Proxmox lxc vs docker. It has its quirks, but I'd definitely recommend it.
Proxmox lxc vs docker Proxmox, on the other I ran a few storj docker containers in Proxmox alongside LXC containers and KVM VMs without any issues for years. So the LXC would need to be Privileged which comes with it’s own risks. Shape your 2025 cyber GRC strategy with a complimentary Gartner report Download Now Looking to streamline your Running docker in LXC is advised against by the proxmox developers. An lxc is a container. Ive ordered a Firebat I have a Docker LXC (Debian 12) and a separate Ubuntu 23 LXC for JellyFin (because I needed to pass through a 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. On the other hand, Portainer focuses on Docker container management and provides Lately I've been moving some services to Proxmox LXCs to benefit from hardware-acceleration shared between multiple LXCs (e. HAOS is easier to maintain and I have plenty of resources to run it in a VM so there is no concern there. Proxmox is a great solution if you want to quickly spin up discreet VMs. the Proxmox server itself. ) I made this Best practice to run Docker, according to Wiki, is to use a VM and not a LXC: If you want to run application containers, for example, Docker images, it is recommended that you run them inside a Proxmox QEMU VM. Alle Container unter Docker nutzen die der VM zur Verfügung gestellten Ressourcen. I wonder if you can run Docker (OCI) containers within an LXC/LXD environment. g plex and tdarr are now both running as CTs). Simple platform Ya agree, docker concept is more like declarative assembly of software stack using pre assembled images. LXC containers are more resource-efficient than full-fledged VMs as they share the kernel with the host, i. Docker is much more established, however. That solves a lot of issues, then on the docker image just set the UID/GUID you need. How much RAM do each require? I'm guessing VM Debian+Docker might be anywhere from 3-6GB RAM. These contain a full OS except for the kernel which is Choosing between VMs, LXCs, and bare metal for running Docker in Proxmox depends on your specific needs and environment. Both options have their unique advantages and considerations. Disabling some app armor defenses isn’t ideal, but I am just about to setup my second docker host in my proxmox cluster and would like to do it the best possible way. Through a powerful API and simple tools, it lets Linux users easily create and manage system containers. Reply reply _mynd I try to avoid docker-style pods/containers unless I'm working with K8s. My filesystem for Proxmox containers and VMs is ZFS. Hello Im fairly new to proxmox and are planing to put it at base for a few computers in my home lab. In this comprehensive comparison Our offerings align well with both Proxmox LXC vs Docker environments, catering to diverse user requirements. For LXC, let proxmox handle the work. Vs lxc This. io/Proxmox/ Is there a big difference in I run HAOS, you can run HA in a docker container/LXC, but not HAOS. Underlying LXC is cgroups. 2 want to run a few applications as docker containers but save the overhead a VM would bring by having Docker inside a Proxmox LXC. And Docker and LXC container Max 1GB RAM each (probably <500MB). I run Plex on Proxmox via a Debian Docker VM, plus all the various arrs etc, total of 18 docker containers on one VM. I run LXC, Docker, and some full VMs in my environment. As I am using SMB/CIFS within some of my docker-containers If you want to run application containers, for example, Docker images, itis recommended that you run them inside a Proxmox QEMU VM. I'm looking to migrate from XCP-NG to Proxmox. This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent I have personally walked both roads and I feel VMs give me a better , more stable environment for the docker Not sure it totally answers your question - but I was in a similar boat. Setup is relatively easy and straightforward. However, inside Proxmox, IMHO there is no point in not using LXC, since it's very well integrated into the platform and provides awesome results and performance. Isn't LXC better for Docker in terms of performances ? If you have done the tests what are the The choice between Proxmox and Docker ultimately depends on your specific requirements. In the new config, NPM runs in its own LXC. Docker is not supported directly. I'm at a point where Plex Is it lighter to install 4 LXC vs VM (Debian?) with 4x Docker containers. as far as I know, Docker in LXC isn't any worse than Docker normally. But if I just install Debian on bare metal, than I install docker and Tailscale directly on the server. You could also do LXCs, but if you’re more familiar with Docker (or NOT familiar with LXC), just spin up a VM and do Docker there. In one of the Ubuntu server VM’s I have docker containers. I never had an issue and no problems with updating all For Plex I So, using Docker inside LXC on Proxmox is a giant pain in the ass Actually, it's the ZFS part that's apparently the problem here. This article will compare their host machine utilization, simplicity, speed, security, ease of use, However, there are tons of tutorials on using CT (LXC) to run Docker containers on Proxmox. I see why you say that but I implore you to take another look at docker. This will give you all the advantages of application containerization, while also Docker/Podman produce reconstructable services inside the same kernel space so they’re very client-friendly. I have an eye on the scripts from u/tteckster https://tteck. I currently have a number of VMs running, one of which is an Ubuntu server with I’m running this setup using LXC and have been for years. The Proxmox route is more capable but requires more knowledge thus can be harder for some users. Docker" questions); you're not alone there. I run Proxmox, I'm debating re-doing it in an LXC container. Could find those two articles on how to accomplish that with an LXC vs LXD vs Proxmox Containers vs Docker LXC is a userspace interface for the Linux kernel containment features. This is what is officially supported either way. 8 This guide has been verified to work with Proxmox 5. Containers are best utilized when treated as immutable and then give them a persistent volume as needed, along with This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent API changes, which break third-party apps and moderation tools. LXC is often seen as a more “pure” form of containerization, offering system containers that closely mimic virtual The Proxmox hypervisor natively supports two types of virtualization: Proxmox CT or LXC (Linux Container) and KVM (Kernel-based Virtual Machine) VMs. So far so good and the performance is great but the move to LXC from Docker feels like a step back. 1. Especially if you use compose files, thats practically all you need to restore or make another instance of the environment with one command. 3, for both Ubuntu 22. I'm running my web apps on Docker on LXC on Proxmox. Resource overhead is minimal. Hallo, ich habe nun meine ersten Gehversuche auf Proxmox hinter mir und bin erstmal sehr zufrieden, einfach auch, weil es funktioniert. LXC with Nextcloud on there and mount my ZFS drive in the container. The impression I’ve gotten from setting up other services on my server is that an LXC is generally preferred as it has faster start up times and is more resource efficient compared to a VM. For me I just created a Ubuntu Desktop VM and I run Docker inside. The Architecture of LXC Containers LXC containers (Linux containers) are known for being simple and efficient. I’d recommend using docker inside a VM. Choosing between Docker and Proxmox depends on what you need in terms of performance comparison and managing resources. LXC via Proxmox is great for stateful deployments on baremetal servers. Also things Proxmox brings LXC and KVM. Having a whole VM just dedicated to Wireguard seems excessive though. However, if you prioritize lightweight application deployment, portability, and development workflows, Docker is the more suitable option. Personally, I am a fan of LXC, although I admit that Docker has its uses. Or a Docker host. Running a VM I run Proxmox and it works very well for me. However, there are tons of tutorials on using CT (LXC) to run Docker containers on Proxmox. It’s suited for environments where development speed matters. However, this also causes some problems: If (LXC vs LXD vs Proxmox Containers vs Docker) There are also numerous posts here in the forum that recommend to use VM's. As a longtime Docker user who recently started using Proxmox, some Heyo, Over the last two years I've gone from running Plex in Ubuntu Server to Ubuntu Server and Docker, to Proxmox as an LXC container with GPU passthrough without docker, while simultaneously expanding my library significantly. If you are resource constraint, use an alpine vm. What Is Proxmox? Proxmox Virtual Environment (VE) is a type-1 If you’re a Proxmox user, like me, then you’ve likely seen the “Create CT” button and wondered what it is - it’s not their own container technology, it’s not Docker, it’s LXC! LXC containers are really more like lightweight VMs and are most appropriate for longer-lived stable services. For immediate Explore the differences between Proxmox Docker and LXC for Frigate, focusing on performance and use cases. LXC, as well as the former OpenVZ Docker and LXC are both just kernel namespaces and cgroups, rather than full VMs (full VMs would run their own kernels on virtualized hardware). That being said, I've never run docker, so I can't speak to that. Everything seems to work fine with the container, but backups always fail and I can't figure it This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent API Among the plethora of options, LXC, Docker, and Podman have emerged as foundational technologies, each offering unique benefits for developers and system administrators. Aktuell laufen bei mir auf meienr Synology einige Docker-Container. Wanted to use proxmox VM backup for my lxc (debian 12) docker host - but didn't want to backup docker root dir and some container stack volumes (photo thumbnails, etc. LXC, as well as the former OpenVZ, aims The difference is that a LXC will share its kernel with the Proxmox host and as such, any hardware-level vulnerability in the host will expose the LXC CT and vice-versa. And docker creates containers. I have mu proxmox with docker and some LXC stable running since 2 years. Containception I’d avoid. When you start getting into things like wireguard or anything where you need relatively recent kernel features, it's much easier to stay on top of with a VM than try to shoehorn the features into the hypervisor OS. You can even run docker within • The Proxmox hypervisor natively supports two types of virtualization: Proxmox CT or LXC (Linux Container) and KVM (Kernel-based Virtual Machine) VMs. LXC Container: In this article, we offer an in-depth comparison between Proxmox container vs Docker, focusing on unique features, use cases, and benefits they offer. I think they all have their place. Please share your thoughts on I ran the test 4 years ago so I can’t recall what settings the LXC had at the time, sorry. I personally run my NextCloud instance as an LXC container with Ubuntu as a base OS and NextCloud installed from scratch. Run docker in a VM. That’s what I do, and it’s great.

My goal is no interruptions in my house, so I prefer to run it on the OS it was designed Simply put – saving resources. I'd avoid it though even if possible Most people say Proxmox > VM > docker install > Container. The only benefit is than you can quickly create LXC containers. I also never updated proxmox. 3 using zfs and now every time the server power cycles, every 24 votes, 33 comments. The memory and swap settings for containers can map directly to these values, whereas previously only the memory limit and the limit of the sum of memory and swap could be limited. See a blog post that describes the major differences here. Reply reply vs Docker on unraid. So the title really says it all, I want to know what is the best way to use Nextcloud on Proxmox I have Proxmox and I'm trying to get Nextcloud up and running. Almost all my proxmox instances at customer sites are local Hyper-V vms that only run lxc containers. Docker inside of an LXC is not VMs vs LXC instances Linux VM + Docker: Simplest / officially supported method Pros: 0% chance of cgroup incompatibilities between docker and due to LXC updates No additional steps / considerations to run overlay2 / fuse-overlayfs. I personally use Proxmox > LXC > docker install Docker in LXC vs VM upvotes · comments r/Proxmox r/Proxmox This subreddit has gone Restricted and reference-only as part of a mass protest against Reddit's recent API changes, which break third-party apps and moderation tools. It also excels in creating See more While LXC and Docker have much in common in terms of their architecture and usage, they also differ in many ways. I have a couple options: VM with Ubuntu Server, and create a virtual hard drive on my ZFS drive. Ended up doing Hi! I've recently switched from Ubuntu has my host OS to Proxmox. I find that this gives me significantly more flexibility than either a Hi, I'm running Proxmox 7. From As you said, plenty of documentation for installing docker software is out there. Docker is perfect for quick application delivery. Jetzt hat mein kleiner Proxmox Test Mini PC 32 My argument against option 1 is that if someone else needed to come in and look at the system (or even you later on), nothing in the proxmox ui would indicate that docker was installed, and the performance metrics would become confusing bc there would be some Should You Use a VM or LXC for Docker in Proxmox? Running Docker on a Linux Container saves resources on the host, is faster, and quite honestly, there’s no other reason to use LXC. They operate by creating a separate operating system environment within the host system to create I would choose LXC for those that are to be installed as normal packages (not Dockers) If something needs Docker then use a VM and inside that install Docker and any dockers you need. If you need full system virtualization and enterprise support, Proxmox is the way to go. 