Multi-line config variables in Heroku

Question

I\'ve have a Rails app that loads a number of RSA certificates before a transaction is made with Paypal. On my development machine, these certificates are read from files in

Answer 1

If you want to set Heroku config values from your file contents, you can use the following shell trick:

$ heroku config:set SECRET_KEY="$(cat path/to/secret.key)"

Multi-line values can be set directly by putting quotes around the value:

$ heroku config:set SECRET_KEY='first line
> second line'

If you're using Foreman to run locally (now heroku local), it doesn't support multi-line variables. You must use something to inject them into the environment first, such as envdir:

$ envdir my-env-dir heroku local
