User Management

Adding a Cluster User

To add a user to the cluster, use the kubeconfig create command. This will output a kubeconfig for the user, which can be used for authentication.

On the controller, run the following to generate a kubeconfig for a user:

$ k0s kubeconfig create [username]

Enabling Access to Cluster Resources

To allow the user access to the cluster, the user needs to be created with the system:masters group:

$ k0s kubeconfig create --groups "system:masters" testUser > k0s.config

Create a roleBinding to grant the user access to the resources:

$ k0s kubectl create clusterrolebinding --kubeconfig k0s.config testUser-admin-binding --clusterrole=admin --user=testUser
