<p>Hi everyone,</p>

<p>I have deployed a Kubernetes cluster based on kubeadm and for the purpose of performing HorizontalPodAutoscaling based on the Custom Metrics, I have deployed prometheus-adpater through Helm.</p>

<p>Now, i want to edit the configuration for prometheus-adpater and because i am new to Helm, i don't know how to do this. So could you guid me how to edit the deployed helm charts?</p>

<p>I guess <a href="https://helm.sh/docs/helm/#helm-upgrade" rel="noreferrer">helm upgrade</a> is that are you looking for.</p>

<blockquote>
  <p>This command upgrades a release to a specified version of a chart and/or updates chart values.</p>
</blockquote>

<p>So if you have deployed prometheus-adapter, you can use command <a href="https://helm.sh/docs/helm/#helm-fetch" rel="noreferrer">helm fetch</a> </p>

<blockquote>
  <p>Download a chart from a repository and (optionally) unpack it in local directory</p>
</blockquote>

<p>You will have all yamls, you can edit them and upgrade your current deployed chart via helm upgrade</p>

<p>I found an <a href="https://dzone.com/articles/create-install-upgrade-rollback-a-helm-chart-part" rel="noreferrer">example</a>, which should explain it to you more precisely. </p>
