Congratulations on starting development! Next steps:
- Write the JSON schema describing your resource, betterstack-betteruptime-heartbeat.json
- Implement your resource handlers in handlers.ts
Don't modify models.ts by hand, any modifications will be overwritten when the
generateorpackagecommands are run.
Implement CloudFormation resource here. Each function must always return a ProgressEvent.
const progress = ProgressEvent.builder<ProgressEvent<ResourceModel>>()
// Required
// Must be one of OperationStatus.InProgress, OperationStatus.Failed, OperationStatus.Success
.status(OperationStatus.InProgress)
// Required on SUCCESS (except for LIST where resourceModels is required)
// The current resource model after the operation; instance of ResourceModel class
.resourceModel(model)
.resourceModels(null)
// Required on FAILED
// Customer-facing message, displayed in e.g. CloudFormation stack events
.message('')
// Required on FAILED a HandlerErrorCode
.errorCode(HandlerErrorCode.InternalFailure)
// Optional
// Use to store any state between re-invocation via IN_PROGRESS
.callbackContext({})
// Required on IN_PROGRESS
// The number of seconds to delay before re-invocation
.callbackDelaySeconds(0)
.build()While importing the @amazon-web-services-cloudformation/cloudformation-cli-typescript-lib library, failures can be passed back to CloudFormation by either raising an exception from exceptions, or setting the ProgressEvent's status to OperationStatus.Failed and errorCode to one of HandlerErrorCode. There is a static helper function, ProgressEvent.failed, for this common case.
Keep in mind, during runtime all logs will be delivered to CloudWatch if you use the log() method from LoggerProxy class.
