How to list my current RBAC roles and groups I belong to?

Question

I authenticated to kubernetes cluster, how can I view my RBAC roles and groups attached to my current account?

Answer 1

Maybe you meant?

kubectl get role -o yaml
kubectl get rolebinding -o yaml

Answer 2

Found better tool

this tool looks way better than rakkess
exactly what I was looking for

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

In the simplest use case, rbac-lookup will return any matching user, service account, or group along with the roles it has been given.

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

Follow the below steps

1. Install go and verify that it is present

master $ echo $GOPATH
/opt/go

2. Create and Verify

master $ mkdir -p $GOPATH/bin

3. Install 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/

4. List the privileges in a specific namespace

rakkess --namespace <namespace-name>

5. You should see the output in the below format

master $ rakkess -n kube-system
NAME                                            LIST  CREATE  UPDATE  DELETE
