Contrib.IdentityServer4.KubernetesStore

Allows IdentityServer4 to fetch Clients, API Resources, etc. using Kubernetes Custom Resources rather than a database.

Usage

Identity Server Project

Add the Contrib.IdentityServer4.KubernetesStore NuGet package to your existing IdentityServer4 project. You can then activate it in your Startup.cs:

services.AddKubeClient(Configuration.GetSection("Kubernetes"))
        .AddIdentityServer(...)
        .AddKubernetesConfigurationStore();

This will default to connecting to the Kubernetes API using the Pod's service account. See the documentation of the KubeClient library for more options.

Kubernetes Resources

Register the Custom Resource Definitions in your Kubernetes cluster:

kubectl apply -f https://raw.githubusercontent.com/AXOOM/Contrib.IdentityServer4.KubernetesStore/develop/crd.yaml

You can then create Identity Server objects with Kubernetes resources.

Development

Run build.ps1 to compile the source code and create NuGet packages. This script takes a version number as an input argument. The source code itself contains no version numbers. Instead version numbers should be determined at build time using GitVersion.
