redis-sentinel-proxy

Small command utility that:

• Given a redis sentinel server listening on SENTINEL_PORT, keeps asking it for the address of a master named NAME

• Proxies all tcp requests that it receives on PORT to that master

Usage:

./redis-sentinel-proxy -listen IP:PORT -sentinel :SENTINEL_PORT -master NAME

Usage

1. Envioment variables or commandline arguments

Environment Variables	Description	Required	Default
LISTEN	IP and Port to bind the proxy to		:9999
SENTINEL	sentinel server and port to connect to, or list		:26379
MASTER	master group name		mymaster
USERNAME	username to authenticate with if using v6 acls		-
PASSWORD	password to authenticate with to sentinel		-
REDIS_PASSWORD	password to authenticate with to redis if different from sentinel		-
DEBUG	debug output		false
TIMEOUTMS	timeout for sentinel and master connections		2000
CHECKMS	poll time to check sentinel for master changes, set to 0 to disable checks		250
EVENTLISTENER	subscribe to master changes from sentinal		false

2. Running the proxy

Edit kubernetes/redis-sentinel-proxy-deployment.yaml:

vim kubernetes/redis-sentinel-proxy-deployment.yaml
...
        args:
          - "-master"
          - "primary"
          - "-sentinel"
          - "redis-sentinel.$(NAMESPACE):26379" # change this to the sentinel address

Create redis-sentinel-proxy-deployment that uses redis-sentinel-proxy:

kubectl apply -f kubernetes/redis-sentinel-proxy-deployment.yaml
deployment "redis-sentinel-proxy" configured

Check if deployment is running:

kubectl get pods
redis-sentinel-proxy-2064359825-s4n0k   1/1       Running   0          1d

Expose redis-sentinel-proxy-deployment:

kubectl apply -f kubernetes/redis-sentinel-proxy-service.yaml
