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.
