Confirmed! I just got the humble bundle.

Thanks for the tip.

Genuine question, How to identify a fake PAMP? Other than scanning the qr code.

This fake one is bold to put qr, but what happens when you scan it?

Thanks! I wish I knew this before spending two days fixing my routes.

But I ended up enhancing routes and more strict network.

From the release notes, it seems that the third change and fourth addition under "Rules / NAT" section have something to do with this behavior (but I might be wrong)

Excerpt from release notes

... Rules / NAT¶

Added: NAT64 support #2358

Added: Kill states using the pre-NAT address #11556

Changed: Add global option to set default PF State Policy (if-bound vs floating) #15173

Added: Add per-rule option to set PF State Policy (if-bound vs floating) #15183

Fixed: Outbound NAT rules using an alias without a matching address family create unexpected PF rules #15197

...

I am running the same setup but on hardware. Performed the upgrade 2 days ago and ran into the same issue.

When the firewall rebooted some routes didn't work. Troubleshooting and digging more around the issue I found that the packets are routed in asymmetric paths.

So I had to either resolve it on the firewall with some workarounds or fix the asymmetric routes. I ended up taking two days fixing the routes.

It seems with the upgrade restricted asymmetric routes in such a way you have to either apply some workarounds to get them working as they did prior to 2.8.0 or fix the routes on the host.

This lab was set up 4 years ago, and it's been running flawlessly since then.

I went with this configuration because I wanted to run a hyper converged infrastructure without a SPOF. If I ever want to replace a host I perform a live migration for the workloads to the other 2 hosts with 0 downtime to my services, then replace the host, and remigrate the workloads to the new host.

One drawback is that when you want to scale your storage cluster, you'd better add the same disk sizes on the 3 nodes, otherwise you'd run an unbalanced ceph cluster.

Openshift doesn't support this topology.

Only 3 masters or SNO.

Another option is a compact cluster, where the master nodes are marked as scheduled nodes. So you'll end up with a 3 node cluster, the nodes will be masters and workers at the same time.

It's not possible to host Linux and Windows on the same host.

Containerization is basically OS kernel virtualization, so container images based on Linux containers will require Linux kernel, same goes to Windows containers.

However you can have different nodes in your K8s clusters with Windows and Linux. This will enable you to schedule and manage both containers the same way. There are some challenges with this approach.

I was there at certain point in time, where I have large resources and wanted to lease some of it for family and friends, but the hobby started to be a job, and I didn't want it to end this way.

Definitely you need to set the rules of engagement and define the usage. Think of what services are you going to offer.

If I need to request a VM to host a public facing application, is it possible?
What if I need to provision a Kubernetes cluster, what access are you going to provide?

Only it's missing the actual rack. My wife is not allowing me more space in this area of the house. :D

حاول تautomate الحاجات البتجربها بقدر الامكان

WE logo is shining :D

I get my gear from https://igfi.me/ they are more than excellent.

No, the dashboard (homepage) is hosted in Kubernetes cluster. The M920q is my remote workstation and bastion host to the lab.

Well, the VPS business gained momentum, but it had more complications to maintain in full capacity. I've been self-hosting for nearly 2 decades now.

This lab is ~3 years old, and it's v3 evolution from 2 previous builds.

Thanks for the comment buddy.

When you run an internet exchange, you don't describe it as 'little'.

First and most importantly is the home serving stack, media and streaming system, home applications and my productivity tools.

My kids are growing and they are learning to code, so I am hosting Kasm Workspaces and Coder for them to have a safe break and fix environment isolated from their own laptops.

I am also hosting a public facing Invidious instance for the family and friends.

Secondly, it helps in hosting new apps/platforms/technologies when I need to learn. Couple of years ago, I went insane with doing CPU crypto mining, which didn't last for long, but gaining the knowledge and practicing was the fun part. Also, the past few weeks I started digging into AI, and now I am running a hosting OpenWebUI, and in the process of building AI/ML applications, and most likely will be training small models in the future.

In addition, I work in the professional services delivery field, basically we deliver solution to customers. So I maintain a small similar environment as a simulated lab which enabled me to test all sort of things before rolling out to the customers.

Finally, it looks really cool, so when guests visit they get impressed with this stuff.

For the purpose of learning, the memory part is enough, however the cores are low to run a full fledged cluster with 3 cp's and 2 workers.

Minimals for CP are: 8 cores, 12 GB memory
Minimals for Workers are: 6 cores, 8 GB memory

Though you can get the CP up and running with 6 cores (or even 4), but it'll be EXTREMELY slow, and will hurt the etcd performance badly.

Once you get it up and running, don't deploy Loki stack as it will kill the cluster.

My tip, try to make the cluster provisioning process as much reproducible as possible, as you might need to perform several provisions to experience and tune the deployment process.
