# Configuration

Fluent Bit is flexible enough to be configured either from the command line or through a configuration file. For production environments, we strongly recommend to use the configuration file approach.

Note that all configuration files uses a specific fixed and strict schema, please proceed to the following sections for a better understanding:

* [File Schema](/manual/1.0/configuration/schema.md) (must read)
* [Configuration Files](/manual/1.0/configuration/file.md)
* [Configuration Variables](/manual/1.0/configuration/variables.md)
* [Configuration Commands](/manual/1.0/configuration/commands.md)
* [Monitoring](/manual/1.0/configuration/monitoring.md)
* [Unit Sizes](/manual/1.0/configuration/unit_sizes.md)
* [TLS / SSL](/manual/1.0/configuration/tls_ssl.md)
* [Backpressure](/manual/1.0/configuration/backpressure.md)
* [Memory Usage](/manual/1.0/configuration/memory_usage.md)
