HCL Templates

Details about this specification can be found at: https://github.com/hashicorp/hcl

Variables

We have added support for variables in the template. We only support replacement of environment variables. You can use $ followed by a variable name $variable_name that would be replaced the environment variable value of variable_name. We do not support the convention of ${var} which is widely used in the industry because that convention is used by nomad (see: https://www.nomadproject.io/docs/runtime/interpolation.html#interpreted_node_vars)
