How to change box name in Chef kitchen.yml? - vagrant

Question

I have created my kitchen.yml in the following way:
---
driver:
name: vagrant
customize:
memory: 2048
driver_config:
require_chef_omnibus: true
use_vagrant_berkshelf_plugin: true
provisioner:
name: chef_zero
chef_omnibus_url: http://box-url/install.sh
platforms:
- name: prod.abc.com
driver:
box_url: http://abc.box
run_list:
- role[new_role]
suites:
- name: default
In the above kitchen.yml, I get the hostname of the machine as default-prodabccom. However, I want the hostname to be prod.abc.com
What changes should i made in my kitchen.yml to get the correct name?

Answer 1

Hostname of the Guest System
In order to define the hostname of the operating system running inside the VM (cf. /etc/hostname), use the vm_hostname option of the kitchen-vagrant driver:
platforms:
- name: prod.abc.com
driver_config:
vm_hostname: prod.abc.com
Name of the Test-Kitchen Suite/Platform
To rename the suite-platform combination shown in Converging <default-prodabccom>, you can only play with name of suite and platform, i.e., to get production-abccom. This name is computed here in test-kitchen and, e.g., all dots are stripped, which cannot simply be changed.
Nevertheless, if I understand it right that you want to change this name: it makes little sense to me. Don't change that.
Name of the VM in VirtualBox
The name of the VM (e.g. kitchen-default-prodabcom_..default_1234..) is derived here in kitchen-vagrant and cannot easily be changed.

Answer 2

I found this question because I was in the scenario where I am testing a number of kitchen enabled repos, each containing a number of platforms. e.g.
elasticsearch
centos-6
centos-7
java
centos-6
centos-7
and you can give those machines their own ip by virtualbox when they are spun up like so;
driver:
name: vagrant
network:
- ["private_network", { type: "dhcp" }]
This facilitates testing, if something has failed and then you can get to the box directly. And you can use the vagrant HostManager plugin to keep your /etc/hosts updated with the current ip address.
So you can go http://default-centos-74.vagrantup.com in a local browser to check that instance. You can also name your suites in such a way that it leads to unique names for each each, across repos, for example prefixing each like so;
suites:
- name: elasticsearch-default
and in other other .kitchen.yml
suites:
- name: java-default
which still leads to useful naming;
http://elasticsearch-default-centos-74.vagrantup.com
However whats happended recently is that chrome and firefox have started to enforce HSTS which makes trying to get to non-HTTPS local sites, mapped using /etc/hosts a PITA.
The main thing is to get rid of the vagrantup.com suffix. However that is hard coded in, and the only option for over writing it is in .kitchen.yml which is unfortunate, because that doesn't know the suite and platform at the point it generates the Vagrantfile, so it's not much use.
You can use chef/ansible to rename the box, but that is not very nice. The solution I came up with is like this;
you can set a custom Vagrantfile.erb in .kitchen.yml ;
---
driver:
name: vagrant
network:
- ["private_network", { type: "dhcp" }]
vagrantfile_erb: Vagrantfile.erb
Then copy that Vagrantfile.erb out of the gem on your local box into the root of your test-kitchen repo. Mine was at /home/user1/.gem/ruby/gems/kitchen-vagrant-1.3.0/templates/Vagrantfile.erb
And then you set arbitrary names to your boxes by changing it at line 36;
c.vm.hostname = "<%= #instance.name %>.<%=
config[:kitchen_root].split('/')[-1] %>.testbox"
or you can modify it like so, and allow over riding from the .kitchen.yml config
36c36
< c.vm.hostname = "<%= config[:vm_hostname] %>"
---
> c.vm.hostname = "<%= #instance.name %>.<%= config[:var_domain] ? config[:var_domain] : config[:kitchen_root].split('/')[-1] %>.<%= config[:var_suffix] ? config[:var_suffix] : "vagrantup.com" %>"

And then you set arbitrary names to your boxes by setting var_suffix and var_domain in .kitchen.yml
---
driver:
name: vagrant
network:
- ["private_network", { type: "dhcp" }]
vagrantfile_erb: Vagrantfile.erb
#var_domain: sometingsomething
var_suffix: testbox
