tomaszj / consul-dynamic-load-balancing

Playing with vagrant puppet, consul and dynamic load balancing

Requirements

In order to use this repo you need to have Vagrant and librarian-puppet installed.

• gem install librarian-puppet
• librarian-puppet install
• Download Vagrant

Running

If you have everything installed you can create and provision boxes, just

vagrant up

This will create 3 virtual machines - one server and two agents.

The server has got haproxy installed on port 8000 which is configured using consul. You can test load balancing by doing

curl localhost:8000

You should see Agent / Agent2 replies depending which backend is hit.

Known issues

You need to provision every time after booting the boxes - the firewall is not managed properly. Just run vagrant provision {server} or vagrant up {server} --provision and you should be good.
