+# Azure Container Registry (ACR) – Build & Push Guide
+
+This guide provides step-by-step instructions to build and push Docker images for **WebApp** and **Backend** services into Azure Container Registry (ACR).
+
+## 📋 Prerequisites
+Before starting, ensure you have:
+- An active [Azure Subscription](https://portal.azure.com/)
+- [Azure CLI](https://learn.microsoft.com/en-us/cli/azure/install-azure-cli) installed and logged in
+- [Docker Desktop](https://docs.docker.com/get-docker/) installed and running
+- Access to your Azure Container Registry (ACR)
+- To create an Azure Container Registry (ACR), you can refer to the following guides:
+
+    - [Create Container Registry using Azure CLI](https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-azure-cli)
+
+    - [Create Container Registry using Azure Portal](https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-portal?tabs=azure-cli)
+
+    - [Create Container Registry using PowerShell](https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-powershell)
+
+    - [Create Container Registry using ARM Template](https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-geo-replication-template)
+
+    - [Create Container Registry using Bicep](https://learn.microsoft.com/en-us/azure/container-registry/container-registry-get-started-bicep?tabs=CLI)
+
+---
+
+Login to ACR :
+``` bash
+az acr login --name $ACR_NAME
+```
+
+## 🚀 Build and Push Images
+
+**Backend :** 
+ 
+ ```bash 
+az acr login --name <containerregname>
+docker build --no-cache -f api/ApiApp.Dockerfile -t <acrloginserver>/<repo>:<tagname> .
+docker push <acrloginserver>/<repo>:<tagname>
+ ```
+
+If you want to update image tag and image manually you can follow below steps:
+- Go to your api App Service in the [Azure Portal](https://portal.azure.com/#home).
+- In the left menu, select Deployment → Deployment Center
+- Under Registry settings, you can configure:
+
+    - Image Source → (e.g., Azure Container Registry / Docker Hub / Other).
+
+    - Image Name → e.g., myapp/backend.
+
+    - Tag → e.g., v1.2.3.

+
+**WebApp :**
+
+```bash
+az acr login --name <containerregname>
+docker build --no-cache -f App/WebApp.Dockerfile -t <acrloginserver>/<repo>:<tagname> .
+docker push <acrloginserver>/<repo>:<tagname>
+```
+
+If you want to update image tag and image manually you can follow below steps:
+- Go to your App Service in the [Azure Portal](https://portal.azure.com/#home).
+- In the left menu, select Deployment → Deployment Center
+- Under Registry settings, you can configure:
+
+    - Image Source → (e.g., Azure Container Registry / Docker Hub / Other).
+
+    - Image Name → e.g., myapp/backend.
+
+    - Tag → e.g., v1.2.3.

+
+
+## ✅ Verification
+
+Run the following command to verify that images were pushed successfully:
+```bash
+az acr repository list --name $ACR_NAME --output table
+```
+
+You should see repositories in the output.
+
+## 📝 Notes
+
+- Always use meaningful tags (v1.0.0, staging, prod) instead of just latest.
+
+- If you are pushing from a CI/CD pipeline, make sure the pipeline agent has access to Docker and ACR.
+
+- For private images, ensure your services (e.g., Azure Container Apps, AKS, App Service) are configured with appropriate ACR pull permissions.
