Istio Helm Chart Instructions
Quick Start instructions for the setup and configuration of Istio using the Helm package manager.
Warning: Helm charts are currently broken in 0.5.0
Prerequisites
The following instructions require you have access to Helm 2.7.2 or newer in your Kubernetes environment or alternately the ability to modify RBAC rules required to install Helm. Additionally Kubernetes 1.7.3 or newer is also required. Finally this Helm chart does not yet implement automatic sidecar injection.
Deploy with Helm
- If a service account has not already been installed for Helm, please install one:
kubectl create -f install/kubernetes/helm/helm-service-account.yaml - Initialize Helm:
helm init --service-account tiller - Create the Helm chart:
helm install install/kubernetes/helm/istio --name istio
Customization with Helm
The Helm chart ships with reasonable defaults. There may be circumstances in which defaults require overrides. To override Helm values, use --set key=value argument during the helm install command. Multiple --set operations may be used in the same Helm operation.
Helm charts expose configuration options which are currently in alpha. The currently exposed options are explained in the following table:
