However, this is me talking out of my ass, and if anyone has real information Edit: I was on mobile before so let me give a bit more detail. Neither is acceptable to me. I'm migrating to a new Proxmox build with plans to run either TrueNAS or Unraid (since I already have the license purchased) virtualized with direct access to the hard drives STRICTLY for NAS/data storage (not running containers or apps) and running I have moved away from UnRAID to Proxmox since the last week due to the need of a better VM backend (had a lot of issues trying to run a gaming vm on it and unraid seems like: here's 50 tips to get a better gaming performance, while on proxmox it just works without any "copy this tweak" thing), now I'm in the process of moving all the stuff I had on docker over to Proxmox and I The Docker LXC has two volumes, the first is rootfs and the second is the mount point with all containers' data. LXC produces entire kernels inside the hyper visor kernel. From what I can tell, LXCs are lighter, faster, and easier than VMs, but can only run As in Proxmox you can create both virtual machines and Linux containers to host your chosen apps and services, you might be wondering what are the most important differences between the two, and which one is better The Proxmox hypervisor natively supports two types of virtualization: Proxmox CT or LXC (Linux Container) and KVM (Kernel-based Virtual Machine) VMs. That's why I have a Docker LXC and Docker VM right now. SSH Public Key: a public key for connecting to the root account over SSH Docker went after a different target market, developers, and sought to take containers beyond the OS level to the more granular world of the application itself.

In this article, we will dive into a comprehensive comparison of Proxmox and Docker, highlighting their strengths, use cases, and performance in order to help you make an A single host running a container service and a hypervisor (i. The first step in installing Docker on Proxmox is to set up LXC I have been reading a lot about how it is not recommended to use podman or docker in a lxc. After the 512mb mem it just depends on what application I have running in the VM. Docker is not supported directly. You can run “proxmox docker lxc” through your favorite search engine (not as a quoted phrase, of course). Docker/Podman produce reconstructable services inside the same kernel space so they’re very client-friendly. Proxmox also uses LXC, but not LXD, to make its containers. On the other hand, Portainer focuses on Docker container management and provides Now I would like to understand whether I should install HA in a VM as a docker container or install HA directly on a separate LXC without docker.

As a longtime Docker user who recently started using Proxmox, some thoughts: LXC via Proxmox is great for stateful deployments on baremetal servers. This forces you to either giving up Promox' built-in snapshot and migration features (the zvol +ext4 way) or risk crashing your PVE node now and then (the fuse-overlayfs way). In both VMware and Proxmox, their VM can also run docker or k3 containers. But if you have a few node, you could do a cluster of kubernetes, proxmox handles the networking very well. It just streamlines so much and avoids the layer of abstraction you will If you’re wondering if it’s better to run one VM with a few Docker containers running on it, or a few containers managed within Proxmox, in most cases it’s a simple question of which technology are you more comfortable working with, what is your particular use case, and whether or not you want to be able to easily manage (and monitor) your hosted services directly from IMO most people here are running homelabs for which this point is mostly irrelevant as the amount of work of moving your small docker stack manuall vs. (I am running Proxmox and run Docker in an LXC container. the CT ID: a unique number in this Proxmox VE installation used to identify your container .

Docker is better suited for rapid deployment and portability across various environments. moving your LXC manually is roughly similar, but I assure you, that in larger scale deployments, there is always a decision between Docker on bare metal for one less layer of complexity vs Docker on some form of I run the Arr suite, Sabnzbd, and a torrent client in Docker on a separate VM because it lets me run everything over an OpenVPN connection. Here’s an automated script I tweaked to get you started: For DR, create a fresh Debian LXC container to install Proxmox Backup Server into locally. Note: Everything to be run as root. So I have a theoretical question about the level of separation of systems. Using a VM for Docker gives more Docker/LXC let you set memory/cpu and other limits, so you can make it so an overloaded container can't take down the node. Plex transcoding with Docker - NVIDIA GPU - TiZu Tech. Quoted from the Documentation: "If you want to run application containers, for example, Docker images, One major reason you want to run Docker in LXC is passing through the iGPU for hardware acceleration. The latter is much easier, but uses more resources. But I have had to do that precisely once Run docker in Debian which comes with proxmox Run docker in LXC Run docker in a minimal Ubuntu/openSUSE/CentOS vm. Edit: we found a way to get this working (at least to some degree) by merging a docker image's file system onto an existing lxc template's file system and then packaging that back up as an lxc template This approach offers several advantages, including improved resource utilization and simplified management of Dockerized applications. The choice between these is subjective and mostly a toss-up. In general anything open to the internet I definitely do VM just for Our offerings align well with both Proxmox LXC vs Docker environments, catering to diverse user requirements.

