+# 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 docker/Backend.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 **Container App** in the [Azure Portal](https://portal.azure.com/#home).
+- In the left menu, select **Containers**.
+- Under your container, update:
+
+    - Image source → Azure Container Registry / Docker Hub.
+
+    - Image name → myapp/backend.
+
+    - Tag → change to the new one you pushed (e.g., v2).
+
+- Click **Save** → this will create a new revision automatically with the updated image.
+
+![alt text](./images/ContainerApp.png)
+
+**WebApp :**
+
+```bash
+az acr login --name <containerregname>
+docker build --no-cache -f docker/Frontend.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 Container 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.
+
+![alt text](./images/AppServiceContainer.png)
+
+
+## ✅ 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.

+<details>
+<summary><b>FlagMustBeSetForRestore/NameUnavailable/CustomDomainInUse</b></summary>
+
+- This error occurs when you try to deploy a Cognitive Services resource that was **soft-deleted** earlier.  
+- Azure requires you to explicitly set the **`restore` flag** to `true` if you want to recover the soft-deleted resource.  
+- If you don’t want to restore the resource, you must **purge the deleted resource** first before redeploying.
+Example causes:
+- Trying to redeploy a Cognitive Services account with the same name as a previously deleted one.  
+- The deleted resource still exists in a **soft-delete retention state**.  
+**How to fix:**
+1. If you want to restore → add `"restore": true` in your template properties.  
+2. If you want a fresh deployment → purge the resource using:  
+   ```bash
+   az cognitiveservices account purge \
+     --name <resource-name> \
+     --resource-group <resource-group> \
+     --location <location>
+    ```

+</details>
+
+<details>
+<summary><b>PrincipalNotFound</b></summary>
+
+- This error occurs when the **principal ID** (Service Principal, User, or Group) specified in a role assignment or deployment does not exist in the Azure Active Directory tenant.  
+- It can also happen due to **replication delays** right after creating a new principal.  
+**Example causes:**
+- The specified **Object ID** is invalid or belongs to another tenant.  
+- The principal was recently created but Azure AD has not yet replicated it.  
+- Attempting to assign a role to a non-existing or deleted Service Principal/User/Group.  
+**How to fix:**
+1. Verify that the **principal ID is correct** and exists in the same directory/tenant.  
+   ```bash
+   az ad sp show --id <object-id>
+    ```
+2. If the principal was just created, wait a few minutes and retry.
+3. Explicitly set the principalType property (ServicePrincipal, User, or Group) in your ARM/Bicep template to avoid replication delays.
+4. If the principal does not exist, create it again before assigning roles.
+For more details, see [Azure PrincipalType documentation](https://learn.microsoft.com/en-us/azure/role-based-access-control/troubleshooting?tabs=bicep)
+</details>
+<details>
+<summary><b>RedundancyConfigurationNotAvailableInRegion</b></summary>
+
+- This issue happens when you try to create a **Storage Account** with a redundancy configuration (e.g., `Standard_GRS`) that is **not supported in the selected Azure region**.
+- Example: Creating a storage account with **GRS** in **italynorth** will fail with this error.
+```bash
+az storage account create -n mystorageacct123 -g myResourceGroup -l italynorth --sku Standard_GRS --kind StorageV2
+```
+- To check supported SKUs for your region:
+```bash
+az storage account list-skus -l italynorth -o table
+```
+Use a supported redundancy option (e.g., Standard_LRS) in the same region
+Or deploy the Storage Account in a region that supports your chosen redundancy.
+For more details, refer to [Azure Storage redundancy documentation](https://learn.microsoft.com/en-us/azure/storage/common/storage-redundancy?utm_source=chatgpt.com).
+</details>
+
+<details> <summary><b>DeploymentNotFound</b></summary>
+
+- This issue occurs when the user deletes a previous deployment along with the resource group (RG), and then redeploys the same RG with the same environment name but in a different location.
+
+- To avoid the DeploymentNotFound error, Do not change the location when redeploying a deleted RG, or Use new names for the RG and environment during redeployment.
+</details>
+
+<details><summary><b>DeploymentCanceled(user.canceled)</b></summary>
+
+- Indicates the deployment was manually canceled by the user (Portal, CLI, or pipeline).
+
+- Check deployment history and logs to confirm who/when it was canceled.
+
+- If accidental, retry the deployment.
+
+- For pipelines, ensure no automation or timeout is triggering cancellation.
+
+- Use deployment locks or retry logic to prevent accidental cancellations.
+
+</details>
+
+<details><summary><b>ResourceGroupDeletionTimeout</b></summary>
+
+- Some resources in the resource group may be stuck deleting or have dependencies; check RG resources and status.
+
+- Ensure no resource locks or Azure Policies are blocking deletion.
+
+- Retry deletion via CLI/PowerShell `(az group delete --name <RG_NAME> --yes --no-wait)`.
+
+- Check Activity Log to identify failing resources; escalate to Azure Support if deletion is stuck.
+
+</details>
+
+<details>
+<summary><b>SubscriptionDoesNotHaveServer</b></summary>
+
+- This issue happens when you try to reference an **Azure SQL Server** (`Microsoft.Sql/servers`) that does not exist in the selected subscription.  
+- It can occur if:  
+  - The SQL server name is typed incorrectly.  
+  - The SQL server was **deleted** but is still being referenced.  
+  - You are working in the **wrong subscription context**.  
+  - The server exists in a **different subscription/tenant** where you don’t have access.
+
+**Reproduce:**  
+1. Run an Azure CLI command with a non-existent server name:
+```bash
+   az sql db list --server sql-doesnotexist --resource-group myResourceGroup
+```
+
+  or
+
+```bash
+  az sql server show --name sql-caqfrhxr4i3hyj --resource-group myResourceGroup
+
+```
+
+Resolution:
+
+Verify the SQL Server name exists in your subscription:
+
+```bash
+    az sql server list --output table
+```
+Make sure you are targeting the correct subscription:
+
+```bash
+    az account show
+    az account set --subscription <subscription-id>
+```
+If the server was deleted, either restore it (if possible) or update references to use a valid existing server.
+
+</details>
+
+
+<details><summary><b>BadRequest - DatabaseAccount is in a failed provisioning state because the previous attempt to create it was not successful</b></summary>
+
+- This error occurs when a user attempts to redeploy a resource that previously failed to provision.
+
+- To resolve the issue, delete the failed deployment first, then start a new deployment.
+
+- For guidance on deleting a resource from a Resource Group, refer to the following link: [Delete an Azure Cosmos DB account](https://learn.microsoft.com/en-us/azure/cosmos-db/nosql/manage-with-powershell#delete-account:~:text=%3A%24enableMultiMaster-,Delete%20an%20Azure%20Cosmos%20DB%20account,-This%20command%20deletes)
+
+</details>
+
+<details>
+
+<summary><b>SpecialFeatureOrQuotaIdRequired</b></summary>
+
+This error occurs when your subscription does not have access to certain Azure OpenAI models.  
+
+**Example error message:**  
+`SpecialFeatureOrQuotaIdRequired: The current subscription does not have access to this model 'Format:OpenAI,Name:o3,Version:2025-04-16'.`  
+
+**Resolution:**  
+To gain access, submit a request using the official form:  
+👉 [Azure OpenAI Model Access Request](https://customervoice.microsoft.com/Pages/ResponsePage.aspx?id=v4j5cvGGr0GRqy180BHbR7en2Ais5pxKtso_Pz4b1_xUQ1VGQUEzRlBIMVU2UFlHSFpSNkpOR0paRSQlQCN0PWcu)  
+
+You’ll need to use this form if you require access to the following restricted models:  
+- gpt-5
