## 使用 GitLab Runner Docker ##

#### Dockerfile ####

--------------------

在 `/usr/local/docker/runner/environment` 目录下创建 `Dockerfile`

FROM gitlab/gitlab-runner:v11.1.0
    
    # 修改软件源
    RUN echo 'deb http://mirrors.aliyun.com/ubuntu/ xenial main restricted universe multiverse' > /etc/apt/sources.list && \
        echo 'deb http://mirrors.aliyun.com/ubuntu/ xenial-security main restricted universe multiverse' >> /etc/apt/sources.list && \
        echo 'deb http://mirrors.aliyun.com/ubuntu/ xenial-updates main restricted universe multiverse' >> /etc/apt/sources.list && \
        echo 'deb http://mirrors.aliyun.com/ubuntu/ xenial-backports main restricted universe multiverse' >> /etc/apt/sources.list && \
        apt-get update -y && \
        apt-get clean
    
    # 安装 Docker
    RUN apt-get -y install apt-transport-https ca-certificates curl software-properties-common && \
        curl -fsSL http://mirrors.aliyun.com/docker-ce/linux/ubuntu/gpg | apt-key add - && \
        add-apt-repository "deb [arch=amd64] http://mirrors.aliyun.com/docker-ce/linux/ubuntu $(lsb_release -cs) stable" && \
        apt-get update -y && \
        apt-get install -y docker-ce
    COPY daemon.json /etc/docker/daemon.json
    
    # 安装 Docker Compose
    WORKDIR /usr/local/bin
    RUN wget https://raw.githubusercontent.com/topsale/resources/master/docker/docker-compose
    RUN chmod +x docker-compose
    
    # 安装 Java
    RUN mkdir -p /usr/local/java
    WORKDIR /usr/local/java
    COPY jdk-8u152-linux-x64.tar.gz /usr/local/java
    RUN tar -zxvf jdk-8u152-linux-x64.tar.gz && \
        rm -fr jdk-8u152-linux-x64.tar.gz
    
    # 安装 Maven
    RUN mkdir -p /usr/local/maven
    WORKDIR /usr/local/maven
    RUN wget https://raw.githubusercontent.com/topsale/resources/master/maven/apache-maven-3.5.3-bin.tar.gz
    # COPY apache-maven-3.5.3-bin.tar.gz /usr/local/maven
    RUN tar -zxvf apache-maven-3.5.3-bin.tar.gz && \
        rm -fr apache-maven-3.5.3-bin.tar.gz
    # COPY settings.xml /usr/local/maven/apache-maven-3.5.3/conf/settings.xml
    
    # 配置环境变量
    ENV JAVA_HOME /usr/local/java/jdk1.8.0_152
    ENV MAVEN_HOME /usr/local/maven/apache-maven-3.5.3
    ENV PATH $PATH:$JAVA_HOME/bin:$MAVEN_HOME/bin
    
    WORKDIR /

#### daemon.json ####

--------------------

在 `/usr/local/docker/runner/environment` 目录下创建 `daemon.json`，用于配置加速器和仓库地址

{
      "registry-mirrors": [
        "https://registry.docker-cn.com"
      ],
      "insecure-registries": [
        "192.168.75.131:5000"
      ]
    }

#### docker-compose.yml ####

--------------------

在 `/usr/local/docker/runner` 目录下创建 `docker-compose.yml`

version: '3.1'
    services:
      gitlab-runner:
        build: environment
        restart: always
        container_name: gitlab-runner
        privileged: true
        volumes:
          - /usr/local/docker/runner/config:/etc/gitlab-runner
          - /var/run/docker.sock:/var/run/docker.sock

#### 注册 Runner ####

docker exec -it gitlab-runner gitlab-runner register
    
    # 输入 GitLab 地址
    Please enter the gitlab-ci coordinator URL (e.g. https://gitlab.com/):
    http://192.168.106.134:8080/
    
    # 输入 GitLab Token
    Please enter the gitlab-ci token for this runner:
    1Lxq_f1NRfCfeNbE5WRh
    
    # 输入 Runner 的说明
    Please enter the gitlab-ci description for this runner:
    可以为空
    
    # 设置 Tag，可以用于指定在构建规定的 tag 时触发 ci
    Please enter the gitlab-ci tags for this runner (comma separated):
    deploy
    
    # 选择 runner 执行器，这里我们选择的是 shell
    Please enter the executor: virtualbox, docker+machine, parallels, shell, ssh, docker-ssh+machine, kubernetes, docker, docker-ssh:
    shell

### 项目配置 Dockerfile ###

FROM openjdk:8-jre
    
    ENV APP_VERSION 1.0.0-SNAPSHOT
    ENV DOCKERIZE_VERSION v0.6.1
    RUN wget https://github.com/jwilder/dockerize/releases/download/$DOCKERIZE_VERSION/dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz \
        && tar -C /usr/local/bin -xzvf dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz \
        && rm dockerize-linux-amd64-$DOCKERIZE_VERSION.tar.gz
    
    RUN mkdir /app
    
    COPY itoken-eureka-$APP_VERSION.jar /app/app.jar
    ENTRYPOINT ["dockerize", "-timeout", "5m", "-wait", "tcp://192.168.75.128:8888", "java", "-Djava.security.egd=file:/dev/./urandom", "-jar", "/app/app.jar", "--spring.profiles.active=prod"]
    
    EXPOSE 8761

### 项目配置 docker-compose.yml ###

version: '3.1'
    services:
      itoken-eureka:

        container_name: itoken-eureka
        ports:
