Deploy Istio in Kubernetes

To deploy Istio in Kubernetes, follow these step-by-step instructions:

1. Set Up a Kubernetes Cluster:
   • Create a Kubernetes cluster with Istio installed and define a namespace for the tutorial:

     export NAMESPACE=tutorial
     kubectl create namespace $NAMESPACE
     

2. Install Istio:
   • Install Istio using the demoprofile and include Kiali and Prometheus addons:

     kubectl apply -f @samples/addons@
     

3. Create Kubernetes Ingress Resource:
   • Define an Ingress resource for common Istio services like Grafana, tracing, Prometheus, and Kiali:

     kubectl apply -f - <<EOF
     apiVersion: networking.k8s.io/v1
     kind: Ingress
     metadata:
       name: istio-system
       namespace: istio-system
       annotations:
         kubernetes.io/ingress.class: istio
     spec:
       rules:
         - host: my-istio-dashboard.io
           http:
             paths:
               - path: /
                 pathType: Prefix
                 backend:
                   service:
                     name: grafana
                     port:
                       number: 3000
         # Add similar rules for other services like tracing, prometheus, and kiali
     EOF
     

4. Create Role for Namespace Access:
   • Create a role to provide read access to the istio-system namespace for participants.
5. Generate Kubernetes Configuration File:
   • Generate a Kubernetes configuration file for each participant using their own configuration details.
6. Set KUBECONFIG Environment Variable:
   • Set the KUBECONFIG environment variable to point to the generated configuration file.

By following these steps, you can deploy Istio in your Kubernetes cluster with necessary configurations and access controls in place.
