<p>I’m working to install prometheus operator, I took the default helm chart and install it via the following command:</p>

<pre><code>helm install po stable/prometheus-operator -n mon -f values.yaml
</code></pre>

<p>using <a href="https://github.com/helm/charts/tree/master/stable/prometheus-operator" rel="nofollow noreferrer">this</a> chart.</p>

<p>The installation was successful however it didn’t take the values from the <code>values.yaml</code> files, what am I doing wrong? e.g we don’t see two replicas of alert manger (minimal reproducible) </p>

<p>cat values.yaml</p>

<pre><code>prometheus-operator:
  defaultRules:
  grafana:
    enabled: true
  alertmanager:
    alertmanagerSpec:
      replicas: 2
</code></pre>

<p>the values yaml is on the folder which I execute the command. I'm using Helm 3</p>

<p>fairly certain it should look like this:</p>

<pre><code>grafana:
  enabled: true
alertmanager:
  enabled: true
  alertmanagerSpec:
    replicas: 2
</code></pre>
