junocfg

Template based config generator / settings files merge tool

Installation

go get github.com/gojuno/junocfg/...

Usage

Modes:

• merge - merge config data from multiply sources to one dataset
• check-tmpl

merge multiply config files to one

$ junocfg --merge -i public.yaml,secure.yaml -o settings.yaml

$ junocfg --merge -i public.yaml,secure.yaml > settings.yaml

generate template from settings file

$ junocfg -t config.yaml.tmpl -i settings.dev.yaml -o config.yaml

$ cat settings.dev.yaml | junocfg -t config.yaml.tmpl > config.yaml

check tmpl

$ junocfg --check-tmpl -t config.yaml.tmpl
$ cat config.yaml.tmpl | junocfg --check-tmpl

full pipiline / generate template from multiply config files

merge config data from multiply sources to one dataset and apply it to template

$ junocfg --merge -i public.yaml,secure.yaml | junocfg -t config.yaml.tmpl > config.yaml

convert between json & yaml

echo '{"a":"a","b":["b1","b2","b3","b4"],"c":{"ca":"ca","cb":["cb1","cb2",{"cb3a":"cb3aa"},"cb4",{"cb5a":"cb5aa"}]},"d":"a","e":{"ea":"ea","eb":"eb","ec":"ec"}}' | junocfg --yaml2json | jq '.'

echo '{"a":"a","b":["b1","b2","b3","b4"],"c":{"ca":"ca","cb":["cb1","cb2",{"cb3a":"cb3aa"},"cb4",{"cb5a":"cb5aa"}]},"d":"a","e":{"ea":"ea","eb":"eb","ec":"ec"}}' | junocfg --json2yaml

Test

junocfg --merge -i examples/a.yaml,examples/b.yaml

junocfg --check-tmpl -t examples/c.tmpl
cat examples/c.tmpl | junocfg --check-tmpl

echo '{"a":"a","b":["b1","b2","b3","b4"],"c":{"ca":"ca","cb":["cb1","cb2",{"cb3a":"cb3aa"},"cb4",{"cb5a":"cb5aa"}]},"d":"a","e":{"ea":"ea","eb":"eb","ec":"ec"}}' | junocfg --yaml2json | jq '.' | junocfg --json2yaml
