How to run dat inside kubernetes

Is anyone successfully running dat from inside kubernetes? The following Deployment is currently working for me, but it would be nice to avoid requiring hostNetwork: true. Also wondering how to best specify the .dat keys. I am currently sharing them from the host which works all right in this scenario, but isn’t a very general solution. Also, the node this container is running on essentially has a public ip which might be making this easier. I haven’t yet tested it from inside kubernetes on a node without a public ip.

apiVersion: apps/v1
kind: Deployment
metadata:
  name: dat-server
  labels:
    app: dat-server
spec:
  replicas: 1
  selector:
    matchLabels:
      app: dat-server
  template:
    metadata:
      labels:
        app: dat-server
    spec:
      volumes:
        - name: nfs
          hostPath:
            path: /mnt/nfs
            type: Directory
        - name: dat-key
          hostPath:
            path: /root/.dat
            type: Directory
        # kubernetes secrets can't have subdirectories so this doesn't work
        # - name: dat-key
        #   secret:
        #     secretName: dat-key
      containers:
      - name: dat-server
        image: registry/dat:latest
        command:
          - "dat"
          - "share"
          - "/mnt/nfs/"
          # - "sleep"
          # - "300"
        volumeMounts:
          - name: nfs
            mountPath: /mnt/nfs
          - name: dat-key
            mountPath: /root/.dat
      # this gets dat network access, otherwise i get symmetric nat errors from dat doctor
      hostNetwork: true
      # sort of a hack, run this only on the node running the nfs server
      nodeSelector:
        nfs: server
# ---
# # I was still unable to access dat with this service
# kind: Service
# apiVersion: v1

@dwiel that’s great. Can you share your dockerfile to see your configuration and hopefully make it run too?

Thanks @RangerMauve for a ping!

Thanks, btw I’ve tested the above solution on nodes that dont have public ips with success. Would still like avoid hostNetwork: true, but it is running. I’ve also had it working in docker with udp and TCP ports opened as well.
