Scheduled Function on AWS

View Code

A simple function in AWS that executes based on a schedule using CloudWatch.

In this example, an S3 Bucket will be created. A function will run every Friday at 11:00pm UTC that will delete all of the objects it contains.

Deploying and running the program

1. Create a new stack:

   $ pulumi stack init dev

2. Set the AWS region:

   $ pulumi config set aws:region us-east-1
   

3. Restore NPM modules via npm install or yarn install.

4. Run pulumi up to preview and deploy changes:

   ``` $ pulumi up Previewing update of stack ‘dev’ …

   Updating (dev):

   Type                                          Name                           Status
   

   • pulumi:pulumi:Stack aws-ts-scheduled-function-dev created
   • ├─ aws:cloudwatch:EventRuleEventSubscription emptyTrash created
   • │ ├─ aws:cloudwatch:EventRule emptyTrash created
   • │ ├─ aws:iam:Role emptyTrash created

   • │ ├─ aws:cloudwatch:EventTarget emptyTrash created
   • │ └─ aws:lambda:Permission emptyTrash created
   • └─ aws:s3:Bucket trash created

   Outputs: bucketName: “trash-28693b6”

   Resources: + 9 created

   Duration: 16s ```

Clean up

1. Run pulumi destroy to tear down all resources.

2. To delete the stack itself, run pulumi stack rm. Note that this command deletes all deployment history from the Pulumi Console.
