Is there limitations to installing Nextcloud via CT template on Proxmox

I have installed a Nextcloud on a container on Proxmox using the template on the printscreen, my question is if there’s any limitations by installing it this way, beacause i’m gonna use automated scripts on other networks, i already have a DNS pointing to its IP working and i’m planning on using WebDAV for this

While Proxmox does offer a CT template for Nextcloud, it’s difficult to evaluate how well it fits a user’s long-term needs without knowing the specific use case. On the surface, the CT template may seem like a quick and convenient way to deploy Nextcloud, but in reality, it introduces several limitations and hidden pitfalls that are important to consider.

:warning: What are the potential drawbacks of using a Proxmox CT template for Nextcloud?

  • Limited control over software versions:
    Most CT templates come with a pre-installed stack (e.g. Apache, PHP, MariaDB), which might include outdated versions of PHP or Nextcloud itself. This can make future upgrades more difficult or even unsupported without complex manual work.

  • Pre-configured setups may not match your needs:
    Templates are created with generic settings that may not align with your use case. If you need additional PHP modules, a different web server, custom security settings, or database tuning, it can be complicated to adjust the container environment.

  • Unclear update responsibility:
    When using a CT template, it’s not always obvious how updates should be handled. Should you update Nextcloud manually? Is the template itself maintained regularly? Users may find themselves stuck between trying to upgrade parts of the stack while fearing that doing so could break the template’s internal logic.

  • File system and permission issues:
    Since LXC containers use the host’s kernel, certain features like advanced file system permissions, NFS/CIFS mounts, and FUSE-based file systems may behave differently or be restricted altogether.

  • Troubleshooting limitations:
    Compared to full VMs, LXC containers can complicate debugging, especially when system-level packages need to be changed or reconfigured. Some logs and tools behave differently or are simply not available.

  • Security boundaries:
    Especially in unprivileged containers, you might encounter limitations with external integrations like Collabora Online, Full Text Search (Elasticsearch), or HPB (High-Performance Backend for Talk), due to missing system capabilities or AppArmor restrictions.

:white_check_mark: Why I prefer a VM with Ubuntu Server 24.04 + Nextcloud AIO:

Based on my own experience, running Nextcloud All-in-One inside a dedicated VM gives you full control, flexibility, and peace of mind:

  • A VM behaves like a real server, so you avoid all container-related limitations.
  • The AIO package simplifies setup and maintenance while ensuring best practices and up-to-date components.
  • Ubuntu Server 24.04 is stable, well-documented, and works perfectly with the AIO Docker setup.
  • You gain flexibility to integrate advanced features like object storage, external authentication, video calls, and backup automation – all without compatibility issues.

To back this up, here are some actual problems users ran into when deploying Nextcloud in Proxmox LXC containers:

:jigsaw: Conclusion

Although the CT template might look tempting for a quick deployment, it comes with too many uncertainties when it comes to customizability, long-term maintenance, and advanced Nextcloud features. For serious usage, I strongly recommend going with a VM running Ubuntu Server 24.04 and installing Nextcloud AIO via Docker. This approach has been 100% reliable for me and offers full compatibility with everything Nextcloud supports.

This is completely off topic, but I would be intrested what AI tools you use to write your answers, and in particular how you prompt them.

I mean this in all seriousness because the answers you post seem, at least at first glance, to be more specific and individual than the ones I get when I just copy and paste a post into a ChatGPT prompt, especially the second part of the post where “you” describe why you prefer a VM running Ubuntu 24.04.

However, if you look more closely (especially at the first part) it could still be improved a lot, because there is little to no specific information about the Proxmox CT template in the list of arguments against it, and some of the bullet points could be called outright factually wrong if the title didn’t say “potential” :wink:

My replies are not automatically generated without context. Here’s how I approach them:

  • :brain: Hands-on experience
    I run both Nextcloud and Proxmox in real-world setups. I deal with actual issues and fine-tuning related to performance, security, and backups.

  • :card_index_dividers: Personal notes in Nextcloud Collectives
    I document everything important in Nextcloud Collectives. I have a structured set of notes covering topics like installation, containers, backups, and performance tweaks. I’ll include screenshots to show how I work with them.

  • :robot: AI as a tool for rewriting and formatting
    When posting, I take my own notes or experience and feed them into an AI (usually LocalAI or ChatGPT). I use it only to:

    • rephrase things for clarity and better flow,
    • structure the content depending on the context (e.g., forum vs. wiki),
    • optionally add small details that would otherwise require looking them up manually.

  • :jigsaw: Bottom line
    Everything is based on actual use cases. I don’t post raw AI outputs — the answers are always rooted in what I’ve done or tested myself. And if something’s only in the experimental stage, I clearly say so.

Thanks for the detailed reply. And yeah, you can definitely see that there’s more to your posts than just asking the AI a few questions and then posting the RAW output :slight_smile:

Also, after rereading the first part, I have to admit that it’s not as bad or wrong as I made it sound in my previous post, but compared to the second part of your post, it’s still pretty vague, and if I had to guess, the AI/you ratio in the first part is probably roughly the opposite of the second part of your post. :wink:

Anyway, a solid post, though maybe a bit long :+1:
