-
-```yaml

-      privateKey: /etc/istio/ingressgateway-certs/tls.key
-      serverCertificate: /etc/istio/ingressgateway-certs/tls.crt
-```
-
-Find the gateway public IP:
-
-```bash
-IP=$(kubectl -n istio-system describe svc/istio-ingressgateway | grep 'Ingress' | awk '{print $NF}')
-```
-
-Create a zone in GCP Cloud DNS with the following records:
-
-```bash
-istio.example.com. A $IP
-*.istio.example.com. A $IP
-```
-
-Create a service account with Cloud DNS admin role (replace `my-gcp-project` with your project ID):
-
-```bash

---member=serviceAccount:dns-admin@${GCP_PROJECT}.iam.gserviceaccount.com \
---role=roles/dns.admin
-```
-
-Create a Kubernetes secret with the GCP Cloud DNS admin key:
-
-```bash
-kubectl create secret generic cert-manager-credentials \
---from-file=./gcp-dns-admin.json \
---namespace=istio-system

-    istio-injection: enabled
-  name: openfaas
----
-apiVersion: v1
-kind: Namespace

-
-Allow plaintext traffic to OpenFaaS Gateway:
-
-```yaml

-  name: permissive
-  namespace: openfaas
-spec:
-  targets:
-  - name: gateway

-
-Deny access to OpenFaaS core services from the `openfaas-fn` namespace except for system functions:
-
-```yaml

-  actions:
-  - handler: denyhandler.denier
-    instances: [ denyrequest.checknothing ]
-```
-
-### Install OpenFaaS
-
-Add the OpenFaaS `helm` chart:
-
-```bash
-$ helm repo add openfaas https://openfaas.github.io/faas-netes/
-```
-
-Create a secret named `basic-auth` in the `openfaas` namespace:
-
-```bash
-# generate a random password
-password=$(head -c 12 /dev/urandom | shasum| cut -d' ' -f1)
-
-kubectl -n openfaas create secret generic basic-auth \
---from-literal=basic-auth-user=admin \
---from-literal=basic-auth-password=$password 
-```
-
-Install OpenFaaS with Helm:
-
-```bash
-helm upgrade --install openfaas ./chart/openfaas \
---namespace openfaas \
---set functionNamespace=openfaas-fn \
---set operator.create=true \
---set securityContext=true \
---set basic_auth=true \
---set exposeServices=false \
---set operator.createCRD=true
-```
-
-Wait for OpenFaaS Gateway to come online:
-
-```bash
-watch curl -v http://openfaas.istio.example.com/heathz 
-```
-
-Save your credentials in faas-cli store:
-
-```bash
-echo $password | faas-cli login -g https://openfaas.istio.example.com -u admin --password-stdin
-```
-
-### Canary deployments for OpenFaaS functions
-
-Create a general available release for the `env` function version 1.0.0:
-
-```yaml
-apiVersion: openfaas.com/v1alpha2
-kind: Function
-metadata:
-  name: env
-  namespace: openfaas-fn
-spec:
-  name: env
-  image: stefanprodan/of-env:1.0.0
-  resources:
-    requests:
-      memory: "32Mi"
-      cpu: "10m"
-  limits:
-    memory: "64Mi"
-    cpu: "100m"
-```
-
-Create a canary release for version 1.1.0:
-
-```yaml
-apiVersion: openfaas.com/v1alpha2
-kind: Function
-metadata:
-  name: env-canaray
-  namespace: openfaas-fn
-spec:
-  name: env-canaray
-  image: stefanprodan/of-env:1.1.0
-  resources:
-    requests:
-      memory: "32Mi"
-      cpu: "10m"
-  limits:
-    memory: "64Mi"
-    cpu: "100m"
-```
-
-Create an Istio virtual service with 10% traffic going to canary:
-
-```yaml
-apiVersion: networking.istio.io/v1alpha3
-kind: VirtualService
-metadata:
-  name: env
-  namespace: openfaas-fn
-spec:
-  hosts:
-  - env
-  http:
-  - route:
-    - destination:
-        host: env
-      weight: 90
-    - destination:
-        host: env-canary
-      weight: 10
-    timeout: 30s
-```
-
-Test traffic routing (one in ten calls should hit the canary release):
-
-```bash
- while true; do sleep 1; curl -sS https://openfaas.istio.example.com/function/env | grep HOSTNAME; done 
- 
-HOSTNAME=env-59bf48fb9d-cjsjw
