I want to deploy azure function in java with existing resources

Question

I want to deploy azure function in java configuring existing like I want to use my existing storage account . Every time when I create azure function and deploy it then it creates new storage account. Also need to create output binding with storage blob. But there is not enough documentation which explain in details.

Answer 1

When creating a Function App, a general-purpose Azure Storage account is required and must be either created or linked during setup. This storage account must support Blobs, Queues, and Tables. 

If a storage account isn't visible or available during creation, it's likely that the selected type isn't supported (e.g., premium file-only accounts). Refer to the official documentation for supported types: Azure Functions – Storage Account Requirements 

After the Function App is created, you can still interact with other storage resources by: 

Adding connection strings in App Settings. 

Mounting an Azure File share via the Path Mappings blade (Linux apps only). 

Connecting through code using the Azure SDK (e.g., to access Blob Storage). 

Existing storage accounts can be integrated later, provided they meet the required criteria.

To configure your Azure Function in Java to use an existing storage account and set up blob output binding via the Azure Portal, here are the steps along with the official documentation for reference:

1. Use Existing Storage Account

• Go to your Function App in the Azure Portal.
• Navigate to Configuration under Settings.
• Update the AzureWebJobsStorage setting with the connection string of your existing storage account. App settings reference for Azure Functions

2. Configure Blob Output Binding

• In the Function App, go to Functions > select your function > Integration.
• Add a new Output binding.
• Choose Azure Blob Storage as the type.
• Specify the blob path (e.g., container/output.txt) and select the storage account setting (e.g., AzureWebJobsStorage). Azure Blob Storage Output Binding for Azure Functions Please let me know if you need help
