praveensri demonstrates how to deploy Hybrid Azure Logic Apps on a lightweight K3s Kubernetes cluster, detailing infrastructure setup, Azure Arc integration, and hybrid configuration for on-premises or edge environments.

Deploying Hybrid Azure Logic Apps on K3s for Lightweight, On-Premises Integration

Hybrid deployments of Azure Logic Apps allow organizations to run workflows close to their on-premises data for performance and integration flexibility. In this guide, praveensri outlines a practical approach using a lightweight K3s Kubernetes distribution, streamlining infrastructure needs particularly for edge or resource-constrained environments.

Why K3s?

Lightweight Kubernetes: K3s offers reduced overhead while preserving Kubernetes API compatibility, making it suitable for on-premises or edge setups.
Ideal for Hybrid Logic Apps: Lets you deploy and run Azure Logic Apps Standard near local data sources, like on-prem SQL Servers and SMB file shares, without the burden of a full Kubernetes cluster.

Deployment Steps

1. Prepare the K3s Cluster

Host Environment: Uses Windows 11 with Docker Desktop (WSL2 integration).

Software Installation:

Install Docker Desktop, ensure WSL2 is selected.

Install required tools via Chocolatey and PowerShell:

Set-ExecutionPolicy Bypass -Scope Process -Force;
iex ((New-Object System.Net.WebClient).DownloadString('https://community.chocolatey.org/install.ps1'))
choco install kubernetes-cli -y
choco install kubernetes-helm -y
choco install k3d -y

Create a single-node K3s cluster:

k3d cluster create
# Remove default load balancer (Traefik), if it interferes with required ports:
kubectl delete svc traefik -n kube-system
kubectl delete deployment traefik -n kube-system

2. Connect Kubernetes Cluster to Azure Arc

Register your K3s cluster with Azure Arc, enabling management from Azure. Follow the official documentation for step-by-step guidance.

3. Configure Azure Container Apps Extension and Environment

Set up the Azure Container Apps extension for your cluster. (CoreDNS customizations for Azure Local can be skipped in this setup.)

4. Configure Storage (SQL Server and SMB)

SQL Database: Used by Logic Apps for runtime operations and history logs. The author:
- Set up SQL Server 2022 with SQL authentication on the Windows host.
- Created a dedicated SQL admin user (detailed instructions).
- Connection validation script:
  
```powershell $connectionString = “Server=;Initial Catalog=;Persist Security Info=False;User ID=;Password=;..." try { $connection = New-Object System.Data.SqlClient.SqlConnection $connection.ConnectionString = $connectionString $connection.Open() Write-Host "✅ Connection successful" $connection.Close() } catch { Write-Host "❌ Connection failed: $(--- layout: "post" title: "Deploying Hybrid Azure Logic Apps on K3s for Lightweight, On-Premises Integration" description: "This guide by praveensri explains how to deploy Azure Logic Apps Standard in hybrid mode on a K3s Kubernetes cluster, enabling integration scenarios close to on-premises data sources.

SMB File Share: Handles local artifact storage.

Create a local Windows user for the SMB share:

$Username = "k3suser"
$Password = ConvertTo-SecureString "<password>" -AsPlainText -Force
$FullName = "K3s user"
$Description = "Created via PowerShell"
New-LocalUser -Name $Username -Password $Password -FullName $FullName -Description $Description
Add-LocalGroupMember -Group "Users" -Member $Username

Set up the shared folder with the appropriate permissions (detailed steps).

5. Create Hybrid Logic Apps (Standard)

Use the Azure Portal to create Logic Apps Standard workflows.
Configure the app to use your SQL connection and SMB path.
Use the designer to develop and deploy workflows. Hybrid Logic Apps now run on your K3s cluster, accessing local data securely and efficiently.

Additional Notes

Most of the process aligns with Microsoft’s official documentation, except for the lightweight K3s specifics.
This deployment strategy is beneficial for organizations seeking to modernize integration (e.g., BizTalk migration), ensuring flexibility, cost-effectiveness, and alignment with edge computing needs.
