环境准备
Jenkins
安装插件：
- Blue Ocean
- Build With Parameters
- Basic Branch Build Strategies Plugin
- ??????Git Parameter Plug-In
- GitLab Plugin
- Git plugin
- Gradle Plugin
- Kubernetes plugin
- ThinBackup
安装好Kubernetes plugin后，配置Kubernetes，我们的构建全部是放在k8s里面做的，可以做到多编译环境灵活切换以及提升jenkins效率。
这里建议关闭https证书检查，避免不必要的麻烦。
还有一定要使用admin.conf放入凭据里，防止权限不够，创建不了pod
Gitlab
推荐直接使用docker安装：Docker GitLab by sameersbn
当然你也可以直接使用Google的gitlab
JFrog Container Registry
docker安装：
docker pull docker.bintray.io/jfrog/artifactory-jcr:latest
docker run --name artifactory-jcr \
-d \
-v /app/jfrog/artifactory:/var/opt/jfrog/artifactory \
-p 8081:8081 -p 8082:8082 \
--privileged=true \
docker.bintray.io/jfrog/artifactory-jcr:latest项目CI/CD配置
示例项目
Jenkins 配置
创建一个多分支流水线任务
对于一般项目，直接使用pipline即可。这里使用多分支流水线，考虑的是一个git仓库里面有多个子项目需要单独构建的复杂场景。
分支源设置
设置触发自动集成规则
这里我们要根据打好的tag去自动集成，所以需要设置自动发现tag，以及build strategies里面的 tag触发规则
设置git仓库中Jenkins pipline文件的位置?
?设置Jenkins 扫描规则
?这里采用Jenkins Scan的方式去拉取git仓库信息，你也可以设置为webhook。
