Question

我希望始终有1个空闲运行器，它将缓存docker图像，以便当其他运行器选择作业时，这些图像会从闲置的运行程序镜像到新的运行程序，而不会从https://hub.docker.com

下载

我有以下gitlab运行程序配置

concurrent = 10
check_interval = 0

[session_server]
  session_timeout = 1800

[[runners]]
  name = "Builds coordinator"
  url = "https://gitlab.com/"
  token = "<token>"
  executor = "docker+machine"
  limit = 10
  [runners.docker]
    tls_verify = false
    image = "alpine:latest"
    privileged = false
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/cache"]
    shm_size = 0
  [runners.machine]
    IdleCount = 1
    IdleTime = 0
    OffPeakPeriods = [
      "* * 0-10,18-23 * * mon-fri *",
      "* * * * * sat,sun *"
    ]
    OffPeakTimezone = "Europe/Minsk"
    OffPeakIdleCount = 0
    OffPeakIdleTime = 0
    MachineDriver = "digitalocean"
    MachineName = "gitlab-runner-autoscale-%s"
    MachineOptions = [
        "digitalocean-image=coreos-stable",
        "digitalocean-ssh-user=core",
        "digitalocean-access-token=<token>",
        "digitalocean-region=lon1",
        "digitalocean-size=4gb",
        "digitalocean-private-networking"
    ]
  [runners.cache]
    Type = "s3"
    Path = "cache_for_builds"
    Shared = false
    [runners.cache.s3]
      ServerAddress = "ams3.digitaloceanspaces.com"
      AccessKey = "<key>"
      SecretKey = "<secret>"
      BucketName = "cache-for-builds"
      BucketLocation = "ams3"
      Insecure = false

当我启动一个包含10个工作的新管道时，将一个接一个地创建新的运行程序。首先，第一个作业由闲置的转轮来接，然后在10秒钟后创建一个新的空闲转轮，然后接第二个作业，依此类推。很慢

我希望当出现10个新工作时，协调员应检查是否有1个空闲转轮。它应该创建10个新运行程序来处理工作，并创建1个空闲运行程序。在我的情况下，它不应创建空闲的运行程序，因为每个令牌的运行程序限制为10

gitlab-runner --version给了我

Version:      11.5.1
Git revision: 7f00c780
Git branch:   11-5-stable
GO version:   go1.8.7
Built:        2018-12-06T13:25:34+0000
OS/Arch:      linux/amd64

目前，我通过拥有10个空闲运行程序解决了此问题，但我不想拥有10个空闲运行程序来加快docker映像下载过程。我如何才能只有1个闲置的运行程序，如何让其余的运行程序生成并快速选择新工作（我希望新的运行程序从空闲的运行程序下载docker映像）？

如果IdleCount不为零，则Gitlab运行程序选择新作业的速度太慢
