A keybase bot hosted on AWS Lambda

TL;DR:

• This is a project to get https://github.com/keybase/keybase-bot running on AWS lambda

• AWS Lambda doesnt ship with the which binary, or obscures access, so const keybaseBinaryLocation = await whichKeybase(); became const keybaseBinaryLocation = process.env['LAMBDA_TASK_ROOT'] + '/gopath/bin/keybase';

• keybaseStatus was not returning the device name. i didn't want to bug the keybase devs with questions about why this was, so

if (status && status.Username && status.Device && status.Device.name) {
    return {
      username: status.Username,
      devicename: status.Device.name,
      homeDir
    };
  }

became

if(status) {
    return {
      username: 'beemo',
      devicename: 'awslambda',
      homeDir
    };
   }

The compiled keybase go client binary is just in gopath/bin - maybe worth noting that it was built on ec2 amazon linux instance.

To build, run zip -r KeybaseBot.zip . then upload to lambda and config the username + paperkey envvars within lambda`
