A recent storm damaged the siding of my house so I'll have to have it replaced. The thought occurred to me to run some network cabling behind the new siding (and likely new insulation) while its all pulled off. Should I run standard riser cabling or outdoor-rated cabling if I do so?

Obviously the most ideal solution is standard in-wall but I don't have the appetite for such a project given half the house was built in the 19th century and I know such an undertaking would involve quite a few surprises that I almost definitely lack the know-how to handle, and I'll probably be moving in a couple of years so I don't want to invest too much time or money into the endeavor.

Alternatively is there a good type of conduit I could run instead?

I have tried to follow several tutorial to setup using either ip or nmtui:

• https://linuxconfig.org/how-to-use-bridged-networking-with-libvirt-and-kvm
• https://www.redhat.com/sysadmin/setup-network-bridge-VM

However, the bridge inherits the MAC address of host after enslaving the host hardware enp1s0.... This causes my router to give both the host and the bridge the same ip address, making the ha instance inaccessible.

The red hat tutorial clearly show that the bridge and the host have different IP, so I was wondering if I am doing something wrong.

Alternatively, I can set the home assistant vm to run in NAT and port forward from host, but I have several devices that communicate over different ports. So it would be annoying to forward all these ports. Not to mention, many appliances don't have documentation about the ports they use.

I can also potentially use virtualbox, but it is not well

Starting a new Cloud/HomeLab blog at this domain - let me know if you want a contributor invite!

I am running a Kubernetes cluster for this domain, and I'm looking at more services to run (right now I have Mastodon and Lemmy).

I was considering WriteFreely and PixelFed, but they don't seem to have an easy solution for running on Kubernetes (WriteFreely doesn't even have a production-ready docker image).

Is anyone else running federated services in their lab? Do you run any of them on Kubernetes?

Reposting some of my older popular blog posts. This one is probably out of date, I doubt the configuration examples still work as they did back in 2020.

I have a need for an internal SMTP relay inside a kubernetes cluster. What is everyone using for docker/kubernetes SMTP relays these days?

Goal is to have all internal services route emails through this relay and it in turn sends the emails out via SendGrid, should be a fairly easy task, just not something I've done for a few years.

Hey all! We're back after a couple of weeks of downtime on Lemmy due to some DB migration issues + Kubernetes liveness timeouts, and general lack of time to troubleshoot. For the latest status, you can view the status page for the cluster here: https://cloudhub-social.github.io/Status/

We are also well overdue for a What's in Your Homelab for the month of August, so we'll use this post for that as well!

Since it's been about a month since the last post, it's time for another one!

"What's in your homelab?" (July 2023)!

This could be anything from hardware to software to things your running in the cloud (#cloudlab).

Hardware and diagram pics are always welcome!

A rpi 4 running pihole and small scale backups through rsync, two HP elitedesks, one running ESXi 6.7, other running Ubuntu with multipass and docker, and a Dell SFF running unraid.

It ain't much, but it gives me some play areas and backup capabilities for the house.

A little update on the racking the basement lab.

New patch panel and cables made my life much easier. All the packets are flowing! Working out some KVM issues while I get rancher harvester deployed.

Oops! I just nuked my lemmy instance and the other post wasn't in by backups, sorry about that! please don't reply to the other post because I can't see it

Hello, I’m looking for a good first server for a homelab. I do already have an old Dell poweredge 1950 I got for £30 but it’s:

        Loud
    Draws 350W
    Costs too much to run
    Only has 2 HDD slots
    DRAC card needs Internet explorer


  

I’m not too bothered by the noise because I can just move it, but the electricity cost is quite ridiculous for something less powerful than my PC in every way. I live in the UK so electricity prices are a huge factor for this.

My Ideal specs are:

        ~16 cores (total)
    >= 128GB RAM
    ~100W idle power draw
    >= 4 3.5" HDD bays
    Preferably HBA mode on RAID card
    £100-200

Is this completely unreasonable? I have found servers that match this all except the 3.5" bays and 2U. Initially I found a Dell server with 128GB of RAM and two 12 core CPUs for about £200 but I

Rack is wired (patch cables ordered). Unfortunately the second hand patch panel is a bad idea, less than half the ports are functional...

I ordered a rj45 cat6 through panel and a bunch of premade cables. Should be here at the end of the month!

I'm looking to learn more by using a VPS and spinning up a few instances. Can anyone recommend a cheaper VPS service?

Please let me know if it would be better to post this in a different community. TYIA

Finally got around to racking up my lab! (Still needs wiring up, but that's tomorrows problem)

Top to bottom:

• 1u PDU
• 1u cable management
• 1u custom super micro pfsense build
• 1u tplink jetstream. 24x1Gbe 4x SFP
• 1u cable management
• 2u patch panel
• 4u custom super micro server
• A shelf with a UPS and a gaming rig (ryzen with a 1070ti)

Going to run rancher harvester + rancher vm + k8s cluster. Usual media stack, nextcloud, pihole, etc etc.

Mostly just want a cluster to play with and harvester seems fun!

Hi!

I'm about to upgrade my homelab from a RAID1 with two 8TB drives to a new one with two additional dives. I mostly use my homelab for Nextcloud (Documents, photos, audiobooks, ...), media storage, jellyfin and whatever docker container I think would be cool to self host.

Since data availability is less of an issue for me and Backup Space is limited, I'm thinking of ditching the RAID in favour of btrfs and for additional safety: use one of my 8TB drives as a Snapraid parity drive. At least for the personal nextcloud data - I can get the media files from elsewhere in case of data loss.

However, tutorials of btrfs with Snapraid are a bt thin on the ground and with this being my first time using btrfs, I'm a bit hesitant. Some people suggest MergerFS with btrfs + snapraid, but I fail to see the advantage of MergerFS with btrfs.

So... is this actually a good Idea? It seems to me that this would be a good tradeoff and I could wait a bit before the next time I need to buy a storage upg

What's everyone using for status monitoring and/or status pages either in their lab or at work?

I setup a status page for my fediverse instances using Uptime Robot (have an existing subscription), and the features are kinda lacking. I feel like they haven't really updated anything in the last 5 years which is unfortunate.

Boy howdy, there are a lot of people coming to the matrix chat trying to figure out how to get lemmy working on docker who are stuck on the official documentation. This document is my guide on how I got Lemmy working. I'll also share what I don't have working yet to inspire further.

Please feel free to steal anything you want from this and put it into the official docs. I don't know the contributing policy and it sounds hard and I'm busy at the moment.

Of note: I add a nginx container in this setup so that you don't have to do crazy hacks on your end for locations. If you already have an nginx reverse proxy that you are using, just use this one as a 2nd layer of nginx. There is low overhead, so don't worry about it.

For this guide, I'm requiring that you already have your own reverse proxy setup in place that

Figured we'd start this community off with a question about what you're running in your homelab!
