Overview

This repository build a simple Hello container based on this repository but without the HTML template. It's used in this Medium article

The purpose is to return a simple string with all the important information. It's easier to handle with curl

The hello.yaml file allow to deploy the container on any Knative compliant cluster.

Container registry

The container is publicly accessible: gcr.io/cloudrun-hello-go/hello

Build

Build the container with the tool that you prefer

# Docker
docker build . -t <tag>

# Cloud Build
gcloud builds submit --tag <tag>

Deployment

On K8S cluster, perform this command

kubectl apply -f hello.yaml

Test

Perform the test of the Knative service on your cluster with this command

curl -H "Host: $(kubectl get route.serving.knative.dev hello-yaml \
   -o jsonpath='{.status.url}' | sed 's/http:\/\///g')" \
   $(kubectl get svc istio-ingressgateway --namespace istio-system \
   -o jsonpath='{.status.loadBalancer.ingress[0].ip}')

Be careful, ingress definition can change from cluster to another one. Try to change ip by hostname. This is the case for AWS EKS cluster
