interpolation does not work for destination in artifact stanza

[Fuco1]

Copy of now closed #2752

Nomad version

Nomad v0.9.5

Operating system and Environment details

CentOS Linux release 7.3.1611 (Core)

Issue

interpolation does not work in artifact { destination = "destination" } stanza

Reproduction steps

create job with example from "Job file section"

nomad validate and nomad run executes with no errors.

nomad status -verbose example shows that download has been completed and task started
but as you can see from logs, task is terminated because, in my case, start script expected to be in /tmp/example-job/start.sh

Checking content of allocation on node that was assigned to run a task:

ls your_nomad_allocation_dir

...
...
drwxr-xr-x   3 root   root      17 Jun 28 13:08 ${NOMAD_META_DESTINATION_DIR}
...

Nomad Server logs

$ nomad validate example.nomad
Job validation successful

Thanks for re-creating this one, @Fuco1. I noticed you changed the version to 0.9.5 from the original issue; are you experiencing this problem with 0.9.5?

[Fuco1]

@tgross yes indeed, I'm using 0.9.5. My OS is also different (ubuntu 16.04 if I'm not mistaken) but that shouldn't play a big role. But if necessary I can check exact build when I get to the office.

Edit: the repro steps are the same.

I don't think this is supported at this point. Looking at https://github.com/hashicorp/nomad/blob/master/client/allocrunner/taskrunner/getter/getter.go#L100 the destination is taken as is and never interpolated. @tgross do you think this should be working already?
