Access files on Azure Blob Storage using SaS

[rskelly]

We store our videos on Azure and using them with Biigle works perfectly, so long as they are publicly accessible.

If they're not public, they can be accessed by appending a SAS token to the URL as a query string. Doing this to the filenames in a volume actually seems to work, though the SAS has to be appended to every file in the volume.

Is there any appetite for a feature that would allow a user to configure a query string which would be appended to all files in a volume? This way, if the SAS were changed or expired, it could be updated in one place. A storage disk implementation for this seems like it might be a bit of overkill.

We currently don't have any plans to support a use case like that. But if you are working with Azure, we should talk about adding support for this as storage disk. It should be quite straight forward, as there is a Blob Storage adapter in our filesystem abstraction library already. Would this work for you?

I'm sure it would work, and better to keep things consistent, I guess? We can have a look at it, though time is very limited at the moment.

The main changes are in the config and views (here and here) of the biigle/user-disks module. Also you have to add something like the azure-oss/storage-blob-laravel package as dependency. Then if you are lucky, it could already work. I've added an issue for this feature where you can post updates in case someone on your side starts working on this.

@rskelly Are you already working on this? I could have a look since this would likely benefit another project we are involved in. However, since we don't have Azure here, it would be very helpful if you could set up a small test folder with just an image or something that we could use to connect to and test it in the end. If this is doable could you please send the connection info to daniel@biigle.de.

@dlangenk We aren't working on it (yet), for want of time. I've sent you an email with a couple of links and SASes.

Great. Thanks a lot. I tested locally with an azure emulator and it works, already. Tomorrow I will test with the links from your mail.
