Drawio is one of those tools I actually tend to use. It is great for flow charts, mind maps or floor design. you draw up what you need and then download via pdf.

  • Persistent storage for config
  • Static IP via MetalLB

Create Namespace

kubectl create namespace tools

Create Persistent Volume (PVC)

Note: The official image is stateless, but you can add volume mounts if needed for custom configs or static files.

Save as drawio-pvc.yaml:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: drawio-config
  namespace: tools
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  storageClassName: longhorn

Apply it:

kubectl apply -f drawio-pvc.yaml

Create Deployment and Service

Save the following as drawio.yaml:

apiVersion: apps/v1
kind: Deployment

    matchLabels:
