How can I set Pipelines environmental variables from my Python code inside my Pipelines script?

I have set my an environmental variable in my setup.py script and I would like to access this in my Pipelines script.

os.environ["MY_PKG_VERSION"] = str(version)

The thing is every time I echo this in my Pipelines script

- echo $MY_PKG_VERSION

nothing shows up.  I tried creating an unsecured environmental variable in Pipelines (Settings->Pipelines->Environmental Variables) and accessed it via Python to update it, but this doesn't update it despite it working locally.

import os
import re

# Update the current version to the new version
current_version = os.environ['MY_PKG_VERSION']
release_version = int(re.sub(".\d+$", "", current_version))
patch_version = int(re.sub("^\d+.", "", current_version))
new_patch_version = patch_version + 1
new_version = "%d.%d" % (release_version, new_patch_version)

# Set version number as environmental variable
os.environ['MY_PKG_VERSION'] = new_version

print(current_version)
print(new_version)

If $MY_PKG_VERSION is set to 0.1, then current_verision==0.1 and new_version==0.2.  This script is run via Pipelines without failing and the print() outputs are displaying the correct values.

Ideally, I would be able to use the environmental variable set in my Python code within the Pipelines script by concatenating it to another string.

Any ideas on how to go about achieving this?

Cheers,

Grant

Hello,

I am looking for changing the "APPLICATION_ENVIRONMENT" directly in bitbucket-pipelines.yml. Any idea how to do that?

 

We have specific branches that need to de deployed on specific environment on AWS Beanstalk?

 

Thank you for your help.

Hi Grant,

Bitbucket Pipelines environment variables are currently immutable. So you are unable to modify them during your build. 

In regards to having the version numbers, you should follow this issue for updates: https://bitbucket.org/site/master/issues/12838/build-number-that-increments-on-every

If you need a unique identifier for you version and are okay with it not being an ordered number, you can use the environment variable $BITBUCKET_COMMIT.

Are there any other use-cases for you where you would want to modify an environment variable, or just for version numbers?

Thanks,

Phil

My use case is purely for modifying the version number, which is pretty critical. I see the ticket was opened six months ago. Is Atlassian intended to add the feature of either setting environmental variables or having an auto incriminating version number attainable also as an environmental variable?
