THIS is the future of homelab, excited to see someone who knows so much more about hardware than I do get excited about this.

oof, outage on the homelab during vacation, brutal. I can think of a couple of similar solutions to what @pype has done to tailscale in, but I’m not sure that I could do this remotely. On one hand I’m so glad that cloudflared just takes care of certs on the other hand this really brings a gap in my understanding of what the heck I would do if it were broken.

An untested DR plan is not a DR plan.

An untested backup does not exist.

I learned to today that setting MEMORY on your minecraft server causes the JVM to egregiously allocate all of that memory. Not setting it causes slow downs and potential crashes, but setting INIT_MEMORY and MAX_MEMORY gives us the best of both worlds. It is allowed to use more, but does not gobble it all up on startup.

In this economy we need to save all the memory we can!

Here is a non-working snippet for a minecraft server deployment in kubernetes.

containers: - name: dungeon image: itzg/minecraft-server env: - name: EULA value: "true" - name: INIT_MEMORY value: "512M" - name: MAX_MEMORY value: "3G"

and in docker compose

Today I learned that while .stignore and .gitignore look very similar they are not. My obsidian directory had been locked up for a few weeks and I had no idea why until I logged into the web ui and saw errors. The errors were some confusing regex validator not matching. I don’t know what the exact error was, but I went in and only ignored the files I cared about instead of the entire gitignore. Primarily I was getting conflicts in my .git directory.

Today I learned how to use tar over ssh to save hours in file transfers. I keep all of my projects in ~/git (very creative I know, I’ve done it for years and haven’t changed). I just swapped out my main desktop from bazzite to hyprland, and wanted to get all of my projects back. Before killing my bazzite install I moved everything over (16GB of many small files), it took over 14 hours, maybe longer. I had started in the morning and just let it churn.

This was not going to happen for re-seeding all of my projects on my new system, I knew there had to be a better way, I looked at rsync, but for seeding I ran into this tar over ssh technique and it only took me 6m51s to pull all of my projects off of my remote server.

David’s got me looking at Forgejo. I’ve seen a lot of GitHub jumpers just this week, and I’ve been tempted for a long time to self host one anyways, so it might be time. I don’t have hard issues with anything, I just like self hosting my own personal stuff.

On the flipside, I hope this does not turn yet another thing to shit. I lived through the download software from sourceforge and hope you get the right download now button and not the one from the virus ad. I’m not putting my really public/useful projects on a self hosted platform… well not as the only source, I see how that comes off edgy. I like having some trust in the platform. Currently theres a lot of issues with M$ and GitHub using you for your data, but I don’t think injecting virus, malware, bitcoin miners is a worry I have coming from a GitHub release, unless it was put there by the author.

Great guide to setting up a samba server right in kubernetes. I tried it out after too long of playing with trying to get connected to a samba share on ucore, no idea what was wrong, but this just works, and will live in my homelab no matter what distro I’m on, no playbook required to set it up, just good ol k8s manifest. TBH I cheated and haven’t set up the secrets yet, so its not quite in argocd or in my github repo, but POC is there and it works as advertised without issue.

Always enjoy a good read through someone elses setup. I appreciate the desire for pi clusters they are cute, they seem cheap, but feel a bit overrated (at least for those of us with relatively cheap electricity). I love seeing the refurb “tiny desktops” getting a second useful life in a homelab after they have serve their useful life in the corporate world sitting behind the monitor of some reception desk. These things rock, they are underrated, x86_64, not ARM, so they just work. Until ARM becomes more normalized in the datacenter this is where its at.

I’m way behind on my notification game and need to pick it up. maybe I’ll look into hcio as well. maybe I’ll look into something that goes straight to signal or just get things working on ntfy. An 80GB log file is massive and the kind of thing id like to see notifications more.

I didn’t realize that postiz had a helm chart, I just hand rolled mine based on the compose file they provide. I went from running the compose stack locally to running in my homelab with kubernetes. I am using cnpg rather than a postgres container which I really like the workflow of as far as backup and restore. The one hiccup I ran into was changing the domain from localhost to my homelab domain killed all of my integrations and they needed the redirect url updated.

Interesting takes on Diun here. I agree that I like to be in control of updates and pinning not to latest. both seemed like they weren’t going to run it because they can look up the latest version. Maybe I need to be less aggressive on keeping things up to date and its a me problem. I just got diun setup and hooked into ntfy, and I kinda like the automated checklist of new images that I can review and update.

To be a bit more clear, having control over changes coming in from others, even if I dont care to see the changelog, it is nice to roll out an update, have it in your git history, watch it deploy and work like before, if not roll back and read the changelog. For internal applications I’m down for automated releases like argo image updater give you, this thing has already gone through review, launch the damn thing at least to a dev space.
