Unifi-controller mongodb fails to setup socket

LSIO Discussion Container Support

Hi,

I’m trying to get the unifi-controller running on k8s. It works when I don’t use persistent volumes, when I use a hostPath volume mongodb fails to bind a socket. PGID/PUID 1000 is the id of the docker user in minikube, it has root and write access to the host/unificonfig folder.

Anyone have any idea on whats going on?

SETUP:
Ubuntu 19.10
minikube

k8s-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: unifi-controller
  labels:
    app: unifi-controller
spec:
  replicas: 1
  selector:
    matchLabels:
      app: unifi
  template:

    spec:
      containers:

        image: linuxserver/unifi-controller
        volumeMounts:
        - mountPath: /config
          name: unifi-storage
        env:
          - name: PGID
            value: "1000"
          - name: PUID
            value: "1000"
      volumes:
      - name: unifi-storage
        hostPath:
          type: Directory
          path: /host/unificonfig
