## Task Identifiers
Nomad will pass both the allocation ID and name as well as the task and job's
names. These are given as `NOMAD_ALLOC_ID`, `NOMAD_ALLOC_NAME`,
`NOMAD_ALLOC_INDEX`, `NOMAD_JOB_NAME`, and `NOMAD_TASK_NAME`. The allocation ID
and index can be useful when the task being run needs a unique identifier or to
know its instance count.
