- For the linkerd-control-plane chart added the values.yaml entry `disableIPv6`, defaulting to false. If we wan't to explicitly set `disableIPv6=true`, the proxy-init v2.3.0 (containing linkerd/linkerd2-proxy-init#350) needs to be used, otherwise proxy-init will error out because of the unknown flag. - For the linkerd2-cni chart added the entries `iptablesMode` (defaults to "legacy") and `disableIPv6` (defaults to false). These flags can still be passed to the current proxy-init version (without linkerd/linkerd2-proxy-init#350) and will simply be ignored. Note this allows routing IPv6 traffic to the proxy by default, but it's just the first step towards IPv6/dual-stack support. More control plane and proxy changes will come next.

I've refactored this so that it remains fully compatible the current proxy-init (v2.2.4) and updated the description above accordingly. |
