The Heroku Redis CLI documentation states that connecting via the Heroku CLI is insecure, as it relies on the redis-cli binary.

Is there a secure way to connect to a Heroku Redis instance via a command-line interface? Connecting via my local machine, or though a dyno as a relay both work fine.

  • down vote I'm wondering about this as well. After installing the Stunnel buildpack, I didn't receive the insecure action warning anymore, but I'm not sure what this actually means. It's also not immediately clear how I verify that Stunnel is actually working as I don't have stunnel locally and thus have a flag in my procfile to invoke the stunnel binary based on an environment variable. Edit: Answered rather than commented, my bad. – kirps Apr 18 '16 at 22:08

I believe this is because you're using the hobby-dev tier of Heroku Redis which seems not to support SSL.

SSL for Heroku Redis is only available on production tier plans. The hobby-dev plan is meant for testing and staging environments, not production.
