Struggling with configuration drift? Create a single source of truth you can reference everywhere.
"Configuration drift occurs when a standardized group of IT resources, be they virtual servers, standard router configurations in VNF deployments, or any other deployment group that is built from a standard template, diverge in configuration over time. … The Infrastructure as Code methodology from DevOps is designed to combat Configuration Drift and other infrastructure management problems."
Create a single authoritative configuration file:
… that you can read directly into several languages or convert to other file formats (including YAML or JSON).
Sick of Turing-complete configuration languages? Dhall is
a
total programming language that forbids arbitrary side effects.
We take language security seriously so that your Dhall programs
never fail, hang, crash, leak secrets, or compromise your system.
The language aims to support safely importing and evaluating untrusted
Dhall code, even code authored by malicious users. We treat the inability
to do so as a specification bug.
Hold your configuration files to the same standard of
quality as the rest of your code.
"Configuration bugs, not code bugs, are the most common cause I've seen of really bad outages. … As with error handling, I'm often told that it's obvious that config changes are scary, but it's not so obvious that most companies test and stage config changes like they do code changes."
