# Occasionally I want to see the application properties that are pulled down from the Spring Cloud Config service that provides 
# content to our Spring Boot apps.  Since I seem to have to re-discover this every time, I figured I'd write it down to help me
# remember.

# Additional docs can be found here: https://cloud.spring.io/spring-cloud-config/single/spring-cloud-config.html

# To see the output in YML format

# How to install `ipkg` on a Synology DS214

After a couple of days of trying to get `ipkg` woking on my DS214 I found [this article](https://github.com/trepmag/ds213j-optware-bootstrap) by [trepmag](https://github.com/trepmag). It is written for the DS213j, but it’s been working for me and [others](https://github.com/alberthild) for the DS214 too. 

I have done some minor changed to clarify some things, but if you are a Linux guy (unlike me) my changes might be of no use to you. 


## Guide

1. Setup a project

2. Add groovy SDK support:
https://www.bonusbits.com/wiki/HowTo:Add_Groovy_SDK_to_IntelliJ_IDEA

3. Download http://(yourjenkinsurl)/job/(yourpipelinejob)/pipeline-syntax/gdsl
- this will give you the .gdsl file - download this to the src folder of your project.

4. Finally follow this step - right click on the src folder -> Mark directory as -> Sources Root
