I used the sentinel to connect, is the pod IP. Also, how to use get_master method. my Code is local rc = require("resty.redis.connector").new(redis)

local redis, err = rc:connect{ url = "sentinel://mymaster:a/2", sentinels = { { host = "10.62.108.88", port = 32641 }, } } if not redis then
ngx.say("close redis error : ", err)
end

local master, err = require("resty.redis.sentinel").get_master(sentinels, master_name) if not master then
ngx.say("close redis error : ", err) end

I already changed the sentinels in the default table. like: sentinels = { { host = "10.62.108.88", port = 32641 }, } the Output is

my goal is use nignx can find the master redis and only be the proxy for that. my plan is find the master's IP by sentinel, and set the IP as a parameter that I can use that in stream to proxy_pass. Can this module achieve it? thanks!
