Unlike GKE that has a logging solution baked into a cluster, EKS requires us to set up a solution. It does provide CloudWatch service, but we need to ensure that the logs are shipped there from our cluster.
Just as before, we'll use Fluentd to collect logs and ship them to CloudWatch. Or, to be more precise, we'll use a Fluentd tag built specifically for CloudWatch. As you probably already know, we'll also need an IAM policy that will allow Fluentd to communicate with CloudWatch.
All in all, the setup we are about to make will be very similar to the one we did with Papertrail, except that we'll store the logs in CloudWatch, and that we'll have to put some effort into creating AWS permissions.
Before we proceed, I'll assume that you still have the environment variables AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY...
