One thing to consider before doing the same, a computer done for homelab has a much lower consumption. The setup mentioned in the article has an avg 600 kWh/year as opposed to a pretty solid HP EliteDesk (my own homelab) which uses 100 kWh/year. Sure you don't get a GPU but for what it is used for, you might as well use a laptop for that.

I have chromebox (with 32GB DDR4) that idle at 4W, but after adding couple nvme drives it doubled it's power consumption. Having full ATX mobo is cool (flexibility), with BIOS settings, powertop, and some other settings can also idle at quite low power. I have i7-7700K that idle at 18W. With combination of wake-on-lan and similar you can have a monster but won't empty your wallet.

For anyone considering this, it's not a good plan to do it this way, if you have any family members relying on these services, you have to kill them all every time you reboot your workstation. It's really not great to mix destop and server like this. (speaking from experiance and I really need to get a separate box setup for this self hosted stuff)

You are always gonna have some downtime in a homelab setup I think. Unless you go all in with k8s I think the best you can do is "system reboots at 4AM, hopefully all the users are asleep". (Probably a lot of the services I run don't even really support HA properly in a k8s system with replicas. E.g. taking global exclusive DB locks for the lifetime of their process)

I run my stuff in a local k8s cluster and you are correct, most stuff runs as replica 1. DBs actually don't because CNPG and mariadb operator make HA setups very easy. That being said, the downtime is still lower than on a traditional server

In Bitwarden they allow you to configure the matching algorithm, and switching from the default to "starts with" is what I do when I find that it is matching the wrong entries. So for this case just make sure that the URL for the service includes the port number and switch all items t…

Just giving them hostnames is easier. In homelab space you can also make wildcard DNS pretty easily in dnsmasq, assuming you also "own" your router. If not, hosts file works well enough. There is also option of using mdns for same reason but more setup

Bitwarden annoyingly ignores subdomains by default. Enabling per-sudomain credential matching is a global toggle, which breaks autocomplete on other online service that allow you to login across multiple subdomains.

Folks that use restic - how does it handle laptop backups? That is - handling laptop going to sleep during backup, laptop being on only for shorter periods of time, etc.? Because I had issues with backup tooling which wouldn't resume if it got interrupted and expected for the machine to always run at certain hour of the day. I had examples where laptops wouldn't backup for months because they were only on for a short…

I invoke backups from a systemd timer. If the schedule is missed (due to sleep, power off etc.) it runs it at the next earliest opportunity.

How does it handle restart after the machine wakes up again?

I think most homelabbers default to Caddy and/or Traefik these days. Nginx is still around with projects like NPM (the other NPM), but Caddy and Traefik are far more capable. DevOpsToolbox did a great video on many of the reasons why Caddy is so great (including performance) [0]. I think the only downside with Caddy right now is still how plugins work. Beyond that, however it's either Caddy or Traefik depending on my…

far more capable is an exaggeration I use both, they are by and large substitutable. Nginx has a much larger knowledge base and ecosystem, the main reason I stick with it.

Just as one small example: if you're deploying in k8s and want the configuration external to Nginx, you want built in certificate provisioning and you need to run midleware that can easily be routed in-config...

Traefik is far more capable, for example. If all you're doing is serving pages, sure.

Tell me about it... that infinite Ctrl + Shift + L sequence circling through all credentials from all subdomains. Then you brain betrays you making you skip the right credential... ugh, now you'll circle the entire set again. Annoying.

I run (among many other VMs) TrueNAS on a VM of an xcp-ng host (Supermicro board with a Xeon and ECC ram). Passing a dedicated SAS controller to it. Before that I was using esxi but migrated all my VMs and hosts to xcp-ng. TrueNAS has been pretty good so far, been running this for many years already.

I also have another xcp-ng host for other VMs running on a Dell OptiPlex Micro.

OP should configure DNS locally and reverse proxy each service, I use bind 9 and nginx for that.

> Impressive that all that can run on one machine. Mind sharing the specs? Not GP but I have lots of fun running VMs and lots of containers on an old HP Z440 workstation from 2014 or so. This thing has 64 GB of ECC RAM and costs next to nothing (a bit more now with RAM that went up). Thing is: it doesn't need to be on 24/7. I only power it up when I first need it during the day. 14 cores Xeon for lots of fun. Only th…

Cheap to buy old hardware, but electricity to run those old rigs isn't really cheap in many areas now. My server is costing me about $100/month in electricity costs. It does have 16 spinning disks in it, so I accept that I pay for the energy to keep them spinning 24/7, but I like the redundancy of RAID10, and I have two 8-disk arrays in the machine. And a Ryzen-7 5700G, 10gbit NIC, 16 port RAID card, and 96GB of RAM.

I’ve been watching some storage and homelab-themed videos and I heard there’s a lot of optimizations you can do to lower power usage - spinning the disks down, turning the machine on for a limited time, etc.

You can override the matching method on an individual basis though, just using the setting button next to the URL entry field.
