Azure Blob Storage Permissions and Management

In order for Tempo to authenticate to Azure blob storage, the following is required to access the container.

Storage account
Storage account access key
Storage account management policy

The AZURE_STORAGE_ACCOUNT and AZURE_STORAGE_KEY environment variables can be used instead of setting the credentials in the Tempo configuration file.

The following storage account management policy shows an example of cleaning up files from the container after they have been deleted for a period of time.
