Istio Setup

Istio

Istio is a power traffic mesh management tool. It also provides an ingress gateway for the Kubernetes cluster.

Installation

Operator Setup

  • The following setup can be done from the client machine. This installs Istio Operator, Istio Service Mesh, Istio Ingressgateway components.

  • From kubernetes/istio directory, run;

    istioctl operator init
kubectl apply -f istio-operator.yaml
    • Wait for istiod and ingressgateway pods to start.

  • Or, for Rancher cluster, run:

    kubectl apply -f istio-ef-spdy-upgrade.yaml

Namespace Setup

Set up an Istio gateway on each namespace for a domain. This assumes that the namespace (and relevant Rancher project) are already created (you may use the Rancher console to create a namespace or via command line kubectl)

  • Edit and run this to define the variables:

    export NS=dev
export WILDCARD_HOSTNAME='*.dev.your.org'

  • From kubernetes/istio directory, run the following:

    envsubst < istio-gateway.yaml | kubectl apply -f -
