Maven挂起码头容器内的下载

Question

我有一个gitlab与gitlab ci和一个跑步者，所有运行良好的一台CoreOs机器。

所有3个服务都使用以下dockerfiles服务文件和构建脚本运行：

构建脚本：

git submodule update --init

ls -la

mvn install

CI服务：

    [Unit]
    Description=CI

    # Requirements

    Requires=db.service
    Requires=gitlab.service
    Requires=redis.service

    After=gitlab.service
    After=redis.service

    [Service]
    User=core

    # Let the process take awhile to start up (for first run Docker containers)
    TimeoutStartSec=0

    # Get CoreOS environmental variables
    EnvironmentFile=/etc/environment

    # Pre-start and Start
    ## Directives with "=-" are allowed to fail without consequence
    KillMode=none
    Restart=always
    RestartSec=2

    ExecStartPre=-/usr/bin/docker kill ci
    ExecStartPre=-/usr/bin/docker rm ci

    # Stop
    ExecStop=/usr/bin/docker stop ci

接线员服务：

        ExecStartPre=-/usr/bin/docker kill ci-runner-maven-dart
        ExecStartPre=-/usr/bin/docker rm ci-runner-maven-dart
        ExecStartPre=/usr/bin/docker pull registry.globaleda.pt/globaleda/ci-runner-maven-dart:latest

            -v /data/ci-runner-maven-dart:/home/gitlab_ci_runner/data \
            registry.globaleda.pt/globaleda/ci-runner-maven-dart:latest

        # Stop
        ExecStop=/usr/bin/docker stop ci-runner-maven-dart

Ci runner博士文件：

MAINTAINER jrofurtado@gmail.com

RUN apt-get update
RUN apt-get install curl -y

# Install dartIn the dockerfile i added ENV MAVEN_OPTS -Djava.net.preferIPv4Stack=true

RUN apt-get install apt-transport-https -y
RUN sh -c 'curl https://dl-ssl.google.com/linux/linux_signing_key.pub | apt-key add -'

Ci dockerfile是sameersbn/gitlab:5.2.0的未经修改的版本。

当我编译一个maven项目(使用mvn安装)时，它开始下载所需的工件，并且下载挂起，如果我一次又一次地尝试下载，它会设法完全下载，问题是我需要一次不间断地下载(它设法继续使im将所有下载存储在映射的卷上)。

意见：

-I将Ci运行器容器部署在本地机器上，而不是服务器上，并链接到gitlab，问题依然存在。

-If您进入容器内部(使用docker -输入脚本或docker容器bash)并在终端上运行mvn，它可以下载所有应该下载的东西，尽管下载到挂起的构建中。

-i尝试在CI的dockerfile上将MAVEN_OPTS设置为-Djava.net.preferIPv4Stack=true，我还尝试将其包含在CI的构建脚本中以强制这个变量：

• 在dockerfile中，我添加了ENV MAVEN_OPTS -Djava.net.preferIPv4Stack=true
• 在构建脚本中，我添加了MAVEN_OPTS=-Djava.net.preferIPv4Stack=true

-Running处于调试模式(-e)或读取日志，我拥有的唯一信息是:下载超时

Answer 1

更新: Maven实际上没有挂起，构建已经完成，运行程序没有与gitlab通信，因为响应错误: 500，它成功地完成了它的工作。

确保您的VPN关闭;-)

我在谷歌上搜索了同样的问题。在阅读了下面的评论之后

似乎存在一些网络权限/防火墙问题。

我记得我使用的是VPN连接。关闭VPN解决了我的问题。
