什么是RBAC
基于角色的访问控制（Role-based access control，简称 RBAC），指的是通过用户的角色（Role）授权其相关权限，这实现了更灵活的访问控制，相比直接授予用户权限，要更加简单、高效、可扩展。
当使用 RBAC 时，通过分析系统用户的实际情况，基于共同的职责和需求，授予他们不同角色。你可以授予给用户一个或多个角色，每个角色具有一个或多个权限，这种 用户-角色、角色-权限 间的关系，让我们可以不用再单独管理单个用户，用户从授予的角色里面继承所需的权限。
大家可以看一下的案例更容易理解：
用户角色分为管理员、开发、运维，各个角色并具备不同的权限。每个用户也具备单个与多个角色。
需求说明
本章节是通过一个企业案例进行讲解，需求如下：
接下来，我们根据上图的组织架构来创建用户与组。
Jenkins权限如何分配：
开发组：只读权限
运维组：管理员权限
测试组：执行权限
配置权限
配置角色
分配权限
权限验证
张三（管理员），下图可以看到什么权限都有：
李四（只读），下图可以看到只有只读权限：
张三（执行权限），下图可以看到是有执行权限的：
配置Pipeline权限
需求说明
实际情况中，我们是通过Pipeline进行管理流水线的，接下来咱们针对Pipeline进行配置权限控制，详情如下图：
权限配置：
运维组：管理员权限
开发组：非生产环境只读权限
测试组：非生产环境执行权限
权限配置
以Ruoyi- Gateway为例，在Pipeline里配置权限：
