# Config Loaders

Config loaders allow for the configuration on the Imagizer instance upon startup.


Config loaders will override all previously made Imagizer configurations on boot.


All configurations are persistent. Even after the config loader is removed and the instance is rebooted.


AWS EC2 allows for information to be passed through using User Data (opens new window).

Add valid Imagizer JSON configuration directly into the EC2 User Data. The EC2 instance will automatically configure itself using the User Data configuration on startup.

# Example

# On-Premise

Imagizer On-Premise images come built with Cloud-init, which may be used to configure Imagizer. Please see the On-Premise Guide.
