Manifest

Manifest is the entrypoint for the server. File manifest.json is required for each lambda.

Minimal manifest looks like

{
  "run": ["/bin/sh","./myscript.sh"]
}

where /bin/sh is runner and ./myscript.sh is argument for it.

Example: for python with virtualenv with main script app.py it will look like:

{
  "run": ["./venv/bin/python", "app.py"]
}
