How to make nodes in Ready status?

[kenorb]

After applying role, my node has NotReady status and it shows 0 limits for CPU and 170MB for memory.
How I can make my node in Ready state? Maybe it's due to the CPU or memory limits?

$ kubectl describe node mynode | tail -n10
...

Config:

---
- hosts: vm01
  roles:
    - role: xanmanning.k3s
      vars:
        k3s_become_for_all: true
        k3s_etcd_datastore: yes
        k3s_server:
          disable:
            - coredns
            - local-storage
            - metrics-server
            - servicelb
            - traefik
          flannel-backend: 'none'
          write-kubeconfig-mode: 640
        k3s_state: installed

Other info:

local$ ansible-galaxy list xanmanning.k3s
- xanmanning.k3s, v2.11.0
vm01$ grep -E ^cpuset\\s+.*\\s+1$ /proc/cgroups
cpuset	9	4	1
vm01$ grep -E ^memory\\s+.*\\s+1$ /proc/cgroups
memory	12	97	1

In general I think that's the reason why my node is in NotReady state.

First thing, have you applied a CNI? Nodes will not be ready until you have a CNI.

Thanks, it worked after adding:
