Re: How can I inject environment variables into my groovy class?

2017-12-04 Thread red 888
I guess it took longer than it should have to realize I was barking up the 
wrong tree, but let me explain why I wanted this.

I'm using the AWS java sdk. The AWS sdk looks for these env vars and pulls 
them in for creds automatically if they are set in the current session. Of 
course you can pass them in manually, but this feature is quite convenient! 
I'm calling the AWS SDK from a groovy class like this because its super 
portable and behaves almost like a lightweight jenkins plugin- I really 
like the idea of writing reusable api wrappers in groovy classes for the 
pipeline like this.

The GCP SDK has similar features where it looks for env vars for config.

It just would be nice to be able to define this once in the environment{} 
directive before calling these api wrapper classes.

2017-12-03 Thread Daniel Butler
If you’re dealing with a stubborn library that’s forcing you to use environment 
variables to pass in parameters you’re in for more pain than it’s worth trying 
to run it within the pipeline script environment.

Use it by running a groovy script externally, e.g.

sh “groovy MyScript.groovy”

and then you’ve got all the environment variables setup and you’re in a 
standard groovy environment without the pipeline restrictions and 
idiosyncrasies.

RE: How can I inject environment variables into my groovy class?

2017-12-01 Thread Daniel Butler
If you’re writing a groovy class that’s run from a library in the pipeline 
script then you’re not going to be able to use System.getEnv().

There’s a few approaches you can take that do work:
- You can pass in the values you need as parameters to the methods/constructors 
you’re using.
- In the pipeline there’s the global variable `env` which is a map of all the 
currently declared environment variables (JOB_NAME etc) you could pass into 
your class.
- Pass in `this` from the pipeline script. You can then use this object to 
access anything in pipeline, (Let’s assume you called the field/parameter ctx) 
i.e. ctx.env.JOB_NAME or ctx.powershell(“write-host ‘spooky’”)

I noticed also you’ve got a direct execution of a process commented out, don’t 
do that either. The same way System.getEnv() doesn’t work, doing that will not 
behave as expected either (Assuming the sandbox will let you)

Pipeline environment variables are not stored at the OS level. That's why
you are not able to get them using *System.getenv() *(which only list OS
level environment variables).
But you should be able to retrieve them like any other classical
environment variables : with the "${MyVar}" syntax inside your shared lib
class.

Hopefully it helps.
