When copying volume mounts that use multiple subPaths, only the first is copied

[matthew117]

Describe the bug When using Bridge to Kubernetes to redirect a deployment that has multiple volumeMounts using subPath to selectively sync and rename some files, only the first file from each mount is downloaded locally.

I have a KubernetesLocalProcessConfig.yaml that looks like:

version: 0.1
volumeMounts:
  - name: company-app-fileshare
    localPath: C:\company-app
  - name: company-app-config
    localPath: C:\company-app
env:
  - name: LOCAL_SETTINGS_PATH
    value: $(volumeMounts:company-app-fileshare)/app/app-settings.json
  - name: LOCAL_SECRETS_PATH
    value: $(volumeMounts:company-app-fileshare)/app/app-secrets.json
  - name: LOCAL_SERVICES_PATH
    value: $(volumeMounts:company-app-config)/app/services.json

and my K8s deployment looks like:

volumeMounts:
  - name: company-app-config
    mountPath: /app/service_discovery-settings.json
    subPath: service_discovery-settings.json
  - name: company-app-config
    mountPath: /app/services.json
    subPath: services.json
  - name: company-app-fileshare
    mountPath: /app/app-secrets.json
    subPath: company-app.json
  - name: company-app-fileshare
    mountPath: /app/app-settings.json
    subPath: company-app.json
  - name: company-app-fileshare
    mountPath: /app/tenants-settings.json
    subPath: company-app.json

I realise that the setup is a bit weird with one file from the fileshare being mounted as several different names but it happens with the config map that uses different keys too.

Mention the platform you are using VScode and AKS

To Reproduce Steps to reproduce the behavior: Create a pod with a mount that has mounts multiple files using subPath from one volume source:

volumeMounts:
  - name: company-app-config
    mountPath: /app/service_discovery-settings.json
    subPath: service_discovery-settings.json
  - name: company-app-config
    mountPath: /app/services.json
    subPath: services.json

Example config map:

apiVersion: v1
kind: ConfigMap
metadata:
  name: company-app-config
data:
  service_discovery-settings.json: '{"useServiceDiscoveryFile": true }'
  services.json: '{"service": "127.0.0.1" }'

Setup your KubernetesLocalProcessConfig.yaml to mount the volume

version: 0.1
volumeMounts:
  - name: company-app-config
    localPath: C:\company-app
env:
  - name: LOCAL_SETTINGS_PATH
    value: $(volumeMounts:company-app-config)/app/service_discovery-settings.json
  - name: LOCAL_SERVICES_PATH
    value: $(volumeMounts:company-app-config)/app/services.json

Expected behavior All files are available locally.

It still happens but I switched to using a pre launch task that performs a bunch of kubectl cp commands

Same issue happening on my end with the latest version
