Scaling containers with KEDA

SLide deck from the presentation done at the PD Tech Fest event in Manila on 10th August 2019. The talk demonstrated the use of Kubernates-based Event Driven Autoscaling (KEDA) features. The demo shows how to scale RabbitMQ consumer based on the number of messages in a queue.

7. Scale k8s objects: Kubectl scale –replicas=3 processor-deployment.yml Kubectl scale –replicas=3 deployment/rabbitmq-consumer Scale AKS cluster: az aks scale --resource-group myResourceGroup \ --name myAKSCluster \ --node-count 1 \ --nodepool-name <your node pool name>
8. kubectl autoscale deployment php-apache \ --cpu-percent=50 \ --min=1 \ --max=10
9. az feature register --name VMSSPreview -- namespace Microsoft.ContainerService az aks create \ --resource-group myResourceGroup \ --name myAKSCluster \ --node-count 1 \ --enable-vmss \ --enable-cluster-autoscaler \ --min-count 1 \ --max-count 3
