Copying Heroku Environment Variables Across Projects

under Devops

This article assumes you have the Heroku CLI installed and setup.

Copying Heroku config to local file

Using the Heroku CLI you can copy all of the config variables out of a project into a local file:

1heroku config -s -a {PROJECT_NAME} > config.txt

Setting values from local file into Heroku project

You can also do the opposite, push config values into a Heroku project:

1cat config.txt | tr '\n' ' ' | xargs heroku config:set -a {PROJECT}
