Question

我在docker的机器上运行 - 组成以下内容：

gitlab
无人机（服务器）
无人机（代理人）

当我触发构建（或由git push触发）时，无人机在问题上继续失败：

git init
Initialized empty Git repository in /drone/src/.git/
git remote add origin http://my-git/amaziagur/location-service.git
git fetch --no-tags origin +refs/heads/master:
fatal: unable to access 'http://my-git/amaziagur/location-service.git/': Couldn't resolve host 'my-git'
exit status 128

这是docker-compose.yml：

两者都安装在同一台机器上，我无法弄清楚我做错了什么，无人机无法识别git主机的原因是什么。

我已经在我的本地/ etc / hosts和/etc/resolve.conf中添加了我在网络上找到的提示。有人可以帮忙吗？

Answer 1

Brad Rydzewski's comment让我走上正轨。他说：

配置gitlab时，您需要使用IP地址或域名。您无法使用内部docker主机名（例如my-git），因为当无人机生成管道容器时，这些容器将位于不同的网络上，并且无法解析my-git

这是完全正确的。以下是对我有用的最终配置：

version: '2'
services:
    web:
      image: 'gitlab/gitlab-ce:latest'
      restart: always
      environment:
        GITLAB_OMNIBUS_CONFIG: |
          external_url '<IP address or domain name>'
          gitlab_rails['gitlab_shell_ssh_port'] = 22
          # Add any other gitlab.rb configuration here, each on its own line
      ports:
        - '80:80'
        - '443:443'
        - '22:22'
      volumes:
        - '/srv/gitlab/config:/etc/gitlab'
        - '/srv/gitlab/logs:/var/log/gitlab'
        - '/srv/gitlab/data:/var/opt/gitlab'

    drone-server:
      image: drone/drone:0.7.3
      links:
        - web
      ports:
        - "8000:8000"
      volumes:
        - /home/drone:/var/lib/drone/
      environment:
        DRONE_OPEN: "true"
        DRONE_HOST: "<IP address or domain name> : <port>"
        DRONE_ADMIN: <admin users - should be git user names>
        DRONE_GITLAB: "true"
        DRONE_GITLAB_URL: "<IP address or domain name>"
        DRONE_GITLAB_CLIENT: "<Application Id in gitlab>"
        DRONE_GITLAB_SECRET: "<Secret in gitlab>"
        DRONE_SECRET: "<secret drone>"
    drone-agent:
      image: drone/drone:0.7.3
      command: agent
      depends_on:
        - drone-server
      volumes:
        - /var/run/docker.sock:/var/run/docker.sock
      environment:
        DRONE_SERVER: ws://drone-server:8000/ws/broker
        DRONE_DEBUG: "true"
        DRONE_SECRET: "<secret drone>"

Answer 2

TL; DR

主要原因是因为实际的克隆步骤是由特定的独立docker容器驱动的，该容器位于其自己的docker网络中。因此它无法解析名称my-git，即使它能够解析它，也无法找到它。

预期的解决方法失败：

首先，您会注意到您的错误与解决 my-git有关。 必须在实际进行克隆的docker git容器实例上解决，而不是在其他任何地方。这意味着修改此docker实例的/etc/hosts。这可以在您的.drone.yml中完成，方法是替换您的克隆步骤，并使用docker-compose的{{1}}功能（参见docs）。就是这样的：

extra_hosts

A，如果您的容器现在能够kind: pipeline name: default clone: disable: true steps: - name: myclone image: docker:git ## If you wanted to solve resolving part extra_hosts: - "my-git:10.0.0.200" ## Alas this will also be needed, and is NOT supported yet # networks: # - gitlab commands: ## this will show you if ``my-git`` is resolved. - ping -c 1 my-git - git clone http://my-git/amaziagur/location-service.git/ ## ## ... your normal steps follows ... ##解析为实际IP，则它仍将无法访问，因为它是在未连接到另一个的自定义网络中生成的。

为此，我们还需要能够指定docker实例应该连接到的网络，通常通过my-git中的networks键（如您所可以签入docker-compose reference about specifying custom networks）。

A，目前docker-compose不支持此功能，并且是this issue当前跟踪的错误。截至撰写本文时，即使在drone中也没有解决该问题。

请注意，如果1.0.0-rc.5键可以按预期工作，则networks将是多余的。

Answer 3

由于这是该问题排名最高的问题，我想对此进行总结。

previously mentioned issue拥有您需要的响应，但尚不明确，因为它在github mentions日志中，并且最初链接的问题已关闭而没有解决方案。

解决方案

您可以将DRONE_RUNNER_NETWORKS =传递给代理（或服务器（如果您不使用代理）。当无人机产生容器时它将所有容器附加到指定的网络。

来源： https://discourse.drone.io/t/gitea-drone-traefik-agent-cannot-reach-git-repo/4170/2?u=bradrydzewski

请注意，您还希望在docker-compose https://docs.docker.com/compose/networking/#specify-custom-networks中将网络添加到运行程序中-否则初始ping操作将失败，并且不会产生更多运行程序。

一个完整的无人码头工人的例子：

drone-runner-docker:
  volumes:
      - '/var/run/docker.sock:/var/run/docker.sock'
  environment:
      - DRONE_RPC_PROTO=http
      - DRONE_RPC_HOST=172.20.0.19
      - DRONE_RPC_SECRET=SECRET
      - DRONE_RUNNER_CAPACITY=2
      - DRONE_RUNNER_NAME=drone-runner-docker
      - DRONE_RUNNER_NETWORKS=droneio_network,another_network
  networks:
      droneio_network:
      another_network:
  ports:
      - '3000'
  restart: always
  image: 'drone/drone-runner-docker:latest'

有关变量的解释，请参见drone docs。

确保您在环境中为DRONE_RUNNER_NETWORKS提供的名称是来自docker network ls的实际网络名称。（如果是通过docker-compose生成的，它们通常具有infront的文件夹名称，例如foldername_default）
