Lab exercise 16.2 cannot be completed due to a potentially missing step
While doing lab exercise 16.2 (Authentication and authorization), the below step even after creating a Role and Role binding
kubectl --context=DevDan-context get pods
Error from server (Forbidden): pods is forbidden: User "DevDan"
cannot list pods in the namespace "development"
Any clues?
Thanks,
Niti

Hello,
If you are on step 9, as the directions note, you shoud expect an error. If you have continued on to step 12 and 14 and continue to receive the same error then check that there are no typos in the role-dev.yaml or rolebind.yaml file. After creating each object you should be able to run a get and describe against each and see the expected details, then I would verify that step 5 and 6 ran without error.
I have just run each step from 1 to 15 and they behaved as the book suggests. I am unsure of the issue, but would guess it has to do with YAML.

CURRENT NAME CLUSTER AUTHINFO NAMESPACE**There is no contexts for user DevDan - What am missing here ? **

Hello,
A user's context is not the same as RBAC ability to complete a task. A context is a combination of a user, namespace, and cluster - which RBAC may apply, but does not set the RBAC for that combination. The RBAC settings would be something the cluster admin does, whereas the context is something the user leverages to make it easy to connect and run commands across one or more clusters.

So is this the expected output? or what command will work here to view the context for user=DevDan?
