带有 docker-machine 执行器的 Gitlab runner 不会接受任何工作

Question

使用以下配置创建了一个 gitlab runner：

concurrent = 1
check_interval = 0

[[runners]]
  name = "AWS EC2 gitlab runner for docker+machine"
  url = "xxx"
  id = 12
  token = "xxx"
  token_obtained_at = 2023-03-03T12:51:47Z
  token_expires_at = 0001-01-01T00:00:00Z
  executor = "docker+machine"
  limit = 1
  [runners.docker]
    image = "alpine"
    privileged = true
    disable_cache = true
  [runners.cache]
    Type = "s3"
    Shared = true
    [runners.cache.s3]
      ServerAddress = "s3.amazonaws.com"
      AccessKey = "xxx"
      SecretKey = "xxx"
      BucketName = "xxx"
      BucketLocation = "eu-central-1"
  [runners.machine]
    IdleCount = 2
    IdleTime = 1800
    MaxBuilds = 5
    MachineDriver = "amazonec2"
    MachineName = "gitlab-docker-machine-%s"
    MachineOptions = [
      "amazonec2-access-key=xxx",
      "amazonec2-secret-key=xxx",
      "amazonec2-region=us-east-1",
      "amazonec2-vpc-id=vpc-0002c60ca6e606633",
      "amazonec2-subnet-id=subnet-00aa337797dccfa6c",
      "amazonec2-use-private-address=true",
      "amazonec2-tags=runner-manager-name,gitlab-aws-autoscaler,gitlab,true,gitlab-runner-autoscale,true",
      "amazonec2-security-group=default",
      "amazonec2-instance-type=m4.large",
      "amazonec2-request-spot-instance=true",
      "amazonec2-spot-price=0.5",
      "amazonec2-zone=e",
    ]
    [[runners.machine.autoscaling]]
      Periods = ["* * 9-17 * * mon-fri *"]
      IdleCount = 50
      IdleTime = 3600
      Timezone = "UTC"
    [[runners.machine.autoscaling]]
      Periods = ["* * * * * sat,sun *"]
      IdleCount = 5
      IdleTime = 60
      Timezone = "UTC"

遵循官方 gitlab 文档 - https://docs.gitlab.com/runner/configuration/runner_autoscale_aws.

机器确实出现在 AWS 控制台中。然而，这份工作永远不会被接受： 此作业尚未开始 这项工作处于待定状态，正在等待跑步者挑选

我试过玩弄配置。重新创建了整个 gilab runner。而且，甚至改变了 AWS 区域。

唯一一次完成工作是在我运行时：

sudo gitlab-runner --debug run

但是，即便如此，它也会永远挂在：
