I am trying to run gitea 1.8.3 which now has a habit of wanting to write in generated JWT token into its own app.ini file. Previously the app.ini file could be mounted from a ConfigMap as read-only. Now I need to somehow populate the app.ini file with some data but also let the app write into that file.

I am trying to have an initContainer write out the config that is mounted in the main app. This is explained at here. When I try that example with minishift it tells me I cannot mount a hostPath due to a security constraint. I don't want to relax security so I am trying to put the configuration into a PVC. Here is the script:

#!/bin/bash
cat | oc create -f  - <<EOF
---
apiVersion: "v1"
kind: "PersistentVolumeClaim"
metadata:
  name: "config-data-claim"
spec:
  accessModes:
    - "ReadWriteMany"
  resources:
    requests:
      storage: "1Gi"
---
apiVersion: v1
kind: Pod
metadata:
  name: my-app
spec:
  containers:
  - name: realworld
    image: docker.io/simonmassey/react-redux-realworld:v0.0.2
    env:
    - name: API_ROOT
      value: https://conduit.productionready.io/api
    volumeMounts:
    - mountPath: /data
      name: config-data-claim
  initContainers:
  - name: config-data
    image: busybox
    command: ["echo","-n","{'address':'10.0.1.192:2379/db'}", ">","/data/config"]
    volumeMounts:
    - mountPath: /data
      name: config-data-claim
  volumes:
  - name: config-data-claim
    persistentVolumeClaim:
      claimName: config-data-claim
EOF

This creates fine but when I used the minishift web console to go into a terminal in the pod and run ls -al /data the pvc it is empty. The console shows that the initContainer ran successfully.

Why is the pvc folder /data not populated by the initContainer?

I am running:

$ oc version

The server is minishift running opensheft 3.11 started with:

brew cask install minishift
