Puppet learning VM

Learn / Spike (research) / Dev Puppet environment based on the official Puppet learning VM.

Puppet is an open-core software configuration management tool. It runs on many Unix-like systems as well as on Microsoft Windows, and includes its own declarative language to describe system configuration. It is written in C++, Clojure and Ruby, with its free-software version released under the Apache License 2.0 - wikipedia

Using the VM

Setup your environment (how many VMs you want)

cp vagrant.yaml.example vagrant.yaml

To spin up a puppet master:

vagrant up

To ssh into the box:

vagrant ssh learning

Once ssh into the learning VM you can get root by:

[vagrant@learning ~]$ sudo su -

You can retrieve the NAT (private IP) by:

facter networking.interfaces.eth1.ip

Or classic way:

root@learning: # ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group (...)
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:b9:88:bd brd ff:ff:ff:ff:ff:ff
    inet 10.0.2.15/24 brd 10.0.2.255 scope global noprefixroute dynamic eth0
       valid_lft 85677sec preferred_lft 85677sec
    inet6 fe80::752c:860f:3985:c1a2/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever
3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:68:fe:a9 brd ff:ff:ff:ff:ff:ff
    inet 172.28.128.8/24 brd 172.28.128.255 scope global noprefixroute dynamic eth1
       valid_lft 1048sec preferred_lft 1048sec
    inet6 fe80::a00:27ff:fe68:fea9/64 scope link 
       valid_lft forever preferred_lft forever
(...)

172.28.128.8 from eth1 is the IP that you care. Everytime you reboot the VM, you may get a different IP.

To list the available network interfaces:

nmcli d | grep connected | awk '{print $1}'
``


To use the [Quest Guide UI](https://github.com/puppetlabs/puppet-quest-guide), go to: http://172.28.128.8/ (replace with your own IP). You should be able to see:

Quest Guide for the Puppet Learning VM

To use the Puppet Console UI, go to https://172.28.128.8/ (replace with your own IP) and accept the self-signed certificate. You should be able to see:

Overview


Login using the default credentials:
* username: `admin`
* password: `puppetlabs`

### Alternative - using `hostmanager`

For this, you need to enable `hostmanager: true` in `vagrant.yaml`

To use the Quest Guide UI, go to: http://puppetmaster/. You should be able to see:

Quest Guide for the Puppet Learning VM

To use the Puppet Console UI, go to https://puppetmaster/ and accept the self-signed certificate. You should be able to see:

Overview


This is possible because on `linux` (if your machine is `linux`) or `macos`, for your convenience, `vagrant` will use the `hostmanager` plugin to add the node to your `/etc/hosts` file.

By default, the VM will be created in a NAT network, so `hostmanager` will use the internal routing to get to your node. The node is setup to use `dhcp` (by default). You can change this by modifying in `vagrant.yaml` the `private_ip` field.

The image is based on `CentOS Linux 7 (Core)` and the default clients are abstracted as `docker` containers.

## Generating the Learning VM vagrant box

<details>
  <summary>TODO</summary>
  Generate this image dynamically and create a Travis.CI Job to generate it.
</details>

Download latest `learning_puppet_vm.zip` and unzip it.

wget https://pe-education-vms.s3.amazonaws.com/learning/learning_puppet_vm.zip unzip learning_puppet_vm.zip

or for a specific version (e.g. `6.10`):
```bash
wget https://pe-education-vms.s3.amazonaws.com/learning/learning_puppet_vm-6.10.zip
unzip learning_puppet_vm-6.10.zip

After unziping it, there is an .ova image. Import it into VirtualBox:

VBoxManage import puppet-2019.0.2-learning-6.10.ova --vsys 0 --eula accept --vsys 0 --vmname "puppet-learning-vm-2019.0" --settingsfile "puppet-learning-vm"

List all your VMs and retrieve the puppet-learning-vm:

$ # list all your VMs
$ VBoxManage list --sorted vms
"puppet-learning-vm-2019.0" {28f73b71-7b70-4838-800b-d67400593594}
$ # list only the puppet-learning-vm-2019.0 VM
$ VBoxManage list --sorted vms | grep 'puppet-learning-vm-2019.0'
"puppet-learning-vm-2019.0" {28f73b71-7b70-4838-800b-d67400593594}
$ # list only the VM ID
$ VBoxManage list --sorted vms | grep 'puppet-learning-vm-2019.0' | awk '{print $2}' | cut -d '{' -f2 | cut -d '}' -f1
28f73b71-7b70-4838-800b-d67400593594

Package the VM:

vagrant package --base '28f73b71-7b70-4838-800b-d67400593594' --output puppet-learning-vm.box

Optimization: If you want to do it in oneshot, to get the VM UUID and package it as a .box (vagrant image) file:

vagrant package --base $(VBoxManage list --sorted vms | grep 'puppet-learning-vm-2019.0' | awk '{print $2}' | cut -d '{' -f2 | cut -d '}' -f1) --output puppet-learning-vm.box

Publishing the .box:

vagrant cloud publish --box-version 6.10-0 azbarcea/puppet-learning-vm-2019.0 --release --description "Puppet learning VM containing the Quest to learn (https://puppet.com/blog/quest-to-learn-puppet-new-learning-vm)" --short-description "Puppet learning VM for PE 2019.0" --version-description "Based on the official puppet-2019.0.2-learning-6.10.ova from learning_puppet_vm-6.10.zip" 6.10-0 virtualbox puppet-learning-vm-2019.0.box

The version 6.10-0 was used because 6.10 comes from the official puppet-2019.0.2-learning-6.10.ova (within learning_puppet_vm-6.10.zip) and 0 is the current .box packaging.

Known Issues

  • You need to enable virtualization in your BIOS for Virtualbox to work
  • On Windows, you need to disable Hyper-V from Windows Features for Virtualbox to work
  • Encountered issues when Guest GuestAdditions was upgraded. This depends on your host Virtualbox and how much is up-to-date.
GuestAdditions versions on your host (6.0.10) and guest (6.0.6) do not match

No IP for eth1

You'll see something like:

3: eth1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 08:00:27:68:fe:a9 brd ff:ff:ff:ff:ff:ff
    inet6 fe80::a00:27ff:fe68:fea9/64 scope link 
       valid_lft forever preferred_lft forever

In this case just restart the VM:

vagrant reload

Cannot access Puppet Console UI

That's because some services are broken. Get into VM and restart the services:

$ vagrant ssh learning
$ sudo su -
# systemctl restart pe-*
