我想从一个游牧者的工作中运行一个cassandra容器。它似乎开始了，但几秒钟后就死了（它似乎是被游牧民族自己杀死的）。
如果我从命令行运行容器，使用：

docker run --name some-cassandra -p 9042:9042 -d cassandra:3.0

容器启动完美无瑕。但如果我创造一个这样的游牧工作：

job "cassandra" {

  datacenters = ["dc1"]

  type = "service"

  update {
    max_parallel = 1
    min_healthy_time = "10s"
    healthy_deadline = "5m"
    progress_deadline = "10m"
    auto_revert = false
    canary = 0
  }

  migrate {
    max_parallel = 1
    health_check = "checks"
    min_healthy_time = "10s"
    healthy_deadline = "5m"
  }

  group "cassandra" {
    restart {
      attempts = 2
      interval = "240s"
      delay = "120s"
      mode = "delay"
    }

    task "cassandra" {
      driver = "docker"

      config {
        image = "cassandra:3.0"
        network_mode = "bridge"
        port_map {
          cql = 9042
        }
      }

      resources {
        memory = 2048
        cpu = 800
        network {
          port "cql" {}
        }
      }

      env {
        CASSANDRA_LISTEN_ADDRESS = "${NOMAD_IP_cql}"
      }

      service {
        name = "cassandra"
        tags = ["global", "cassandra"]
        port = "cql"
      }
    }
  }
}

那它就永远不会开始了。nomad的web界面在创建的分配的stdout日志中没有显示任何内容，stdin流只显示killed。
我知道当这发生时，docker容器被创建，并在几秒钟后被移除。我看不懂这些容器的日志，因为当我尝试（用 docker logs <container_id> )，我得到的是：

Error response from daemon: configured logging driver does not support reading

分配概览显示以下消息：

12/06/18 14:16:04   Terminated  Exit Code: 137, Exit Message: "Docker container exited with non-zero exit code: 137"

据docker说：
如果容器启动时没有初始化数据库，则将创建默认数据库。虽然这是预期的行为，但这意味着在初始化完成之前，它不会接受传入连接。在使用自动化工具（如docker compose）同时启动多个容器时，这可能会导致问题。
但我怀疑这是我问题的根源，因为我增加了 restart 节值无效，因为任务在几秒钟后就失败了。
不久前，我遇到了一个类似的问题 kafka 事实证明，容器并不快乐，因为它需要更多的记忆。但在本例中，我为内存和cpu提供了大量的值 resources 这似乎没有什么区别。
我的主机操作系统是ArchLinux，带有内核 4.19.4-arch1-1-ARCH . 我将consul作为systemd服务运行，nomad代理使用以下命令行：

sudo nomad agent -dev

我可能会错过什么？任何帮助和/或指点都将不胜感激。
更新（2018-12-06 16:26 gmt）：通过详细阅读nomad代理的输出，我得到一些有价值的信息可以在主机上读取 /tmp 目录。输出的一个片段：

更新（2018-12-06 16:40 gmt）：很明显，代理需要登录syslog，因此我设置并启动了一个本地syslog服务器，但没有效果。系统日志服务器没有收到任何消息。
