Install Istio on the Alibaba Cloud Kubernetes Container Service

Follow this flow to install and configure an Istio mesh in the Alibaba Cloud Kubernetes Container Service using the Application Catalog module.

This flow installs the current release version of Istio and deploys the Bookinfo sample application.

Prerequisites

  • You have an available Alibaba Cloud Kubernetes cluster. Otherwise, create a Kubernetes cluster quickly and easily in the Container Service console.

  • Ensure kubectl works fine for your Kubernetes cluster.

  • You can create a namespace to deploy Istio components. The following example creates the istio-system namespace:

$ kubectl create namespace istio-system
  • You installed a service account for Tiller. To install one if you haven't, run the following command:
Zip
$ kubectl create -f @install/kubernetes/helm/helm-service-account.yaml@
  • You installed Tiller on your cluster. To install Tiller with the service account if you haven't, run the following command:
$ helm init --service-account tiller

Deploy Istio via the Application Catalog
