> When the {{force}} argument is not set to {{true}}, {{Docker::pull}} will always perform a {{docker inspect}} call before it does a {{docker pull}}. If either of these two Docker CLI calls hangs indefinitely, the Docker container will be stuck in the PULLING state. This means that we make no further progress in the {{launch()}} call path, so the executor binary is never executed, the {{Future}} associated with the {{launch()}} call is never failed or satisfied, and {{wait()}} is never called on the container. The agent chains the executor cleanup onto that {{wait()}} call which is never made. So, when the executor registration timeout elapses, {{containerizer->destroy()}} is called on the executor container, but the rest of the executor cleanup is never performed, and no terminal task status update is sent.
> This leaves the task destined for that Docker executor stuck in TASK_STAGING from the framework's perspective, and attempts to kill the task will fail.
