FAQ

• What do I do with cdk.json?

These examples come with a cdk.json that specifies the entry point for the CDK application. Many of the examples will access your AWS account to determine availability zones or AMI IDs, and will save the results of that back to cdk.json under the "context" key.

In a production application, you would check in the changes to cdk.json to ensure you have a repeatable build that doesn't access the network. For these example applications, ignore or unstage the changes.
