It is possible to install Istio using only kubectl, using the new Customization available in kubectl 1.14+. This uses the Kustomize style declarative customization and patching.

Simplest install of a demo profile requires 2 commands, first to install the cluster-wide configs (CRDs, cluster roles, namespaces) and the second to install the actual Istio deployments in istio-system namespace:

  kubectl apply -k github.com/istio/installer/kustomize/cluster
  kubectl apply -k github.com/istio/installer/test/demo

To uninstall:

  kubectl delete ns istio-system
  kubectl delete ValidatingWebhookConfiguration  istio-galley
  kubectl delete MutatingWebhookConfiguration istio-sidecar-injector

The demo install enables most Istio components and uses low cpu requests, it is suitable to try out Istio features and testing, but not for production workloads or traffic.
