Settings Overview on SILO

Core Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers settings that control core behavior of the MinIO process.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

Root Access Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers settings that control root (superuser) access for the MinIO process. The root user has complete access and permissions to perform operations on the MinIO deployment.

Root User and Root Password are required even if you use the MinIO Key Encryption Service or other key management utility.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

Erasure Code Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers settings that configure the Erasure Code parity to use for objects written to the MinIO cluster. This impacts how MinIO uses the space on the drive(s) and how MinIO can recover objects stored on lost drives or similar issues.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

MinIO Console Settings

Mon, 01 Jan 0001 00:00:00 +0000

Changed: RELEASE.2025-05-24T17-08-30Z

The Console now presents only object browser capabilities similar to those available through the mc tool. For administrative interactions, such as user management, use the mc admin command.

Some of the settings on this page may no longer be relevant for newer deployments.

This page covers settings that manage access and behavior for the MinIO Console.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

Metrics and Logging Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers settings that control behavior related to MinIO metrics and logging. See Metrics and alerts for more information.

These settings configure publishing regular minio server logs and audit logs to an HTTP webhook. See Publish Server or Audit Logs to an External Service for more complete documentation.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

ILM Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers settings that control Information Lifecycle Management (ILM) for the MinIO process.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

Key Encryption Service Settings

Mon, 01 Jan 0001 00:00:00 +0000

MinIO Server includes three groups of environment variables to manage how the MinIO Server interacts with the Key Encryption Service (KES), Key Management Service (KMS), or static key files. You may only define one of the three sets. If more than one type of environment variable sets is defined, MinIO returns an error.

Note

These settings do not have configuration setting options for use with mc admin config set.

Object Lambda function settings

Mon, 01 Jan 0001 00:00:00 +0000

This page describes the settings available to configure MinIO to publish data to an HTTP webhook endpoint and trigger an Object Lambda function. See Transforms with Object Lambda for more complete documentation and tutorials on using these settings.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.

Deprecated Settings

Mon, 01 Jan 0001 00:00:00 +0000

This page covers deprecated settings that control core behavior of the MinIO process.

Settings on this page may be removed at any time. Users should migrate to the recommended replacement at the earliest opportunity.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO 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, MinIO uses the environment variable value.
