Nomad

Hello, i have parameterized jobs of aws cli below
The question is, how to pass the meta as multiple arguments?

I want to dispatch job like this:

nomad job dispatch -meta aws_cmd="s3 ls s3://mybucket" aws-cli

job "aws-cli" {
  type = "batch"

  parameterized {
    meta_required = ["aws_cmd"]
  }

  group "aws-cli" {
    network {
      mode = "bridge"
    }

    restart {
      attempts = 0
      mode     = "fail"
    }

    reschedule {
      attempts  = 0
      unlimited = false
    }

    task "aws-cli" {
      driver = "docker"
      shutdown_delay = "10s"

      config {
        image   = "amazon/aws-cli:2.22.4"
        command = "{{ env NOMAD_META_aws_cmd | split \"\n\" | first }}"
        args    = [  "{{ env NOMAD_META_aws_cmd | split \"\n\" | pop }}" ]
        volumes = [
          "local/.aws_config:/root/.aws/config",
          "secrets/.aws_creds:/root/.aws/credentials",
        ]
      }

      template {
        data = <<EOH
[default]
region = ap-southeast-1
output = json
EOH

        destination = "local/.aws_config"
      }

      template {
        data = <<EOH
{{ with nomadVar "nomad/jobs/aws-cli" }}
[default]
aws_access_key_id = {{ .aws_access_key_id }}
aws_secret_access_key = {{ .aws_secret_access_key }}
{{ end }}
EOH

        destination = "secrets/.aws_creds"
      }

      resources {
        cpu        = 256
        memory     = 256
        memory_max = 512
      }
    }
  }
}

Hi. So shell splitting? sh -c "echo "hello world"'

entrypoint = ["sh", "-xc", NOMAD_META_aws_cmd]

Ah, nice @Kamilcuk!
I forgot the entrypoint stanza.

Thanks
