Set a bunch of env vars on many CircleCI projects via API

readme.md

Usage

Update the yml files with the vars you want to set and which projects you want them set for.

If you haven't already done so, visit https://circleci.com/account/api and generate yourself an API token.

Edit the python script to replace YOUR_USER_NAME_HERE on line 11 with your actual Github org name.

python update-circleci-env.py YOUR_CIRCLE_API_TOKEN_HERE

circle.env.yml

AWS_ACCESS_KEY_ID: ABCDEFGHIJKLMNOPQRSTUVWXYZ
AWS_SECRET_ACCESS_KEY: supercalifragilisticexpialidocious
# more: values
# go: here

circle.projects.yml

projects:
  - Your
  - Projects
  - Here

update-circle-env.py

#!/usr/bin/env python

# NOTE 
# this will overwrite env vars on those projects!
