brassberry-gitops: The state of my kubernetes cluster

GitOps with ArgoCD

This is the current state of my home kubernetes cluster, running on Raspberry Pis. It uses ArgoCD, Renovate and ArgoCD Image Updater for a simple and automatic update process!

Bootstrap

OS dependencies

Make sure to run the initial ansible playbook for the ubuntu-image-raspberry repository.

make all

Install Kubernetes with k0sctl, in the same repository.

k0sctl apply --config k0sctl.yaml
# Make sure you have a special kubeconfig for your project
# Otherwise you overwrite your other configs
k0sctl kubeconfig > $KUBECONFIG

You should now be able to list your nodes and kube-system pods.

kubectl get nodes
kubectl get -n kube-system pods

CRD and ns
