Azure Kubernetes Service: Host ASP.NET Core 3.0 app in Docker Windows Server containers

Kubernetes has production level support for Windows nodes and Windows containers starting v1.14. The preview of Windows Server containers in Azure Kubernetes Service was announced recently and in this article I am going to share steps needed to run Windows containers in AKS.

  • Create a ASP.NET Core 3.0 (preview) application
  • Build and Publish Docker Image (Windows Server 2019)
  • Deploy ASP.NET Core 3.0 application to Windows nodes in Azure Kubernetes Service cluster

The dev tools used to develop these components are Visual Studio 2019/VS Code/Visual Studio for Mac, Docker for Windows (Docker CE) & Kubectl. AKS Dashboard as well as kubectl commands are used to create Kubernetes resources in AKS. The source code is available for download at GitHub.

Ingest Azure Redis Cache messages into Elasticsearch, Logstash and Kibana cluster deployed in Azure Kubernetes Service (AKS)

This is third article on the series on deploying Elasticsearch, Logstash and Kibana (ELK) in Azure Kubernetes Service (AKS) cluster. The first article covered deploying non-SSL ELK to AKS and consuming messages from Azure Event Hub. The second article described how to secure communications in ELK and use Azure AD SAML based SSO for Kibana and Elasticsearch. In this article I am going to share steps needed to ingest Azure Redis Cache messages into Elasticsearch using Logstash’s Redis plugin.

Azure Redis Cache is based on the popular open-source Redis cache. It is typically used as a cache to improve the performance and scalability of systems that rely heavily on backend data-stores. Logstash’s Redis plugin will read events from Redis instance. I will create a Logstash event processing pipeline where I will define Redis as input and Elasticsearch as output. The component diagram has been updated to add Azure Redis Cache integration.

The dev tools used to develop these components are Visual Studio for Mac/VS Code, AKS Dashboard, kubectl, bash and openssl. The code snippets in this article are mostly yaml snippets and are included for reference only as formatting may get distorted thus please refer to GitHub repository for formatted resources.

Azure Dev Spaces – Deploying Angular and ASP.net Core App to Azure Kubernetes Service (AKS)

This article will show the ease of running and deploying containers in Azure Kubernetes Service (AKS) with minimal dev machine setup with Azure Dev Spaces. I am going to reuse sample application components from my previous article on AKS. With Azure Dev Spaces, you can develop on Windows, Mac, or Linux using familiar tools like Visual Studio, Visual Studio Code, or the command line. I have chosen Visual Studio Code on Mac.

In this article, I will share the steps needed to deploy sample application I created in Angular and ASP.net Core Web API using Azure Dev Spaces.

At time of writing this article Azure Dev Spaces is in preview and is isn’t available in all regions.

Azure Kubernetes Service (AKS) – Deploying Angular, ASP.NET Core and SQL Server on Linux

Azure Kubernetes Service (AKS) makes it simple to deploy a managed Kubernetes cluster in Azure. The sample application for this article is developed in Angular, ASP.net core and SQL Server. I will go through the steps needed to deploy these components to AKS.

The dev tools used to develop these components are Visual Studio for Mac/Visual Studio 2017 and Visual Studio Code. AKS Dashboard as well as kubectl commands are used to create Kubernetes resources in AKS.

The sample use case is a front end app (Angular) which loads users from Web API (ASP.net Core) and these users are saved in SQL Server DB. The steps needed to deploy these components to AKS are

  • SQL Server on Linux 
    • Create PersistentVolumeClaim
    • Create Secret to specify sa user password
    • Create service for SQL Server
    • Create deployment for SQL Server
  • ASP.net Core Web API 
    • Create ASP.net Core Web API sample application
    • Create a Docker Hub repository
    • Create a docker image 
    • Publish docker image to Docker Hub 
    • Create service for ASP.net Core Web API
    • Create deployment for ASP.net Core Web API 
  • Angular App 
    • Create an Angular App sample application
    • Create a Docker Hub repository
    • Create a docker image 
    • Publish docker image to Docker Hub 
    • Create service for Angular App
    • Create deployment for Angular App
