Invalid job file passes validation (w/ example)

[sheerun]

Hey,

I'm trying to run one-off task on nomad, but it keeps restarting over and over again.. Also the status is "failed" even return code from shell command is 0. How to schedule one-off shell job? My job description:

job "example" {
    datacenters = ["parallels"]

    group "shell" {
        task "ls" {
      type = "batch"

      driver = "raw_exec"

      config {
        command = "/bin/date"
      }

      resources {
        cpu = 250
        memory = 128
      }
    }
  }
}

Hmm. I think it's because type = "batch" belongs to job, not group.

Why nomad doesn't validate key names?

[dadgar]

Hey @sheerun. You are right the type belongs at the top. This is an invalid job file and it should have a validation error. I am going to keep this issue open till this job file fails validation.

As for running a job one-off. batch is the correct way.
