"netplan" rules to the "ip rule"

[kislik]

Matthias, can you please covert the netplan rules to the debian ip command?
I tried to convert by myself but it does not work.

My initial hetzner and cluster data:

subnet assigned to the vSwitch: 168.168.168.104/29
internal network range for cluster internal communication: 192.168.100.0/24
the default service IP range: 10.96.0.0/12
the Pod IP range: 10.244.0.0/16

My routing table /etc/iproute2/rt_tables:

# cat /etc/iproute2/rt_tables
255     local
254     main
253     default
0       unspec
1       vswitch

The settings that I tried in the /etc/network/interfaces

# cat /etc/network/interfaces
auto enp0s31f6.4000
iface enp0s31f6.4000 inet static
  # UP PRIVATE NETWORK
  address 192.168.100.3
  netmask 255.255.255.0
  vlan-raw-device enp0s31f6
  mtu 1400

  up ip rule add from 168.168.168.104/29 to 10.96.0.0/12 lookup main
  up ip rule add from 168.168.168.104/29 to 10.244.0.0/16 lookup main
  up ip rule add from 168.168.168.104/29 lookup vswitch
  up ip rule add to 10.244.0.0/16 lookup vswitch

  up ip route add default via 168.168.168.105 dev enp0s31f6.4000 onlink table vswitch

Thanks!