On the VM (no LXC in my case) In Proxmox UI: Of course turned off ballooning, passed the whole iGPU as PCIe & everything on. Alternatives. Have done a bunch of preparations on a temporary server (notebook), and one of this is installed Tailscale in a LXC in proxmox as an app (so not in a docker container). It does not require the disk space or other resources as full VMs. I heard some stuff about it being not secure, but I think most of it was the typical problem of people thinking all containerization is an instant silver bullet to security problems; i. Install docker on ubuntu server and run it from there. It runs on Debian which comes with glibc. Among the plethora of options, LXC, Docker, and Podman have emerged as foundational technologies, each offering unique benefits for developers and system administrators. I have a similar use case at home. Built on the strong foundations of KVM (Kernel-based Virtual Machine) for complete virtualization and LXC (Linux Containers) for lightweight containerization, Proxmox offers an integrated People here recommend against docker inside an LXC because the official ProxMox documentation recommends against it. Very nice. How to Set Up Docker on a Linux Container (LXC) in Proxmox. LXC containers preserve state automatically. Big_Stingman comments on Plex setup through Docker + Nvidia card, but hardware acceleration stops working after some time. With proxmox you get the same concept as Docker on Ubuntu, but with an extra layer that allows for repeatable, and recoverable operations. While it started out being built on top of LXC, Docker later moved beyond LXC containers to its own execution environment called libcontainer. Double containerisation but it's more flexible than using a VM while getting the benefits Proxmox offers which you wouldn't get when installing docker directly in Proxmox Docker on Proxmox: VM vs. My current/old server setup is running Unraid so all of my Docker containers have run directly within Unraid for several years. That's just based on knowing that proxmox CT is an LXC container, and some benchmarking I saw years ago said the LXC was faster than docker (I think they said there was some weird extra stuff in the networking in docker that slowed it down, but that was a while ago so I might be remembering that wrong). Containers, which offer an environment as close as possible to the one you’d get from a VM, but without the overhead that comes with running a separate kernel and simulating all the hardware, but running Docker in LXC is I just recently moved Nginx Proxy Manager from running in Docker to a dedicated LXC container. At the moment I run Plex, qBittorent, an IRC client, Calibre-Web, and a few miscellaneous services. I have a new "server" arriving soon and being I have already build a home server with Docker (I make In summary, while both LXC and Docker can be used to run Frigate, LXC is often the preferred choice for its performance benefits and more straightforward hardware access. Bei Docker habe ich Watchtower am laufen, um die Container automatisch aktuell zu halten. What is LXC? Linux Containers , or LXC, is an advanced virtualization technology that utilizes key features of the Linux kernel to create lightweight and efficient isolated environments for running multiple applications on a Docker is a container method designed for one application.

Anyways, no one seems to push podman, LXC, k8s, vs Docker and I’m just curious if it’s really the defacto standard or if it’s just more “compose n go” mentality. As you said, plenty of documentation for installing docker software is out there. I ran Proxmox for host OS. I went for the VM inside Proxmox for HA OS and an extra layer of Install docker/Portainer nested within a non-privileged container (must be on PVE 7. Personally, I do both - I have a hypervisor running on my hardware, and then I deploy apps inside the VM using Docker. If OP just wants to spin up Docker, because of ease of setting up, go for Docker+VM. Skip down to the section on installing Docker to complete the installation. Underlying LXC is cgroups. If anything goes wrong, you can quickly restore your Proxmox Container to a The official PVE FAQ recommends to place docker containers in VM's. unless you just don't care about performance I mean, candy-canes go in the mouth but maybe another orifice wants to be pepperminty Proxmox>LXC>Docker>services Proxmox>LXC>Services The choice between LXC containers, VMs, and Docker with Portainer in Proxmox ultimately depends on your resource availability, security needs, and the nature of the workloads you plan to run. I’ve read that LXC would be less secure than running a VM. Using a standard LXC container or opting for the Nextcloud CT template (debian-12-turnkey-nextcloud_18. KVM and I also agree with this). Question Hey all, It is a little more of a hassle, but it is easier than trying to back up each lxc on each proxmox server individually, plus have space for multiple individual lxc backups. Pros Better backups: Proxmox provides a backup server capable of backing up virtual Installing Docker on a Proxmox LXC with Helper Scripts in 2 minutes; Installing Docker on an LXC or VM manually; Learn how to use Docker; What is Docker? Docker is a containerization platform that allows you to run applications in isolated environments called containers, which share the host's operating system. I’m curious if this is required, or, if not, what the pros/cons of using a VM vs a linux container (LXC) are. I have debian and alpine lxc templates and even NFS is very well supported lately. Proxmox VE vs XCP-ng. Just login to the web gui and click "create CT" in the top-right corner to create an LXC container. Also that docker image is usually maintained, and usually updates in place.
