## Overview
## Project Setup
- Install the [Google Cloud SDK](https://cloud.google.com/sdk)
- Create a [Google Cloud](https://console.cloud.google.com) project (with billing)
- Enable the following [APIs](https://console.cloud.google.com/apis/library):
- Cloud Build
- Container Registry
- Cloud Run
- Kubernetes Engine
```
gcloud services enable \
container.googleapis.com \
containerregistry.googleapis.com \
cloudbuild.googleapis.com \
run.googleapis.com
```
## Infrastructure Setup
- Create a GKE cluster
```
gcloud beta container clusters create workshop \
--addons=HorizontalPodAutoscaling,HttpLoadBalancing \
--machine-type=n1-standard-4 \
--cluster-version=latest \
--enable-stackdriver-kubernetes \
--enable-ip-alias \
--scopes cloud-platform
```
- Grab the cluster credentials so you can run `kubectl` commands
`gcloud container clusters get-credentials workshop`
- Create a `cluster-admin` role binding so you can deploy and configure Istio and Knative
```
kubectl create clusterrolebinding cluster-admin-binding \
--clusterrole=cluster-admin \
--user=$(gcloud config get-value core/account)
```
### Install Istio
- Download and unpack Istio
`curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.5 sh -`
- Install the `demo` profile
`kubectl apply -f istio-1.2.5/install/kubernetes/istio-demo.yaml`
- Install Stackdriver support
`kubectl apply -f https://github.com/GoogleCloudPlatform/istio-samples/raw/master/stackdriver-metrics/istio-stackdriver-metrics.yaml`
- Configure Istio sidecar auto-injection in the `default` namespace
`kubectl label ns default istio-injection=enabled`
### Install Knative
- Install the Knative container resource definitions (CRDs)
```
kubectl apply --selector knative.dev/crd-install=true \
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml \
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml \
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml
```
- Install the Knative `serving`, `eventing`, and `monitoring` components
```
kubectl apply \
-f https://github.com/knative/serving/releases/download/v0.8.0/serving.yaml \
-f https://github.com/knative/eventing/releases/download/v0.8.0/release.yaml \
-f https://github.com/knative/serving/releases/download/v0.8.0/monitoring.yaml
```
- Find the `istio-ingressgateway` external IP address
```
INGRESS=$(kubectl get svc -n istio-system istio-ingressgateway -o jsonpath={.status.loadBalancer.ingress..ip})
```
- Update the internal Knative domain configuration with the IP address from the previous step, using [xip.io](http://xip.io) as the dynamic DNS provider
- **Note**: this is for demo purposes only. For production deployments, refer to [Setting up a custom domain](https://knative.dev/docs/serving/using-a-custom-domain/) for Knative on GKE
```
kubectl patch configmap config-domain --namespace knative-serving --patch \
'{"data": {"example.com": null, "[INGRESS].xip.io": ""}}'
```
## Deploying Examples
- Install [Hipstershop](https://github.com/GoogleCloudPlatform/microservices-demo)
```
kubectl apply -f hipstershop-istio.yaml
kubectl apply -f hipstershop-kubernetes.yaml
```
- Install the [Office Space](http://github.com/crcsmnky/cloud-run-office-space) sample app
`kubectl apply -f officespace-knative.yaml`
## Usage
- Check out monitoring, logging, and tracing using Istio and Stackdriver ([link](https://github.com/GoogleCloudPlatform/istio-samples/tree/master/istio-stackdriver/))
- Generate transactions, check bank holdings, and check the account balance using the Office Space app ([link](https://github.com/crcsmnky/cloud-run-office-space#usage))
## Cleanup
`gcloud container clusters delete workshop`
