Storage Location

The default storage driver url is file:///tmp/mediorum/blobs. This is the directory on your node where files will stored post transcoding.

To update the local storage location set the AUDIUS_STORAGE_DRIVER_URL environment variable

AUDIUS_STORAGE_DRIVER_URL="file:///my/directory"

The driver is determined based on the storage_url (eg s3://your-bucket uses the s3 driver)

💡 Note: URLs beginning with https:// will default to s3

Cloud Storage

To use cloud object storage instead of local storage, you will need to:

• create either an s3 bucket, gcs bucket or azure storage container
• your bucket access policy should NOT BE PUBLIC
• provision credentials that allow object storage access

S3 storage

AWS_ACCESS_KEY_ID="<my-access-key-id>"
AWS_SECRET_ACCESS_KEY="<my-secret-access-key>"
AWS_REGION="<my-aws-region>"
AUDIUS_STORAGE_DRIVER_URL="s3://my-bucket?region=us-west-1"

GCS storage

GOOGLE_APPLICATION_CREDENTIALS="/path/to/creds.json"
AUDIUS_STORAGE_DRIVER_URL="gs://my-bucket"

Azure storage

AZURE_STORAGE_ACCOUNT="<storage-account-name>"
AZURE_STORAGE_KEY="<storage-key>"
AUDIUS_STORAGE_DRIVER_URL="azblob://my-container"
