Quick Guide to Azure Container Apps
Now that Azure Container Apps (ACA) is generally available, it is time for a quick guide. These quick guides illustrate how to work with a service from the command line and illustrate the main features. Prerequisites All commands are run from bash in WSL 2 (Windows Subsystem for Linux 2 on Windows 11) Azure CLI…
azureA look at some of Azure Container App’s new features
A while ago, I created a YouTube playlist about Azure Container Apps. The videos were based on the first public preview. At the time, several features were missing or still needed to be improved (as expected with a preview release): An easy way to create a container app, similar to az webapp up Managed Identity…
azureTrying out WebAssembly on Azure Kubernetes Service
Introduction In October 2021, Microsoft announced the public preview of AKS support for deploying WebAssembly System Interface (WASI) workloads in Kubernetes. You can read the announcement here. In short, that means we can run another type of workload on Kubernetes, besides containers! WebAssembly is maybe best known for the ability to write code with languages…
cloudBuilding a GitHub Action with Docker
While I was investigating Kyverno, I wanted to check my Kubernetes deployments for compliance with Kyverno policies. The Kyverno CLI can be used to do that with the following command: kyverno apply ./policies –resource=./deploy/deployment.yaml To do this easily from a GitHub workflow, I created an action called gbaeke/kyverno-cli. The action uses a Docker container. It…
automationAKS Pod Identity with the Azure SDK for Go
In an earlier post, I wrote about the use of AKS Pod Identity (Preview) in combination with the Azure SDK for Python. Although that works fine, there are some issues with that solution: the container image is around 1GB, which is quite large (it is based on tiangolo/uvicorn-gunicorn-fastapi:python3.7) as expected, the image contains many vulnerabilities…
azureUsing the Dapr InfluxDB component
A while ago, I created a component that can write to InfluxDB 2.0 from Dapr. This component is now included in the 0.10 release. In this post, we will briefly look at how you can use it. If you do not know what Dapr is, take a look at https://dapr.io. I also have some videos…
azureGetting started with Consul on Kubernetes
Although I have heard a lot about Hashicorp’s Consul, I have not had the opportunity to work with it and get acquainted with the basics. In this post, I will share some of the basics I have learned, hopefully giving you a bit of a head start when you embark on this journey yourself. Want…
azureCreating a Kubernetes operator on Windows and WSL
I have always wanted to create a Kubernetes operator with the operator framework and tried to give that a go on my Windows 10 system. Note that the emphasis is on creating an operator, not necessarily writing a useful one 😁. All I am doing is using the boilerplate that is generated by the framework.…
containersStreamlined Kubernetes Development with Draft
A longer time ago, I wrote a post about draft. Draft is a tool to streamline your Kubernetes development experience. It basically automates, based on your code, the creation of a container image, storing the image in a registry and installing a container based on that image using a Helm chart. Draft is meant to…
apiUsing TensorFlow models in Go
Image via http://www.vpnsrus.com In earlier posts, I discussed hosting a deep learning model such as Resnet50 on Kubernetes or Azure Container Instances. The model can then be used as any API which receives input as JSON and returns a result as JSON. Naturally, you can also run the model in offline scenarios and directly from…
aiBuilding a real-time messaging server in Go
Often, I need a simple real-time server and web interface that shows real-time events. Although there are many options available like socket.io for Node.js or services like Azure SignalR and PubNub, I decided to create a real-time server in Go with a simple web front-end: For a real-time server in Go, there are several options.…
apiResNet50v2 classification in Go with a local container
To quickly go to the code, go here. Otherwise, keep reading… In a previous blog post, I wrote about classifying images with the ResNet50v2 model from the ONNX Model Zoo. In that post, the container ran on a Kubernetes cluster with GPU nodes. The nodes had an NVIDIA v100 GPU. The actual classification was done…
aiDeploying Azure Cognitive Services Containers with IoT Edge
Introduction Azure Cognitive Services is a collection of APIs that make your applications smarter. Some of those APIs are listed below: Vision: image classification, face detection (including emotions), OCR Language: text analytics (e.g. key phrase or sentiment analysis), language detection and translation To use one of the APIs you need to provision it in an…
analyticsUsing certmagic to add SSL to webhookd
A while ago, I stumbled upon https://github.com/ncarlier/webhookd. It is a simple webhook server, written in Go, that can execute shell scripts. To use it, simply install it on a Linux box and execute it. By default, the executable looks at the ./scripts folder and maps each shell script to a URL you can call. It…
apiDraft: a simpler way to deploy to Kubernetes during development
If you work with containers and work with Kubernetes, Draft makes it easier to deploy your code while you are in the earlier development stages. You use Draft while you are working on your code but before you commit it to version control. The idea is simple: You have some code written in something like…
