How to change a users cluster-permissions with custom RBAC
Managing users' cluster-permissions with custom RBAC
If you want to give a user access to your cluster, you must first add the user to your organisation. Refer to Invite a user to an organisation.
By default, some organisation roles already have clusterRoles assigned to them, as you can see in the table below. However, if you want to give a user with a certain role extra permissions within your cluster, you can do so by adding custom RBAC-rules.

Adding custom RBAC-rules
Now that the user has been added to your organisation, the user is able to connect to a cluster using kubectl. You can add a custom
clusterRoleBinding resource to assign additional permissions for the user within the cluster.
Customize the example below and apply it with kubectl apply, alternatively you can add it to your git-repository and deploy is using GitOps through Fluxcd or other Continuous deployment tooling continuous deployment.
