Dealing 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 liv…

"Exposing your IP address to the world" seems like such an arbitrary thing to care about when you're opening a tunnel with the express intention of letting people in. No NAT bs, but you've got magic tunnel bs instead that you have no control over. And of course you're still "exposed to the world". Your IP address is public. That's the whole point. So you're going to be using a firewall regardless, what difference does one rule make really?

Crazy 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

Well, we've all got to start somewhere, right?

But yeah, I'd personally recommend Docker for self-hosting. Kubernetes or Proxmox always end up being too much to handle for personal use - or even small to medium sized companies.

My experience is this is no longer a problem. Ever since the US gov legalized data mining/spying/tracking I have not had my residential IP change. I think its more profitable to spy by essentially giving "free" static IPs to all customers.

Docker is kernel virtualisation. Are you thinking of OS virtualisation, like a VM?

Docker does not virtualize the kernel, in fact the kernel version “inside” Docker is the same as the host.

Wow, and I thought Comcast was customer hostile, this is just bonkers.

German ISPs are kinda weird like that. Unmetered gigabit FTTH for $70/month, no CGNAT, and open peering. 3 phone numbers and 2 phone lines included. But static IP isn't even an option.

I've built custom dyndns scripts to automate everything away, so nowadays it's only a second of interruption (thanks to some DNS TTL trickery), but it's nonetheless really annoying to deal with.

Tunneling through a single external node defeats the purpose of hosting k8s in home server. Maybe the external ingress node can be a load balancer controlled by the k8 cluster. But then you still have to communicate with the home server and it has no exposed ip address

It's caused (magnified by upstream requirements by the RIR due to ipv4 exhaustion and possibly reputation mgmt.

In order to get a block isps need to provide a plan on how they will put the ips to good use for the benefit of society.

I've been running a 2-node Proxmox cluster for about 3 years with close to no maintenance. What's too much about it?

It gives me easy VM and LXC management and very easy declarative networking and firewalling. That alone makes it worth it for me.

And having a single IP address, with one ISP at home isn't a SPOF?
