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 
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQDWTLxhCGI7yBFlfv8taFULt4yCLni4z3apIMqXUrKZXzieoM6SRk6VtNEOc0H+mGlEa42gAdrJjZy93/Po4fWI63NHQbzmvUXlbWxV6SePrrZuijafDpKJnZB1fyvmujAU2pYXX8ZdfpAPK5Y0OGGwkRAHWw9I2VGMjtNAHR2XIXTFZSL73rPww2gpqay6n5/JP2z+EmaViRVHKHt8G4oS2XYVK06iKhYCfEOF1UIf3uam77jc17A/v7MCyxExP8pNC9wsY5Z/t/zp9k5Sy5m4Is2nveiuk4uy+QVYFbISC3rVz2grYQ8sInBT3Py09fdJpA6/Ta/kIwe5P3pr9gI/ root@gitlab

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 "gitlab_admin_0cd627@example.com"#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
  1. 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.
