I am trying to run a Factorio game server on Kubernetes (hosted on GKE).
I have setup a Stateful Set with a Persistent Volume Claim and mounted it in the game server's save directory.
I would like to upload a save file from my local computer to this Persistent Volume Claim so I can access the save on the game server.
What would be the best way to upload a file to this Persistent Volume Claim?
I have thought of 2 ways but I'm not sure which is best or if either are a good idea:

Now we have a disk available to be used as PV in GKE. Next step is to, Create a Persistent volume named app-storage from the gke-pv disk. To use the persistent volume with the pod, we will create a persistent volume claim with the same name we use in the PV claimRef , ie app-storage-claim.
First, find out your pvc's mountPath. Your data sits there. Second, you can access it from the pod that uses the PersistentVolumeClaim. Fire up a terminal on the pod and use your favourite tools like ls and df to list files or see stats of the volume usage.
PVCs are requests for those resources and also act as claim checks to the resource. So a persistent volume (PV) is the "physical" volume on the host machine that stores your persistent data. A persistent volume claim (PVC) is a request for the platform to create a PV for you, and you attach PVs to your pods via a PVC.
It turns out there is a much simpler way: The kubectl cp command.
This command lets you copy data from your computer to a container running on your cluster.
In my case I ran:
kubectl cp ~/.factorio/saves/k8s-test.zip factorio/factorio-0:/factorio/saves/ This copied the k8s-test.zip file on my computer to /factorio/saves/k8s-test.zip in a container running on my cluster.
See kubectl cp -h for more more detail usage information and examples.
