python - 游牧者 : Unable to Run a python script

Question

我正在尝试将以下作业提交到我的游牧服务器。该作业基本上使用一个有效负载，它是来 self 的本地主机的 python 文件。

job "agent-collector-bot" {
  datacenters = ["staging"]

  type = "batch"

  periodic {
    cron             = "*/10 * * * *"
    prohibit_overlap = true
  }

  group "python-bot" {
    count = 1
    task "slack-bot" {
      driver = "raw_exec"

      config {
        command = "python"
        args = ["local/agent-collector-slackbot.py"]
      }

      dispatch_payload {
       file = "agent-collector-slackbot.py"
     }

    }
  }
}

现在，当我看到 nomad 中的工作状态时，它会显示:

snomad 状态代理-收集器-bot/

我检查了我的 nomad 客户端(所有 5 个)都安装了 python。有人可以帮助我吗？

Answer 1

输出中指定的驱动程序是 raw_exec，而不是 python。

您需要在客户端配置中启用它 ( nomad raw_exec docs )

client {
  options = {
    "driver.raw_exec.enable" = "1"
  }
}
