Quick start instructions for the setup and configuration of Istio using Helm.
This is the recommended install method for installing Istio to your
production environment as it offers rich customization to the Istio control
plane and the sidecars for the Istio data plane.

## Prerequisites

1. [Download the Istio release](/docs/setup/kubernetes/download-release/).

1. [Kubernetes platform setup](/docs/setup/kubernetes/platform-setup/):
  * [Minikube](/docs/setup/kubernetes/platform-setup/minikube/)
  * [Google Container Engine (GKE)](/docs/setup/kubernetes/platform-setup/gke/)
  * [IBM Cloud Kubernetes Service (IKS)](/docs/setup/kubernetes/platform-setup/ibm/)
  * [OpenShift Origin](/docs/setup/kubernetes/platform-setup/openshift/)
  * [Amazon Web Services (AWS) with Kops](/docs/setup/kubernetes/platform-setup/aws/)
  * [Azure](/docs/setup/kubernetes/platform-setup/azure/)
  * [Docker For Desktop](/docs/setup/kubernetes/platform-setup/docker-for-desktop/)

1. Check the [Requirements for Pods and Services](/docs/setup/kubernetes/spec-requirements/) on Pods and Services.

1. [Install the Helm client](https://docs.helm.sh/using_helm/).

1. Istio by default uses `LoadBalancer` service object types.  Some platforms do not support `LoadBalancer`
   service objects.  For platforms lacking `LoadBalancer` support, install Istio with `NodePort` support
   instead with the flags `--set gateways.istio-ingressgateway.type=NodePort --set gateways.istio-egressgateway.type=NodePort`
   appended to the end of the Helm operation.

## Installation steps

The following commands have relative references in the Istio directory. You must execute the commands in Istio's root directory.

1. If using a Helm version prior to 2.10.0, install Istio's [Custom Resource Definitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#customresourcedefinitions)
via `kubectl apply`, and wait a few seconds for the CRDs to be committed in the kube-apiserver:

    {{< text bash >}}
    $ kubectl apply -f install/kubernetes/helm/istio/templates/crds.yaml
    {{< /text >}}

    If you are enabling `certmanager`, you also need to install its CRDs as well and wait a few seconds for the CRDs to be committed in the kube-apiserver:

    {{< text bash >}}
    $ kubectl apply -f install/kubernetes/helm/subcharts/certmanager/templates/crds.yaml
    {{< /text >}}

1.  Update Helm's dependencies:

    {{< text bash >}}
    $ helm repo add istio.io "https://storage.googleapis.com/istio-prerelease/daily-build/master-latest-daily/charts"
    $ helm dep update install/kubernetes/helm/istio
    {{< /text >}}

1. Choose one of the following two
**mutually exclusive** options described below.

### Option 1: Install with Helm via `helm template`

1. Render Istio's core components to a Kubernetes manifest called `istio.yaml`:

    {{< text bash >}}
    $ helm template install/kubernetes/helm/istio --name istio --namespace istio-system > $HOME/istio.yaml
    {{< /text >}}

    If you want to enable [global mutual TLS](/docs/concepts/security/#mutual-tls-authentication), set `global.mtls.enabled` to `true`:

    {{< text bash >}}
    $ helm template install/kubernetes/helm/istio --name istio --namespace istio-system --set global.mtls.enabled=true > $HOME/istio.yaml
    {{< /text >}}

1. Install the components via the manifest:

    {{< text bash >}}
    $ kubectl create namespace istio-system
    $ kubectl apply -f $HOME/istio.yaml
    {{< /text >}}

### Option 2: Install with Helm and Tiller via `helm install`

This option allows Helm and
[Tiller](https://github.com/kubernetes/helm/blob/master/docs/architecture.md#components)
to manage the lifecycle of Istio.

1. If a service account has not already been installed for Tiller, install one:

    {{< text bash >}}
    $ kubectl apply -f install/kubernetes/helm/helm-service-account.yaml
    {{< /text >}}

1. Install Tiller on your cluster with the service account:

    {{< text bash >}}
    $ helm init --service-account tiller
    {{< /text >}}

1. Install Istio:

    {{< text bash >}}
    $ helm install install/kubernetes/helm/istio --name istio --namespace istio-system
    {{< /text >}}

    If you want to enable [global mutual TLS](/docs/concepts/security/#mutual-tls-authentication), set `global.mtls.enabled` to `true`:

    {{< text bash >}}
    $ helm install install/kubernetes/helm/istio --name istio --namespace istio-system --set global.mtls.enabled=true
    {{< /text >}}

## Uninstall

* For option 1, uninstall using `kubectl`:

    {{< text bash >}}
    $ kubectl delete -f $HOME/istio.yaml
    {{< /text >}}

* For option 2, uninstall using Helm:

    {{< text bash >}}
    $ helm delete --purge istio
    {{< /text >}}

    If your Helm version is less than 2.9.0, then you need to manually cleanup extra job resource before redeploy new version of Istio chart:

    {{< text bash >}}
    $ kubectl -n istio-system delete job --all
    {{< /text >}}

* If desired, delete the CRDs:

    {{< text bash >}}
    $ kubectl delete -f install/kubernetes/helm/istio/templates/crds.yaml
    {{< /text >}}
