k8s的rbac 授权
1.认证(Authenticating)是对客户端的认证,通俗点就是用户名密码验证
2.授权(Authorization)是对资源的授权,k8s 中的资源无非是容器,最终其实就是容器的计算,网络,存储资源,当一个请求经过认证后,需要访问某一个资源(比如创建一个 pod),授权检查会根据授权规则判定该资源(比如某 namespace 下的 pod)是否是该客户可访问的。
3.准入(Admission Control)机制:
准入控制器(Admission Controller)位于 API Server 中,在对象被持久化之前,准入控制器拦截对 API Server 的请求,一般用来做身份验证和授权。其中包含两个特殊的控制器:MutatingAdmissionWebhook 和 ValidatingAdmissionWebhook。分别作为配置的变异和验
证准入控制 webhook。
变更(Mutating)准入控制:修改请求的对象
验证(Validating)准入控制:验证请求的对象
准入控制器是在 API Server 的启动参数配置的。一个准入控制器可能属于以上两者中的一种,也可能两者都属于。当请求到达 API Server 的时候首先执行变更准入控制,然后再执行验证准入控制。
在部署 Kubernetes 集群的时候都会默认开启一系列准入控制器,如果没有设置这些准入控制器的话可以说你的 Kubernetes 集群就是在裸奔,应该只有集群管理员可以修改集群的准入控制器。
会默认开启如下的准入控制器。
--admissioncontrol=ServiceAccount,NamespaceLifecycle,NamespaceExists,LimitRanger,ResourceQuota,MutatingAdmissionWebhook,ValidatingAdmissionWebhook
k8s 的整体架构也是一个微服务的架构,所有的请求都是通过一个 GateWay,也就是 kubeapiserver 这个组件(对外提供 REST 服务),k8s 中客户端有两类,一种是普通用户,一种是集群内的 Pod,这两种客户端的认证机制略有不同,但无论是哪一种,都需要依次经过认证,授权,准入这三个机制
认证
1、认证支持多种插件
(1)令牌(token)认证:双方有一个共享密钥,服务器上先创建一个密码下来,客户端登陆的时候拿这个密码登陆即可,这个就是对称密钥认证方式;k8s 提供了一个 restful 风格的接口,它的所有服务都是通过 http 协议提供的,因此认证信息只能经由 http 协议的认证首部进行传递,这种认证首部进行传递通常叫做令牌;
(2)ssl 认证:对于 k8s 访问来讲,ssl 认证能让客户端确认服务器的认证身份,我们在跟服务器通信的时候,需要服务器发过来一个证书,我们需要确认这个证书是不是 ca 签署的,如果是我们认可的 ca 签署的,里面的 subj 信息与我们访问的目标主机信息保持一致,没有问题,那么我们就认为服务器的身份得到认证了,k8s 中最重要的是服务器还需要认证客户端的信息,kubectl 也应该有一个证书,这个证书也是 server 所认可的 ca 签署的证书,双方需要互相认证,实现加密通信,这就是 ssl 认证。
2、kubernetes 上的账号
kubectl explain pods.spec 可以看到有一个字段 serviceAccountName(服务账号名称),这个就是我们 pod 连接 apiserver 时使用的账号,因此整个 kubernetes 集群中的账号有两类,ServiceAccount(服务账号),User account(用户账号)
User account:实实在在现实中的人,人可以登陆的账号,客户端想要对 apiserver 发起请求,apiserver 要识别这个客户端是否有请求的权限,那么不同的用户就会有不同的权限,靠用户账号表示,叫做 usernameServiceAccount:方便 Pod 里面的进程调用 Kubernetes API 或其他外部服务而设计的,是kubernetes 中的一种资源sa 账号:登陆 dashboard 使用的账号user account:这个是登陆 k8s 物理机器的用户
1.ServiceAccount
Service account 是为了方便 Pod 里面的进程调用 Kubernetes API 或其他外部服务而设计的。它与 User account 不同,User account 是为人设计的,而 service account 则是为 Pod 中的进程调用 Kubernetes API 而设计;User account 是跨 namespace 的,而 service account 则是仅局限它所在的 namespace;每个 namespace 都会自动创建一个 default service account;开启 ServiceAccount Admission Controller 后
1)每个 Pod 在创建后都会自动设置 spec.serviceAccount 为 default(除非指定了其他ServiceAccout)
2)验证 Pod 引用的 service account 已经存在,否则拒绝创建;

上面我们说了两个角色绑定:
(1)用户通过 rolebinding 绑定 role
(2)用户通过 clusterrolebinding 绑定 clusterrole
还有一种:rolebinding 绑定 clusterrole rolebinding 绑定 clusterrole 的好处:
假如有 6 个名称空间,每个名称空间的用户都需要对自己的名称空间有管理员权限,那么需要定义 6个 role 和 rolebinding,然后依次绑定,如果名称空间更多,我们需要定义更多的 role,这个是很麻烦的,所以我们引入 clusterrole,定义一个 clusterrole,对 clusterrole 授予所有权限,然后用户通过 rolebinding 绑定到 clusterrole,就会拥有自己名称空间的管理员权限了
