在Jenkins插件管理中搜索GitLab插件进行安装。
进入Jenkins项目配置里的构建触发器,勾选如下选项:
从系统管理->系统配置->Gitlab将验证去掉,生产最好配置保证安全。
如果是GitLab和Jenkins在同一台服务器,需要开启允许请求发送到本地网络
Admin Area->Settings->Network
把Allow requests to the local network from webhooks and integrations选项勾上,如下:
在Gitlab中,配置Settings->Webhooks,其中URL填写步骤2中的GitLab webhook URL对应的值,并且勾选Trigger下的Push evetns选项,并指定推送分支,例如dev。
接着点击最下方的Add webhook按钮
如下在Gitlab的Webhook下方点击Test按钮的Push event触发Jenkins构建操作。
到Jenkins里可以看到触发了构建
修改dev分支的代码,并提交,可以在Jenkins项目里看到构建
构建完成之后,到Kuboard的容器组里看到,原来的容器下线,新的容器部署。
最后我们请求浏览,如下,至此完成了整个自动化部署。
