templated

Dockerized (but not only) simple config generator from templates and JSON data using Jinja2

May collect (and merge) configuration data from JSON URL (including webdis, http://firebase.com or local etcd, for example), files, strings and generate config (but not only) files from template files/URLs.

Simple example

docker run --rm \
    -v /etc/someconf:/data \
    $IMG_NAME \
    /templated.py -v \
        -u http://myfirebase.com/conf/conf1.json \
        -u http://myfirebase.com/conf/conf2.json \
        -T http://myfirebase.com/tpl/test2.tpl \
        -s '{"key":"mysecretkey1"}' \
        -o test1.conf \
        -p 0600 \
        -s '{"key":"mysecretkey2"}' \
        -o test2.conf

This example write in folder /etc/someconf 2 files using template test2.tpl and data from conf1.json and conf2.json

• test1.conf with permissons 0644
• test2.conf with permissons 0600 and different key value

Limitation

Any JSON data must be object (not string or bare array)
