Create traffic

Create a pod that you can log into

1. Create a pod that can host some command line tools

cat <<EOF | kubectl create -f -
apiVersion: v1
kind: Pod
metadata:
  name: centos
spec:
  containers:
  - name: centoss
    image: centos
    ports:
    - containerPort: 80
    command:
    - sleep
    - "3600"
EOF

2. Log into that pod

kubectl exec -ti centos -- /bin/bash

3. Run a query against a service from the inside

for i in {1..10000}; do curl -s -w "%{time_total}\n" -o /dev/null http://nameofyourservice; done

4. Cleanup of your pod

kubectl delete pod centos

Configure a horizontal pod autoscaler

https://kubernetes.io/docs/tasks/run-application/horizontal-pod-autoscale/

Select a deployment

kubectl autoscale deployment nginx --cpu-percent=20 --min=1 --max=8

Trigger a load generator via aci

create resource group

az group create --name myResourceGroup --location westeurope

create aci helloworld instance

az container create --name mycontainer --image denniszielke/aci-helloworld --resource-group myResourceGroup --ip-address public --port 80

retrieve the endpoint that you want to post against (including path)

PUBLIC_IP="x.x.x.x"
az container create --name myloadrunner3 --image denniszielke/load-generator --resource-group myResourceGroup --environment-variables ENDPOINT=$PUBLIC_IP
