IdentityServer with ASP.NET Core Identity and MongoDB as Database [Detailed Guide]

Last Updated: August 18, 2021

In this tutorial we will set up IdentityServer with ASP.NET Core Identity Core from the absolute beginning. Also the ASP.NET Identity is configured with a MongoDB database.

Kubernetes Persistent volumes (PV) and Persistent Volume Claim (PVC)

Last Updated: June 28, 2021

Persistent Volumes (PV) are storages in the Kubernetes cluster which are persistent in nature. The PV has a lifecycle independent of any individual pod which is using the PV. A Persistent Volume remains outside the Pod unlike emptyDir volume (emptyDir remains inside the Pod) so even if a Pod crashes there is no risk of the volume getting ruined.
