-# Ambassador
-
-Ambassador is an open source, Kubernetes-native [microservices API gateway](https://www.getambassador.io/about/microservices-api-gateways) built on the [Envoy Proxy](https://www.envoyproxy.io/). 
-
-## TL;DR;
-
-```console
-$ helm install stable/ambassador
-```
-
-## Introduction
-
-This chart bootstraps an [Ambassador](https://www.getambassador.io) deployment on 
-a [Kubernetes](http://kubernetes.io) cluster using the [Helm](https://helm.sh) package manager.
-
-## Prerequisites
-
-- Kubernetes 1.7+
-
-## Installing the Chart
-
-To install the chart with the release name `my-release`:
-
-```console
-$ helm install --name my-release stable/ambassador
-```
-
-The command deploys Ambassador API gateway on the Kubernetes cluster in the default configuration. 
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `my-release` deployment:
-
-```console
-$ helm delete --purge my-release
-```
-
-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 Ambassador chart and their default values.
-
-| Parameter                       | Description                                | Default                                                    |
-| ------------------------------- | ------------------------------------------ | ---------------------------------------------------------- |
-| `image` | Image | `quay.io/datawire/ambassador` 
-| `imageTag` | Image tag | `0.29.0` 
-| `imagePullPolicy` | Image pull policy | `IfNotPresent` 
-| `replicaCount`  | Number of Ambassador replicas  | `1` 
-| `resources` | CPU/memory resource requests/limits | None 
-| `rbac.create` | If `true`, create and use RBAC resources | `true`
-| `serviceAccount.create` | If `true`, create a new service account | `true`
-| `serviceAccount.name` | Service account to be used | `ambassador`
-| `service.type` | Service type to be used | `LoadBalancer`
-| `adminService.create` | If `true`, create a service for Ambassador's admin UI | `true`
-| `adminService.type` | Ambassador's admin service type to be used | `ClusterIP`
-| `exporter.image` | Prometheus exporter image | `datawire/prom-statsd-exporter:0.6.0`
-| `timing.restart` | The minimum number of seconds between Envoy restarts | `15`
-| `timing.drain` | The number of seconds that the Envoy will wait for open connections to drain on a restart | `5`
-| `timing.shutdown` | The number of seconds that Ambassador will wait for the old Envoy to clean up and exit on a restart | `10`

-# Weave Cloud Grafana
-
-Grafana v5 with Kubernetes dashboards and Prometheus and Weave Cloud data sources.
-
-## Installing the Chart
-
-To install the chart with the release name `my-release`:
-
-```console
-$ helm install stable/grafana --name my-release \
-    --set service.type=NodePort \
-    --set token=WEAVE-TOKEN \
-    --set password=admin
-```
-
-The command deploys Grafana on the Kubernetes cluster in the default namespace.
-The [configuration](#configuration) section lists the parameters that can be configured during installation.
-
-## Uninstalling the Chart
-
-To uninstall/delete the `my-release` deployment:
-
-```console
-$ helm delete --purge my-release
-```
-
-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 Grafana chart and their default values.
-
-Parameter | Description | Default
---- | --- | ---
-`image.repository` | Image repository | `grafana/grafana`
-`image.pullPolicy` | Image pull policy | `IfNotPresent`
-`image.tag` | Image tag | `5.0.1`
-`replicaCount` | desired number of pods | `1`
-`resources` | pod resources | `none`
-`tolerations` | List of node taints to tolerate | `[]`
-`affinity` | node/pod affinities | `node`
-`nodeSelector` | node labels for pod assignment | `{}`
-`service.type` | type of service | `LoadBalancer`
-`url` | Prometheus URL, used when Weave token is empty | `http://prometheus:9090`
-`token` | Weave Cloud token | `none`
-`user` | Grafana admin username | `admin`
-`password` | Grafana admin password | `none`
-
-Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
-
-```console
-$ helm install stable/grafana --name my-release \
-  --set=token=WEAVE-TOKEN \
-  --set password=admin
-```
-
-Alternatively, a YAML file that specifies the values for the above parameters can be provided while installing the chart. For example,
-
-```console
-$ helm install stable/grafana --name my-release -f values.yaml
-```
-
-> **Tip**: You can use the default [values.yaml](values.yaml)
-```

-# Podinfo Istio
-
-Podinfo is a tiny web application made with Go 
-that showcases best practices of running microservices in Kubernetes.
-
-## Installing the Chart
-
-Create an Istio enabled namespace:
-
-```console
-kubectl create namespace demo
-kubectl label namespace demo istio-injection=enabled
-```
-
-Create an Istio Gateway in the `istio-system` namespace named `public-gateway`:
-
-```yaml
-apiVersion: networking.istio.io/v1alpha3
-kind: Gateway
-metadata:
-  name: public-gateway
-  namespace: istio-system
-spec:
-  selector:
-    istio: ingressgateway
-  servers:
-  - port:
-      number: 80
-      name: http
-      protocol: HTTP
-    hosts:
-    - "*"
-    tls:
-      httpsRedirect: true
-  - port:
-      number: 443
-      name: https
-      protocol: HTTPS
-    hosts:
-    - "*"
-    tls:
-      mode: SIMPLE
-      privateKey: /etc/istio/ingressgateway-certs/tls.key
-      serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
-```
-
-Create the `frontend` release by specifying the external domain name:
-
-```console
-helm upgrade frontend --install ./charts/podinfo-istio \
-  --namespace=demo \
-  --set host=podinfo.example.com \
-  --set gateway.name=public-gateway \
-  --set gateway.create=false \
-  -f ./charts/podinfo-istio/frontend.yaml
-```
-
-Create the `backend` release:
-
-```console
-helm upgrade backend --install ./charts/podinfo-istio \
-  --namespace=demo \
-  -f ./charts/podinfo-istio/backend.yaml 
-```
-
-Create the `store` release:
-
-```console
-helm upgrade store --install ./charts/podinfo-istio \
-  --namespace=demo \
-  -f ./charts/podinfo-istio/store.yaml 
-```
-
-Start load test:
