Beginner’s Tutorial: Manage Azure Storage Account Container & Blob with n8n

> This beginner-friendly n8n workflow shows you how to generate AI images using OpenAI, store them in Azure Blob Storage, and manage blob containers, all with zero code.

👤 Who’s it for

This workflow is perfect for:

• Beginners learning Azure + OpenAI integration
• No-code developers experimenting with image generation
• Cloud learners who want hands-on Blob Storage use cases
• Anyone who wants to automate storing AI-generated content in the cloud

⚙️ How it works / What it does

1. 🖱️ Trigger the workflow manually using the Execute Workflow node.
2. ✏️ Use the Edit Fields node to input:
   • containerName (e.g., demo-images)
   • imageIdea (e.g., "a robot holding a coffee cup")
3. 📦 Create a new Azure Blob container (Create container).
4. 🤖 Use an OpenAI-powered Prompt Generation Agent to craft the perfect image prompt.
5. 🎨 Generate an image using OpenAI’s DALL·E model.
6. ☁️ Upload the generated image to Azure Blob Storage (Create Blob).
7. 📂 List blobs in the container (Get many blobs).
8. 🧹 Delete any blob as needed (Delete Blob).
9. (Optional) 🗑️ Remove the entire container (Delete container).

🔧 How to set up

1. 🧠 Set up OpenAI

   • Create an OpenAI account and get your API key.
   • In n8n, go to Credentials → OpenAI and paste your key.

2. 🪣 Set up Azure Blob Storage

   • Log in to your Azure Portal.
   • Create a Storage Account (e.g., mystorageaccount).
   • Go to Access Keys tab and copy:
     • Storage Account Name
     • Key1
   • In n8n, create a new Azure Blob Storage Credential using:
     • Account Name = your storage account name
     • Access Key = key1 value

   > 📝 This demo uses Access Key authentication. You can also configure Shared Access Signatures (SAS) or OAuth in production setups.

3. Run the Workflow

   • Enter your image idea and container name.
   • Click “Execute Workflow” to test it.
