Accessing environment variables from client.conf

Nomad
1

Hi, is it possible to access host environment variables from a nomad client.conf file?

I’ve tried this in the client block:


  host_volume "some-host-storage" {
    path =  "${SOME_PLACE}"
    read_only = false
  }

But then nomad starts without interpolating this variable:
client setup failed: node setup failed: failed to validate volume some-host-storage, err: stat ${SOME_PLACE}: no such file or directory"

Thanks!

Hi @jeteve,

Unfortunately the Nomad client configuration does not support environment variable interpolation. It is expected some form of configuration management would perform this work while writing the files to disk.

Thanks @jrasell , I was actually wondering about how to integrate nomad with configuration management. Are there some best practices around I could have a look at?

Thanks!

Hi @jeteve,

No best practices per-se, but here are some links to examples which utilise different approaches:
