gerar token de painel Kubernetes
There are two ways. When you deploy the manifest originally, this can be done by modifying the Container Args to include this directive: --token-ttl=43200 where 43200 is the number of seconds you want to set the automatic timeout to be.
If you want to manipulate the configuration post-deployment, then you can edit the existing deployment which will trigger the pod to be redeployed with the new arguments. To do this run kubectl edit deployment -n kube-system kubernetes-dashboard and add the argument mentioned above to the args section.
EDIT: If you are using V2 of the Dashboard (Still in beta) then you will need to change the namespace in the command from kube-system to kubernetes-dashboard. (Or somewhere else if you customized it)
EDIT2: You can also set token-ttl to 0 to disable timeouts entirely.
