Run a GameDay (V1)

This topic describes how to create and execute a GameDay.


  1. HCE account
  2. Access to a cluster

Plan your GameDay

Address the following questions before proceeding to run a GameDay:

  1. Which services should I test?
  2. What is the goal of the GameDay?
  3. What should I verify or determine by the end of the GameDay?

Once these questions have a viable answer, you can proceed to create a GameDay.

If you are new to HCE, head to GameDay V2 and follow the steps to create and run a GameDay

Creating a GameDay involves two steps:

  1. Specifying details about the GameDay,
  2. Adding chaos experiments to the GameDay.

Create a GameDay

  1. Select +New GameDay.

  2. Add details such as GameDay name, Objectives, and Description (optional). Select Next-> Select Chaos Experiments.

Add experiments to the GameDay

  1. Once you create a GameDay, select New Chaos Experiment to add experiments to the GameDay.

  2. Select one or more experiments that are available in the ChaosHub.

Add infrastructure

  1. Select a chaos infrastructure. Select Add experiments to the GameDay.


    You can add up to 20 experiments to every GameDay, and every chaos experiment can be executed on a different chaos infrastructure.

This opens a page that lists the experiments you selected for the current GameDay. You can add or delete experiments from this page.

Select the experiment to see a preview of the experiment's pipeline.

  1. After adding the experiments to the GameDay, select Save.

Schedule or run the GameDay

Now that you have the experiments in the GameDay, you are all set to schedule or run them.

  1. Select Start GameDay. This creates experiments within your GameDay.

  2. Select GameDay that opens the page that contains the experiments associated with the GameDay.

  3. On this page, you can Run the experiment.

  4. Select Run Experiment. This begins the execution of the experiment.

Record the conclusion and action items

  1. Select Add/View Notes to add a summary of the experiments in the GameDay.

  2. Select Mark Run as Complete to mark a GameDay run as complete. After this action, you will not be able to rerun the experiments inside the GameDay run. This completed run serves as a checkpoint within the GameDay that helps keep track of how the application fared during a specific situation.


Congratulations on scheduling (or running) your first GameDay! Based on the results, you can take steps to improve the resilience of your application.
