title: Use one users for multiple Rolebindings in Kubernetes
body: <p>I have an application that is going to monitor and if necessary scale other resources. At the moment I am using the cluster-admin tokens for it to access the k8s api but I want to limit its access to just monitor and scale.</p>
  
  <p>I know that I need to use Role and Rolebinding for this but I have two questions:</p>
  
  <ol>
  <li><p>Can I use just one user and bind it to a role in different namespaces? I need to run multiple instances of my application in different namespaces on a cluster</p></li>
  <li><p>Is there a way to create a new k8s user via yaml file and use that to bind the role?</p></li>
  </ol>
  
  <p>At the end if I am using a wrong approach please let me know because I am somehow newbie in RBAC.</p>
