m-creations/velocity-renderer

A velocity template render tool which can use to replace environment variables in given velocity template files. It can be useful for calling inside Docker container at run-time.

Velocity Renderer

Introduction

We needed a simple tool which would allow us to replace values of environment variables in files and would work as a Java library and as a command line tool.

Apache Velocity is a mature and reliable Java template engine which we chose as the basis for this small utility.

How to use

After checkout, build it with maven:

mvn clean install

You can run it with following command inside the project root folder:

java -jar target/velocity-renderer-standalone.jar -s ./src/test/resources -f .*.vm -d ./target

After that you can see the rendered file at target/sample.test:

cat target/sample.test

To see the template, from which sample.test was generated:

cat src/test/resources/sample.test.vm
