This is just small project to write simple API to upload files to specific Azure Storage account and Container. For this purpose simple Web Form will be used. This WebForm consist of Browse and Upload botton. You just need to pick up file from your drive and it will simply upload it to predefined Storage in Azure.

At the end it will provide you new SAS URI which can be shared. URI has limited validity (1 Day).

Possible usecase You could run this GO binary in container. It can be used temporarily with random storage account. Quickly upload large files (Max size: 512MB) and share these generated links with vendor, customer or internally. Also customers, vendors or someone can use this way to easily and securely upload some data, which will be then available for you.

upload_page.html is a template page which is used in Go code to render HTML with CSS styles.
