Vagrant Multiple-VM Creation and Configuration

Automatically provision multiple VMs with Vagrant and VirtualBox. Automatically install, configure, and test Puppet Master and Puppet Agents on those VMs. All instructions can be found in my blog post: http://wp.me/p1RD28-1kX

JSON Configuration File

The Vagrantfile retrieves multiple VM configurations from a separate nodes.json file. All VM configuration is contained in the JSON file. You can add additional VMs to the JSON file, following the existing pattern. The Vagrantfile will loop through all nodes (VMs) in the nodes.json file and create the VMs. You can easily swap configuration files for alternate environments since the Vagrantfile is designed to be generic and portable.

Instructions

# on localhost
[+] vagrant up # brings up all VMs - slow!
vagrant ssh puppet.vm.local # coffee :-/

# test that puppet master was installed
[+] sudo service puppetmaster status
* master is running
[+] sudo puppet status info
Run mode 'user': local
[-] sudo service puppetmaster stop
[-] sudo puppet master --verbose --no-daemonize
# Ctrl+C to kill puppet master
sudo service puppetmaster start

# check for 'puppet' cert
[+] sudo puppet cert list --all

"node02.vm.local" (SHA256) 26:4C:7C:CB:6D:B8:27:49:CF:18:3E:CA:38:81:0A:95:79:4A:9E:67:9C:60:E3:1B:8E:A8:B2:A6:83:8D:7E:1C
+ "puppet.vm.local" (SHA256) 27:F3:D0:20:43:15:CB:6E:DF:00:06:D0:FB:5C:3C:6B:3A:8C:DD:0F:B7:2A:16:B8:00:4E:0A:68:68:ED:24:B8 (alt names: "DNS:puppet", "DNS:puppet.vm.local")

# setting up an agent for a *client*

# ssh into agent node

vagrant ssh node01.vm.local

# test that agent was installed
sudo service puppet status
* agent is running

sudo puppet agent --test --waitforcert=60 # initiate certificate signing request (CSR)

Back on the Puppet Master server (puppet.vm.local)

sudo puppet cert list # should see 'node01.vm.local' cert waiting for signature
[+] sudo puppet cert sign --all # sign the agent node(s) cert(s)
[+] sudo puppet cert list --all # check for signed cert(s)

Forwarding Ports

Used by Vagrant and VirtualBox. To create additional forwarding ports, add them to the 'ports' array. For example:

"ports": [
       {
         ":host": 1234,
         ":guest": 2234,
         ":id": "port-1"
       },
       {
         ":host": 5678,
         ":guest": 6789,
         ":id": "port-2"
       }
     ]
