Azure Blob Storage Component

Manage files and folders within Azure Blob Storage

Component key: azure-blob

Description

Azure Blob Storage is a cloud solution for storing unstructured data, like large binary or text files. It's often used to store blob data for web applications that don't store nicely in a relational database.

This component allows you to list, create and delete Azure containers, and create and modify blobs (files) within those Azure containers.

Information about Azure Blob Storage can be found on their documentation site.

Azure Blob Storage Connections

Connection String

You can also grant limited access to your Azure Storage Resources using Shared Access Signatures (SAS) authentication, which involves an access token. You can obtain a connection string containing an SAS token from the Azure Portal. Keep in mind this token will eventually expire. Make sure to configure an expiration date you will remember, so you can manually refresh the token at a later date.

Input	Notes	Example
Input Connection String string / Required	Notes Provide the connection string for your active directory account.	Example BlobEndpoint=https://example.blob.core.windows.net/;QueueEndpoint=https://example.queue.core.windows.net/;FileEndpoint=https://example.file.core.windows.net/;TableEndpoint=https://example.table.core.windows.net/;SharedAccessSignature=sv=example=rwdlacupitfx&se=2024-05-01T03:51:00Z&st=20

Storage Shared Key

Azure Blob can use storageSharedKeyCredential authentication, which involves an account / key pair. You can obtain an account name / account key pair through the Azure Portal.

Input	Notes	Example
Input Account Key string / Required	Notes Provide the key for your active directory account.	Example exampleKey
Input Account Name string / Required	Notes Provide the name for your active directory account.	Example exampleName
