k0s-ansible's Issues

FRE: Systemd template k0s.service.j2 alignment

Recommended: resolve deltas between k0s systemd service file and k0s systemd service file for consistency & experience integrity.

Compare:
A) movd/k0s-ansible systemd template: roles/k0s/initial_controller/templates/k0s.service.j2
B) k0sproject/k0s systemd example: init/k0s.service

Replace k0s.service.j2 template with adoption of new k0s install sub command

Enhancement:

k0s now supports a full featured templating mechanism to write the systemd service file. Recommend adoption of up stream native systemd service file creation strategy.

Relevant code:

up stream template https://github.com/k0sproject/k0s/blob/main/pkg/install/service.go
k0s-ansible template https://github.com/movd/k0s-ansible/blob/main/roles/k0s/initial_controller/templates/k0s.service.j2
k0s-ansible playbook https://github.com/movd/k0s-ansible/blob/main/roles/k0s/initial_controller/tasks/main.yml

Usage:

root@k0s:~# k0s install --help
Helper command for setting up k0s on a brand-new system. Must be run as root (or with sudo)

Usage:
  k0s install [flags]

Flags:
  -h, --help          help for install
      --role string   node role (possible values: server or worker. In a single-node setup, a worker role should be used) (default "server")

Global Flags:
  -c, --config string            config file (default: ./k0s.yaml)
      --data-dir string          Data Directory for k0s (default: /var/lib/k0s). DO NOT CHANGE for an existing setup, things will break!
  -d, --debug                    Debug logging (default: false)
  -l, --logging stringToString   Logging Levels for the different components

Error: unknown flag: --config

Hi,

the role k0s/initial_controller utilizes the command:
k0s token create --role controller --config {{ k0s_config_dir }}/k0s.yaml

It looks like the flag --config is not valid anymore:

$ k0s token create --role worker --config /etc/k0s/k0s.yaml
Error: unknown flag: --config

Tested with: v1.26.0+k0s.0

The flag is not available in the latest documentation:
https://docs.k0sproject.io/v1.26.2+k0s.1/cli/k0s_token_create/

Update:
Same for role k0s/worker
k0s install worker --config {{ k0s_config_dir }}/k0s.yaml --token-file {{ k0s_config_dir }}/worker-token {{ extra_args | default(omit) }}

--config flag was removed: https://docs.k0sproject.io/v1.26.2+k0s.1/cli/k0s_install_worker/

Issues while connecting to nginx deployment in k0s cluster

Hi team,

I am following this document < https://docs.k0sproject.io/v1.23.6+k0s.2/examples/ansible-playbook/ > to create k0s cluster using ansible, on the Linux/AMD64 AWS bare metal instance.

It seems like the k0s cluster got created successfully and all the worker nodes are in ready state:

NAME    STATUS   ROLES    AGE   VERSION       INTERNAL-IP      EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME 
k0s-4   Ready    <none>   10m   v1.22.4+k0s   10.197.110.121   <none>        Ubuntu 22.04.1 LTS   5.15.0-53-generic   containerd://1.5.8 
k0s-5   Ready    <none>   10m   v1.22.4+k0s   10.197.110.251   <none>        Ubuntu 22.04.1 LTS   5.15.0-53-generic   containerd://1.5.8 
k0s-6   Ready    <none>   10m   v1.22.4+k0s   10.197.110.142   <none>        Ubuntu 22.04.1 LTS   5.15.0-53-generic   containerd://1.5.8 
k0s-7   Ready    <none>   10m   v1.22.4+k0s   10.197.110.104   <none>        Ubuntu 22.04.1 LTS   5.15.0-53-generic   containerd://1.5.8

Then I created nginx deployment with 5 replicas and that seems to work as well:

NAME    READY   UP-TO-DATE   AVAILABLE   AGE 
nginx   5/5     5            5           64s

I exposed nginx port 80 to 8100 as mentioned in the docs:

$ kubectl expose deployment nginx --target-port=80 --port=8100 
service/nginx exposed

But I get no response from nginx deployment when I wget it from busybox.

$ kubectl run hello-k0s --image=quay.io/prometheus/busybox --rm -it --restart=Never --command -- wget -qO- nginx:8100 

pod "hello-k0s" deleted 
Error from server: Get "https://10.197.110.121:10250/containerLogs/default/hello-k0s/hello-k0s": dial timeout, backstop

I even mentioned port 80 (--port=80) while creating nginx deployment using kubectl, but that didn’t help.
Instead of busybox, I tried using ubuntu image, but the results are the same.

Can you please provide me with some pointers here?
