My Kubernetes cluster state managed by ArgoCD.
| Device | Specs | OS | Purpose |
|---|---|---|---|
| Lenovo ThinkCentre M75q-1 | Ryzen 5 Pro 3400GE + 16GB RAM + 512GB NVMe SSD + 1TB SATA SSD | NixOS | k8s master & worker node |

To access my apps, I expose them directly on the internet with port-forwarding on my router.
- Kubernetes cluster deployed with k0s
- GitOps deployment with ArgoCD and Helm
- Fully automated HTTPS exposition of my apps using cert-manager, external-dns and ingress-nginx
- Authentication of sensitive apps with oauth2-proxy with GitLab as an OAuth2 provider
- Secrets management with external-secrets and GitLab CI/CD variables
- Simple and cheap offsite backup of my important data using OpenEBS, Velero and Backblaze B2
- Observability with Prometheus, Grafana, Loki and Opentelemetry Collector
- Alerting with Alertmanager and a Telegram Bot
- Automated updates with Renovate
- Any app you'd want to host! Currently, Nextcloud, Immich, Paperless-ngx and more (see below)

The install assumes that all external secrets are already created in a GitLab project as CI/CD variables.
Start the k0s cluster:
cd ~/homelab-gitops
sudo k0s install controller --enable-worker -c ./k0s.yaml
sudo k0s start
sleep 5
sudo k0s status
sudo k0s kubeconfig admin > ~/.kube/config
kubectl taint nodes --all node-role.kubernetes.io/master-Create the GitLab token secret used by external-secrets:
kubectl create ns external-secrets
kubectl apply -f -
apiVersion: v1
kind: Secret
metadata:
name: gitlab-secret
namespace: external-secrets
type: Opaque
stringData:
token: xxxChange the token value and type <Ctrl+D> <Enter> to create the secret.
Deploy external-secrets and ArgoCD apps:
cd ../../k8s-apps/external-secrets && helm dependency update && helm template external-secrets -n external-secrets . | kubectl apply -n external-secrets -f -
kubectl create ns argocd
cd ../../k8s-apps/argocd && helm dependency update && helm template argocd . -n argocd | kubectl apply -n argocd -f -
kubectl apply -f ../../argocd-apps/app-of-apps.yaml -n argocdCluster should be ready!
Save the GitLab token secret
kubectl get secret -n external-secrets gitlab-secret -o yaml > gitlab-secret.yamlTeardown the cluster
sudo k0s stop
sudo k0s reset -v -d
