<p>When I using helm v3.2.1 to install RabbitMQ HA in kubernetes v1.15.2 cluster follow by <a href="https://github.com/helm/charts/tree/master/stable/rabbitmq-ha" rel="nofollow noreferrer">this manual</a>:</p>

<pre><code>./helm install stable/rabbitmq-ha --generate-name -n dabai-pro
</code></pre>

<p>it give me this tips:</p>

<pre><code>[miao@MeowK8SMaster1 linux-amd64]$ ./helm install stable/rabbitmq-ha --generate-name -n dabai-pro
Error: unable to build kubernetes objects from release manifest: unable to recognize "": no matches for kind "PrometheusRule" in version "monitoring.coreos.com/v1"
</code></pre>

<p>should I install some dependencies? what should I do to make it work? This is my helm version detail info:</p>

<pre><code>[miao@MeowK8SMaster1 linux-amd64]$ ./helm version
version.BuildInfo{Version:"v3.2.1", GitCommit:"fe51cd1e31e6a202cba7dead9552a6d418ded79a", GitTreeState:"clean", GoVersion:"go1.13.10"}
</code></pre>

<p>and this is the repo I am using now:</p>

<pre><code>[miao@MeowK8SMaster1 linux-amd64]$ ./helm repo list
NAME    URL
stable  https://kubernetes-charts.storage.googleapis.com/
</code></pre>

<p>You can install <a href="https://github.com/coreos/prometheus-operator" rel="nofollow noreferrer">Prometheus operator</a> in the cluster. RabbitMQ is monitored by Prometheus.After installation verify by running below command</p>

<pre><code>kubectl api-resources | grep prom
prometheuses                                   monitoring.coreos.com          true         Prometheus
prometheusrules                                monitoring.coreos.com          true         PrometheusRule
</code></pre>

<p>For different installation options(including helm) of Prometheus check <a href="https://github.com/coreos/prometheus-operator#prometheus-operator-vs-kube-prometheus-vs-community-helm-chart" rel="nofollow noreferrer">this</a></p>
