Automatically Delete/Expire Azure Blobs after a time period

It is possible with the Azure Blob storage lifecycle. Please take a look here

https://docs.microsoft.com/en-us/azure/storage/blobs/storage-lifecycle-management-concepts?tabs=azure-portal

Because I've missed the feature for years I wrote a small project with a nice 'Deploy to Azure button'. Not yet perfect but works https://github.com/nulllogicone/ExpireBlobFunction

And now I see that Microsoft has released this as a feature on March 27, 2019.

Excerpt from that article:

Azure Blob storage lifecycle management offers a rich, rule-based policy for GPv2 and Blob storage accounts. Use the policy to transition your data to the appropriate access tiers or expire at the end of the data's lifecycle.

The lifecycle management policy lets you:

• Transition blobs to a cooler storage tier (hot to cool, hot to archive, or cool to archive) to optimize for performance and cost
• Delete blobs at the end of their lifecycles
• Define rules to be run once per day at the storage account level Apply rules to containers or a subset of blobs (using prefixes as filters)
