[QUESTION/HELP] Starting k3d with dual stack ipv6 enabled

[mgazza]

Question / Where do you need Help?

Hi, I need instructions for getting dual stack ipv4/v6 enabled.

I have tried switching from flannel to calico which works however when providing --cluster-cidr and --service-cidr I receive an error.

WARN[0009] warning: encountered fatal log from node k3d-tilt-server-0 (retrying 9/10): �time="2022-12-05T16:01:24Z" level=fatal msg="cluster-cidr: [10.42.0.0/16 2c06:25:f1cd:11:10::/80] and node-ip: [172.25.0.3], must share the same IP version (IPv4, IPv6 or dual-stack)" 

then adding the following

      - arg: --node-ip=172.17.0.1,2c06:25:f1cd:11:50::20
        nodeFilters:
          - server:0

results in the agent giving the same error

WARN[0041] warning: encountered fatal log from node k3d-tilt-agent-0 (retrying 7/10): �time="2022-12-05T16:02:35Z" level=fatal msg="cluster-cidr: [10.42.0.0/16 2c06:25:f1cd:11:10::/80] and node-ip: [172.26.0.4], must share the same IP version (IPv4, IPv6 or dual-stack)" 

so adding the agent

      - arg: --node-ip=172.17.0.2,2c06:25:f1cd:11:50::21
        nodeFilters:
          - agent:0

and get the error

WARN[0940] warning: encountered fatal log from node k3d-tilt-agent-0 (retrying 0/10): <time="2022-12-05T16:19:05Z" level=fatal msg="Kubelet failed to wait for apiserver ready: timed out waiting for the condition, failed to get apiserver /readyz status: Get \"https://127.0.0.1:6444/readyz\": read tcp 127.0.0.1:43886->127.0.0.1:6444: read: connection reset by peer - error from a previous attempt: EOF"
