Kubernetes: ConfigMaps with .NET
Kubernetes ConfigMaps with .NET Core This tutorial will cover how to mount a Kubernetes ConfigMap into a pod and how to read that configuration in .NET. I will also demonstrate the different ways a .NET application can read configuration from an appsettings.json file. One demonstration will reload configuration on change and how to listen for those changes. That does not...
Identity Server 4 ClientCredentials with POSTMAN This tutorial will demonstrate how to set up security within microservices using Identity Server 4 with OpenID. This will use a Client and Secret for microservice to microservice (machine-to-machine) communication that way a compromised microservice can't interact with resources it's not authorized to. I will also demonstrate how to use POSTMAN to get tokens,...
