Overview ¶
Package awsrunner hosts and invokes the Celerity maintenance runner on AWS.
The runner is a Lambda function in the database's private subnets. Both halves of the AWS-specific story live here, and both register themselves on import: a Host, which delivers Lambda invocations to the cloud-neutral executor, and an Invoker, which the CLI calls it through. Importing this package is the only thing that ties either binary to AWS.
lambda:Invoke is what makes this work. It is a control-plane call, so it reaches a function in a private subnet from an operator's machine with no network path to the VPC at all, and the same credentials that just ran the deploy are enough.
