Arcaflow Scenarios using Krkn

Usage

To enable arcaflow scenarios edit the kraken config file, go to the section kraken -> chaos_scenarios of the yaml structure and add a new element to the list named arcaflow_scenarios then add the desired scenario pointing to the input.yaml file.

kraken:
    ...
    chaos_scenarios:
        - arcaflow_scenarios:
            - scenarios/arcaflow/cpu-hog/input.yaml

input.yaml

The implemented scenarios can be found in scenarios/arcaflow/<scenario_name> folder. The entrypoint of each scenario is the input.yaml file. In this file there are all the options to set up the scenario accordingly to the desired target

config.yaml

The arcaflow config file. Here you can set the arcaflow deployer and the arcaflow log level. The supported deployers are:

• Docker
• Podman (podman daemon not needed, suggested option)
• Kubernetes

The supported log levels are:

• debug
• info
• warning
• error

workflow.yaml

This file contains the steps that will be executed to perform the scenario against the target. Each step is represented by a container that will be executed from the deployer and its options. Note that we provide the scenarios as a template, but they can be manipulated to define more complex workflows. To have more details regarding the arcaflow workflows architecture and syntax it is suggested to refer to the Arcaflow Documentation.
