gitlab-runner结合docker部署项目全过程_其他编程

前提

1.搭建好gitlab（直接拉下来安装就好）

2.搭建好gitlab-runner（直接拉下来安装就好）

3.安装docker

使用gitlab创建一个springboot的工程

项目中会有一个.gitlab-ci.yml的文件

我根据我的要求更改文件如下：

variables:
  project_name: "ruoyi_test" #项目名称，所有项目必须唯一  必填
  port: "8453" #运行在服务器的端口
  java_opts: "-xdebug -xrunjdwp:transport=dt_socket,server=y,suspend=n,address=5005" #jvm的参数，可不设置
  spring_opts: "" #spring的参数，可不设置
  jar_path: "/ruoyi-admin"#打包jar的路径 
  jar_name: "ruoyi-admin.jar" #编译出的jar文件名称 必填
  project_path: "/project/ruoyi_admin" #项目运行的目录 必填
stages:
- auto_deploy
- restart
build_and_start:
  stage: auto_deploy
  tags: 
  - local
  script:
  - echo "============上传代码============"
  - bash /home/gitlab-runner/script/prepare.sh "$project_name" "$jar_name" "$project_path"
  - echo "============上传代码完毕，开始打包============"
  - bash /home/gitlab-runner/script/package.sh "$project_name" "$jar_name" "$project_path" "$jar_path"
  - echo "============打包完毕，开始运行============"
  - bash /home/gitlab-runner/script/run.sh "$jar_name" "$project_path" "$port" "$java_opts" "$spring_opts"
  when: manual
just_restart:
 stage: restart
 tags: 
 - local
 script:
 - bash /home/gitlab-runner/script/run.sh "$jar_name" "$project_path" "$port" "$java_opts" "$spring_opts"
 # 手动执行
 when: manual

步骤

1.主要的逻辑都在脚本中，主要流程是，docker中使用maven镜像，先从自己本地copy一份setting文件到/home/gitlab-runner/script目录下（需要配置加速），方便maven打包更快。

2.prepare.sh脚本内容，用于准备maven编译项目

#!/bin/bash
if [ -z "$1" ]; then 
  echo "未传入项目名"
  exit 1
fi

if [ -z "$2" ]; then 
  echo "未传入jar包名"
  exit 1
fi

if [ -z "$3" ]; then 
  echo "未传入运行路径"
  exit 1
fi

docker_name="$1"_maven
echo 即将创建docker-"$docker_name"
existflag=$(docker ps -a | grep "$docker_name")
echo $existflag
if [ -z "$existflag" ]; then
  docker run -itd --name $docker_name maven:3.6.0-jdk-8-alpine /bin/bash
else
  docker stop $docker_name
  docker rm $docker_name
  docker run -itd --name $docker_name maven:3.6.0-jdk-8-alpine /bin/bash
fi
docker cp /home/gitlab-runner/script/settings.xml "$docker_name":/usr/share/maven/conf/settings.xml;
docker cp ./ "$docker_name":/home/"$1";

2.package.sh脚本内容，用户编译出jar包

#!/bin/bash

if [ -z "$1" ]; then 
  echo "未传入项目名"
  exit 1
fi

if [ -z "$2" ]; then 
  echo "未传入jar包名"
  exit 1
fi

if [ -z "$3" ]; then 
  echo "未传入运行路径"
  exit 1
fi
docker exec "$1"_maven bash -c "cd /home/$1; mvn clean; mvn package";
run_path=/ziyi"$3"
if [ ! -e $run_path ]; then
  mkdir -p $run_path
fi
docker cp "$1"_maven:/home/"$1""$4"/target/"$2" "$run_path"/"$2"
docker stop "$1"_maven
docker rm "$1"_maven

3.run.sh脚本内容，用于执行jar包。

#!/bin/bash

if [ -z "$1" ]; then 
  echo "未传入jar包名"
  exit 1
fi

if [ -z "$2" ]; then 
  echo "未传入运行路径"
  exit 1
fi
if [ -e "/ziyi$2/pidfile.txt" ]; then
  process=$(ps aux | grep `cat "/ziyi$2/pidfile.txt"`)
  if [ ! -z process ]; then
    echo "关闭之前的"`cat "/ziyi$2/pidfile.txt"`
    kill -9 `cat "/ziyi$2/pidfile.txt"`
  fi
fi
echo "启动-$2/$1-$4"
nohup java $4 -jar /ziyi$2/$1 --server.port=$3 $5 > /ziyi$2/logs.txt 2>&1 & echo $! > /ziyi$2/pidfile.txt

到这里点击项目的ci/di，项目就可以自动化运行了。（前提，需要在setting中设置一个ci/di，这个网上大部分教程都有）
