Hi, I want to deploy rke2 with dual stack but could not able to find any references for config.yaml. can anyone please share me any reference links of config.yaml for dual stack configuration using calico network. This is the current configuration I am using,

write-kubeconfig-mode: "0644"
tls-san:
  - "<http://master.167.254.204.58.nip.io|master.167.254.204.58.nip.io>"
node-label:
  - "nodetype=master"
cluster-cidr: "10.42.0.0/16"
service-cidr: "10.43.0.0/16"
cluster-dns: "10.43.0.10"
cluster-domain: "<http://master.xxx.xxx.xxx.xxx.nip.io|master.xxx.xxx.xxx.xxx.nip.io>"
cni:
  - calico
disable:
  - rke2-canal
  - rke2-kube-proxy

That looks fine. You just need to also specify ipv6 addresses for everything. What sort of problem are you running into?

The "calico-system" pods are going into "CrashLoopBackOff" if I add the ipv6 addresses for "cluster-cidr" & "service-cidr" fields as below,

cluster-cidr: "10.42.0.0/16,2001:cafe:42:0::/56"
service-cidr: "10.43.0.0/16,2001:cafe:42:1::/112"

I came across this github link that uses multiple fields like "node-ip", "kube-apiserver-arg" & "kube-controller-manager-arg", https://github.com/rancher/rke2/issues/870 Kindly let me know if I need to add any of those fields in "config.yaml" files of both server and agent nodes.

You should also specify a dual-stack node-ip

I hope "node-ip" should be assigned with IPV4 and IPV6 addresses of the host, am I correct?

yes

should this be added in the config.yaml file of both server and agent configurations?

let me give you an example

Thanks much for the detailed explanation @bland-account-99790

Example for agent:

server: "<https://10.0.10.40:9345>"
token: "secret"
node-ip: 10.0.10.41,2a05:d111:c6f:4a99:e30:945e:a70f:717e
