Portability is the key for me, because I tend to switch things around a lot. Containers generally isolate the persistent data from the runtime really well.

Docker is not the only, or even the best way IMO to run containers. If I was providing services for customers, I would definetly build most container images daily in some automated way. Well, I do it already for quite a few.

The mess is only a mess if you don’t really understand what you’re doing, same goes for traditional services.

Most likely, a Hetzner storage box is going to be so slow you will regret it. I would just bite the bullet and upgrade the storage on Contabo.

Storage in the cloud is expensive, there’s just no way around it.

There was a good blog post about the real cost of storage, but I can’t find it now.

The gist was that to store 1TB of data somewhat reliably, you probably need at least:

• mirrored main storage 2TB
• frequent/local backup space, also at least mirrored disks 2TB + more if using a versioned backup system
• remote / cold storage backup space about the same as the frequent backups

Which amounts to something like 6TB of disk for 1TB of actual data. In real life you’d probably use some other level of RAID, at least for larger amounts so it’s perhaps not as harsh, and compression can reduce the required backup space too.

I have around 130G of data in Nextcloud, and the off-site borg repo for it is about 180G. Then there’s local backups on a mirrored HDD, with the ZFS snapshots that are not yet pruned that’s maybe 200G of raw disk space. So 130G becomes 510G in my setup.

They could explain things better, you are right. I actually think I remember having almost the exact same confusion a few years back when I started. I still have two keys stored in my pw manager, no idea what the other one is for…

The decryption has gotten much more reliable in the past year or two, I also try out new clients a lot and have had no issues in a long time. Perhaps you could give it a new go, with the info that you use the same key for all sessions.

I have a feeling you are overthinking the Matrix key system.

• create account
• create password you store somewhere safe
• copy the key and store somewhere safe
• when signing on a new device, copy-paste the key

Basically it’s just another password, just one you probably can’t remember.

Most of the client apps support verifying a new session by scanning a QR code or by comparing emoji. The UX of these could be better (I can never find the emoji option on Element, but it’s there…). So if you have your phone signed in, just verify the sessions with that. And it’s not like most people sign in on new devices all the time.

I’d give Matrix a new look if I were you.

Wireguard runs over UDP, the port is undistinguishable from closed ports for most common port scanning bots. Changing the port will obfuscate the traffic a bit. Even if someone manages to guess the port, they’ll still need to use the right key, otherwise the response is like from a wrong port - no response. Your ISP can still see that it’s Wireguard traffic if they happen to be looking, but can’t decipher the contents.

I would drop containers from the equation and just run Wireguard on the host. When issues arise, you’ll have a hard time identifying the problem when container networking is in the mix.

I used to run everything with Pis, but then got a x86 USFF to improve Nextcloud performance.

With the energy price madness last year in Europe, I moved most things to cloud VPSs.

One Pi is still running Home Assistant, hooked to my heating/ventilation unit via RS485/modbus.

I had a ZFS backup server with 2 HDDs hooked up over USB to a Pi 8GB. That is just way too unreliable for anything serious, I think I now have a lot of corrupted files in the backups. Looking into getting some Synology unit for that.

For anything serious that requires file storage, I’d steer clear from USB or SD cards. After getting used to SATA performance, it’s hard to go back anyways. I’d really like to use the Pis, but family photo backups turning gray due to bitflips is unacceptable.

They are a great entrypoint to self-hosting and the Linux world though!

Perhaps I misunderstand the words “overlapping” and “hot-swappable” in this case, I’m not a native english speaker. To my knowledge they’re not the same thing.

In my opinion wanting to run an extra service as root to be able to e.g. serve a webapp on an unprivileged port is just strange. But I’ve been using Podman for quite some time. Using Docker after Podman is a real pain, I’ll give you that.

on surface they may look like they are overlapping solutions to the untrained eye.

You’ll need to elaborate on this, since AFAIK Podman is literally meant as a replacement for Docker. My untrained eye can’t see what your trained eye can see under the surface.

In my limited experience, when Podman seems more complicated than Docker, it’s because the Docker daemon runs as root and can by default do stuff Podman can’t without explicitly giving it permission to do so.

99% of the stuff self-hosters run on regular rootful Docker can run with no issues using rootless Podman.

Rootless Docker is an option, but my understanding is most people don’t bother with it. Whereas with Podman it’s the default.

Docker is good, Podman is good. It’s like comparing distros, different tools for roughly the same job.

Pods are a really powerful feature though.

Even though you said “isn’t Nextcloud”, I’d still say it’s perhaps the simplest solution.

You can disable most the other apps and set calendar as the landing page. If you don’t use the other features, the resource usage is very low, just a cron job that does basically nothing. I don’t think disabling the default apps has much effect on the footprint, by the way.

Calendar, contacts and notes are why I still self host nextcloud. Just remember to pay/donate to Davx5, they’re one of the projects that need to keep running!

In Finland synchronization in gearboxes is starting to become a thing nowadays. Double clutching for 20 years now (38).

Just kidding, got my first automatic two years ago, so yes.

This must be related to people in their 20’s not knowing how to read a traditional clock anymore.

I’d go the SSH + sudo way.

Sudo can be quite finely tuned to only allow specific commands. If you want to lock the SSH session further, look into rbash.

Plain NGINX has served me well.

+1 for rootless Podman. Kubernetes YAMLs to define pods, which are started/controlled by systemd. SELinux for added security.

Also +1 for not using auto updates. Using the latest tag has bit me more times I can count, now I only use it for testing new stuff. All the important services have at least the major version as tag.

Rent a cheap VPS, ask your friends to gobble up the 1-2 units of local currency per month. Run a DNS over HTTPS server on the VPS (Adguard Home can do it, I’m not sure about PiHole), then just use browsers that can use a custom DoH resolver.

Don’t open port 53 to the public, that’s just asking for trouble. The bonus with this is the adblocking is in use on the go as well, and you can use the same server yourself.

Couple things that I’ve found out,

• Gmail seems to need your server to have IPv6 with PTR, even if the mail is sent over IPv4
• Even a DMARC record with no ruf or rua helps lower the spam score
• For Outlook you need to send some mail to yourself or someone else and mark the messages as not spam manually for a while
• MS365 will even put mails from Gmail to spam initially
• Some TLDs like .xyz will go to spam even if everything is set up perfectly
• Outlook also seems to cache DNS quite long, you may need to wait a day for changes to propagate
• A recently registered domain will land in spam more easily, if it has been registered for a while it also seems to help

If you’re not already familiar with these, https://mxtoolbox.com/SuperTool.aspx (write smtp:your.mx.record is a good tool, and I’ve also used https://www.mail-tester.com/. Mxtoolbox blacklist check is also good.

I hate it that spammers have made hosting email such a hassle. Hope you get stuff running!

The set up isn’t actually hard at all, if you understand the concepts. Keeping off blacklists is the hard part, as big providers often block entire IP ranges due to one bad actor.

Edit: I meant sometimes your server gets blacklisted for something some neighboring server did

No need to apologize.

You’d create a CNAME for myservice.mydomain.com, that points to proxynearorigin.cloudflare.com.

proxynearorigin.cloudflare.com contains the A and AAAA records for the reverse proxy servers. When you do a DNS query for myservice.mydomain.com, it will (eventually) resolve to the CF proxy IPs.

The CF proxies see from the traffic that you originally requested myservice.mydomain.com and serve your content based on that. This still requires you to tell Cloudflare where the origin server is so the reverse proxies can connect to it.

On the free service instead of the CNAME you set the origin server’s IP as the A and/or AAAA record. Enabling the proxy service actually changes this so that when someone makes a DNS query to myservice.mydomain.com they get the proxy addresses straight as A and AAAA records, leaving the IP you originally configured known only to Cloudflare internally.

It’s hard to explain this, and since I don’t work at Cloudflare the details may be off too. The best way to get an idea is play around with something like NGINX and run a local DNS server (Bind, Unbound, dnsmasq, PiHole…) and see for yourself how the DNS system works.

CDN isn’t really related to DNS at all. In the case of the CF free tier, it’s actually more like caching static content, which is technically a bit different. A CDN is a service that replicates said static content to multiple locations on high-performant servers, allowing the content to always be served from close to to the client. Where DNS comes in is that Anycast is probably used, and cdn.cloudflare.com actually resolves to different IPs depending on where the DNS query is made from.

There’s also the chance that I don’t actually know what I’m talking about, but luckily someone will most likely correct me if that’s the case. :)
