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.

Host your ASP.NET Core 2.2 Web App with IIS (in-process and out-of-process hosting model) and deploy to Docker Windows Containers

One of the new features of ASP.NET Core 2.2 is support for hosting ASP.NET Core Web App with IIS using in-process or out-of-process hosting model. This article will cover steps needed to

  • Host ASP.NET Core 2.2 Web API with IIS using in-process hosting model
  • Host ASP.NET Core 2.2 Web API with IIS using out-of-process hosting model
  • Host ASP.NET Core 2.2 Web API in Docker Windows containers (with IIS)

In ASP.NET Core 2.2, a new ASP.NET Core Module (AspNetCoreModuleV2) has been introduced which is a native IIS module that plugs into the IIS pipeline and provides in-process or out-of-process hosting capabilities. AspNetCoreModule used to be the module in previous version.

The tools used to develop these components are Visual Studio for Mac/VS Code/VS 2017, AKS Dashboard, Docker for Desktop and kubectl.

SonarQube

SonarQube provides the capability to not only show health of an application but also to highlight issues newly introduced. I am going to configure SQL Server as backend database for SonarQube.

Add real-time web functionality to Angular application using ASP.NET Core SignalR, Azure SignalR service and Azure SignalR Service bindings for Azure Functions 2.0

This is the next part of the series on developing and deploying

  • Angular, ASP.NET Core Web API and SQL Server to Azure Kubernetes Service
  • Function Apps using Azure Functions 2.0 runtime

In this article I am going to go through steps needed to add real-time web functionality to Angular App using ASP.NET Core SignalR and Azure SignalR Service bindings for Azure Functions 2.0. The specific topics which this article is going to cover are

  • Add ASP.NET Core SignalR to ASP.NET Core 2.1 Web API
    • ASP.NET Core SignalR
    • ASP.NET Core SignalR scale out using
      • Azure SignalR Service backplane
      • Redis Cache backplane
  • Publish/Subscribe messages to SignalR Hub from Angular App
  • Publish/Subscribe messages to SignalR Hub using Azure SignalR Service bindings for Azure Functions 2.0 from Angular App
  • Build Docker images and deploy to Azure Kubernetes Service

Azure Functions 2.0: Create Function App from Docker Image (Functions triggered by Cosmos DB, Blob storage, Event Hub and SignalR service bindings)

This is second part of the series on developing and deploying Azure Functions 2.0 where I will

  • Create a function triggered by Azure Cosmos DB
  • Create Azure SignalR Service bindings for Azure Functions 2.0
  • Publish Docker Image to Docker Hub
  • Create Function App from Docker Image in Azure Portal
  • Deploy functions to Azure Kubernetes Service from VS Code

The first part of the series provides details on creating functions triggered by Azure Blob storage and Event hub in Visual Studio Code along with deploying Azure Functions to Azure Kubernetes Service (AKS).

ASP.NET Core 2.1 Web API – Load App Configuration from appsettings.json, Dockerfile environment variables, Azure Key Vault Secrets and Kubernetes ConfigMaps/Secrets

This article is second part of the series on Deploying Angular, ASP.NET Core and SQL Server on Linux to Azure Kubernetes Service (AKS) cluster. The first part, describes steps needed to deploy these components to AKS. App configuration in ASP.NET Core is based on key-value pairs established by configuration providers. Configuration providers read configuration data into key-value pairs from a variety of configuration sources. In this article I am going to share multiple ways to load App configuration in ASP.net Core Web API

  • Hosting Environment specific appsettings.json
  • Dockerfile Environment Variables
  • Kubernetes
    • Container Environment variables with data from ConfigMap/Secret
    • Populate Volume (Config file) with data stored in a ConfigMap/Secret
  • Azure Key Vault Secrets

The tools used to develop these components are Visual Studio for Mac/VS Code/VS 2017, AKS Dashboard, Docker for Desktop and kubectl. The formatting of code snippets in this article may get distorted (especially yaml), thus please refer to GitHub repository for complete source code for this article.

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.
