背景：当集群node节点故障上面还在运行Pod，贸然关机重启会丢失Pod数据，严重造成节点故障流程：先将该故障节点进行隔离 将运行在该节点的Pod驱逐

简介：添加污点的Node节点默认不会参与日常调度，有两种策略分别为“NoSchedule”和“NoExecute”，加入污点的Node只有在Pod的Yaml文件设置相对应的容忍，Pod才会调度到该节点，但是注意不是NoSchedule：软策略，表示尽量不调度到污点节点上去，只会影响到新的pod而不会对已经运行在该Node节点其他pod造成影响NoExecute：该选项意味着一旦 Taint 生效，如该节点内正在运行的 pod 没有对应 Tolerate 设置，会直接被逐出eg：NoSch.

简介满足项目中多分支任务构建步骤创建多分支流水线job点击保存后它会自动扫描所有分支，并构建

插件名称：Blue Ocean插件管理里安装即可效果图可以看到构建日志代码变化

需要的插件：Gitlab pugin准备：前面创建的Gitlab API Token步骤：1.配置系统的Gitlab地址源系统管理-->系统配置2.配置jenkins中job的触发器3.配置Gitlab上拉，配置成功的话会返回一个200标识，提交代码到master上后观察Jenkin...

思路：可以使用Jenkins中的凭据来管理，Jenkinsfile再调用凭据信息的变量，这样一些私密信息就不会放到Jenkinsfile文件中创建凭据，选择用户名密码类型写好保存后，编写Pipline，在定义变量(environment)这一栏申明，credentials()为定义变量类型为凭据类型... environment { DINGTALK_CREDS = credentials('dingding') }... stages { stag.

步骤：1.安装插件"Multiple SCMs Plugin"系统配置-->插件管理-->可选插件-->Multiple SCMs Plugin2.添加Gitlab凭据先在Gtilab中的Apitoken拷贝下来系统配置-->Manage Credentials-->添加凭据(ID:是你要调用的key API token:是真正的value，上面是token的获取方法)3.开始创建pipline这里选择"流水线"配...
