Azure Group Controller

A Kubernetes controller that creates a AzureGroup resource with a list of members and some basic information on the group.
The controller will continuously reonconsile the AzureGroup resource.

Prerequisites

For deploying:

• Helm, https://helm.sh/docs/intro/install/
• Kubectl, https://kubernetes.io/docs/tasks/tools/

For developing:

• Kind, https://kind.sigs.k8s.io/docs/user/quick-start/
• Rust, https://www.rust-lang.org/tools/install
• Just, https://github.com/casey/just

Install

Start be creating a default App Registration in your Azure tenant. Don't chose any Platform, just give it a name.
Add the GroupMember.Read.All and User.ReadBasic.All Application Permissions to the App Registration and create a new client secret.
If the maximun expiration date of years is not enough for you, use the az cli to set as many years as you want.

Create a Kubernetes secret in your cluster containing the Azure tenant, client ID and secret.

kubectl create secret generic az-group-manager \
  --from-literal=tenant-id=<uuid> \
  --from-literal=client-id=<uuid> \
  --from-literal=client-secret=<secret>

Add the Helm repository and update.

helm repo add kerwood https://kerwood.github.io/helm-charts
helm repo update

Install the controller.

helm install az-group-manager kerwood/az-group-controller --namespace <namespace>

How to use it

Create a AzureGroupManager resources with the UUID of a Azure Group in the spec.

apiVersion: kerwood.github.com/v1
kind: AzureGroupManager
metadata:
  name: my-azure-group-name-can-be-anything
spec:
  groupUid: 00b9c3c9-09d1-4e58-bd89-ec3ebcfb47e6

The controller will create a child resource with the group information.
