Those who are hosting on bare metal: What is stopping you from using Containers or VM's? What are you self hosting?

  I started hosting stuff before containers were common, so I got used to doing it the old fashioned way and making sure everything played nice with each other.

  Beyond that, it’s mostly that I’m not very used to containers.

  I’m doing this on a couple of machines. Only running NFS, Plex (looking at a Jellyfin migration soon), Home Assistant, LibreNMS and some really small other stuff. Not using VMs or LXC due to low-end hardware (pi and older tiny pc). Not using containers due to lack of experience with it and a little discomfort with the central daemon model of Docker, running containers built by people I don’t know.

  The migration path I’m working on for myself is changing to Podman quadlets for rootless, more isolation between containers, and the benefits of management and updates via Systemd. So far my testing for that migration has been slow due to other projects. I’ll probably get it rolling on Debian 13 soon.

  For me it’s lack of understanding usually. I haven’t sat down and really learned what docker is/does. And when I tried to use it once I ended up with errors (thankfully they all seemed contained by the docker) but I just haven’t gotten around to looking more into than seeing suggestions to install say Pihole in it. Pretty sure I installed Pihole outside of one. Jellyfin outside, copyparty outside, and I something else im forgetting at the moment.

  I was thinking of installing a chat app in one, but I put off that project because I got busy at work and it’s not something I normally use.

  I guess I just haven’t been forced to see the upsides yet. But am always wanting to learn

    containerisation is to applications as virtual machines are to hardware.

    VMs share the same CPU, memory, and storage on the same host.
    Containers share the same binaries in an OS.

      When you say binaries do you mean locally stored directories kind of like what Lutris or Steam would do for a Windows game. (Create a false c:\ )

  TrueNAS is on bare metal has I have a dedicated NAS machine that’s not doing everything else and also is not recommended to virtualize. Not sure if that counts.

  Same for the firewall (opnsense) since it is it’s own machine.

    Have you tried running containers on Truenas?

    • tofu@lemmy.nocturnal.garden ⁨5⁩ ⁨months⁩ ago

      No because I run my containers elsewhere, not on the NAS

  my two bare metal servers are the file server and music server. I have other services in a pi cluster.

  file server because I can’t think of why I would need to use a container.

  the music software is proprietary and requires additional complications to get it to work properly…or at all, in a container. it also does not like sharing resources and is CPU heavy when playing to multiple sources.

  if either of these machines die, a temporary replacement can be sourced very easily(e.g. the back of my server closet) and recreated from backups while I purchase new or fix/rebuild the broken one.

  IMO the only reliable method for containers is a cluster because if you’re running several containers on a device and it fails you’ve lost several services.

    Cool, care to share more specifics on your Pi Cluster

      I followed one of the many guides for installing proxmox on Rpis. 3node, 4gb rpi4s

      I use the cluster for lighter services like Trilium, FreshRss, secondary DNS, a jumpbox… and something else I forget. I’m going to try immich and see how it performs.

      my recent goto for cheap($200-300) servers are Debian + old Intel Macbook pros. I have two Minecraft bedrock servers on MBPs… one an i5, the other an i7.

      I also use a Lenovo laptop to host some industrial control software for work.

  I use Raspberry Pi 4 with 16GB SD-card. I simply don’t have enough memory and CPU power for 15 separate database containers for every service witch I want to use.

    Databases on sd cards are a nightmare for sd card lifetimes. I would really recommend getting at least a USD SSD stick instead if you want to keep it compact.

    Your SD card will die suddenly someday in the near future otherwise.

      Thank you for your advice. I do use a external hard drive for my data.

  • kiol@lemmy.world ⁨5⁩ ⁨months⁩ ago

    So, are you running 15 services on the Pi 4 without containers?

    source

    • kutsyk_alexander@lemmy.world ⁨5⁩ ⁨months⁩ ago

      The list of what I run on my RPi:

      • pi.alert
      • fail2ban
      • vftpd
      • samba
      • NFS
      • nextcloud
      • syncthing
      • squid proxy cache
      • PiVPN
      • pi-hole
      • gitea
      • classquiz
      • ntfy
      • redis
      • motioneye
      • vaultwarden

      Some of them runs in containers, some of them runs on bare metal.

  Are you concerned about your self-hosted bare metal machine being a single point of failure? Or, are you concerned it will be difficult to reproduce?

    Considering I have a full backup, all services are Arch packages and all important data is on its own drive, I’m not concerned about anything
