gitlab runner的安装和基本使用:https://bear-coding.blog.csdn.net/article/details/120591711

安装并给项目配置完gitlab runner后再操作后面步骤。

实现目标：

1. master分支代码有变更的时候自动构建build。

2. 当开发人员在gitlab上给项目打一个tag标签分支的时候自动触发流水线，根据标签名称和分支名称来自动发布；

例如分支名称为"test_3.1.1.1_project1&project2"则发布到测试环境

例如分支名称为"prod_3.1.1.1_project1&project2"则发布到生产环境

在项目根目录下创建以下文件：

创建好之后，提交到gitlab上，就直接可以使用了

.gitlab-ci.yml 流水线文件

stages:
    - build
    - test
    - prod

#当master分支变更的时候触发
build:
    stage: build
    script: sh ./build.sh
    only:
        - master  #master主干有变更的发起编译任务
    tags:
        - trade_runner  #任务标签，根据此标签匹配gitlab runner的标签。

test:
    stage: test
    script: sh ./test.sh
    only:
        refs:
            - tags #创建tag分支且格式为”test_44.55.66.77_project1.project2“的时候发起发布任务
        variables:
            - $CI_COMMIT_TAG =~ /^test_[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+_[a-zA-Z0-9&\.]+$/
    tags:
        - trade_runner

prod:
    stage: prod
    script: sh ./prod.sh
    only:
        refs:
            - tags #创建tag分支且格式为”prod_44.55.66.77_project1.project2“的时候发起发布任务
        variables:
            - $CI_COMMIT_TAG =~ /^prod_[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+_[a-zA-Z0-9&\.]+$/
    tags:
        - trade_runner
    when: manual #设置需要手动触发

build.sh 执行编译项目的脚本文件

#!/bin/sh


echo "start build task,job_name=$CI_JOB_NAME"

#判断流水线任务必须是build
if [ "$CI_JOB_NAME" != "build" ]; then
    echo "error job name: $CI_JOB_NAME"
    exit 1
fi

cd GitLabTest/
dotnet build $build_args
#获取构建结果
build_result=$?
echo "end build task,$build_result"
exit $build_result

test.sh 执行发布测试环境的脚本

#!/bin/sh

thetime=`date +%Y%m%d%H%M`
tag_msg=`echo "$CI_COMMIT_TAG" | awk -F '_' '{print $3}' `
echo "start test task,tag=$CI_COMMIT_TAG,job_name=$CI_JOB_NAME,tag_message=$tag_msg,time=$thetime"

#判断流水线任务必须是deploy
if [ "$CI_JOB_NAME" != "test" ]; then
    echo "error job name: $CI_JOB_NAME"
    exit 1
fi

#要发布的项目列表
programs=(${tag_msg//&/ })

for program in ${programs[@]}
do
    #切换到要发布的项目里,并发布项目
    cd GitLabTest/$program
    echo "start publish $program"
    dotnet publish -c Release -r linux-x64 -p:PublishSingleFile=true $build_args -p:DebugSymbols=true -p:DebugType="portable"
    if [ $? != 0 ]; then
        echo "publish $program failed"
        exit 1
    fi
    echo "publish $program success"
    cd ../../
done

base_pwd=`pwd`
build_path_middle="publish"

for program in ${programs[@]}
do
    #将发布好的文件复制到发布目录下
    #也可以将文件打包成tar，传输到远程服务器上，或者生成docker镜像，推送到镜像服务器。见后面注释部分
    echo "start copy $program"
    #预先创建存放发布文件的目录，并将权限给到gitlab-runner
    #mkdir /usr/local/publish
    #chown -R gitlab-runner:gitlab-runner /usr/local/publish
    mkdir -p /usr/local/$build_path_middle/$program/
    cp -rf $base_pwd/GitLabTest/$program/bin/Release/net7.0/linux-x64/* /usr/local/$build_path_middle/$program/
    echo "copy $program success"
done

#将文件打包成tar，传输到远程服务器上，
#        rm -f program.tar.gz
#        tar zcf program.tar.gz -C publish --exclude "*.tar.gz" .
#        ssh -p $server_port $server_ip "mkdir -p $deploy_base_pwd/$program/"
#        ssh -p $server_port $server_ip "{ cd $deploy_base_pwd/$program/ && [ -s program.tar.gz ] && mv -f program.tar.gz program_bak.tar.gz; } || true"
#        scp -P $server_port program.tar.gz $server_ip:$deploy_base_pwd/$program/

#将文件生成docker镜像，并推送到镜像仓库
#docker build -f /usr/local/$build_path_middle/$program/Dockerfile -t 镜像仓库地址/trade-$program:${thetime} .
#docker push 镜像仓库地址/trade-$program:${thetime} 
#docker rmi 镜像仓库地址/trade-$program:${thetime} 

prod.sh 执行发布到生产环境的脚本，与test.sh基本一至，根据实际需要更改

#!/bin/sh

thetime=`date +%Y%m%d%H%M`
tag_msg=`echo "$CI_COMMIT_TAG" | awk -F '_' '{print $3}' `
echo "start product task,tag=$CI_COMMIT_TAG,job_name=$CI_JOB_NAME,tag_message=$tag_msg,time=$thetime"

#判断流水线任务必须是deploy
if [ "$CI_JOB_NAME" != "prod" ]; then
    echo "error job name: $CI_JOB_NAME"
    exit 1
fi

#要发布的项目列表
programs=(${tag_msg//&/ })

for program in ${programs[@]}
do
    #切换到要发布的项目里,并发布项目
    cd GitLabTest/$program
    echo "start publish $program"
    dotnet publish -c Release -r linux-x64 -p:PublishSingleFile=true $build_args -p:DebugSymbols=true -p:DebugType="portable"
    if [ $? != 0 ]; then
        echo "publish $program failed"
        exit 1
    fi
    echo "publish $program success"
    cd ../../
