Thomas Lavocat ab7fe6558a worker: protect the instance from upgrading ... Before the instance was vulnerable to an OTA update while processing a request. Because there is no way of retriggering a job in Composer, it is better to avoid this situation. The way we are doing it is by setting the `protected` flag onto the instance when a job is being processed. This way the AWS scheduler does hopefully not shutdown the machine at the wrong time. Main caveats of this solution: * Starvation: If a worker keeps accepting new jobs, then it might not be updated. * Inconsistency: There exist a window between the job acceptation and the protection where the worker can be shutdown without having the time to protect itself.		2022-05-10 11:45:29 +02:00
