 .gitlab-ci.yml

要实现CI/CD,首先要在项目根路径下创建.gitlab-ci.yml文件,我的目录结构如下:

Gitlab - Ubuntu18注册gitlab-runner并激活CI/CD_bash_07

.gitlab-ci.yml文件内容:



Gitlab - Ubuntu18注册gitlab-runner并激活CI/CD_linux

# CI/CD管道分三步,这里可以根据需求自行配置
stages:
- build
- test
- deploy
build:
stage: build
# 测试构建
script:
- gradle clean build -x test
test:
stage: test
# 这里可以写一些测试相关的脚本
script:
- echo SKIPPING TEST
deploy:
stage: deploy
script:
# 修改部署脚本文件类型为可执行文件
- chmod +x .gitlab-ci/deploy.sh
# 执行脚本
- sh .gitlab-ci/deploy.sh
only:
# 只有master分支执行这个步骤
- /^master.*$/
tags:
# 对应注册runner时候的tag名
- tag

deploy.sh文件内容:



Gitlab - Ubuntu18注册gitlab-runner并激活CI/CD_linux

#!/usr/bin/env bash

echo "Start deploying!"

gradle build

# 把文件从本地传到服务器上去
scp /home/gitlab-runner/builds/n637Af4S/0/root/project-test/build/libs/project-test-0.0.1-SNAPSHOT.jar root@服务器ip:/usr/local/project_test/project-test-0.0.1-SNAPSHOT.jar

# 执行服务器上的部署脚本文件
ssh root@服务器ip "sh /usr/local/project_test/deploy.sh"

echo "Deploy jar success!"

执行deploy.sh文件需要两个前提条件,一是需要gitlat服务器可以免密登录待部署服务器,而是要在待部署服务器上也创建一个deploy.sh文件。成功执行待部署服务器上的deploy.sh文件需要文件夹创建格式和我这里相同。

待部署服务器上的deploy.sh文件:



Gitlab - Ubuntu18注册gitlab-runner并激活CI/CD_linux

#!/bin/bash
#defined
export JAVA_HOME=/usr/local/java/jdk1.8.0_231


PID=`ps -ef | grep java | grep project-test | awk '{print $2}'`

if [ -z $PID_EXIST];then
echo the process $PID is not exist
else
echo the process $PID exist
kill -9 $PID
fi

echo "remover jar file"

rm -rf /jar/project-test*

echo "copy jar to dir"

cp project-test-0.0.1-SNAPSHOT.jar /usr/local/project_test/jar/project-test.jar

echo "start jar"

nohup java -jar /usr/local/project_test/jar/project-test.jar >/dev/null 2>&1 &

echo "started"

Q:提交代码后没有触发,一直停留在pending

A:报错:This job is stuck, because you don't have any active runners that can run this job.

原因:注册gitlab runner 的时候,有一步提示:Can run untagged jobs: [false/true],默认值为false。

这句话的意思是:是否在没有标记tag的job上运行,如果选择默认值false,那没有标记tag的代码提交是不会触发gitlab runner的,如果做测试,最好填true。
