Helper scripts for writing configuration files based on environment variables

Project description



This project is meant to provide utilities for writing out configuration files based on environment variables. Lots of projects seem to be implementing this on their own (Elasticsearch/Grafana), but it would be nice to have one thing that works for them we go!


Set your environment variables with a shared prefix. Section headers should be followed by a double underscore __


$ export MYPREFIX_foo__bar=baz
bar = baz

Check out the help text for current usage info too:

usage: [-h] -p PREFIX [-f {ini,json}]
                                     [-o OUTPUT_FILE] [-r REFERENCE_FILE]

Convert environment variables in to a configuration file

optional arguments:
  -h, --help            show this help message and exit
  -p PREFIX, --prefix PREFIX
                        Prefix of env vars to parse
  -f {ini,json}, --format {ini,json}
                        Output file format
  -o OUTPUT_FILE, --output-file OUTPUT_FILE
                        Outfile file path
  -r REFERENCE_FILE, --reference-file REFERENCE_FILE
                        Load this reference file for existing/hard coded
