    MergerFS setup for LXC

    Hello, I am planning a setup where I will likely be using MergerFS to create a pool of multiple drives for an LXC.

    [TUTORIAL] How to Make Fstrim Run More Often in LXC Containers and Linux VMs + the Host (for GRUB and Systemd Proxmox VE Installations)

    This is a tutorial on how to make fstrim run more often or on days that you wish. This could be handy if you have stuff continuously writing to the drives which then later gets deleted, which would cause it to create a large amount of unused data. For example, I have a Minecraft server running...

    How do I access the template I created?

    I've set up an Ansible script to build a very basic Debian 12 container. Unfortunately, apt dist-upgrade hangs for 10 minutes the first time it's run, so I want to create a template from the point where that command finally finishes (I need to apt dist-upgrade because the base image...

    Upgrading Containers to u24.04

    TLDR it failed to boot. Then I upgraded proxmox for some other reason and when it rebooted my upgraded container sprang into life. So the questions is - is this something to do with the kernel being upgraded? I'd just like to understand that a bit better. I had upgraded containers before and...

    Official source and updates for CT templates

    I've recently moved to Proxmox VE for my homelab, following our company and I have a number of LXC containers running. I also write the documentation for the setup of those. I'm now wondering where the official (as provided via "Templates" in the CT Templates on Proxmox) are hosted and how I...

    Introduce new mapping for each unprivileged container

    Hello, I'd like to set up a collection of unprivileged containers, each with access to a different ZFS dataset. Since the default mapping between host and container UID/GID is always the same, this seems to introduce a security risk. If a container is compromised, the attacker could access all...

    Feature request: pre-set SSH keys

    When creating container there is an option to enter root password or upload SSH public keys. That is very useful; what is inconvenient is that one needs to find their keys each time. What would be convenient if we had a way to set up "default" keys in advance in e.g. user profile, and then have...
