chore(main): release v1.37.0

[hcloud-bot]

IPv6 ExternalIP

We derive the IPv6 ExternalIP of a Node from the IPv6 subnet the server reports, by using the first address of that subnet. This is wrong for servers that use a different address out of their subnet, and Robot does not report a subnet for every server, in which case the Node got no IPv6 ExternalIP at all. You can now set the address explicitly through the Node annotation instance.hetzner.cloud/external-ipv6:

kubectl annotate node $NODE_NAME --overwrite \
  instance.hetzner.cloud/external-ipv6=2001:db8:1234::5

The annotation works for Cloud and Robot servers and takes precedence over the derived address. It requires IPv6 to be enabled for Node addresses via HCLOUD_INSTANCES_ADDRESS_FAMILY.

Features

• instances: configure the IPv6 ExternalIP through a Node annotation (8d6cdd8)

Bug Fixes

• instances: skip IPv6 ExternalIP for Robot servers without a subnet (fix(instances): skip IPv6 ExternalIP for Robot servers without a subnet #1337) (3ec2945)

### IPv6 ExternalIP

We derive the IPv6 ExternalIP of a Node from the IPv6 subnet the server reports, by using the first address of that subnet. This is wrong for servers that use a different address out of their subnet, and Robot does not report a subnet for every server, in which case the Node got no IPv6 ExternalIP at all. You can now set the address explicitly through the Node annotation `instance.hetzner.cloud/external-ipv6`:

```bash
kubectl annotate node $NODE_NAME --overwrite \
  instance.hetzner.cloud/external-ipv6=2001:db8:1234::5
```

The annotation works for Cloud and Robot servers and takes precedence over the derived address. It requires IPv6 to be enabled for Node addresses via `HCLOUD_INSTANCES_ADDRESS_FAMILY`.
