IPv6 networking

[disbelief]

Hi I'm new to Kamal, but I was pretty surprised it doesn't appear to support IPv6 out of the box.

I saw a couple PRs that attempted to address this but neither were merged.

I'm wondering what is the best way to enable IPv6 (and IPv4) for a container, starting with a default kamal network configuration? I see that there is a network accessory but the docs are rather threadbare:

My specific requirements is a container that can use both IPv4 and IPv6, and is able to connect to external services via IPv6 (Supabase).

As @frenkel mentions here, it's possible to create an ipv6 network for the container before deploying: #1381 (comment)

As someone who is a novice with docker and new to kamal I'll have to learn both tools better to figure out how to accomplish this.

I'm assuming it means issuing the docker network create --ipv6 mynetworkname command with the correct ipv6 configuration, and then setting network: mynetworkname in deploy.yml, or naming this manually-created network kamal. The latter sounds simpler but I'd be worried my custom configuration doesn't match what kamal is expecting to operate normally.

Yes, just create a kamal network with these ipv6 settings. It doesn't conflict with the working of kamal, I've been using this in productions for multiple months.
