Use this node.js snippet to get Lambda execution of a bash command. In this case bash is just doing a curl to a URL. You could also write an entire bash script and call it.

var child_process = require('child_process');

exports.handler = function(event, context) {
  var child = child_process.spawn('/bin/bash', [ '-c', 'curl --silent --output - --max-time 1 https://fordodone.com/jobtrigger || true' ], { stdio: 'inherit' });

  child.on('close', function(code) {
    if(code !== 0) {
      return context.done(new Error("non zero process exit code"));
    }

    context.done(null);
  });
}
