Persistent Storage and Volumes using Kubernetes on Azure with AKS or Azure Container Service
Many applications hosted in a Docker container need a volume to store data on or to read from. The data can’t be stored in the Docker container itself because the data will be lost after a restart or when the container crashes. Persistent Storage has an independent lifecycle of a Pod. This blogposts shows the most used possibilities to use persistent storage using Kubernetes on Azure.
Logging to Azure Application Insights from .NET Core 2 running in a Docker Container (or Azure webapp)
Logging in .NET Core 2 is made really easy.
There is a generic logger implementation which logs to the Console and to Application Insights by default. You only have to configure the instrumentationkey like this:

Automate the deployment of .NET Core 2 Docker containers to Kubernetes with Azure Container Service and Azure Container Registry using VSTS
Previous blogpost coveres all steps to create a Docker Image from a .NET Core 2 WebAPI application on your local machine. After that, the Docker Image was pushed to Azure Container Registry (ACR). The deployment to Kubernetes pulled this Docker Image from ACR and runs a number of instances. All steps were executed manually. Let’s automate this using VSTS.
