docker build -t chzbrgr71/kubecon-api-sites:v4 .
docker build -t chzbrgr71/kubecon-api-subjects:v4 .
docker build --build-arg BUILD_DATE=`date -u +"%Y-%m-%dT%H:%M:%SZ"` --build-arg VCS_REF=`git rev-parse --short HEAD` --build-arg IMAGE_TAG_REF=v4 -t chzbrgr71/kubecon-rating-web:v4 .
  • Start with AKS cluster v1.9.1 or better
helm init --upgrade`
kubectl -n kube-system delete deploy tiller-deploy
helm init --service-account default

  • Pre-install API deployments and CosmosDB

    • Create CosmosDB
    • Set connect string in secret

    kubectl create secret generic cosmos-db-secret --from-literal=uri=''

    • Install APIs kubectl apply -f api.yaml

  • Create secret for ACR (optional)

    -> this step is not needed if service principal for AKS has rights

export ACR_SERVER=
export ACR_USER=
export ACR_PWD=

kubectl create secret docker-registry acr-secret --docker-server=$ACR_SERVER --docker-username=$ACR_USER --docker-password=$ACR_PWD [email protected]

  • OpenFaaS (Optional)

    cd faas-netes
kubectl create namespace openfaas
kubectl create namespace openfaas-fn

helm install --namespace openfaas -n openfaas \
--set functionNamespace=openfaas-fn, \
--set serviceType=LoadBalancer, \
--set rbac=false chart/openfaas/

export FAAS_GW=http://$(kubectl get svc --namespace openfaas gateway-external -o jsonpath='{.status.loadBalancer.ingress[0].ip}'):8080

echo $FAAS_GW
    • Grafana Dashboard
    helm install --name grafana stable/grafana --version 0.5.1 --set server.service.type=LoadBalancer,server.adminUser=admin,server.adminPassword=Your@Password,server.image=grafana/grafana:4.6.3,server.persistentVolume.enabled=false --namespace openfaas

echo $PROM_URL | pbcopy

    • Deploy sms-ratings function Set gateway in sms-ratings.yml Set environment: API_URL in sms-ratings.yml

    brew install faas-cli (if needed)

cd ./sms-ratings

    • Update webhooks in Twilio (4 numbers)
    export TWILIO_WEBHOOK=http://$(kubectl get svc --namespace openfaas gateway-external -o jsonpath='{.status.loadBalancer.ingress[0].ip}'):8080/function/sms-ratings

echo $TWILIO_WEBHOOK | pbcopy
    • Test a SMS
