<p>I am trying to apply ISTIO rate limiting using Redis Handler using <a href="https://raw.githubusercontent.com/istio/istio/release-1.1/samples/bookinfo/policy/mixer-rule-productpage-redis-quota-rolling-window.yaml" rel="nofollow noreferrer">Redis Handler ISTIO</a></p>
<p>But mixer is not able to find the redis handler. Below from mixer log:</p>
<blockquote>
<p>2019-05-27T11:59:23.910183Z   warn    Unable to find a handler for action. rule[action]='quota.rule.istio-system[0]', handler='redishandler.istio-system'</p>
<ul>
<li>redisquota: could not create a connection to redis server: NOAUTH Authentication required.''.
Also, how to provide Redis credential for the template?</li>
</ul>
</blockquote>

Forkmohit
<p>redis quota does not support Authentication</p>

<pre class="lang-golang prettyprint-override"><code>    // test redis connection
    option := redis.Options{
        Addr: b.adapterConfig.RedisServerUrl,
    }

    if b.adapterConfig.ConnectionPoolSize &gt; 0 {
        option.PoolSize = int(b.adapterConfig.ConnectionPoolSize)
    }

</code></pre>
