Background Workers in Azure Container Apps with KEDA

Mon, 17 Oct 2022 13:23:33 +0000

Azure Container Apps has quickly evolved and become one of the most popular platforms to run containerized workloads in Azure. This article will look at how to run Background Workers in Azure Container Apps leveraging built-in KEDA.

Developers can use Azure Container Apps to run simple cloud-native applications leveraging popular underlying technologies like Kubernetes, Dapr, and KEDA. Before we dive into building and running a background worker in Azure Container Apps, let’s do a quick refresher on what KEDA is and what it can do for us.

How to Deploy Azure Container Apps with Terraform

Fri, 12 Aug 2022 18:56:47 +0000

Although we can provision and manage Azure Container Apps with Project Bicep (as explained in this article ), people keep on asking how to manage their Azure Container Apps using HashiCorp Terraform. This article demonstrates how to provision Azure Container Apps with Terraform utilizing a combination of the well-known AzureRM provider (azurerm) and the recently released AzAPI provider (azapi).

Before we dive into provisioning a sample workload, let’s look at what the AzAPI provider is and how it works.

az containerapp up - AKA amazing inner-loop performance

Fri, 29 Apr 2022 16:32:22 +0200

The Azure Container App team released a new command to simplify the deployment process. With az containerapp up, you can deploy your workload to Azure Container Apps (ACA) with one command. This article demonstrates how to use az containerapp up and how you can tailor its behavior to meet your requirements.

What does `az containerapp up` actually do?

You can think of az containerapp up as a meta-command that will spin up all necessary resources to take your application source and run it in ACA. Under the covers, it does the following

Managed Identities With Azure Container Apps

Thu, 14 Apr 2022 13:21:20 +0000

Yesterday (13th of April 2022), we saw a couple of new features appearing in Azure Container Apps (ACA). This article will use managed identities with Azure Container Apps, which allows us to authenticate and rely on Role-Based Access Control (RBAC) when interacting with other Azure services. Before we dive into using managed identities in Azure Container Apps, let’s do a quick refresher about managed identities to bring everyone on track.

Custom health probes with Azure Container Apps

Fri, 25 Mar 2022 11:41:56 +0000

In Kubernetes, individual probes like liveness, readiness, and startup are mission-critical when deploying applications. Kubernetes uses probes to determine the health of containers in a Pod. Kubernetes may restart Pods because of failing probes. On top of that, Kubernetes uses probes to determine if a particular container can deal with incoming requests. Kubernetes Services will route incoming requests to containers that made it to the Ready state. If a readiness probe is defined on a container, that container must successfully respond to the probe invocation to become Ready.

How to run your own Helm Repository on Azure Container Apps

Tue, 15 Mar 2022 15:29:00 +0000

Do you use Helm charts for packaging and deploying your stuff to Kubernetes? Have you ever thought about creating your own Helm repository to store and distribute your charts? This article explains how to take ChartMuseum and run it on Azure Container Apps backed by an Azure Storage Account. You can find all source code shown in this example in the 005-chartmuseum folder of my Azure Container Apps samples repository on GitHub .

Exposing gRPC services in Azure Container Apps

Mon, 07 Feb 2022 11:06:35 +0000

In my recent webinar on Azure Container Apps, an attendee asked if gRPC services could be exposed. Although I was pretty sure this was possible, I asked the attendee for some patience because I wanted to try this independently. Long story short, it’s possible. This post demonstrates how to expose gRPC services with a simple .NET 6 gRPC API and a corresponding client. We’ll also talk about a small glitch that may prevent your gRPC services hosted in Azure Container Apps from being accessible.

Traffic split in Azure Container Apps

Thu, 04 Nov 2021 18:45:15 +0000

With Azure Container Apps (ACA), Microsofts latest serverless runtime for containerized workloads in Azure, we can customize certain aspects of traffic routing on the ingress level. This article will look at traffic split and configure a relatively simple API to leverage a tailored traffic split configuration in Azure Container Apps. If you are new to Azure Container Apps, consider reading my article “Introduction to Azure Container Apps” first.

What is traffic split

First, let’s quickly revisit what traffic split is. Traffic split is a mechanism that routes configurable percentages of incoming requests (traffic) to various downstream services. See the following picture, which shows the relation between ACA ingress controller, traffic split configuration, and downstream services (or revisions in the case of ACA):

How to deploy Azure Container Apps with Bicep

Wed, 03 Nov 2021 19:21:33 +0000

Although Azure Portal and Azure CLI provide a decent experience to deploy Azure Container Apps, I prefer using Infrastructure as Code (IaC) to deploy and manage my cloud infrastructure. That said, this post guides you through the process of deploying Azure Container Apps using Bicep.

!Note that container apps are moving namespace. In March 2022, ACA will shift from the Microsoft.Web namespace to Microsoft.Apps. Everything described here should still work, but you have to change the namespace!

Introduction to Azure Container Apps

Tue, 02 Nov 2021 23:36:24 +0000

During Ignite 2021, Microsoft announced the public preview of Azure Container Apps, a fully managed serverless container runtime for building and running modern applications at scale.

The announcement of #AzureContainerApps was definitely my personal highlight at #MSIgnite so far 🚀 pic.twitter.com/zbHaYotIWi
