<p>Hey trying to install jenkins on GKE cluster with this command </p>

<p><code>helm install stable/jenkins -f test_values.yaml --name myjenkins</code> </p>

<p>My version of helm and kubectl if matters</p>

<pre><code>helm version
Client: &amp;version.Version{SemVer:"v2.13.0", GitCommit:"79d07943b03aea2b76c12644b4b54733bc5958d6", GitTreeState:"clean"}
Server: &amp;version.Version{SemVer:"v2.13.0", GitCommit:"79d07943b03aea2b76c12644b4b54733bc5958d6", GitTreeState:"clean"}
</code></pre>

<pre><code>kubectl version
Client Version: version.Info{Major:"1", Minor:"17", GitVersion:"v1.17.0", GitCommit:"70132b0f130acc0bed193d9ba59dd186f0e634cf", GitTreeState:"clean", BuildDate:"2019-12-13T11:51:44Z", GoVersion:"go1.13.4", Compiler:"gc", Platform:"darwin/amd64"}
Server Version: version.Info{Major:"1", Minor:"13+", GitVersion:"v1.13.11-gke.14", GitCommit:"56d89863d1033f9668ddd6e1c1aea81cd846ef88", GitTreeState:"clean", BuildDate:"2019-11-07T19:12:22Z", GoVersion:"go1.12.11b4", Compiler:"gc", Platform:"linux/amd64"}
</code></pre>

<p>Values downloaded with this command <code>helm inspect values stable/jenkins &gt; test_values.yaml</code> and modified:</p>

<pre><code>cat test_values.yaml
Master:
  adminPassword: 34LbGfq5LWEUgw // local testing
  resources:
    limits:
      cpu: '500m'
      memory: '1024'
  podLabels:
    nodePort: 32323
  serviceType: ClusterIp

Persistence:
  storageClass: 'managed-nfs-storage'
  size: 5Gi

rbac:
  create: true
</code></pre>

<p>and some weird new error after update</p>

<pre><code>$ helm install stable/jekins --name myjenkins -f test_values.yaml
Error: failed to download "stable/jekins" (hint: running `helm repo update` may help)
$ helm repo update
Hang tight while we grab the latest from your chart repositories...

</code></pre>

<p>As I can see you're trying to install <code>stable/jekins</code> which isn't in the helm repo instead of <code>stable/je</code><strong>n</strong><code>kins</code>. Please update your question if it's just misspelling and I'll update my answer , but I've tried your command:</p>

<pre><code>$helm install stable/jekins --name myjenkins -f test_values.yaml
</code></pre>

<p>and got the same error:</p>

<pre><code>Error: failed to download "stable/jekins" (hint: running `helm repo update` may help)
</code></pre>

<p><strong>EDIT</strong> To solve next errors like:</p>

<pre><code>Error: render error in "jenkins/templates/deprecation.yaml": template: jenkins/templates/deprecation.yaml:258:11: executing "jenkins/templates/deprecation.yaml" at &lt;fail "Master.* values have been renamed, please check the documentation"&gt;: error calling fail: Master.* values have been renamed, please check the documentation
</code></pre>

<p>and </p>

<pre><code>Error: render error in "jenkins/templates/deprecation.yaml": template: jenkins/templates/deprecation.yaml:354:10: executing "jenkins/templates/deprecation.yaml" at &lt;fail "Persistence.* values have been renamed, please check the documentation"&gt;: error calling fail: Persistence.* values have been renamed, please check the documentation
</code></pre>

<p>and so on you also need to edit <code>test_values.yaml</code></p>

<pre><code>master:
  adminPassword: 34LbGfq5LWEUgw
  resources:
    limits:
      cpu: 500m
      memory: 1Gi
  podLabels:
    nodePort: 32323
  serviceType: ClusterIP

persistence:
  storageClass: 'managed-nfs-storage'
  size: 5Gi

rbac:
  create: true
</code></pre>

<p>And after that it's deployed successfully:</p>

<pre><code>$helm install stable/jenkins --name myjenkins -f test_values.yaml

NOTES:
1. Get your 'admin' user password by running:
  printf $(kubectl get secret --namespace default myjenkins -o jsonpath="{.data.jenkins-admin-password}" | base64 --decode);echo
2. Get the Jenkins URL to visit by running these commands in the same shell:
  export POD_NAME=$(kubectl get pods --namespace default -l "app.kubernetes.io/component=jenkins-master" -l "app.kubernetes.io/instance=myjenkins" -o jsonpath="{.items[0].metadata.name}")
  echo http://127.0.0.1:8080
  kubectl --namespace default port-forward $POD_NAME 8080:8080

3. Login with the password from step 1 and the username: admin
