如何列出我当前的 RBAC 角色和我所属的组？

Question

我已通过 kubernetes 集群的身份验证，如何查看我的 RBAC 角色和附加到我当前帐户的组？

Answer 1

按照以下步骤操作

安装 go 并验证它是否存在

master $ echo $GOPATH
/opt/go

创建并验证

master $ mkdir -p $GOPATH/bin

安装 rakkess

curl -Lo rakkess.gz https://github.com/corneliusweig/rakkess/releases/download/v0.2.0/rakkess-linux-amd64.gz && \
  gunzip rakkess.gz && chmod +x rakkess \
  && mv rakkess $GOPATH/bin/

列出特定命名空间中的权限

rakkess --namespace <namespace-name>

您应该会看到以下格式的输出

master $ rakkess -n kube-system

找到更好的工具

这个工具看起来比 rakkess 好多了
正是我要找的

https://github.com/reactiveops/rbac-lookup

在最简单的用例中，rbac-lookup 将 return 任何匹配的用户、服务帐户或组以及它被赋予的角色。

rbac-lookup rob

SUBJECT                   SCOPE             ROLE
rob@example.com           cluster-wide      ClusterRole/view
rob@example.com           nginx-ingress     ClusterRole/edit
The wide output option includes the kind of subject along with the source role binding.

rbac-lookup ro --output wide

SUBJECT                   SCOPE             ROLE                SOURCE
User/rob@example.com      cluster-wide      ClusterRole/view    ClusterRoleBinding/rob-cluster-view
User/rob@example.com      nginx-ingress     ClusterRole/edit    RoleBinding/rob-edit
User/ron@example.com      web               ClusterRole/edit    RoleBinding/ron-edit
ServiceAccount/rops       infra             ClusterRole/admin   RoleBinding/rops-admin
