When bandwidth fails you - building a remote Test Kitchen development environment.

· Read in about 2 min · (365 Words)

Last week, I was in a hotel with incredibly brutal internet and I really wanted to update my Consul cookbook.

I tried for a while, but when it looked pretty hopeless I started to try some remote cloud providers to see if I could speed things up. Rackspace and AWS were no go since they use Xen behind the scenes - which doesn’t work with VirtualBox - so I tried Digital Ocean - and it got farther than anybody else.

After an Vagrant ssh login failure, a hint from @michaelpgoetz and a comment from @GermanDZ I tried the kitchen-docker driver for Test Kitchen. It worked, and it seemed to work really well.

I now had a VM to work on my cookbook - and I wasn’t limited to 25K / second download speeds anymore. Yay!

Here’s the cookbook that I built to create that Test Kitchen development VM - tkdevenv-cookbook.

You can build your own image on Digital Ocean by, installing Packer, exporting a few environment variables:

# Digital Ocean - get these here:
export DIGITALOCEAN_CLIENT_ID="long-random-string"
export DIGITALOCEAN_API_KEY="another-long-random-string"


git clone
cd tkdevenv-cookbook
# Edit attributes/default.rb to put in your own name and email address
bundle install
rake build_droplet

Once that’s built, any time you need it, you can create an environment to use very easily. I will use the tugboat gem in this example:

[master] darron@~/Dropbox/src/tkdevenv-cookbook: tugboat sizes
512MB (id: 66)
1GB (id: 63)
2GB (id: 62)
4GB (id: 64)
8GB (id: 65)
16GB (id: 61)
32GB (id: 60)
48GB (id: 70)
64GB (id: 69)
[master] darron@~/Dropbox/src/tkdevenv-cookbook: tugboat images
My Images:
tkdevenv (May 5, 2014) (id: 3550834, distro: Ubuntu)
[master] darron@~/Dropbox/src/tkdevenv-cookbook: tugboat keys
SSH Keys:
darron (id: 52104)
[master] darron@~/Dropbox/src/tkdevenv-cookbook: tugboat create testkitchen -s 62 -r 1 -i 3550834 -k 52104
Queueing creation of droplet 'testkitchen'...done

Now you have your very own Test Kitchen development environment “as a Service” (TKDEaaS), available in about 60 seconds. Perfect for those really terrible internet connection days.

NOTE: I only have 1 unresolved minor problem so far - Serverspec seems to fail for running processes - probably because of Docker. Haven’t looked into it in detail yet - I just ignored that failure for now.
