Edit and Update Chaos Experiment

Guide to edit and update chaos experiment

You can edit an existing chaos experiment to update the experiment's metadata, faults, schedule, etc. This section describes three actions:

1. Edit an experiment

2. Update old experiment manifests

3. Bulk update CRON schedules

Edit a Chaos Experiment

1. On the Chaos Experiments page, select the ⋮ icon against the name of the experiment you want to edit and select Edit Experiment.

Update Old Experiment Manifests

When you upgrade the chaos infrastructure, you also need to update the images in the experiment manifest (YAML file) corresponding to the updated chaos infrastructure. The upgraded images should match the images in the Enterprise ChaosHub.

When you create a new experiment, the images in the experiment manifest are configured to match the images in the Enterprise ChaosHub.

What image versions to use?

To determine the latest version of images, navigate to Enterprise Chaos Hub, and search for chaos-go-runner. The value associated with chaos-go-runner in the manifest in Enterprise Chaos Hub is the latest version.

Bulk Update CRON Schedules

You can update multiple CRON-scheduled chaos experiments at once.

One important aspect is that you can bulk update multiple CRON schedules to a single value, that is, the CRON schedules you select to update will all update to a single common value.

You can't map different CRON schedules to their respective values while performing a bulk update. You can:

1. Bulk disable active schedules

2. Bulk enable inactive CRON schedules

3. Bulk stop running experiments

To reschedule/enable/disable a CRON schedule,

1. Go to Chaos Experiments and select the experiments you wish to change.

2. Choose one of the following options:

   1. Reschedule CRON

   2. Enable CRON

   3. Disable CRON

      

      bulk update
3. Based on the option you chose,

   • Reschedule CRON: You can change the schedule of the experiments by changing the values, and click Confirm.

   • Enable CRON or Disable CRON

     • Select one of the options (enable CRON or disable CRON), and click Confirm.

     • You will see a confirmation message on your screen about the updated schedule. Click Close.

NOTE

You can bulk update (reschedule or enable/disable) not more than 20 experiments in one go.
