Worker container shutdown

Your task

Run a Node worker in a container. The worker processes jobs after startup and cleans up the current job when a shutdown request arrives. What to do: complete Dockerfile and the run command. Note: the app entry file is src/worker.js.

Ground rules

•Include only app files and dependencies.
•Do not introduce a separate process manager.

Not required

•Real queue server integration.
•Kubernetes manifests.

▶About this challenge

Review how a job-processing process finishes or cleans up work when the runtime requests shutdown.

In deployment environments, processes can be stopped at any time, so shutdown and cleanup behavior must be explicit.

What does this practice?: It practices shutdown handling and cleanup flow for a worker process.
Which code matters?: Review the job loop together with the code that runs when stopping.
