SOLVED Kubernetes does not start after having defined the Apps pool

[ebatsin]

I'm new to TrueNAS and my use case requires using docker containers so I went to Scale instead of Core but I have trouble setting up kubernetes.

On a fresh install, after having set up my network and created my pools and set up my shares I went to the "Apps" tab.

Here it asked me for a pool to store apps data on and then I got an error:

FAILED
[EINVAL] kubernetes_update.route_v4_gateway: Please set a default route for system or for kubernetes. [EINVAL] kubernetes_update.route_v4_interface: Please set a default route for system or specify default interface to be used for kubernetes.

Complete error in spoiler:

I thought by default there would be a "local" kubernetes that starts and use my NAS as one node but it does not seem to work that way.

I found the settings for kubernetes but I do not know what to set in Cluster CIDR, Service CIDR, Cluster DNS IP (since I only want my dockers to run on my NAS).

Could you explain what I missed or point me to some documentation that could help me fix this issue?

Nervermind, forgot to put a gateway route. I can't delete the original post while it is awaiting approval it seems.
