Issue & Reproduction Steps

Expected behavior: The Node executor image includes a script that can receive input files over stdin and return output files over stdout.

Actual behavior: The image only includes run.sh, which runs the script when input files are already present on disk.

Solution

• Add src/run-stream.sh, which:
  • Extracts a tar archive from stdin into the container (tar xf - -C /)
  • Runs the existing executor via /bin/sh /opt/executor/run.sh
  • If output paths are passed as arguments, streams them back as a tar archive on stdout (tar cf - -C / "$@")

How to Test

1. Rebuild the Node Script Executor Docker image so it includes run-stream.sh.
2. Create a tar archive with the required executor files (e.g. opt/executor/data.json, opt/executor/config.json, opt/executor/script.js).
3. Run the container with stdin attached and command:
   /bin/sh /opt/executor/run-stream.sh opt/executor/output.json
4. Pipe the input tar into the container and confirm:
   • The script runs without error
   • A tar stream containing output.json is returned on stdout
5. Confirm existing execution via /bin/sh /opt/executor/run.sh still works unchanged.
