{{< warning >}}
The Helm installation approach will be deprecated in the future.
We recommend [Installing with {{< istioctl >}}](/docs/setup/install/istioctl/), instead.
{{< /warning >}}

Follow this guide to install and configure an Istio mesh for in-depth evaluation or production use.

This installation guide uses [Helm](https://github.com/helm/helm) charts that provide rich
customization of the Istio control plane and of the sidecars for the Istio data plane.
You can simply use `helm template` to generate the configuration and then install it
using `kubectl apply`, or you can choose to use `helm install` and let
[Tiller](https://helm.sh/docs/topics/architecture/#components)
completely manage the installation.

Using these instructions, you can select any one of Istio's built-in
[configuration profiles](/docs/setup/additional-setup/config-profiles/)
and then further customize the configuration for your specific needs.

## Prerequisites

1. [Download the Istio release](/docs/setup/getting-started/#download).

1. Perform any necessary [platform-specific setup](/docs/setup/platform-setup/).

1. Check the [Requirements for Pods and Services](/docs/ops/deployment/requirements/).

1. [Install a Helm client](https://github.com/helm/helm#install) with a version higher than 2.10.

    {{< warning >}}
    Use a 2.x version of Helm. Helm 3 is not supported.
    {{< /warning >}}

## Helm chart release repositories

The commands in this guide use the Helm charts that are included in the Istio release image.
If you want to use the Istio release Helm chart repository instead, adjust the commands accordingly and
add the Istio release repository as follows:

{{< text bash >}}
$ helm repo add istio.io https://storage.googleapis.com/istio-release/releases/{{< istio_full_version >}}/charts/
{{< /text >}}

## Installation steps

Change directory to the root of the release and then
choose one of the following two **mutually exclusive** options:

1. To deploy Istio without using Tiller, follow the instructions for [option 1](/docs/setup/install/helm/#option-1-install-with-helm-via-helm-template).
1. To use [Helm's Tiller pod](https://helm.sh/) to manage your Istio release, follow the instructions for [option 2](/docs/setup/install/helm/#option-2-install-with-helm-and-tiller-via-helm-install).

{{< tip >}}
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`
appended to the end of the Helm instructions in the installation steps below.
{{< /tip >}}

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

Choose this option if your cluster doesn't have [Tiller](https://helm.sh/docs/topics/architecture/#components)
deployed and you don't want to install it.

1. Create a namespace for the `istio-system` components:

    {{< text bash >}}
    $ kubectl create namespace istio-system
    {{< /text >}}

1. Install all the Istio
    [Custom Resource Definitions](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#customresourcedefinitions)
    (CRDs) using `kubectl apply`:

    {{< text bash >}}
    $ helm template install/kubernetes/helm/istio-init --name istio-init --namespace istio-system | kubectl apply -f -
    {{< /text >}}

1. {{< boilerplate verify-crds >}}

1. Select a [configuration profile](/docs/setup/additional-setup/config-profiles/)
    and then render and apply Istio's core components corresponding to your chosen profile.
    The **default** profile is recommended for production deployments:

    {{< tip >}}
    You can further customize the configuration by adding one or more `--set <key>=<value>`
    [Installation Options](/docs/reference/config/installation-options/) to the helm command.
    {{< /tip >}}

{{< tabset category-name="helm_profile" >}}

{{< tab name="default" category-value="default" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="demo" category-value="demo" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-demo.yaml | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="minimal" category-value="minimal" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-minimal.yaml | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="sds" category-value="sds" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-sds-auth.yaml | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="Mutual TLS enabled" category-value="mtls" >}}

Enable mutual TLS in Istio by setting options `global.controlPlaneSecurityEnabled=true`
and `global.mtls.enabled=true`, in addition to the specifying the Helm values file
corresponding to your chosen profile.

For example, to configure the `demo` profile with mutual TLS enabled:

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-demo.yaml \
    --set global.controlPlaneSecurityEnabled=true \
    --set global.mtls.enabled=true | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="Istio CNI enabled" category-value="cni" >}}

Install the [Istio CNI](/docs/setup/additional-setup/cni/) components:

{{< text bash >}}
$ helm template install/kubernetes/helm/istio-cni --name=istio-cni --namespace=kube-system | kubectl apply -f -
{{< /text >}}

Enable CNI in Istio by setting `--set istio_cni.enabled=true` in addition to the settings for your chosen profile.
For example, to configure the **default** profile:

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --set istio_cni.enabled=true | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< /tabset >}}

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

This option allows Helm and
[Tiller](https://helm.sh/docs/topics/architecture/#components)
to manage the lifecycle of Istio.

