To get started, you can install the redis gem:

bundle add redis

Next, you can update the config/environments/production.rb file with this line:

config.cache_store = :redis_cache_store, { url: ENV["REDIS_URL"] }

After that, you can define the REDIS_URL environment variable. This example shows the format to use. Just replace <yourPassword> and <XXXXXX> with your own values:

REDIS_URL="rediss://default:<yourPassword>@<XXXXXX>.stackhero-network.com:6380"
