loch functions invoke

Invoke a function with a JSON event and print its response

Synopsis

Invoke a function. The event is one JSON value (at most 6 MiB): --event <file> (- for stdin), --event-json, stdin when it is not a terminal (empty: {}), or {}. An event holding tokens belongs in a file or on stdin, not in --event-json (shell history, process list). The response (payload) is printed on stdout, the end of the invocation's logs and the status on stderr. Both were written by the function code: control characters are replaced unless --raw (payload bytes exactly as returned, e.g. to redirect them to a file). The exit code is 1 when the function returned an error (functionError) or the invocation failed.

loch functions invoke <name> [--event file.json | --event-json '<json>' | < event.json] [flags]

Examples

  loch functions invoke thumbnail --event-json '{"key": "photos/cat.jpg"}'
  loch functions invoke thumbnail --event s3-put.json
  echo '{}' | loch functions invoke thumbnail --raw > response.json

  -o, --output string       Output format: table or json (default "table")
