Describe the bug:
Pods from default addons cannot connect to
https://10.43.0.1:443
.Steps To Reproduce:
Expected behavior:
All default addons from
/var/lib/rancher/k3s/server/manifests
should be up and running. If any iptables extension is missing it should be catched by check-config.sh script.Actual behavior:
coredns
pod never reaches ready staus.local-path-provisioner
andmetrics-server
pods enterCrashLoopBackOff
status. All the failing pods show an error related to unable to connect tohttps://10.43.0.1:443
. Server logs mention some iptables extension as missing.Additional context / logs:
My system has a lot of iptables rules but for the sake of simplicity I have reproduced the issue with a firewall withot any rule and with a permissive default policy. These are all the steps I followed:
Install K3s from official Getoo repository
Check if there are any kernel options missing ...
Disable firewall (default policy allows all traffic)
Start K3s server
Check iptables rules added by K3s ...
Check pod status
Check failing pods logs
coredns pod ...
local-path-provisioner pod ...
local-path-provisioner pod ...
