
|
|
logout
|
|
|
|
4) SSH in any of the vagrant boxes:
|
|
|
|
vagrant ssh main
|
|
vagrant ssh second
|
|
|
|
4) Continue on the common section bellow
|
|
|
|
Common to multinode and single node
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
1) Determine the loadbalancer IP:
|
|
|
|
source openrc admin admin
|
|
openstack loadbalancer show lb1 -f value -c vip_address
|
|
|
|
2) make HTTP requests to test your load balancer:
|
|
|
|
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.
