fakecloud

I wrote my first Mojolicious web app yesterday, a cloud-init meta-data server to enable running pre-built VM images (e.g. as provided by debian, ubuntu, etc) without having to install and manage a complete, full-featured cloud environment like openstack. I hacked up something similar several years ago when I was regularly building VM images at home for openstack at work, with just plain-text files served by apache, but that had pretty-much everything hard-coded. fakecloud does a lot more and allows per-VM …

Much more than I thought I would as an unrepentant sh and perl using systems geek. And getting over my distaste for the white-space issue is also proving to be much easier than I thought it would (although I still think that block-delimiters like {} make the code easier to read…PyHeresy, I …
