I’ve just ‘launched’ a Rails app and it worked (almost) 100% seamlessly!
However, I get an exception and the logs say Redis::CannotConnectError.
I’ve used the configuration via flyctl launch setting redis to true.
What could be wrong?
Turns out REDIS_URL wasn’t set. Would be great if it did that automatically on the first launch?
Run these commands:
flyctl redis list or flyctl redis create if none exist
flyctl redis status <name>
copy private URL
flyctl secrets set REDIS_URL=<paste private url>
