I need to access google cloud memorystore from cloud function but i know it's not supported yet, so i tried workaround to add haproxy in my kubernetes cluster and make it publicly access able using kubernetes service from type loadbalancer and forward the tcp requests to memorystore.

It works fine with me and i can connect to my memorystore instance from cloud function, but only the problem i have and i need fix for it to securing memorystore on the haproxy level or on the memorystore level, i tried to add a password to memorystore but i found the CONFIG command is disabled.

That's my haproxy config:

frontend redis_frontend
   bind *:6379
   mode tcp
   option tcplog
   timeout client  1m
   default_backend redis_backend

backend redis_backend
   mode tcp
   option tcplog
   option log-health-checks
   option redispatch
   log global
   balance roundrobin
   timeout connect 10s
   timeout server 1m
   server redis_server 10.0.0.12:6379 check

So any suggestions ?
