hard time installing kubernetes distributions in defualt image (k3s / k0s) #26

Closed lonerkim closed 6 months ago

lonerkim commented 8 months ago

When I tried to k0s install and start services, this happened

Error: pre-flight checks failed, check out `k0s sysinfo`: lookup localhost on 8.8.8.8:53: no such host

so I tried to edit my /etc/hosts to include 

127.0.0.1       localhost lpi3h-c6dd
::1             localhost ip6-localhost ip6-loopback

and service starts

but then when I tried to join my worker nodes, below happened.

root@lpi3h-(devicename)~# sudo k0s worker "mytoken"
Error: pre-flight checks failed, check out `k0s sysinfo`: failed to load/attach eBPF device filter program: load ext_infos: detect support for Program BTF (func/line_info): detect support for BTF: function not implemented

Error: sysinfo failed

so I tried other distribution (k3s)

and this happened

iptables-restore/1.8.10 (nf_tables) Failed to initialize nft: Protocol not supported

so I tried

update-alternatives --set iptables /usr/sbin/iptables-legacy
update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
update-alternatives --set arptables /usr/sbin/arptables-legacy
update-alternatives --set ebtables /usr/sbin/ebtables-legacy
=========================================
update-alternatives: using /usr/sbin/iptables-legacy to provide /usr/sbin/iptables (iptables) in manual mode

update-alternatives: error: alternative /usr/sbin/arptables-legacy for arptables not registered; not setting
update-alternatives: error: alternative /usr/sbin/ebtables-legacy for ebtables not registered; not setting

it seems can start a service at first, but when I checked status

also when I checked br_netfilter / overlay myself

root@lpi3h-(devicename):~# sudo modprobe br_netfilter sudo modprobe overlay
modprobe: FATAL: Module br_netfilter not found in directory /lib/modules/6.7.0-rc3+
modprobe: FATAL: Module overlay not found in directory /lib/modules/6.7.0-rc3+

this came out. br_netfilter and overlay / eBPF, BTF is not supported I guess?

You can check this pr #27 to enable some kernel configs.

k3s is running on LonganPi 3H Ubuntu-CLI addtional configs I tried on

seems there isn't signifiacnt issue for now, I'll mark this issues as cloesed. thanks for help.
