Settings Overview
The minio server process stores its configuration in the storage backend directory.
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.
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.
Important
Each configuration setting controls fundamental MinIO behavior and functionality. MinIO strongly recommends testing configuration changes in a lower environment, such as DEV or QA, before applying to production.
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
