03/15/2023, 12:47 PMI don't think there is a specific way; just ask what sort of issues you have?
Also, assuming you have looked at the k3s requirements page for OS/Networking? https://docs.k3s.io/installation/requirements

03/15/2023, 12:50 PMcertificates with a dns hook api feels like vacation compared to the ip6 masquerading issues 🙂

03/15/2023, 1:02 PMThat will be a big beer 🙂

03/19/2023, 12:16 PMBasically following the tutorials even more strictly
adamant-pencil-35455
03/19/2023, 12:16 PMHere my setup
adamant-pencil-35455
03/19/2023, 12:17 PMProxmox Server - eth0 has ipv4 and ipv6
adamant-pencil-35455
03/19/2023, 12:17 PMI created a vrbr0 interface - gave it a 10.10.x IP, I also gave it an internal iv6 IP (not one of the official IPs)
adamant-pencil-35455
03/19/2023, 12:18 PMI added masquarading ipv6 (yes that's crazy - but this is how the scripts I created will work in any constellaton with all ip4/ip6 combos)
adamant-pencil-35455
03/19/2023, 12:18 PMthen I created 5 VMs (debian based) assigining a static ip4 and ip6 to all of them
adamant-pencil-35455
03/19/2023, 12:19 PMwget -6 <https://foo>wget -4 <https://foo>adamant-pencil-35455
03/19/2023, 12:19 PMthen I installed k3s - node-ip needs to have the VMs ipv4 and ipv6
adamant-pencil-35455
03/19/2023, 12:20 PMand (!) i added this to the server:
--cluster-cidr=10.42.0.0/16,2001:cafe:42:0::/56--service-cidr=10.43.0.0/16,2001:cafe:42:1::/112--flannel-ipv6-masqadamant-pencil-35455
03/19/2023, 12:21 PMipv4 and ipv6 now work inside of kubernetes

03/19/2023, 12:24 PMHere my test
