# Motivation

Modern dynamic infrastructure needs some config files that use environment variables, sometimes applications allow to use environment variable in configuration - some time no. This tool is single binnary application that pretty thin ~8Mb, its reduce docker image size, it's use golang templating engine for text processing

# Example of usage

```bash

cat << EOF > /tmp/go-template-example

{{ env "TEST_ENV" }}

EOF

# creates rendered file 

cat /tmp/go-template-example | TEST_ENV=test go-template > /tmp/go-template-example.txt

# check results

cat /tmp/go-template-example.txt

# for example it can be used for render all files in directory with .template file extension

for file in $(find /etc/nginx/conf.d/ /etc/nginx -name *.template -type f)

do

  dir=$(dirname $file)

  name=$(basename $file .template)

  cat $file | go-template > $dir/$name

done

```
