无法查询docker版本：获取https：// <ip> /v1.15/version：远程错误：tls：证书错误

Question

我正在使用gitlabRunner在数字海洋服务器上运行测试

重新安装gitlabRunner之后，我开始出现以下错误：

我的跑步者具有以下配置：

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 = 0
    IdleTime = 0
    OffPeakTimezone = ""
    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

在构建运行时，我尝试执行docker-machine ls，并且看到以下输出：

... ERRORS
... Unknown   Unable to query docker version: Cannot connect to the docker engine endpoint

或

... ERRORS
... Unable to query docker version: Get https://<ip>:2376/v1.15/version: remote error: tls: bad certificate

我尝试使用find -name "*cert*"在服务器上搜索证书，并在/root/.docker/machine/certs中找到了它们。我已按照docs中的说明在[runners.docker]部分中添加了证书路径，但没有帮助：

[runners.docker]
  ...
  tls_cert_path = "/root/.docker/machine/certs"

当我使用journalctl -u gitlab-runner查看gitlab运行程序日志时，

Jan 13 21:06:59 builds-coordinator gitlab-runner[3360]: ERROR: Error creating machine: Error checking the host: Error checking and/or regenerating the certs: There was an error validating certificates for host "<ip>:2376": remote error: tls: bad certificate  driver=digitalocean name=r

在我使用gitlabRunner版本11.5.1

之前

如何解决这些错误并使gitlab运行程序运行构建？
