Nomad Community Autoscaler Plugin OS-NOVA Openstack

Dear Nomad Community,

I have a problem getting the Autoscaler Plugin for Openstack (OS-Nova) running. I think I am missing something.

I downloaded the OS-Nova Plugin from Github (GitHub - jorgemarey/nomad-nova-autoscaler) and put the files into the /plugins/os-nova folder inside the autoscaler container. So far so good but I am getting the following error:

The folder structure in the container looks like this:

and this is my config.hcl

http {
  bind_address = "0.0.0.0"
  bind_port = "8080"
}

policy {
  dir = "local/policies"
}

nomad {
  address = "https://10.0.0.173:4646"
  token = ""
  client_cert = "/opt/nomad/agent_certs/agent.crt"
  client_key = "/opt/nomad/agent_certs/agent.key"
  ca_cert = "/opt/nomad/agent_certs/ca.crt"
}

apm "prometheus" {
  driver = "prometheus"
  config = {
    address = "http://localhost:8081"
  }
}

target "os-nova" {
  driver = "os-nova"
  config = {
    auth_url    = ""
    username    = ""
    password    = ""
    domain_name = "default"
    project_id  = ""
  }
}

strategy "pass-through" {
  driver = "pass-through"
}

Any help would be much appreciated, I am stuck here for a while.

Thank you

Best
