I'm trying to figure out the steps to setup CI/CD for an Asp.Net Core web application using AKS with VSTS. Are the steps described in https://docs.microsoft.com/en-us/vsts/build-release/apps/cd/azure/deploy-container-kubernetes valid for what I'm trying to do? Are windows container supported in AKS?
Windows support on k8s is better with Windows Server version 1709 which needs Kubernetes v1.9 (bleeding edge stable). See https://kubernetes.io/docs/getting-started-guides/windows/
Unfortunately, at this time, AKS preview only supports up to 1.8.2.
Frosty, if you can create a docker image out of your Windows machine, it can be pushed to the container registry and then deployed to Kubernetes cluster. Here are some links for reference:
Building and Pushing Windows container images: https://blog.docker.com/2016/09/build-your-first-docker-windows-server-container/
Install Azure CLI: https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest
Create Kubernetes cluster in AKS: https://coderise.io/kubernetes-cluster-on-azure-container-service/
Currently Windows container are only in private preview, and you need to enable it using Azure CLI do some steps, please refer this official docs: https://docs.microsoft.com/en-us/azure/aks/windows-container-cli. After you enable it, then you can check the 'Windows Container' option when you create node pool in your azure kubernete service account.
Windows containers are in private preview in AKS (reference); you can sign up using this form.. You can run hybrid clusters (Linux+Windows, up to 1803) using acs-engine today.
The VSTS walkthrough you linked is valid; check also this one and this one.
Update: Windows support for AKS is still a work in progress.
If your application is in ASP.Net Core, then you can host it in Linux as your code is platform independent. I have done this using Docker-file where your container is a self hosted app running on AKS.
VSTS provides a Inbuilt task to deploy to your AKS cluster in your build pipeline.
