Connect to external redis

While the Redis service in the demo is deployed within a Kubernetes cluster, it’s possible to use Aeraki Mesh to connect to a Redis service that’s outside of the cluster. This can be done by creating a service without selectors, followed by creating an EndpointSlice for the service to specify the address of the external Redis. Once that’s done, RedisService and Redis Destination can be used to manage traffic for the service, just as they would for Redis within the cluster.

kubectl apply -f- <<EOF
