This is the companion code for the presentation The Daemonset in the Details given at the Kubernetes Community Days (KCD) Bucharest, Romania April 2024.
To actually execute the Helm chart you will need a Kubernetes cluster
and kubectl and Helm installed.
Kind is a good way to do this locally.
You will need kind.
Once installed run make create-cluster:
ditd-presentation % make create-cluster
kind create cluster
Creating cluster "kind" ...
✓ Ensuring node image (kindest/node:v1.29.2) 🖼
✓ Preparing nodes 📦
✓ Writing configuration 📜
✓ Starting control-plane 🕹️
✓ Installing CNI 🔌
✓ Installing StorageClass 💾
Set kubectl context to "kind-kind"
You can now use your cluster with:
kubectl cluster-info --context kind-kind

ditd-presentation % make repos
