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.

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.

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!

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.
