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

Watch the video

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.
