bash - How to get environment variables in live Heroku dyno

There is a heroku config command but that apparently just shows me what the current setting is. I want to confirm in a dyno what my application is actually seeing in the running environment.

I tried heroku ps:exec -a <app> -d <dyno_instance> --ssh envand this has some generic output (like SHELL, PATH, etc.) output but it doesn't show any env vars that I've configured (like my db strings, for example). I've also tried directly logging in (using bash instead of the env command) and poked around but couldn't find anything.

Try heroku run env instead.

According to the documentation: "The SSH session created by Heroku Exec will not have the config vars set as environment variables (i.e., env in a session will not list config vars set by heroku config:set)."
