scopes:
  # Note the below scopes are insecure however these get overriden on the server
  # side to whatever scopes are set by mozilla-taskcluster.
  - queue:*
  - docker-worker:*
  - scheduler:*

# Available mustache parameters (see the mozilla-taskcluster source):
#
# - owner:          push user (email address)
# - source:         URL of this YAML file
# - url:            repository URL
# - project:        alias for the destination repository (basename of
#                   the repo url)
# - level:          SCM level of the destination repository
#                   (1 = try, 3 = core)
# - revision:       (short) hg revision of the head of the push
# - revision_hash:  (long) hg revision of the head of the push
# - comment:        comment of the push
# - pushlog_id:     id in the pushlog table of the repository
#
# and functions:
# - as_slugid:      convert a label into a slugId
# - from_now:       generate a timestamp at a fixed offset from now

# The resulting tasks' taskGroupId will be equal to the taskId of the first
# task listed here, which should be the decision task.  This gives other tools
# an easy way to determine the ID of the decision task that created a
# particular group.
