Re: Kubernetes Home – what do you do if your ISP changes your IP addresses?
#2Dealing with changing residential ips is nothing new. It's interesting to see how it's still being solved for even in this overly complex k8s landscape we find ourselves in now.
Back in the day we'd use free services like https://freedns.afraid.org/ on a cron to refresh the ip every so often.
I used afraid to refresh my dial up ip address, for my "hosting service" domain. The "hosting service" was an old tower pc living in the cabinet underneath a fish tank. Ops was a lot different back then...
Nowadays, if you're poking holes in your firewall and exposing your ip address to the world, you're doing it wrong. We've moved away from that model. There's no need to do that and expose yourself in those ways, when you can instead tunnel out. Cloudflare/argo tunnels, or tailscale tunnels, dial out from your service and don't expose your system directly to the open internet. Clourflare will even automagically set the dns for your domain to always route through that tunnel. Your isp allocated ip address is irrelevant, and nothing ever needs it because nothing ever routes to it. Your domain routes to a cf endpoint, and your system tunnels out to it, meeting in the middle. No open ports, no firewall rules, no NAT bs. Only downside is, you're relying on and trusting services like cf and tailscale.

Yeah, afraid.org used to work great. I mean the service still works great but Google appears to blacklist any domain with the nameserver there, all email goes to spam. I just found this out in the past month. Kept all my records the same and just moved the nameserver to Fastmail and the problem resolved immediately.
I have an unusual dynamic ip situation I've been taking advantage of with a different system. Some years back I noticed T-Mobile phone lines allow inbound connections on ipv6 (T-Mobile Home Internet unfortunately does not). I have a small weather station I run on a rpi3b I can access anywhere by using ddclient on the pi with cloudflare api key and it sets the AAAA record which is proxied by cloudflare, I leave the A record blank. If any users on ipv4 try to visit the site, cloudflare proxies it for them, works pretty reliably.

HELL YEAH. This is exactly how ipv6 is meant to be implemented. They deserve some real praise and recognition for this.

Why did they make it so inconvenient?

#6Crazy that someone is using something as complex as k8s on a home server and without knowing basics.
Newbies are better served starting with the simple stuff and then moving to the complex if needed

Home Internet is seemingly far more affordable than their phone plans. So they have other ways of encouraging you to use the phone plans.

#9How about a wireguard tunnel from an ingress box? You still pay for one VPS, but can run everything locally and just load balance at the ingress. I just manually add configs to nginx, but there are automated tools too.

#10> what do you do if your ISP changes your IP addresses?
I update the DNS record. Manually. It's a once in a blue moon thing, and I assume the probability of it is low enough that it will not occur when I'm so far from home that "it can wait until I get home" doesn't suffice.
15+ years or so now, and that strategy has worked just fine.
… TFA's intro could do with explaining why the IP is so hard coded in the cluster, or in the router? My home router just does normal port-forwarding to my home cluster. My cluster … doesn't need to know its own IP? It just uses normal Ingress objects. (And ingress-nginx.) I'm wondering if this is partly complexity introduced by having a |cluster| > 1, and I'm just on duck tales here. Y'all have multiple non-mobile machines? (I have a desktop & a laptop. I'm not running k8s on the laptop… because it's a laptop. I … suppose I could … and deal with connectivity to the desktop with like Wireguard or something but … why?)
My previous ISP offered static IP addresses, and I had one, since I had a somewhat special offer where the price wasn't terrible. It changed on me one day. They refused to fix that. I was very disappointed.
