Kubernetes Volume Setup Guide? Files get Corrupted on redployment!

Umbraco 9

Hello Every One. this is My First question in this forum.

I've been able to successfully deploy mssql2019 + volume for persistence also deploying Umbraco as Unattended on Kubernetes was a great success. I thought that it would help if I get two volumes and attach them to /wwwroot and /Views directories. Here is My manifest:

apiVersion: apps/v1
kind: Deployment
metadata:
  name:  parsa-gachkar-umb
  labels:
    app:  parsa-gachkar-umb
spec:
  selector:
    matchLabels:
      app: parsa-gachkar-umb
  replicas: 1
  strategy:
    rollingUpdate:
      maxSurge: 25%
      maxUnavailable: 25%
    type: RollingUpdate
  template:
    metadata:
      labels:
        app:  parsa-gachkar-umb
    spec:
      containers:
      - name:  parsa-gachkar-umb
        image:  docker-registry-parsa-*****/personal-website:latest
        imagePullPolicy: Always
        resources:
          requests:
            cpu: 1
            ephemeral-storage: 2G
            memory: 2G
          limits:
            cpu: 1
            ephemeral-storage: 2G
            memory: 2G
      imagePullSecrets:
      - name: registrysecret       
        ports: 
        - containerPort:  80
          name:  tcp-80
        volumeMounts:
        - name: wwwroot
          mountPath: /app/wwwroot
        - name: views
          mountPath: /app/Views
      volumes:
      - name: wwwroot
        persistentVolumeClaim:
          claimName: parsa-gachkar-umb-wwwroot-pvc
      - name: views
        persistentVolumeClaim:
          claimName: parsa-gachkar-umb-views-pvc
      restartPolicy: Always

Every thing works fine at this scenario🎉. But If I set replicas to 0 and back to 1

For whom that don't know what this means Kubernetes will just simply stop the app, delete and everything except the volumes Redeploy the app and re-mount the volumes to the folders I specified before.

Here is the issue: after redeploy Views and Media Files are Corrupted! I was wondering if anyone else managed to deploy Umbraco on Kubernetes and How did him/her Persist these folders. If any one knows how to solve this issue I'd appreciate his/her Help. Maybe I'm just dumb and missing something?

Ok looks like I was dumb 🤣. checked the folder from my pod's console looks like when volume attaches the disk is empty and there is no way to initialize volume with a preloaded data fixed the issue with a dirty .sh script hack 😁 cheers 🍻

here my docker file and bash script btw:

dockerfile:

# syntax=docker/dockerfile:1
FROM mcr.microsoft.com/dotnet/sdk AS build-env
WORKDIR /app

# Copy csproj and restore as distinct layers
COPY *.csproj ./
RUN curl https://api.nuget.org/v3/index.json -k
RUN dotnet restore

# Copy everything else and build
COPY . .
RUN dotnet publish -c Release -o out


# Build runtime image
FROM mcr.microsoft.com/dotnet/aspnet
WORKDIR /app
COPY --from=build-env /app/out .
COPY --from=build-env /app/out /src
COPY ./run.sh /src
RUN chmod +x /src/run.sh
ENTRYPOINT ["/src/run.sh"]

run.sh:

#!/bin/bash
{
dotnet PersonalWebsite.dll
} || { 
cp -R /src/. . && 
dotnet PersonalWebsite.dll
}
