How to get on-prem IS to upload a file into Azure 'Blob' storage

3

Progress (well, got it compiling at least)!

Initially, I’d downloaded azure-storage-blob-12.14.2.jar. Later, I found its webpage lists four additional JAR package as dependencies. I downloaded these into the /code/jars folder and reloaded the package:

azure-core-1.22.0.jar 
azure-core-http-netty-1.11.2.jar 
azure-storage-common-12.14.1.jar  
azure-storage-internal-avro-12.1.2.jar

…then kept fixing compile errors until I got this code to compile:

import com.azure.storage.blob.models.*;
import com.azure.storage.*;
import com.azure.storage.common.*;
import com.azure.core.exception.*;

...

		/* Create a new BlobServiceClient with a Shared Key */
		BlobServiceClient blobServiceClient = new BlobServiceClientBuilder()
		    .endpoint("https://<storage-account-name>.blob.core.windows.net")
		    .credential (new StorageSharedKeyCredential("<accountName>", "<accountKey>") )
		    .buildClient();    
		 
		BlobContainerClient containerClient =null;  
		/* Create a new container client */
		try {
		    containerClient = blobServiceClient.createBlobContainer("<container-name>");
		} catch (BlobStorageException ex) {
		    // The container may already exist, so don't throw an error
		    if (!ex.getErrorCode().equals(BlobErrorCode.CONTAINER_ALREADY_EXISTS)) {
		        throw ex;
		    }
		}
		
		/* Upload the file to the container */
		BlobClient blobClient = containerClient.getBlobClient("file.csv");
		blobClient.uploadFromFile("file.csv");

Next week I plan to progress further. One essential change I need is to make blobClient accept a stream as input.
