Settings Overview

MinIO Settings

MinIO settings define runtime behavior of the MinIO server 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.

• a configuration setting using the MinIO Console’s Administrator > Settings pages.

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

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

Additional settings include those to customize:

• Core settings

• Root credentials

• Storage class

• MinIO Console

• Metrics and logging

• Notification targets for use with MinIO Bucket Notifications

• Identity and access management solutions

• Key Encryption Service (KES)

• Object Lambda functions
