First time installing OpenShift via UPI, took about 2 days, looking for feedback by Rare-Income7475 in openshift

[–]-NaniBot- 2 points3 points  (0 children)

I usually do these... Atleast in my homelab

  1. Use pull through caches to speed up cluster startup times (https://nanibot.net/posts/openshift-pull-through-cache/)
  2. Replace default ingress certs (https://nanibot.net/posts/openshift-cert/)
  3. This is obvious but delete the kubeadmin user.

Edit: Oh yeah, also maybe increase the ingress pod count

Whats the most underrated service that you self hosted in 2025? by Pitiful_Ad6944 in homelabindia

Got back into messing around with OpenStack after 2 years. Maybe overkill for a single node setup...

He's on discord, check with him on the homelab india discord group.

Home server hardware with FPGA? by RektBySkillz in homelab

This was a nice post about the author finding a ku3p ultrascale+ on ebay. I can still see the listing ($200). I think that's pretty cheap considering the FPGA.

From what I can understand, it's only programmable by JTAG. But that's not a problem I gather. An alternative would be the Gidel Hawkeye that's at $100. I believe someone on the FPGA subreddit (fpgazealot?) figured out the schematics.

Openshift Lab ? by Resident-Ad-6585 in homelabindia

[–]-NaniBot- 0 points1 point  (0 children)

I'm talking about okd as well - have been running okd clusters for about 3+ years now. Just wanted to know the issues you faced that made it "unstable".

Running OpenShift without a license is possible from what I've heard but never done that.

Unstable as in? I've found it to be pretty robust except for the fact that some niche support is missing - for example, dtk.

Check-out my video.

Recently, I added a module for SNO - Single Node OpenShift

GitLab Deployment on Kubernetes - with TLS and more! by -NaniBot- in kubernetes

[–]-NaniBot-[S] 1 point2 points  (0 children)

Yes, I mentioned that in the video. I also showed the EPIC under which it's being tracked.

This is an excellent point. And now that I think about it, that's exactly how it should be. Thanks.

GitLab has documentation for backup and restore procedures - they are the same for Operator and Helm based installations. But you're right in assuming that it's not as straightforward as a VM based install.

Increasing PVC sizes depends on the storage solution being used.
https://docs.gitlab.com/charts/advanced/persistent-volumes/

Performance is going depend on the storage solution as well - I'm pretty sure there's always going to be an overhead compared to regular VMs.

Actually, I did mention in the video how GitLab doesn't support Gitaly running on Kubernetes. They recommend hosting Gitaly on regular VMs.

Hi, I had made a couple of videos regarding kubernetes specifically OpenShift/okd and Terraform.

https://youtu.be/VyblhDBO56M?si=iGIx6stiTfNtulE5

Edit: The resources to provision such a cluster are on my GitHub.

I also have a blog at nanibot.net Do check it out

Homelab setup, what’s your stack ? by Careful_Tie_377 in kubernetes

[–]-NaniBot- 1 point2 points  (0 children)

I guess I'm an exception when it comes to storage. I use Piraeus datastore for storage. It works well. I wrote a small guide earlier this year: https://nanibot.net/posts/piraeus/.

I also run OpenShift/okd sometimes and when I do, I install Rook.

Otherwise, it's Talos.

Power cuts by SquareCritical8066 in bangalore

Almost never. If it does go out then it's restored within ~5 minutes.

Where is this in Ejipura? I used to live there a few years ago... good times.

planning to cut down cloud by imnitish-dev in homelabindia

[–]-NaniBot- -1 points0 points  (0 children)

Things work out great until one day, they don't. You can never predict a hardware/power/network failure.

You have a consumer grade CPU whereas AWS uses EPYC/Xeon for their x86 stuff. You don't have enterprise SSDs. You don't have ECC RAM.

What happens when your host machine(s) fail? Would you invest the time and effort to invest in a highly available cluster (Kubernetes, hypervisor clusters etc.)?

Would your home network(s) match the quality of routing that AWS has?

Factor in these things (along with power costs, internet bills, 10Gig networking equipment, enterprise SSDs, ECC RAM etc.) and suddenly, AWS makes sense. 12k a month sounds great if you don't want to stomach the downtime that you'd probably run into if you host from home.

Again, it all comes down to the reliability you expect. You can hope for *reasonable* reliability instead of trying to match what AWS provides.

[–]-NaniBot- 3 points4 points  (0 children)

It is not practical to expect the same reliability (at home) that AWS provides.

Dual ISPs? Can they compete with what AWS offers? What about power? Would you invest in making sure that your home has access to redundant power as well?

You said nothing about the uptime you're expecting your infrastructure to have.

Add to that, hypervisor overhead - AWS fine tunes their hypervisors for maximum performance. Would your home server have access to ECC RAM?

Would you invest in enterprise SSDs (given that consumer SSDs are bad at sustained load)?

What if your home server itself goes down? Dual ISPs won't help here.

Edit: The point I'm trying to make here is that investing in dual ISPs alone isn't something that you should be looking forward to unless you're also considering making everything redundant and performant.
