We are using Nomad as proof of concept on Windows clients mainly to run ASP.NET applications as services and running batch jobs.
Problem is big dependency package (~3-10GB) that we need on Windows client to run batch job. It there a way to download package once for Nomad batch job? And then use nomad job dispatch to run batch with specific arguments without downloading the artifact every time?
I would like to also provide parameters from file to Nomad batch job (this is what normally I would add to config–>args line). What is the best way to accomplish that?
What I’ve already tried:
- use lifecycle stanza to download artifact as prestart, but when I run nomad job dispatch It will download artifact again. I looked for some conditional statement to check if it already exist and then not downloading it again but I found nothing that could work.
hook = “prestart”
sidecar = false
One more question related to job working directory. I know that for now is it not possible to change it in the job specification ([Improvement] Configurable working directory for exec/raw_exec · Issue #2224 · hashicorp/nomad · GitHub). I used workaround with CMD do change working directory with :“cd /path/to/binary/dir/ && executable parameters…”. But using this I don’t have logs in Nomad. Do you have maybe solution for this?
Sorry for too much questions and thank you in advance for answer
