作为持续集成的利器Jenkins已经得到了广泛地应用，仅仅作为一个工具，Jenkins已然有了自己的生态圈，支持其的plugin更是超过1300+。在实际中如何使用以及如何更好地使用jenkins，一直是大家在实践并讨论的。本系列文章将会从如何使用jenkins方面对一些细节进行总结和整理，这篇文章将会介绍如何在Jenkins中实现与gitlab的集成

事前准备

只要有jenkins即可，没有的可以使用Jenkins官方的镜像或者安装包，或者使用Easypack中封装的基本一致的Jenkins。

docker pull镜像

[root@liumiaocn ~]# docker pull liumiaocn/jenkins
Using default tag: latest
latest: Pulling from liumiaocn/jenkins
Digest: sha256:87c954f71bc3ce1ba5d001bfbae501f9965368c16f0111ef951350376c2f6832
Status: Image is up to date for liumiaocn/jenkins:latest
[root@liumiaocn ~]#

启动Jenkins镜像
docker run -d -p 8090:8080 -p 50000:50000 –name jenkins liumiaocn/jenkins

[root@liumiaocn ~]# docker run -d -p 8090:8080 -p 50000:50000 --name jenkins liumiaocn/jenkins

[root@liumiaocn ~]#

plugin

与gitlab的集成也是通过插件来做的,需要安装GitLab Plugin插件,目前版本是1.4.6，通过使用这个插件进行集成能够使得gitlab在push之后能够调用jenkins进行构建。详细说明如下图所示

安装

可以使用jenkins的插件管理页面进行安装，也可以使用其id(gitlab-plugin)在镜像中进行安装并重启镜像即可。在mailer中我们也使用了jenkins官方所提供的install-plugins.sh，连同依赖关系一起安装给自定义jenkins会带来极大的方便。

[root@liumiaocn ~]# docker exec -it jenkins sh
/ $ install-plugins.sh gitlab-plugin

插件安装确认

重新启动后确认此插件已经安装完毕

设定内容

系统管理 -> 系统设置处的Gitlab相关内容则为所需设定的内容

认证信息使用Gitlab的API Token的方式进行创建，首先确认一下Gitlab 的ApiToken的相关信息。

gitlab API相关的信息，可以参看：

使用确认到的API Token创建一个Gitlab API Token类型的Crendentials，详细信息如下：

在设定页面选中刚刚创建的Gitlab API Token

验证

设定完毕之后，点击Test Connection便可以确认jenkins和gitlab之间是否通过此插件进行了集成。页面显示Success说明已经OK。

总结

Jenkins与gitlab设定需要下载并安装gitlab-plugin插件，通过创建gitlab api token并使用，便可以通过gitlab-plugin插件提供的测试功能进行集成连接确认。
