Hello, I always get the following error when trying to start the autoscaler container:

This is the local/config.hcl I use:

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

policy {
  dir = "local/policies"
}

nomad {
  address = "https://10.0.0.173:4646"
  token = "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    = "URL"
    username    = "USER"
    password    = "PASS"
    domain_name = "default"
    project_id  = "ID"
  }
}

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

Is there something I am missing? Been stuck here for a while. Thanks a lot. Best

Hi @RafaelReder did you managed to fix this?

[RafaelReder]

Yes thank you very much for answering. I missed to do the go build step before using the executable in the autoscaler.
