notfromhere, in Teachings from years of HomeLab

I get what the author is talking about with losing trust in your services when they are unavailable. I have found that a Raspberry Pi 3/4 cluster running k3s utilizing NAS storage has very good uptime and honestly I think my internet service goes down more than my homelab services.

Thanks! I find most of the issues occur during upgrades to services, but that is to be expected.

My internet service is usually more of an issue than most services I run. Though some things take longer to get tweaked and running well and that can cause issues.

notfromhere,

Upgrades to services - that’s why I run dev namespaces and copy over my production shares to dev and utilize zfs snapshotting.

I haven’t set up testing yet and only just started with prometheus monitoring but so far things run pretty well.

Oh, dev namespaces are a good idea. Do you have a dev domain then too?

notfromhere, (edited )

I toyed with dev domain but ended up using namespace.tld and postfixing -dev to my namespace so it works out to service.tld and service-dev.tld.

@jax@lemmy.cloudhub.social avatar

Ah okay that makes sense, you’re using the internal cluster domain to route to services

notfromhere,

I have automated traefik to route the traffic, it sets the dns and ingress route. I’m also doing as you suggested for service to service connections.

jax,
@jax@lemmy.cloudhub.social avatar

That makes sense!

Have you played with anything like Istio to secure in-cluster communications? I think Hashicorp Consul can do something similar to encrypt service to service communications.

notfromhere,

I looked into it but I felt at the time it was too complex, maybe I’ll look at it again. Currently I am using wireguard for all cluster node-to-node traffic. It seemed like a reasonable tradeoff at the time, but it is at the network layer instead of application, so I really should revisit that at some point.

@jax@lemmy.cloudhub.social avatar

Yeah it very adds some extra complexity and it’s more important for if you are hosting in public clouds anyways IMO.

jax, in Internal SMTP relay?
@jax@lemmy.cloudhub.social avatar

I think I’m going to end up using docker-mailserver for this.

@jax@lemmy.cloudhub.social avatar

That seems really resource heavy. 4 Gb of RAM for an SMTP relay?

Other than that it looks pretty great.

Kritoke, in Best online VPS

Another vote for Hetzner Cloud, if you don’t mind it being in Germany, you can get even more memory and other specs on their ARM based ones. It does has pretty cheap backups and has DDoS protection and some basic firewall stuff built in all their VPSes.

marv99, in Lab rebuild next steps

Very nice and clean setup.

Unfortunately for that price you're completely dependant on thing being able to be sniped. Look into liquidation auctions, as they generally sell out of warranty really cheap servers.

Crinkly4516, in [Reposting] Server recommendation

r7 5700g, b450(bios updated) motherboard, 128gb you could probably get for ~£300.

ryknow, in Server recommendation

Is 3.5" drive bays a deal breaker? Cause if not, I absolutely LOVE my Hyve Zeus servers!

thomas, (edited )

Do you mean 2.5"? It probably is a deal breaker sadly, unless I can build a DIY SAN or something (I would love to). It sounds bad but I'm probably going to super cheap out on HDDs and buy those crappy £9 SAS drives from ebay and just use aggressive RAID and backups

Also, I can't find a single one of those that isn't shipped from the USA

ryknow,

No. I meant 3.5" your original post listed >= 4 3.5" bays.

In my hyve Zeus servers I run two ssd's in a mirror, and then host all my data on a trunas server with an nfs share. That said, ssd's are really reasonable (just bought 2 x 2packs of 1tb ssd's for $66 each). If space requirements exceed what you can do with some ssd's, then I get it.

I have an r510 as a trunas server. It uses well over a 100 watts, so I can at least provide you that info. Haha.

thomasdouwes,

Nuked my lemmy by accident so using a different account.

No. I meant 3.5" your original post listed >= 4 3.5" bays.

Sorry I figured that out after posting but couldn’t edit.

I was hoping to get about 18TB in RAID but really I should probably just built a dedicated NAS with some new drives not crappy used ones anyway. I found a listing for 3TB SAS HDDs for £9 each, probably really bad drives though.

I have an r510 as a trunas server. It uses well over a 100 watts, so I can at least provide you that info. Haha.

I’ll have to think about that. It’s cost more to run the server for a few months that to buy the thing if it uses too much power.

MigratingtoLemmy, in Wired up the rack, but you get what you pay for

That doesn't look too bad, but figuring out which cable goes to which appliance is a bit difficult. With that said, I don't see that many devices in your rack, what do you need that many cables for?

It's a pity no one is participating here. So many posts I see that are going unanswered. People really have let Reddit into their arsehole without appropriate rubber. Your rack is looking great, would love to know the plans for the future. I am personally going to stick with a MicroATX computer and a 6U standing rack, both on my table (when I get there, it's a long way off). Cheers!

I don't need that many cables! But I thought I'd wire up the entire switch and that was I could play with port configs by changing the patch cables.

greg, in Best online VPS

I'd recommend giving Hetzner a look, they're similar to Linode/Digital Ocean/etc., but they're a bit cheaper. They're a European company, but they've recently added a couple North American locations.

NotAnArdvark, in Best online VPS

Google Cloud has a free tier, as do many other large cloud providers (Oracle and AWS for sure).

Google Cloud is a little tricky because you just configure a Google Compute instance to match what they say is free, then cross your fingers you don't get billed (at least that's my experience).

MigratingtoLemmy, in Finally racked my lab

Hi, would love to know your opinion on your networking gear. Could you detail your pfsense build and how that switch is treating you? Thanks

lungdart,
@lungdart@lemmy.ca avatar

The tp link jetstream is decent. They're managed (with a proper ios like cli!) There's also access points that can tie into them nicely.

The PFSense build is 6 or 7 years old now. Its one of the supermicro embedded boards. Probably an x9. It has an ssd, 4 1gbe ports and 8gb of RAM. It can handle lots of rules, and lots of traffic!

lungdart, in btrfs + snapraid: good idea for homelab?
@lungdart@lemmy.ca avatar

I tinkered with the same idea when I built my Nas a few years back. Decided against it and went with raidz2.

Let me know if you go for it and it works!

Side note: I'll be updating my lab to rancher harvester W/ k8s this weekend, so I'll be using Longhorn for storage. Should be interesting!

caio, in [Guide] Getting Lemmy Working on Docker

Nice! I couldn't really get the docker setup going and am pretty busy with other things so just went with the ansible option. But when I have time I'll give this another try so I can host more services on the server since I'm familiar doing that on docker but had never used (or heard about!) ansible before :)

This is an awesome guide on how to install Lemmy on Docker!
