Transit from docker to k8s

[Cindia-blue]

When I use k8s to deploy epc, I got below error with the same image, could you share hints about that?

Reading configuration file epc.conf...
HSS Initialized.
MME GTP-C Initialized
MME Initialized.
Could not initialize the SGi interface.

how to translate the devices through h8s yml

devices:
- /dev/net/tun

[pgorczak]

I know almost nothing about k8s but I found an example on how to make sure the /dev/net/tun special file exists within the pod (although for use with OpenVPN).

Tl;dr they added a startup script containing this

mkdir -p /dev/net
mknod /dev/net/tun c 10 200
chmod 600 /dev/net/tun

Can you make it work like this?

Translating this to k8s language you need to add the following to your deployment manifest:

        volumeMounts:
        - mountPath: /dev/net/tun
          name: dev-tun
        securityContext:
          capabilities:
            add:
            - NET_ADMIN
            - SYS_NICE
      volumes:
      - hostPath:
          path: /dev/net/tun
          type: CharDevice
        name: dev-tun