{{< boilerplate helm-security-warning >}}

1. Make sure you have a service account with the `cluster-admin` role defined for Tiller.
   If not already defined, create one using following command:

    {{< 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 the `istio-init` chart to bootstrap all the Istio's CRDs:

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

1. {{< boilerplate verify-crds >}}

1. Select a [configuration profile](/docs/setup/additional-setup/config-profiles/)
    and then install the `istio` chart corresponding to your chosen profile.
    The **default** profile is recommended for production deployments:

    {{< tip >}}
    You can further customize the configuration by adding one or more `--set <key>=<value>`
    [Installation Options](/docs/reference/config/installation-options/) to the helm command.
    {{< /tip >}}

{{< tabset category-name="helm_profile" >}}

{{< tab name="default" category-value="default" >}}

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

{{< /tab >}}

{{< tab name="demo" category-value="demo" >}}

{{< text bash >}}
$ helm install install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-demo.yaml
{{< /text >}}

{{< /tab >}}

{{< tab name="minimal" category-value="minimal" >}}

{{< text bash >}}
$ helm install install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-minimal.yaml
{{< /text >}}

{{< /tab >}}

{{< tab name="sds" category-value="sds" >}}

{{< text bash >}}
$ helm install install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-sds-auth.yaml
{{< /text >}}

{{< /tab >}}

{{< tab name="Mutual TLS enabled" category-value="mtls" >}}

Enable mutual TLS in Istio by setting options `global.controlPlaneSecurityEnabled=true`
and `global.mtls.enabled=true`, in addition to the specifying the Helm values file
corresponding to your chosen profile.

For example, to configure the **demo** profile with mutual TLS enabled:

{{< text bash >}}
$ helm install install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-demo.yaml \
    --set global.controlPlaneSecurityEnabled=true \
    --set global.mtls.enabled=true | kubectl apply -f -
{{< /text >}}

{{< /tab >}}

{{< tab name="Istio CNI enabled" category-value="cni" >}}

Install the [Istio CNI](/docs/setup/additional-setup/cni/) chart:

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

Enable CNI in Istio by setting `--set istio_cni.enabled=true` in addition to the settings for your chosen profile.
For example, to configure the **default** profile:

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

{{< /tab >}}

{{< /tabset >}}

## Verifying the installation

1. Referring to components table in
    [configuration profiles](/docs/setup/additional-setup/config-profiles/),
    verify that the Kubernetes services corresponding to your selected profile have been deployed.

    {{< text bash >}}
    $ kubectl get svc -n istio-system
    {{< /text >}}

1. Ensure the corresponding Kubernetes pods are deployed and have a `STATUS` of `Running`:

    {{< text bash >}}
    $ kubectl get pods -n istio-system
    {{< /text >}}

## Uninstall

- If you installed Istio using the `helm template` command, uninstall with these commands:

{{< tabset category-name="helm_profile" >}}

{{< tab name="default" category-value="default" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system | kubectl delete -f -
$ kubectl delete namespace istio-system
{{< /text >}}

{{< /tab >}}

{{< tab name="demo" category-value="demo" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-demo.yaml | kubectl delete -f -
$ kubectl delete namespace istio-system
{{< /text >}}

{{< /tab >}}

{{< tab name="minimal" category-value="minimal" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-minimal.yaml | kubectl delete -f -
$ kubectl delete namespace istio-system
{{< /text >}}

{{< /tab >}}

{{< tab name="sds" category-value="sds" >}}

{{< text bash >}}
$ helm template install/kubernetes/helm/istio --name istio --namespace istio-system \
    --values install/kubernetes/helm/istio/values-istio-sds-auth.yaml | kubectl delete -f -
$ kubectl delete namespace istio-system
{{< /text >}}

{{< /tab >}}

{{< tab name="Mutual TLS enabled" category-value="mtls" >}}

Follow the instructions corresponding to your selected configuration profile.

{{< /tab >}}

{{< tab name="Istio CNI enabled" category-value="cni" >}}

Follow the instructions corresponding to your selected configuration profile
and then execute the following command to uninstall the CNI plug-in:

{{< text bash >}}
$ helm template install/kubernetes/helm/istio-cni --name=istio-cni --namespace=kube-system | kubectl delete -f -
{{< /text >}}

{{< /tab >}}

{{< /tabset >}}

- If you installed Istio using Helm and Tiller, uninstall with these commands:

    {{< text bash >}}
    $ helm delete --purge istio
    $ helm delete --purge istio-init
    $ helm delete --purge istio-cni
    $ kubectl delete namespace istio-system
    {{< /text >}}

## Deleting CRDs and Istio Configuration

Istio, by design, expects Istio's Custom Resources contained within CRDs to leak into the
Kubernetes environment. CRDs contain the runtime configuration set by the operator.
Because of this, we consider it better for operators to explicitly delete the runtime
configuration data rather than unexpectedly lose it.

{{< warning >}}
Deleting CRDs permanently deletes any configuration changes that you have made to Istio.
{{< /warning >}}

The `istio-init` chart contains all raw CRDs in the `istio-init/files` directory.
You can simply delete the CRDs using `kubectl`.
To permanently delete Istio's CRDs and the entire Istio configuration, run:

{{< text bash >}}
$ kubectl delete -f install/kubernetes/helm/istio-init/files
{{< /text >}}
