<p>I have described helm template for redis&quot;</p>

<p>When I try to connect to redis with the password I get error <code>'Warning: AUTH failed'</code> if I connect without password - <code>connection successful</code>. I don't know why the password doesn't work when I use :</p>
<pre class="lang-yaml prettyprint-override"><code>env:
   - name: REDIS_PASSWORD
     value: &quot;9dtjger&quot;
</code></pre>
<p>In docker-compose locally I cannot connect without a password.</p>
<p>How can I set a password for Redis in Kubernetes?</p>

Роман
<p>You didn't specify how you installed Redis❓ (Which Helm Chart). Essentially adding the <code>--requirepass ${REDIS_PASSWORD}&quot;</code> and <code>--masterauth ${REDIS_PASSWORD}&quot;</code> should do 👌.</p>
<p>If for example, you used the Bitnami Helm chart, you can use the <a href="https://github.com/bitnami/charts/tree/master/bitnami/redis#parameters" rel="nofollow noreferrer"><code>usePassword</code></a> parameter. Then in the template, it gets used <a href="https://github.com/bitnami/charts/blob/master/bitnami/redis/templates/redis-master-statefulset.yaml#L106" rel="nofollow noreferrer">here</a>.</p>
