+# Chronograf
+
+##  An Open-Source Time Series Database
+
+[Chronograf](https://github.com/influxdata/chronograf) is an open-source web application built by the folks over at [InfluxData](https://influxdata.com) and written in Go and React.js that provides the tools to visualize your monitoring data and easily create alerting and automation rules.
+
+## QuickStart
+
+```bash
+$ helm install stable/chronograf --name foo --namespace bar
+```
+
+## Introduction
+
+This chart bootstraps A Chronograf deployment and service on a Kubernetes cluster using the Helm Package manager.
+
+## Prerequisites
+
+- Kubernetes 1.4+
+- PV provisioner support in the underlying infrastructure (optional)
+
+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install --name my-release stable/chronograf
+```
+
+The command deploys Chronograf on the Kubernetes cluster in the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+> **Tip**: List all releases using `helm list`
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```bash
+$ helm delete my-release --purge
+```
+
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following tables lists the configurable parameters of the Chronograf chart and 
+their default values.
+
+```yaml
+image.repository: "quay.io/influxdb/chronograf"
+image.tag: "latest"
+image.pullPolicy: "Always"
+service.type: LoadBalancer
+persistence.enabled: false
+persistence.storageClass: generic
+persistence.accessMode: ReadWriteOnce
+persistence.size: 8Gi
+resources.requests.memory: 256Mi
+resources.requests.cpu: 0.1
+resources.limits.memory: 2Gi
+resources.limits.cpu: 2
+
+# Use this ingress with service.type: NodePort
+ingress.enabled: false
+ingress.tls: false
+ingress.hostname: chronograf.foobar.com
+ingress.annotations:
+ingress.annotations.kubernetes.io/ingress.class: "nginx"
+```
+
+The [full image documentation](https://quay.io/influxdb/chronograf) contains more information about running Chronograf in docker.
+
+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install --name my-release \
+  --set ingress.enabled=true,ingress.hostname=chronograf.foobar.com \
+    stable/chronograf
+```
+
+The above command enables persistence and changes the size of the requested data volume to 200GB.
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```bash
+$ helm install --name my-release -f values.yaml stable/chronograf
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
+
+## Persistence
+
+The [Chronograf](https://quay.io/influxdb/chronograf) image stores data in the `/var/lib/chronograf` directory in the container.
+
+The chart optionally mounts a [Persistent Volume](kubernetes.io/docs/user-guide/persistent-volumes/) volume at this location. The volume is created using dynamic volume provisioning.

-1. Get the application URL by running these commands:
-{{- if contains "NodePort" .Values.service.type }}
-  export NODE_PORT=$(kubectl get --namespace {{ .Release.Namespace }} -o jsonpath="{.spec.ports[0].nodePort}" services {{ template "fullname" . }})
-  export NODE_IP=$(kubectl get nodes --namespace {{ .Release.Namespace }} -o jsonpath="{.items[0].status.addresses[0].address}")
-  echo http://$NODE_IP:$NODE_PORT/login
-{{- else if contains "LoadBalancer" .Values.service.type }}
-     NOTE: It may take a few minutes for the LoadBalancer IP to be available.
-      You can watch the status of by running: 
-      
-      'kubectl get svc -w --namespace {{ .Release.Namespace }} {{ template "fullname" . }}'
-  export SERVICE_IP=$(kubectl get svc --namespace {{ .Release.Namespace }} {{ template "fullname" . }} -o jsonpath='{.status.loadBalancer.ingress[0].ip}')
-  echo http://$SERVICE_IP:{{ .Values.service.externalPort }}
-{{- else if contains "ClusterIP"  .Values.service.type }}
-  export POD_NAME=$(kubectl get pods --namespace {{ .Release.Namespace }} -l "app={{ template "fullname" . }}" -o jsonpath="{.items[0].metadata.name}")
-  echo "Visit http://127.0.0.1:8080 to use your application"
-  kubectl port-forward $POD_NAME 8080:{{ .Values.service.externalPort }}
+Chronograf can be accessed via port 80 on the following DNS name from within your cluster:
+
+- http://{{ template "fullname" . }}.{{ .Release.Namespace }}
+
+You can easily connect to the remote instance from your browser. Forward the webserver port to localhost:8888
+
+- kubectl port-forward --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{ .items[0].metadata.name }') 8888:80
+
+You can also connect to the container running Chronograf. To open a shell session in the pod run the following:
+
+- kubectl exec -i -t --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{.items[0].metadata.name}') /bin/sh
+
+To trail the logs for the Chronograf pod run the following:
+
+- kubectl logs -f --namespace {{ .Release.Namespace }} $(kubectl get pods --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }} -o jsonpath='{ .items[0].metadata.name }')
+
+{{- if eq .Values.service.type "LoadBalancer" }}
+
+To watch for the LoadBalancer IP run the following
+
+- kubectl get svc -w --namespace {{ .Release.Namespace }} -l app={{ template "fullname" . }}
 {{- end }}
+{{- if .Values.ingress.enabled }}
+
+Chronograf will be available at the following IP
+
+- http://{{ .Values.ingress.hostname }}
+{{- end -}}
