Step 1. I deployed redis without envoy sidecar. https://github.com/kubernetes/charts/tree/master/stable/redis
When running a regis-cli in another pod which does not have envoy, redis connection working ok. => Proved redis itself functions.
Step 2. Deployed a service in another pod which has envoy sidecar inject.
When trying to connect from the service to redis, the connection is not able to set up.
spec: destination: service: "*" ports: - port: 6379 protocol: redis
Does anyone have suggestions/ideas?
