Including Amazon EventBridge resources in Amazon CloudFormation stacks

Amazon CloudFormation enables you to configure and manage your Amazon resources across accounts and regions in a centralized and repeatable manner by treating infrastructure as code. CloudFormation does this by letting you create templates, which define the resources you want to provision and manage. These resources can include EventBridge artifacts such as event buses and rules, pipes, schemas, and schedules, among others. Use these resources to include EventBridge functionality in the technology stacks you provision and manage through CloudFormation.

EventBridge provides resources for use in CloudFormation templates in the following resource namespaces:

As an aid to help you jumpstart developing CloudFormation templates, the EventBridge console enables you to create CloudFormation templates from the existing event buses, rules, and pipes in your account.

Because EventBridge provisions the default event bus into your account automatically, you cannot create it using a CloudFormation template, as you normally would for any resource you wanted to include in a CloudFormation stack. To include the default event bus in a CloudFormation stack, you must first import it into a stack. Once you have imported the default event bus into a stack, you can then update the event bus properties as desired.

Beyond including EventBridge resources in your CloudFormation stacks, you can use EventBridge to manage the events generated by CloudFormation stacks themselves. CloudFormation sends events to EventBridge whenever a create, update, delete, or drift-detection operation is performed on a stack. CloudFormation also sends events to EventBridge for status changes to stack sets and stack set instances. You can use EventBridge rules to route events to your defined targets.
