port forward on windows

a) port forward

https://woshub.com/port-forwarding-in-windows/

PS C:\Windows\system32> netsh interface portproxy add v4tov4 listenaddress=192.168.1.100 listenport=6443 connectaddress=172.17.222.29 connectport=6443

PS C:\Windows\system32> netstat -na| find "“6443""

TCP 192.168.1.100:6443 0.0.0.0:0 LISTENING

ubuntu@k3s-master:~$ sudo systemctl stop k3s

ubuntu@k3s-master:~$ sudo k3s server –tls-san 192.168.1.100

b) allow firewall

https://www.howtogeek.com/394735/how-do-i-open-a-port-on-windows-firewall/

Windows Defender Firewall -> advanced -> new rule

  • port
  • TCP
  • specific local ports: 6443
  • Allow the connection
  • Domain + private + public
  • name: kubectl tcp

reinstall everything to fix kubectl TLS/SHH errors

https://github.com/k3s-io/k3s/issues/1381#issuecomment-582291774

curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC=”–tls-san x.x.x.x" sh -s -

1) launch instance

PS C:\Users\Tjen.kube> multipass launch -c 1 -m 1G -d 4G -n k3s-master lts

Launched: k3s-master

2) install k3s with san IP

multipass exec k3s-master -- bash -c "curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="--tls-san 192.168.1.100" sh -"

~~PS C:\Users\Tjen.kube> ~~multipass exec k3s-master -- bash -c "curl -sfL https://get.k3s.io | INSTALL_K3S_EXEC="–tls-san 192.168.1.100" sh -"

-> didn’t work, went in with shell and did the curl straight

improved with baeldung https://www.baeldung.com/ops/k3s-getting-started#1-installation

multipass exec k3s-master -- bash -c "curl -sfL https://get.k3s.io | sh -s - --tls-san 192.168.1.100"

3a) get IP

$IP=multipass info k3s-master | findstr "IPv4:" | Foreach {($_ -split '\s+',4)[1]}

3b) open firewall on port

PS C:\Windows\system32>netsh advfirewall firewall add rule name="kube Open Port 6443" dir=in action=allow protocol=TCP localport=6443

3c) setup port-forwarding (assuming firewall allows port already)

3d) confirm if working

PS C:\Windows\system32> netstat -ano | findstr :6443

4) setup kubectl

PS C:\Users\Tjen.kube> multipass exec k3s-master -- bash -c "sudo k3s kubectl config view --raw" > ~/.kube/config

notepad ~/.kube/config <tab> and replace 127.0.0.1 -> 192.168.1.100

or with 192.168.1.100 to confirm port-forwarding works (and be more robust against reboot)
