Bicep resource definition

The experiments resource type can be deployed with operations that target:

• Resource groups - See resource group deployment commands

For a list of changed properties in each API version, see change log.

Resource format

To create a Microsoft.Chaos/experiments resource, add the following Bicep to your template.
