<p>When trying to install &quot;rabbitmq-ha&quot; I have an error:</p>
<pre><code>$ helm install rabbitmq stable/rabbitmq-ha
Error: unable to build kubernetes objects from release manifest: unable to recognize &quot;&quot;: no matches for kind &quot;PrometheusRule&quot; in version &quot;monitoring.coreos.com/v1&quot;
</code></pre>
<p>Version of Helm and Kubernetes:</p>
<ul>
<li>Version of Helm : &quot;v3.2.1&quot;</li>
<li>Version of Kubernetes : &quot;v1.17.5-0&quot;</li>
</ul>

<p>I solved the problem by using this command to install RabbitMQ:</p>
<pre><code>helm install --set replicaCount=2 \
               --set rabbitmqUsername=yourUSERNAME \
               --set rabbitmqPassword=yourPASSWORD \
               --set prometheus.operator.enabled=false \
               ha-rabbitmq stable/rabbitmq-ha
</code></pre>
<p>but I opened the <a href="https://github.com/helm/charts/issues/22346" rel="nofollow noreferrer">issue</a> on Github for helm-chart and a contributor on the project  <a href="https://github.com/helm/charts/issues/22346#issuecomment-628280070" rel="nofollow noreferrer">say</a>:</p>
<blockquote>
<p>Confirming the bug too. This is caused by the following PR: #21274
(comment)</p>
<p>The regression was released in rabbitmq-ha chart version 1.44.2.
1.44.1 works OK.</p>
