Cannot setup ingress-dns Ubuntu 22.04

[gpelouze]

On Ubuntu 22.04 we cannot setup minikube ingress-dns following the official instructions.

This is because Ubuntu 22.04 relies on systemd-resolved, while the documentation only supports resolvconf and NetworkManager.

• https://github.com/kubernetes/minikube/issues/10517
• https://github.com/kubernetes/minikube/pull/16575

These solutions involve bypassing systemd-resolved (too invasive), or manually editing /etc/resolv.conf (will be overwritten).

We can do the following:

sudo mkdir /etc/systemd/resolved.conf.d
sudo tee /etc/systemd/resolved.conf.d/minikube.conf << EOF
[Resolve]
DNS=$(minikube ip)
Domains=~test
EOF
sudo systemctl restart systemd-resolved
