OpenWebUI on Azure Container Apps

Terraform configuration to deploy OpenWebUI on Azure Container Apps with persistent storage.

ℹ️ This is a Terraform implementation of the guide: Deploy OpenWebUI on Azure Container Apps (which uses Azure Portal)

Key Configuration

• Scaling: Fixed to 1 replica (required for stability)

  min_replicas = 1
  max_replicas = 1

• Storage: Azure File Share with required mount options

  mount_options = "nobrl"  # Required for proper file locking

Prerequisites

• Azure CLI (install)
• Terraform >= 1.0.0
• Azure subscription

Quick Start

1. Clone and enter the repository:

   git clone https://github.com/yourusername/azure-openwebui-infra.git

2. Configure your Azure credentials:

   az login

3. Initialize Terraform:

   terraform init

4. Deploy:

Important Notes

• The application requires exactly 1 replica for stable operation
• Persistent storage uses Azure File Share with nobrl mount option for compatibility
• Default configuration includes HTTPS with Let's Encrypt

Configuration

Customize your deployment by editing these variables in variables.tf or creating a terraform.tfvars file:

location = "northeurope"          # Azure region
container_app_name = "openwebui"  # Name for your container app
container_image = "ghcr.io/open-webui/open-webui:main"  # Version to deploy

Key configuration options:

• location: Azure region (default: "northeurope")
• resource_group_name: Name for the resource group
