Selfhosting Sunday - What's up?

What's up, what's down and what are you not sure about?

Let us know what you set up lately, what kind of problems you currently think about or are running into, what new device you added to your homelab or what interesting service or article you found.

  • I added a cheap PCI 4 slot NVMe expansion card and a couple of SSDs for a new pool and then migrated all the database-heavy stuff over to it. Required some use of local ZFS send/receive which I didn't know was possible, but it has gone smooth so far. Very happy with it! It no longer sounds like my HDD pool is trying to escape from hell and some of the services are much snappier, especially Bitmagnet. I'd highly recommend it as an upgrade for anyone still running purely HDDs. I thought I could get away with it but ZFS speeds are no faster than single drives and the amount of stuff I had was hammering it non-stop.

    I also bought my own domain finally to escape the free-tier dynamic DNS woes and I can finally feel good about sharing links with other people. I slapped a file share container with disabled registrations on a sub domain. I put it all behind free tier Cloudflare to hide my server's IP, it took a little bit of learning what the different records are but so far much easier than I thought. Although I have yet to do the hardest part of setting up dynamic IP for my DNS records. I see a bunch of scripts floating around, but none seem that easy or well-maintained...

    Oh, and the PI I've had running Pi-Hole v5 for god knows how long with no maintenance couldn't run Tailscale, so I wiped the entire thing to start fresh and got it up and running with Pi-Hole v6, Tailscale, and Unbound. I like having these separated from my other services as they are more critical to have at all times and I have had 100% uptime with my Pi so far. Although I chose Dietpi for my OS on a whim because it looked interesting and am not sold on it. I like that it has easy software installs with sane defaults so I probably saved time overall, but the amount of time I spent debugging the weird choices Dietpi made for basic shit like networking options really threw me off.

  • I'm moving to Podman quadlets for self hosting infrastructure (Forgejo and Woodpecker CI) and Kubernetes for the actual services. I also still need to figure out were I'm going to do SSL terminations.

    Nextcloud will be moved to Nextcloud AIO

  • Recently been working on setting up forgejo to migrate away from GitHub. My open source stuff I’ve actually put onto codeberg and I’ve set up a handful of pull mirrors on my local instance for redundancy. This weekend I’ve been testing out woodpecker-ci for automating pushing files to s3 for some static websites for repos on codeberg as well as my forgejo instance. Today will tell if that is successful!

  • Oh, I've just been tinkering around with LangFlow specifically as a news aggregator.

    Then asking AI to go get me some news: https://i.imgur.com/ltZPBwC.png

    Still needs a little tinkering and as the final step, to send said news stories to my Telegram. I really have a blast with automation platforms like N8N, Flowise, Gotify, DopplerTask, & Kestra.

    Afterwards, I smoked a small bowl and worked on a couple songs I have in the works.

    HBU?

  • I've been testing out immutable distros, in this case openSUSE Aeon (laptop) and openSUSE MicroOS (server).

    I set up Forgejo and runners are working, all in podman. I'm about to take the plunge and convert everything on my NAS to podman, which is in preparation for installing MicroOS on it (upgrade from Leap).

    I also installed MicroOS on a VPS, which was a pain because my VPS provider doesn't have images for it, and I'd have to go through support to get it added. Instead, I found a workaround, which is pretty amazing that it works:

    1. Install Alpine Linux (in my case I needed to provision something else first and mount an ISO to install Alpine, which was annoying)
    2. Download MicroOS image on VPS (not ISO, qcow image)
    3. Write image to the disk, overwriting the current OS (qemu-img command IIRC)
    4. Reboot (first boot takes longer since it's expanding the disk and whatnot)

    The nice thing is that cloud-init works, so my keys set up in step 1 still work with the new OS. It's not the most convenient way to set things up, but it's about the same amount of time as asking them for an ISO.

    Anyway, now it's the relatively time consuming task of moving everything from my other VPS over, but I'll do it properly this time with podman containers. I had an ulterior motive here as well, I'm moving from x86 to ARM, which reduces cost somewhat and it can also function as a test bed of sorts for ARM versions of things I'm working on.

    So far I'm liking it, especially since it forces me to use containers for everything. We'll see in a month or two how I like maintaining it. It's supposed to be super low effort, since updates are installed in the background and applied on reboot.

  • Building a simple workflow with AI agent for our community watch group. Also building an open source automation platform, currently working through GUI templates for it.

  • I've just moved and I'm setting up my machines. NIC died in my DIY router just before the move so I'm upgrading to 2.5/10 Gbps at the same time.

    • What NIC are you looking at and what OS have you chosen?

      • It's a complete experiment with cheap network gear from China. I have a HP T730 mini PC that serves as my router. I'm installing a cheap 2.5 Gbps NIC for LAN side. Then there's a switch with 4x2.5 Gbps Ethernet and 2xSFP+ ports. My two main machines (PC and home server) are getting 10 Gbps SFP+ cards that I'll attach with DAC cables.

        OS is OpenWRT, because I've been connecting over WiFi to the Internet in both old and new locations. OPNsense just will not work with any wireless adapter I've tried. I will try agan once I route Ethernet to my room.

        I'm curious if all of this works with cheap network gear. Today I'm configuring a fresh OpenWRT installation on the router.
