问题
官方给出的2核4g的最低配置实际无法正常使用all-in-one安装，我感觉可以删掉改为4核8G，以免导致更多人反复来问问题，另外devops组件中 devops-jenkins 的默认最高内存2g似乎不够用，导致devops-jenkins pod不断自动重启。

以下是我一点一点解决问题的过程,希望其他朋友看了也能有用

一开始我看官方建议最低配置为2CPU, 4G，但是发现使用all-in-one安装后连基本的服务跑起来都困难，不断有pod event报cpu不够用，按官方开启Devops组件文章操作，通过修改资源定义yaml中 devops选项，将false改为true，系统CPU飙升一段时间后，系统组件中并没有出现devops组件的页签。

于是我使用了一台8核16g的机器来测试，这次全程顺畅，devops也能正常安装上，所有pod都正常运行

接着创建devops流水线，但无法运行，我里边只放了一个最简单的 拉取代码步骤。

每次一旦运行任务 devops-jenkins 和 devops-jenkins-agent两个pod就会变异常自动重启

我查看了devops-jenkins的YAML文件，默认配置的内存1500Mi、CPU100m，我猜测可能是因为小了导致不断重启，于是我修改了配置，改为8GB内存、 4CPU，于是就再没有自动重启的情况发生了.

查看监控，发现devops-jenkins在没有运行任务的情况下，都至少2GB以上的内存，CPU为0.4核心，所以感觉其他朋友至少修改为3GB，1核心才够devops-jenkins使用。

使用图形创建流水线的界面我怎么没有看见呢，请指教下
