Job Pre-flight
Some executable (e.g. a script) that will run on the Worker before the job runs. If the pre-flight fails, the job will not run on this Worker, but will be moved to another. Useful for setting up environments, copying required images, checking the existence of fonts on the Worker, etc.
Job Post-flight
An executable that will run on the Worker after the job has finished on that Worker. If this fails, the instance is failed.
Work Pre-flight
Some executable (e.g. a script) that will run on the Worker before the frame/work runs. If this fails, the frame/work is failed. If there are retries configured, the work will be treated according to those settings.
Work Post-flight
Some executable (e.g. a script) that will run on the Worker after the frame/work runs. If this fails, the frame/work is failed. If there are retries configured, the work will be treated according to those settings.
