## The GPG setup

#!/bin/bash

# This script expects AWS credentials:
#   SIGNIN_AWS_ACCESS_KEY_ID
#   SIGNIN_AWS_SECRET_ACCESS_KEY
# And optionally the TOTP entry name in your yubikey
#   SIGNIN_AWS_YUBIKEY_OATH_NAME
# Put these environment variables into your .bashrc.local (or .bashrc, if you
# don't sync dot-files). In your .bashrc you'll also want:
#   alias signin-aws='eval `signin-aws`'

Example Configuration for tc-worker with script-engine

Example task: https://tools.taskcluster.net/groups/FxNyHL2oRnWBFzWUdqIkGQ/tasks/FxNyHL2oRnWBFzWUdqIkGQ/details

This works with any clientId/accessToken that has the scope: assume:project:autophone:custom-worker-scopes Notice, that you can take the scopes from that role and make them more specific, so workers have fewer permissions.

title: Schema for Exposing Actions
description: |
  This document specifies the schema for the `public/actions.json` used by
  _decision tasks_ to expose actions that can be triggered by end-users.

  For the purpose of this document the _consumer_ is the user-interface that
  displays task results to the end-user and allows end-users to trigger actions
  defined by `public/actions.json`. A _consumer_ might be Treeherder.
