AWS Incident Manager On-call Calendar Generator

AWS Lambda function that generates an on-call schedule that calendar apps can subscribe to. For more details, see the DoltHub blog post.

To run in AWS Lambda, make sure:

• your Lambda execution role has permission to call ssm-contacts:ListRotationShifts
• you populate the ROTATION_ID_ARN environment variable in your Lambda function's environment with the ARN of the AWS Incident Manager rotation for which you want to generate a calendar.

To test locally, see the Test_GenerateCalendar function in main_test.go and make sure:

• you populate the ONCALL_CALENDAR_GENERATOR_ASSUMED_ROLE environment variable with the role you need to assume in order to access. For DoltHub developers, this should be the ARN of the LiquidataDeveloper role.
• you may need to alter the initializeLocalClient code in order to load the correct AWS credentials for your environment.
• you populate the ROTATION_ID_ARN environment variable in your test process' environment with the ARN of the AWS Incident Manager rotation for which you want to generate a calendar.
