jenkins集成gitlab实现自动构建

jenkins集成gitlab实现自动构建

前面我们已经部署了Jenkins和gitlab，本文介绍将二者结合使用

项目源码上传至gitee提供公网访问：https://gitee.com/ye-xiao-tian/my-webapp

1、创建一个群组和项目

2、添加ssh密钥

#生成密钥
[root@gitlab ~]# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:HJjcMIYHlwUFFK6gg3stiFTEyQ6fODeYED8YfcggOUU root@gitlab
The key's randomart image is:
+---[RSA 2048]----+
|=OEoo+XBo        |
|===+o=o*         |
|o.@o..= o        |
|.*.O . . .       |
|+.o o   S        |
|o+ .             |
|+ o .            |
| . .             |
|                 |
+----[SHA256]-----+
[root@gitlab ~]# ll .ssh/
total 8
-rw-------. 1 root root 1675 May 22 09:33 id_rsa #私钥
-rw-r--r--. 1 root root  393 May 22 09:33 id_rsa.pub #公钥
[root@gitlab ~]# cat .ssh/id_rsa.pub

3、将公钥贴近gitlab

4、推送本地代码

#上传本地代码至gitlab
[root@gitlab my-webapp]# pwd
/root/data/my-webapp
[root@gitlab my-webapp]# ll
total 4
-rw-r--r--. 1 root root 1032 May 22 09:14 pom.xml
drwxr-xr-x. 3 root root   18 May 22 09:14 src#初始化代码
[root@gitlab my-webapp]# git init
Initialized empty Git repository in /root/data/my-webapp/.git/#配置邮件
[root@gitlab my-webapp]# git config --local user.name "Administrator"
[root@gitlab my-webapp]# git config --local user.email "[e-mail]"#上传
[root@gitlab my-webapp]# git add .
[root@gitlab my-webapp]# git commit -m "第一次上传"
[root@gitlab my-webapp]# git remote add origin http://192.168.232.135:1000/ops/my-webapp.git#账号为root
#密码前面重置的密码
[root@gitlab my-webapp]# git push origin master

• 页面查看上传的代码 （切换：master分支）
  

5、配置jenkins和gitlab的免密

5.1 jenkins容器生成密钥

[root@localhost ~]# docker exec -it -uroot jenkins bash
root@113b3ee555be:/# ssh-keygen
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa): 
Created directory '/root/.ssh'.
Enter passphrase (empty for no passphrase): 
Enter same passphrase again: 
Your identification has been saved in /root/.ssh/id_rsa
Your public key has been saved in /root/.ssh/id_rsa.pub
The key fingerprint is:
SHA256:Lk51oldcp/ZfdUyj2AuFHLpd3pM9K7X1OXGKrOZ0kkM root@113b3ee555be
The key's randomart image is:
+---[RSA 3072]----+
|           .     |
|          o o    |
|         . o.o...|
|         .o.*ooo+|
|        S.E+o+ BB|
|       + = +.oo.&|
|      + o = +oo=o|
|     o o ..=  ..o|
|      .  oo     .|
+----[SHA256]-----+
root@113b3ee555be:/# cat /root/.ssh/id_rsa.pub 
ssh-rsa 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 root@113b3ee555be

5. 2 将公钥加入gitlab

5.3 测试拉去代码

root@113b3ee555be:~# git clone git@192.168.232.135:ops/my-webapp.git
Cloning into 'my-webapp'...
remote: Enumerating objects: 16, done.
remote: Total 16 (delta 0), reused 0 (delta 0), pack-reused 16 (from 1)
Receiving objects: 100% (16/16), 4.32 KiB | 4.32 MiB/s, done.
root@113b3ee555be:~# ls
apache-maven-3.8.8  apache-maven-3.8.8-bin.tar.gz  my-webapp
#切换mater分支
root@113b3ee555be:~/my-webapp# git checkout master
branch 'master' set up to track 'origin/master'.
Switched to a new branch 'master'
root@113b3ee555be:~/my-webapp# ls
pom.xml  src

6、配置jenkins拉去gitlab代码

6.1 jenkins创建项目

6.2 点击立即构建

• 控制台输出查看日志 success表示成功

  

6.3 服务器查看代码已成功拉去至Jenkins工作目录

root@113b3ee555be:~# ls -ll /var/jenkins_home/workspace/my-wenapp/
total 4
-rw-r--r--. 1 jenkins jenkins 1032 May 24 23:17 pom.xml

root@d91c10166cdf:/# curl 127.0.0.1:8888
Hello! 你已成功第一次访问到8888端口服务！

7、配置webhook自动构建

7.1 jenkins页面配置

7.1.1 安装gitlab插件

7.1.2 记录webhook的url地址

http://192.168.232.136:8099/project/my-wenap

7.1.3 点击《高级》生产token

7.2 gitlab页面配置

7.2.1 输入url地址和token，触发来源：所有分支

7.2.2 点击测试 状态返回值为200，表示成功

8、修改代码重新提交后，发起自动构建

[root@gitlab ~]# vim data/my-webapp/src/main/java/com/example/controller/DemoController.java 
import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.RestController;@RestController
public class DemoController {@GetMapping("/")public String hello() {return "Hello! 你已成功第二次访问到8888端口服务！！";}
}[root@gitlab ~]# cd data/my-webapp/
#拉取远程代码更新合并
[root@gitlab my-webapp]# git pull origin master
From http://192.168.232.135:1000/ops/my-webapp* branch            master     -> FETCH_HEAD[root@gitlab my-webapp]# git add .
[root@gitlab my-webapp]# git commit -m "第二次提交"

remote: 
To http://192.168.232.135:1000/ops/my-webapp.git61dd8c2..efb4242  master -> master

• 刷新页面自动构建

#杀手前面的java进程
root@d91c10166cdf:~# kill -9 81#再次启动进程
root@d91c10166cdf:~# cd /var/jenkins_home/workspace/my-wenapp/target/
