Generates a Google credential file based on Heroku Config Vars.
This is useful when using a package such as @google-cloud/storage which loads credentials from a file instead of an environmental variable.
This repository is a fork from elishaterada/heroku-google-application-credentials-buildpack. It fixes some bugs that I found during my usage of the original repository.
- Create Config Vars key
GOOGLE_CREDENTIALS
and paste the content of service account credential JSON file as is. - Create a key under Config Vars
GOOGLE_APPLICATION_CREDENTIALS
and set a value asgoogle-credentials.json
.
The script with generate a file called google-credentials.json
which holds the key from the step #1 above.
