Configuration YAML file

Assemblyline 4 configuration is done using a YAML file (config.yml) which is deployed to all containers when they are launched.

Specification and defaults

The full specification of the file is defined here. The Object Data Model (ODM) converts the python model to a YAML file which looks like the following by default:

Layers of the configuration file

The configuration file is built in layers:

1. The ODM converts the python classes to the default values as shown above
2. The default assemblyline helm chart values.yaml file changes certain of these values to adapt them to a Kubernetes deployment
3. Your deployment's values.yaml file change the values to their final form

Changing the configuration file

If you want to change the config.yml file that will be deployed in the containers, it will have to be done through the configuration section found in the values.yml file of your deployment.

Example

Let's say that you would want to change the log level in the system to ERROR an up.

First of you would edit the values.yaml file of your personal deployment to add the changes to the configuration section:

...
configuration:
  logging:
    log_level: ERROR
...

Then you would simply deploy that new values.yaml file using the helm upgrade command specific to your deployment:

• Cluster deployment update
• Appliance deployment update
