Settings and Configurations

The AIStor Server process stores its configuration in the storage backend directory. These settings define runtime behavior of the AIStor Server process.

You can establish or modify settings by defining:

  • an environment variable on the host system prior to starting or restarting the AIStor Server. Refer to your operating system’s documentation for how to define an environment variable.
  • a configuration setting using mc admin config set.

If you define both an environment variable and the similar configuration setting, AIStor uses the environment variable value.

Some settings have only an environment variable or a configuration setting, but not both.

Each configuration setting controls fundamental MinIO behavior and functionality. Test configuration changes in a lower environment, such as DEV or QA, before applying to production.

Additional settings

Additional settings include those to customize:

File-based environment variables

Environment variables with a _FILE suffix accept a file path as their value. AIStor reads the value from the specified file at startup. For example, MINIO_ROOT_USER_FILE=/run/secrets/root_user directs AIStor to read the root user credential from the file at that path.

When both a standard environment variable and its _FILE equivalent are defined, AIStor uses the standard environment variable value and ignores the file-based variable.

The following environment variables support the _FILE suffix pattern:
