Namespaces is forbidden error for a new user - kubernetes

Question

I added a new user named "hello" to kind cluster with client-certificate-data and client-key-data. When I switch to its context and press the command:
kubectl get ns development-hello
I get:
Error from server (Forbidden): namespaces "development-hello" is forbidden: User "hello" cannot get resource "namespaces" in API group "" in the namespace "development-hello"
I do not have clusterrolebinding for this user.
Here is a snapshot from kubectl config view
apiVersion: v1
clusters:
- cluster:
certificate-authority-data: DATA+OMITTED
server: https://127.0.0.1:33445
name: kind-kind
contexts:
- context:
cluster: kind-kind
user: hello
name: hello-kind-kind
- context:
cluster: kind-kind
user: kind-kind
name: kind-kind
current-context: hello-kind-kind
kind: Config
preferences: {}
users:
- name: hello
user:
client-certificate-data: REDACTED
client-key-data: REDACTED
- name: kind-kind
user:
client-certificate-data: REDACTED
client-key-data: REDACTED

Answer 1

A ClusterRole and RoleBinding need to be created for the hello user by using the admin account.
apiVersion: rbac.authorization.k8s.io/v1
kind: ClusterRole
metadata:
name: ns-role
rules:
- apiGroups: [""]
resources: ["namespace"]
verbs: ["get", "watch", "list", "create", "delete"]
---
apiVersion: rbac.authorization.k8s.io/v1
kind: RoleBinding
metadata:
name: ns-rolebinding
namespace: development-hello
subjects:
- kind: User
name: hello
apiGroup: rbac.authorization.k8s.io
roleRef:
kind: ClusterRole
name: ns-role
apiGroup: rbac.authorization.k8s.io
The kubeconfig file with admin account can be retrieved using below command
docker exec -it <kind-control-plane-node-name>
sudo cat /etc/kubernetes/admin.conf

Answer 2

This is how I solved it in my case:
export KUBECONFIG=/etc/kubernetes/admin.conf
