A tiny solution to a tiny problem

Why?

• In my homelab I host a bunch of services
• When I add a service ingress I need to set up a host override on my DNS server
• This is boring and I always forget to do it (and rarely remove old ones)
• I don't want to use something fancy like external-dns because well, this is internal

How it works:

1. Curl(k8s-api/ingresses) --> jq(extract "address=/host/LoadBalancerIP") --> dnsmasq.conf
2. Reload dnsmasq
3. Sleep and repeat

Now just point DNS server to bottledns and resolve your ingress hosts.

Requirements:

• Ingresses with LoadBalancer IPs
• Service account with ClusterRole that allows listing ingresses
