The executor service polls the public frontend API for work to perform. The executor will pull a job from a particular queue (configured via the envvar EXECUTOR_QUEUE_NAME), then performs the job by running a sequence of docker and src-cli commands. This service is horizontally scalable.

Since executors and Sourcegraph are separate deployments, our agreement is to support 1 minor version divergence for now. See this example for more details:
