【开发⼯具】Jenkins+Gitlab实现⾃动化部署
我在尝试在容器中安装Jenkins时，初衷是希望使⽤docker in docker 的模式来实现Jenkins slave容器按需创建。在实现的时候需要在Jenkins 中安装Kubernetes插件。
kubernetes的插件⽬前来看存在⼀个Bug，这个bug很⼩但是会导致我们⽆法设置和kubernetes mastert认证的机制。Bug是由于配置代理时候是⽤的IP 地址，但是jenkins必须加⼊http协议，可惜的是加⼊http协议后更新的代理⼜不能使⽤了，进⼊这种死循环了。所以这种⽅案暂时搁置。
我在写这篇⽂章的时候，Jenkins X 还没有出来。。。⽬前Jenkins 是拥抱了K8S；我认为CI CD环境容器化编排是⼤趋势。
⼀些实践
搭建过基于K8S的完整的平台，写了系列的⽂章总结。有些⼩的团队或者独⽴开发者，单独⼀个Jenkins和Gitlab就⾜够做编译⾃动化了。
So，这⾥我会写常⽤的实现⾃动化部署的⽅案之Jenkins+Gitlab这种模式，在⼩型的开发时候完全够⽤了，从来没有⼀致的最佳⽅案，只有适不适合咱们的团队⽅案。
Jenkins的安装 - 官⽹
To u this repository, run the following command:
sudo wget -O /pos.po pkg.jenkins.io/po
sudo rpm --import pkg.jenkins.io/redhat-stable/jenkins.io.key
If you've previously imported the key from Jenkins, the "rpm --import" will fail becau you already have a key. Plea ignore that and move on.
You will need to explicitly install a Java runtime environment, becau Oracle's Java RPMs are incorrect and fail to register as providing a java dependency. Thus, adding an explicit dependency requirement on Java would force installation of the OpenJDK JVM.
2.54 (2017-04) and newer: Java 8
1.612 (2015-05) and newer: Java 7
With that t up, the Jenkins package can be installed with:
yum install jenkins
See Wiki for more information, including how Jenkins is run and where the configuration is stored, etc.
Gitlab的安装
⾃⼰⽹上找吧，但是安装8.0+的版本，因为后⾯webhooks是有版本的要求的。
⾃动化部署配置
创建普通编译Job
Jenkins创建⼀个Job，并配置git信息
注意，这⾥连接Gitlab需要配置认证
frosted同时，保证jenkins机器安装了Java， maven。
Maven 中需要配置成我们⾃⼰的仓库，配置即可。
[root@jenkins ~]# find / -l
/etc/l
/var/lib/jenkins/.l
/usr/share/maven/l
[root@jenkins ~]# cat /usr/share/maven/l
更改成公司artificatory配置

加⼊CI Trigger功能
Jenkins Trigger配置
Gitlab配置webhook
测试webhook：
加⼊CD功能
⾃动化运⾏脚本编写
[root@jenkins ~]# cat run.sh
#!/bin/bash
echo 'Checking scic document '
SCIC_APP_PID=$(ps -ef | grep scic_paas_doc | grep -v grep | awk '{ print $2 }')
if [ -z "$SCIC_APP_PID" ]
then
echo Starting
nohup java -jar scic_paas_doc-0.0.1-RELEASE.jar > doc.log 2>&1 &
echo Started successfully.
el
echo killing old rvice - $SCIC_APP_PID ...
kill $SCIC_APP_PID
echo Restarting
nohup java -jar scic_paas_doc-0.0.1-RELEASE.jar > doc.log 2>&1 &
echo Restarted successfully.
fi
Global配置SSH Server
Build Job中配置PostBuild，Over SSH
通过SSH上传jar，并使⽤脚本运⾏
