Jenkins免密拉取GitLab项目

1.在Jenkins上为GitLab创建一个专有的拉取代码的账号 Jenkins需要构建哪些项目就在GitLab给予账号相应权限 我这里已经创建过Jenkins用户,下面用它登录后添加SSH-KEY

干货分享建议收藏:Jenkins集成GitLab

2.在Jenkins服务器上生成ssh-key


[root@jenkins ~]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
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:IUQIuu0SAdSbZvENbIjFYTrUrnuqKGBmZtwPj6lvz60 root@jenkins
The key's randomart image is:
+---[RSA 2048]----+
|ooB=+oo          |
|ooo*.=           |
|oo. * + .        |
| +.* . o .       |
|+ *     S        |
|.@ o             |
|O o *            |
|oo =.o.          |
|=o*..E..         |
+----[SHA256]-----+

查看公钥

[root@jenkins ~]# cat /root/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7ckQQf4N93Rjf0ts3Lk4siL6FZmZiBiB+ouwTgw9kKof2NeJTguf0aNfDsgSEet4+bJ53ZKztsFZE/C+sqk7grqeLeYDFBWgdZBz1dmCYT51tRFmZPDEDclOIMc2tz0G50g6DFA1dvIfkzeVbKjBNN0o80FSAwAzrtjMrkyaDcrOmYekiSPM8JYJTTcFLCzIBXz7SXOmKH5vyoAIVpdcwnIhkHNLKfD0MdzGb7Kz/pKMnLubodcxyNir6fqw76qwMe1DE0NtQzpaCrTYhVnAizVqCDek0GMZjTG1vWYNn6a8G7omV3Gde1XjcmjAj6ftVQiVLBRJaIGKI4R/B//nd root@jenkins

将Jenkins的公钥填入GitLab账号中

3.测试SSH-KEY 到jenkins服务器上拉取项目来测试ssh-key免密是否生效

[root@jenkins ~]# yum install git -y
[root@jenkins ~]# git clone git@106.14.10.124:dev01/sample.git
正克隆到 'sample'...
The authenticity of host '106.14.10.124 (106.14.10.124)' can't be established.

如上,ssh-key已生效

配置jenkins自动拉取代码

1.jenkins 服务器添加证书 系统配置——》Manage Credentials

干货分享建议收藏:Jenkins集成GitLab

系统配置——》Manage Credentials——》Jenkins——》全局凭证——》添加凭证

干货分享建议收藏:Jenkins集成GitLab

这样的话Jenkins服务器拉取GitLab的代码就不需要再进行认证了。

Jenkins安装GitLab插件

1.安装插件 插件名称:

•GitLab

•Gitlab Hook

•Gitlab Authentication

•GitLab Logo

干货分享建议收藏:Jenkins集成GitLab

安装完成后重启Jenkins

GitLab为Jenkins生成Token

1.我们使用Jenkins用户登录GitLab 然后使用Jenkins用户创建Token

干货分享建议收藏:Jenkins集成GitLab

2.复制创建的Token

3.打开Jenkins 系统管理——》系统配置

干货分享建议收藏:Jenkins集成GitLab

输入以下相关内容

干货分享建议收藏:Jenkins集成GitLab

选择凭证,测试后保存

4.查看凭证 现在有以下两种方式与GitLab进行认证

•通过GitLab上Jenkins用户的密钥(GitLab绑定Jenkins用户的公钥,Jenkins绑定GitLab上Jenkins用户的私钥)、

•通过GitLab上Jenkins用户的API Token绑定到Jenkins上的GitLab authentication插件上进行连接。
Jenkins构建流水线
创建Project 新建任务——》流水线

2.选择流水线语法

干货分享建议收藏:Jenkins集成GitLab

3.生成流水线脚本

干货分享建议收藏:Jenkins集成GitLab

复制生成的git脚本

4.编写Pipline脚本 我这里脚本如下

node {
    stage('拉取代码'){
        git credentialsId: 'b907af22-5a74-4eee-aa5f-a822c764279c', url: 'git@172.19.95.139:dev01/sample.git'
        echo "Code Pull"
    }
    stage('代码扫描'){
        echo "Code Scanning"
    }
    stage('代码构建'){
        echo "Code Build"
    }
    stage('是否部署'){
        input '是否部署'
    }    
    stage('开始部署'){
        sh '/opt/jenkins/sample/sample_release.sh'
    }
}

将以上脚本写流水线中

干货分享建议收藏:Jenkins集成GitLab

上面脚本最后执行了/opt/jenkins/sample/sample_release.sh脚本,我们到执行任务的Jenkins服务器上去编写这个部署脚本。脚本如下:jenkins服务器将/usr/local/src/sample.zip文件拷贝到了172.19.182.107上

[root@jenkins /]# cat /opt/jenkins/sample/sample_release.sh
#!/usr/bin/env bash

scp /usr/local/src/sample.zip root@172.19.182.107:/usr/local/

这里我们需要先让Jenkins服务器与172.19.182.107做免密登录,将Jenkins的公钥拷贝到172.19.182.107服务中的/root/.ssh/authorized_keys文件中

#Jenkins的公钥(这里为root的公钥,Jenkins进程就需要用root用户运行)
[root@jenkins /]# cat /root/.ssh/id_rsa.pub
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQC7ckQQf4N93Rjf0ts3Lk4siL6FZmZiBiB+ouwTgw9kKof2NeJTguf0aNfDsgSEet4+bJ53ZKztsFZE/C+sqk7grqeLeYDFBWgdZBz1dmCYT51tRFmZPDEDclOIMc2tz0G50g6DFA1dvIfkzeVbKjBNN0o80FSAwAzrtjMrkyaDcrOmYekiSPM8JYJTTcFLCzIBXz7SXOmKH5vyoAIVpdcwnIhkHNLKfD0MdzGb7Kz/pKMnLubodcxyNir6fqw76qwMe1DE0NtQzpaCrTYhVnAizVqCDek0GMZjTG1vWYNn6a8G7omV3Gde1XjcmjAj6ftVQiVLBRJaIGKI4R/B//nd root@jenkins

#测试免密登录
[root@jenkins /]# ssh root@172.19.182.107
