Hi!
wow, I was reading about the subject of dynamic inventory. Actually it is
my first time with a setup so complex. My Vagrantfile is (based on work of
one guy, I don't remember now the link of github, apologies):
*# -*- mode: ruby -*-*
*# vi: set ft=ruby :*
*# Vagrantfile API/syntax version. Don't touch unless you know what you're
doing!*
*VAGRANTFILE_API_VERSION = "2"*
*cluster = {*
* "node1" => { :ip => "192.168.33.50", :cpus => 1, :mem => 1024 },*
* "node2" => { :ip => "192.168.33.51", :cpus => 1, :mem => 1024 },*
* "node3" => { :ip => "192.168.33.52", :cpus => 1, :mem => 1024 },*
*}*
*Vagrant.configure(VAGRANTFILE_API_VERSION) do |config|*
* #config.vm.box = "nrel/CentOS-6.5-x86_64"*
* #config.vm.box = "ubuntu/precise64"*
* cluster.each_with_index do |(hostname, info), index|*
* config.vm.define hostname do |cfg|*
* cfg.vm.provider :virtualbox do |vb, override|*
* config.vm.box = "ubuntu/precise64"*
* override.vm.network :private_network, ip: "#{info[:ip]}"*
* override.vm.hostname = hostname*
* vb.name = 'pxc-' + hostname*
* vb.customize ["modifyvm", :id, "--memory", info[:mem], "--cpus",
info[:cpus], "--hwvirtex", "on" ]*
* end # end provider*
* # provision nodes with ansible*
* if index == cluster.size - 1*
* cfg.vm.provision :ansible do |ansible|*
* #ansible.verbose = "vvvv"*
* ansible.extra_vars = { ansible_ssh_user: 'vagrant' }*
* ansible.inventory_path = "./inventory"*
* ansible.playbook = "playbook.yml"*
* ansible.limit = "local"*
* end # end provision*
* end #end if*
* end # end config*
* end # end cluster*
*end # end vagrant*
I don't know if it is the better way to do it, but at least it is the only
one that worked for me. I run a loop to provision all machines and then I
run playbook.yml.
Then in my inventory I have:
[local]
node1 ansible_ssh_host=192.168.33.50
node2 ansible_ssh_host=192.168.33.51
node3 ansible_ssh_host=192.168.33.52
son in my template I finally wrote:
% set iface = 'ansible_eth1' %}
wsrep_cluster_address = gcomm://{% for server in groups["local"] %}{{
hostvars[server][iface].ipv4.address }}{% if not loop.last %},{% endif %}{%
endfor %}
And worked perfectly!
Thanks a lot guys!
