End Users - Test Local Access using SSH or Kubernetes CLI

After creating end users, test their access to the the Kubernetes commands / resources and linux access.

• You should already have created at least one end user.
• You need to perform this procedure using an end user.

1. Login to the active controller as an end user, steveenduser in this example.

   Use either a local console or .

2. Test access to linux commands (admin and non-admin) using the following commands:

   # Creating user requires sudo
   
   $ sudo ldapusersetup -u johnsmith
   steveenduser is not allowed to run sudo on controller-0.  This incident will be reported.
   
   # Listing IP interfaces does not require admin privileges
   
   $ ip link show
   1: lo: <LOOPBACK,UP,LOWER_UP> mtu 1500 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000
   link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
   2: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel state UP mode DEFAULT group default qlen 1000
   link/ether 08:00:27:39:06:4e brd ff:ff:ff:ff:ff:ff
   3: enp0s8: <BROADCAST,MULTICAST> mtu 1500 qdisc fq_codel state DOWN mode DEFAULT group default qlen 1000
   link/ether 08:00:27:38:8b:7c brd ff:ff:ff:ff:ff:ff
   ...

3. Test access to kubernetes commands / resources using the following steps:

   1. Use kubeconfig-setup to setup KUBECONFIG for local environment.

      $ kubeconfig-setup
      $ source ~/.profile

   2. Use oidc-auth to authenticate through /.

      $ oidc-auth
      Using "steveenduser" as username.
      Password:
      Successful authentication.
      Updated /home/johnsmith/.kube/config .

   3. Use kubectl to test access to kubernetes commands / resources (admin and non-admin).

      # Displaying anything in 'kube-system' namespace requires 'cluster-admin' privileges
      
      $ kubectl -n kube-system get secrets
      Error from server (Forbidden): secrets is forbidden: User "steveenduser" cannot list resource "secrets" in API group "" in the namespace "kube-system"
      
      # Should be able to display resources in his own namespace, 'ABC-ns'
      
      $ kubectl -n abc-ns get all
      NAME                 TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
      service/kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   3d9h

4. Test access to commands / resources.

   $ source local_starlingxrc
   Enter the password to be used with Keystone user steveenduser:
   Created file /home/johnsmith/steveenduser-openrc
   
   $ system host-list
   Must provide Keystone credentials or user-defined endpoint and token, error was: The request you have made requires authentication. (HTTP 401) (Request-ID: req-0feb292f-d649-4d9f-8e60-f63643265207)
