Importing an Existing Save to Your Factorio Kubernetes Server

Overview

This article shows how to import an existing Factorio world save into your Kubernetes server. Rather than starting fresh, you can continue an existing factory by uploading your save file and configuring the server to load it on startup.


Tip:	Having trouble? See v0.11.2 for what your setup should look like after completing this article.

Before You Begin

Prerequisites

Factorio Kubernetes Server completed (core server running)

Upload Save File

Copy to Pod

POD=$(kubectl get pod -n factorio -l app=factorio-factorio-server-charts -o jsonpath='{.items[0].metadata.name}')
kubectl cp ~/<path-to-save-file>.zip factorio/$POD:/factorio/saves/

Verify Contents

kubectl exec -n factorio $POD -- ls -la /factorio/saves/

Configure Save Loading

HelmRelease (Update)

Update the save name in k8s/apps/factorio/helmrelease.yaml:

factorioServer:
  save_name: 'your-save-name' # Must match uploaded filename (without .zip)
  load_latest_save: false # Always load save_name, not most recent

Deploy Changes

Commit Changes

cd ~/homelab
git add k8s/apps/factorio/helmrelease.yaml
git commit -m "feat(factorio): switch to existing save"
git push

Reconcile Flux

flux reconcile source git flux-system && flux reconcile kustomization sync

Verify Save Loaded

Check Logs

POD=$(kubectl get pod -n factorio -l app=factorio-factorio-server-charts -o jsonpath='{.items[0].metadata.name}')
kubectl logs -n factorio $POD -c factorio-factorio-server-charts | grep -i "loading map"

Expected:

Loading map /factorio/saves/your-save-name.zip: XXXXXX bytes.
