To check your current version issue the following command:
$ ntk sys version 4.2.28
If version is 4.2.xx you can update automatically, you just need to get newer cli tools:
$ docker pull notakey/cfg:4.2.32 $ ntk cfg set cli.image notakey/cfg:4.2.32 $ ntk cli update_wrapper $ ntk sys update
If version is 4.1.xx or older, you have to upgrade your appliance. See Notakey Authentication Server documentation for upgrade instructions.
