How to parameterize a Hashicorp's Nomad Job for user-defined variables?

How to parameterize a Hashicorp's Nomad Job for user-defined variables?

Description

This sample Nomad job attempts to clone a github repository from a github account, and then perform ls command to verify if it downloaded.

However, the cool thing is, it uses parameterized construct to parameterize the repository name so I can re-use this nomad job to clone any repository at runtime.

Motivation for writing

Erlang/OTP libraries/modules replaced by third party projects

I'm looking to collect information on why certain functionality found in Erlang/OTP is usually handled instead by a third party library in people's projects.

This could be bugs, missing functionality, poor interface, performance, etc.

Examples off the top of my head that need expanding on are:

  • httpc
  • httpd
  • http_uri

Adding a zfs dataset to a SmartOS zone. Seems there's no vmadm api for this, but you can do it with zonecfg:
# vmadm halt <uuid>
# zonecfg -z <uuid>
zonecfg:uuid> add dataset
zonecfg:uuid:dataset> set name=<zfs/path>
zonecfg:uuid:dataset> end
zonecfg:uuid> commit
zonecfg:uuid> exit
# zfs set mountpoint=legacy <zfs/path>
# vmadm boot <uuid>
