概述

为了配置方便，我们使用 docker 来部署 GitLab Runner

环境准备

• 创建工作目录 /usr/local/docker/runner
• 创建构建目录 /usr/local/docker/runner/environment
• 下载 jdk-8u152-linux-x64.tar.gz 并复制到 /usr/local/docker/runner/environment

Dockerfile

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

FROM gitlab/gitlab-runner:v11.0.2

# 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 - && \

    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

# 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://192.168.75.146:8080/

# 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

# 这里选择 true ，可以用于代码上传后直接执行
Whether to run untagged builds [true/false]:
true

# 这里选择 false，可以直接回车，默认为 false
Whether to lock Runner to current project [true/false]:
false

# 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

附：项目配置 Dockerfile 案例

FROM openjdk:8-jre
