Install istio from code on minikube.

From base directory, run:

go run istioctl/cmd/istioctl/main.go install

Install examples

From the base directory, follow booksinfo https://istio.io/latest/docs/examples/bookinfo/

Follow all step thru Gateway and access the product page on browser:

minikube service productpage

and replace the browser URL with

http://Host:NodePort/productpage

Build and Debug [Workaround approach]

From Istio base directory, create this mkdir -p ./out/linux_amd64/docker_build/docker.pilot/

a). Add this in pilot/docker/Dockerfile.pilot

#ENTRYPOINT ["/usr/local/bin/pilot-discovery"]

EXPOSE 40000
COPY ./dlv/dlv /usr/local/bin/dlv
ENTRYPOINT ["/usr/local/bin/dlv", "--listen=:40000", "--headless=true", "--api-version=2", "exec", "/usr/local/bin/pilot-discovery", "--"]

b). Copy dlv in ./out/linux_amd64/docker_build/docker.pilot/

1. Build pilot

sudo GOOS=linux DEBUG=1 make docker.pilot

2. Export istio/pilot image to tar if we using local machine Docker daemon. Grab the image id.

docker save <IMG ID> -o istio_pilot.tar

3. ssh to minikube

minikube ssh

or switch minikube daemon

eval $(minikube docker-env)

4. Import the image into minikube Docker

docker load -i istio_pilot.tar

5. Tag the newly import image docker tag my-local/istio_pilot:latest

6. Change IstioD deployment. Update image, pullPolicy and expose DEBUG Port

   image: <IMAGE>
   imagePullPolicy: Never
   ....
       - containerPort: 40000
         protocol: TCP  
```yaml         

You might have tweak securityContext for dlv. Change this in IstioD deploymet:
```yaml
      securityContext:
            capabilities:
              drop:
                - ALL
            runAsUser: 1337
            runAsGroup: 1337
            runAsNonRoot: true
            readOnlyRootFilesystem: false
            allowPrivilegeEscalation: true         

7. Setup istioD port forwarding from 40000.

8. Add Intellij remote debug from host:localhost and port 40000
