Edit the Security group and assign the one we created for redis earlier.

Hit create and we’re done. It will take few minutes for AWS to create this redis cache for us. In the meantime, we login into our bastian instance and prepare few things to test our redis cache for sidekiq.

Connect to the bastian instance. Please refer to Create Bastian instance to test or troubleshoot Rails, RDS and Redis article section Connect to the Bastian instance

Once you have made the connection, do the following:

Now you need to endpoint of your Redis cache, Go to Your AWS Elastic Cache and click on your redis cache. Copy the endpoint from there.

From your bastian terminal, run the following command:
