Jobs View Cancel

The Jobs list is the home screen of the platform. It displays all scenario executions for your group, with real-time status updates and access to logs and results.

Run Types

Single Run

A single scenario execution on one or more target clusters. For each run you can inspect:

Cluster Terminal

Mon, 01 Jan 0001 00:00:00 +0000

Cluster Terminal Run

A built-in terminal for exploring target clusters using read-only oc and kubectl commands. Useful for inspecting cluster state before, during or after chaos experiments.

Details

Read-only: only read commands are available — no modifications to the cluster are possible
Supported commands: oc and kubectl
Target selection: only clusters accessible to your group are available
Requires Run permission

Run Scenarios

Mon, 01 Jan 0001 00:00:00 +0000

Run Scenarios Run

Execute a chaos scenario on one or more target clusters through a guided step-by-step wizard. All scenarios can run simultaneously across multiple clusters.

Execution Flow

1. Select Target Clusters

Choose one or more clusters to run the scenario on. All selected clusters execute the scenario simultaneously.

Chaos Studio

Mon, 01 Jan 0001 00:00:00 +0000

Chaos Studio Run

A visual drag-and-drop editor for designing complex chaos workflows. Build graphs of scenarios that execute in series or parallel, and measure application resilience with the Resiliency Score.

Creating and Saving Workflows

Creating a New Workflow

Navigate to Chaos Studio from the main navigation
Click the “New Workflow” button to start a blank canvas
Give your workflow a meaningful name that describes its purpose

Adding Nodes

Click the “Add Node” button or drag from the node palette
Position nodes on the canvas by dragging them
Configure each node by clicking on it and selecting:
- Registry: Choose your scenario source
- Scenario: Select the chaos scenario to run
- Parameters: Set mandatory and optional parameters
- Cloud credential: Optionally load a saved cloud credential for cloud-dependent scenarios
- Files: Mount any required configuration files

Connecting Nodes

Click and drag from a node’s output port to another node’s input port to create dependencies
Serial execution: connect nodes in a chain (A → B → C)
Parallel execution: connect one node to multiple targets (A → B and A → C)

Saving Your Workflow

Click the “Save” button in the top toolbar
The workflow is automatically saved to your workspace
Saved workflows appear in the Chaos Studio workflow list
You can edit saved workflows by selecting them from the list

Video Walkthrough

Your browser does not support the video tag.

Visual Editor

Nodes represent individual krkn scenarios
Arrows define execution order — connect nodes to create dependencies
Serial execution: chain nodes sequentially with single arrows
Parallel execution: branch from one node to multiple targets
Drag and drop to arrange the workflow visually

Node Configuration

Each node is configured exactly like a single scenario: select a registry, choose a scenario, set mandatory/optional/global parameters, optionally load a cloud credential, and mount files.

File Management

Mon, 01 Jan 0001 00:00:00 +0000

File Management

Upload and manage text-based configuration files that can be used across scenario executions and Chaos Studio workflows.

This walkthrough is retained with v1.0.0 documentation and may show an earlier interface.

Uploading Files

Files are created by pasting content into the text input box — there is no file upload button.

Constraint	Detail
Formats	JSON, YAML (text only)
Input method	Copy-paste into the text box
Metadata	Name, description, category
Visibility	Everyone or assigned to specific groups

Where Files Are Used

Context	Purpose
Run Scenarios	Mount as configuration file during scenario parameter setup
Chaos Studio	Mount as configuration file on individual nodes
Chaos Studio — Resiliency Score	Mount as PromQL query file for resiliency score calculation
