Serverless Containers with Azure Container Apps @ BASTA Spring 2023

Containerisierte Anwendungen endlich einfach in Kubernetes betreiben, ohne auf Skalierung und Robustheit zu verzichten? All das, ohne dass wir Kubernetes administrieren und beherrschen müssen? Dieses Versprechen gibt Azure Container Apps (ACA), der neuste Serverless-Dienst von Microsoft Azure. Doch was bietet ACA wirklich? Welche Limitierungen gibt es aktuell und werden wir tatsächlich in der Lage sein, uns auf das Lösen von fachlichen Anforderungen zu konzentrieren, anstatt die Infrastruktur zähmen zu müssen? Diese und weitere Fragen beantwortet Azure MVP und Cloud-Native-Enthusiast Thorsten Hans in seinem Vortrag.

Lernen Sie den neuen Serverless-Dienst kennen und sehen Sie, wie die Open-Source-Projekte Dapr und KEDA dazu beitragen, containerbasierte Anwendungen auch ohne Kubernetes professionell zu betreiben.

6. What is Azure Container Apps? • Serverless platform to run containerized and cloud-native applications • Built on top of battle-proven open-source projects • Kubernetes • Envoy • Dapr • KEDA • Hides most of the complexicity from us as customers Introduction
7. Why do we need yet another service for containers? • There is no serverless pricing-model for Azure Kubernetes Service (AKS) • AKS (and vanilla Kubernetes) is complex • It’s hard to find, hire, and keep people that really know Kubernetes • Azure Container Instances and Web App for Containers have some “glitches” and “gotchas” Introduction
8. The new Azure landscape for containers* Introduction Azure WebApps for Containers Azure Container Instances Azure Container Apps Azure Kubernetes Service * Azure has more services that can run containers, however those are typically a bit more specialized

14. Supported types of apps Azure Container Apps Capabilities https://learn.microsoft.com/en-us/azure/container-apps/overview
15. Ingress (Envoy) • Envoy https://www.envoyproxy.io/ acts as Ingress controller for your workloads • Apps could be exposed to the internet • We can use traffic split (see SMI Spec) https://github.com/servicemeshinterface/smi- spec/blob/main/apis/traffic-split/v1alpha4/traffic-split.md • Apps hosted in the same environment, can interact with each other • In this case, think of a regular Kubernetes service FQDN myservice.mynamespace.svc.cluster.local Azure Container Apps Capabilities
16. Microservice (with Dapr) • Dapr https://dapr.io is part of Azure Container Apps • Dapr simplifies building distributed application architectures • Dapr components are injected automatically • leveraging Kubernetes sidecar-pattern • Dapr is 100% optional! Azure Container Apps Capabilitites
17. Autoscaling with KEDA (Kubernetes Event Driven Autoscaling) • KEDA https://keda.sh allows you to scale workloads using scalers • Scalers define scaling-behavior due to external or internal signals • KEDA has 50+ built-in scalers like for example • Azure Service Bus Queue, Redis, Apache Kafka, … • Scaling configuration is part of the overall deployment manifest Azure Container Apps Capabilitites

21. Consuming Docker Images • Containers can be consumed from any kind of Container registry • Public and Private Container registries are supported • Authentication is supported via • Username and Password (or Tokens) • System-Assigned or User-Assigned Managed Service Identity (MSI) Hands-On Azure Container Apps
22. How to deploy Azure Container Apps • Azure Container Apps are regular Azure Resource Manager (ARM) entities • Azure Container Apps can be provisioned using • Project Bicep • Pulumi • Terraform using the AzAPI provider • finally, also available in the AzureRM provider (since January 2023) • Azure CLI integration is available via extension Hands-On Azure Container Apps
23. Provision and Deploy Azure Container Apps Demo
24. Observability • Seamless Observability integration • Container logs will be streamed to Azure Log Analytics Workspace (or Azure Monitor) • Log Analytics workspace should be linked to the Azure Container App Environment • Logging agents enrich logs written to STDOUT and STDERR with data like • Container App Name • Revision & Environment Name • Container Image Repository & Tag Hands-On Azure Container Apps
25. How to investigate and troubleshoot • Query Log Analytics Workspace for individual logs • Directly access log stream in your terminal or Azure Portal • Shell access to containers using your terminal or Azure Portal Troubleshooting
