S3 Screen

  2 minute read.

Last Modified 2023-05-26 11:36 EDT

S3 manages data using object storage architecture.

Having large numbers of files (>100K for instance) in a single bucket with no sub-directories is not recommended. It can harm performance and cause stability issues.

Use the S3 screen to configure S3 on your TrueNAS.


The SAVE button activates after entering the required settings.

CANCEL closes the S3 screen without saving changes and displays the Services screen.

S3 Configuration Options

MinIO deprecated Access key and Secret key. MINIO_ROOT USER arguments and their values replace Access key. MINIO_ROOT_PASSWORD arguments and their values replace Secret key. For the ROOT_USER value, use a name up to 20 characters. For the ROOT_PASSWORD, use a string of 8 to 40 randomized characters. MinIO recommends using a long password string of unique random characters.
