$ nmcli device wifi connect wlan_ssid password your_password
$ nmcli --ask conn up id wlan_ssid

$ nmcli dev list | grep -i dns
On Ubuntu 16.04, first list all the connections:
$ nmcli con show NAME UUID TYPE DEVICE docker0 19d065fc-b97f-4421-b839-127d95c07c51 bridge docker0
Then list the settings of one connection:
$ nmcli con show docker0 | grep -i dns
