File upload to Azure Storage Blob using Node JS Application

This is a simple Node.js project that allows you to fill a basic form and submit. On Submit action input variables are processed and stored as a Yaml file in an Azure Blob Storage.

Getting Started

Prerequisites

Node.js installed on your machine. You can download it from https://nodejs.org/.
An Azure Storage Account. If you don't have one, you can create it in the Azure Portal.
Update file .env and replace AZURE_STORAGE_CONNECTION_STRING with your Azure Storage Account connection string.

Installation

Clone the repository:

git clone https://github.com/skumaraz2k7/nodejs-azure-ad-group-project.git
cd nodejs-azure-ad-group-project

Install dependencies:
```
npm install
```
Run the application:
```
node app.js
```
Visit http://localhost:3000 in your web browser to access the form.

Usage

Open your web browser and navigate to http://localhost:3000.
Fill in the form with the required information (AD Group Name and Group Type).
Click the "Create Group" button to submit the form.
The form data will be saved to a test.tfvars file and uploaded to the specified Azure Storage Account container.

1. Introduction

In this article, you will discover the power of Helm charts in Azure Container Registry (ACR). This post guides you through the seamless integration of Helm, enabling secure and scalable management of Helm charts within ACR, elevating your Kubernetes deployments on Azure to the next level.

2. Prerequisites

Azure Subscription
Azure Container Registry (ACR)
Helm Client (Version > 3.0)
Basic knowledge of Docker, Azure, and Container Registry

3. Setting Up Helm for Private Registry

If you don't have a Helm client, please follow the instructions here according to your OS.
I am using helm on macos, but you can use any supported OS.

Make sure you are using Helm version > 3.0

Create Helm Chart as below:

helm create myapp

This will initialise local helm charts. As a result two folders, chart and templates along with two files Chart.yaml and values.yaml are created as below:

To keep the chart simple, remove all files from templates folder.

Create deployment.yaml and service.yaml file inside templates folder using below commands

cat <<EOF > deployment.yaml apiVersion: apps/v1 kind: Deployment metadata: name: myapp-deployment labels: app: myapp spec: replicas: 3 selector: matchLabels: app: myapp template: metadata: labels: app: myapp spec: containers: - name: nginx image: nginx:1.14.2 ports: - containerPort: 80 EOF

cat <<EOF > service.yaml apiVersion: v1 kind: Service metadata: name: myapp-service spec: selector: app: myapp ports: - protocol: TCP port: 80 targetPort: 80 EOF

Packaging the chart to local archive
change directory to myapp and run below command:
helm package .

4. Pushing Helm Charts to a Private Registry

Make sure you have a container registry in your azure subscription with pull and push permission.

First authenticate to container registry as below:
helm registry login --username xxx --password xxx

I am using a service principal (app registration) which has acrpull and acrpush permission on the repo.

Now push helm chart to container registry as OCI artifact as below:
helm push myapp-0.1.0.tgz oci://skazacr.azurecr.io/helm

Check the portal to confirm the charts are pushed correctly.

5. What Next

This was a simple demonstration on how to use private registry for helm charts. In the next article I will show you how to deploy and upgrade the helm chart from private container registry.
