IPv4 and IPv6 Dual-stack config
If you need to run your K3S cluster with both IPv4 and IPv6 address ranges
you will need to configure the k3s_server.cluster-cidr
and
k3s_server.service-cidr
values specifying both ranges.
✋ if you are using k3s<1.23
you will need to use a different CNI as
dual-stack support is not available in Flannel.
Below is a noddy example:
---
k3s_server:
# Using Calico on k3s<1.23 so Flannel needs to be disabled.
flannel-backend: 'none'
# Format: ipv4/cidr,ipv6/cidr
cluster-cidr: 10.42.0.0/16,fc00:a0::/64
service-cidr: 10.43.0.0/16,fc00:a1::/64