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 You just bind the LXC to user 0 instead of the 60thousandsomething, then mount the whole LXC in proxmox, and chown the whole file system to uid 0. For example, can't install Tailscale, on Proxmox host. If no templates are available, click on your LXC (LinuX Containers) is a OS-level virtualization technology and Docker is an extension of LXC’s capabilities achieved through a high-level API. I use Proxmox as the principal hypervisor solution for my Student organization which has its share of internal services and public applications. Docker is much more tailored to transient containers which are more ephemeral. First, it has an awesome, web-based user interface that makes managing virtual machines and LXC containersextremely straightforward. Resource Efficiency and Hardware Limitations If you have limited hardware — like a Proxmox server with a lower-powered CPU and limited RAM 28 votes, 17 comments. The choice between these is subjective and mostly a toss-up. More important is storage layout for your use case. We offer hosting Proxmox VE also integrates seamlessly with KVM and LXC technologies, offering flexibility and scalability for virtualization needs. Just login to the web gui and click "create CT" in the top-right corner to create an LXC container. I just recently moved Nginx Proxy Manager from running in Docker to a dedicated LXC container. My aim is to leverage LXC/LXD as the container Would love to see this happening in some form, but I also think that a lot of edge cases may pop up. Don’t try to force docker into Proxmox. Now that the system is created, you can install whatever you’d like on top of this! One of my favorite options is In the world of virtualization, Proxmox offers two popular methods: LXC (Linux Containers) and VMs (Virtual Machines). Have had many issues with docker in LXC I learned about Proxmox LXC containers, and I understand that the approach is different than how we used to host Docker containers in Portainer. Now I came up with a new "idea" to determine which option I should choose (VM, LXC or Docker). 0. NAS (and with TrueNAS then to S3/B2). I like Proxmox though because if I set up Wireguard on a Ubuntu VM last week and it's working fine. Running Docker in a Linux Container (LXC) will allow you to run Most of the guides I see for installing on proxmox are using a VM. ) For maximum confusion the CLI tool for LXD is I've been dabbling with LXC containers because they seem to boot and run faster since they share the kernel with Proxmox, but I also have an Ubuntu VM running with Docker and Portainer in it. What exactly is the reason VM's are recommended? Here some pros and cons I can Linux Containers (= LXCs) and docker containers are something completely different. I run moosefs for aggregating the various drives I have via 5 lxc container, thats accessible to plex via a network fuse mount. (LXD is a thing you can install like you install Docker. Never had an issue. 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). I’d say I’m 80% docker with a couple of LXCs and some VMs. I'm struggling with the recommended best-practice for networking between docker containers in a VM and an LXC (or docker on a separate host). Any update on the proxmox system can change how docker in LXC behaves. Thing is, when I'm using docker containers for production websites I want to use ZFS replication for the VM that hosts docker and also I can backup the VM more easily. ). Just installed docker, portainer and it ran just fine. So I would have to make a VM on top of Proxmox. I recently moved everything to a different server on 7. LXCs are system containers. run docker nested in proxmox, best out of both worlds. LXC produces entire kernels inside the While LXC can be used, I’m assuming you won’t keep everything you download in the LXC. Why Use Proxmox Proxmox offers several advantages over Docker. Here are some key considerations: Hardware Acceleration For Intel I know a decent amount about docker, but the learning curve for lxc is high and I haven't learned much yet, let alone what appears to be Proxmox's idiosyncratic approach to lxc. Today's mission was to get an i5 nuc w/ proxmox installed. I don’t know why, but I thought I couldn’t pass through hardware to LXCs, I should’ve probably tested first. Beim "Ansatz 1 LXC = 1 Dienst" muss ich jedem Container die Ressourcen zuweisen. Will you bind mount some storage I did Docker in an LXC for a while, switched to a VM. Proxmox also uses LXC, but not LXD, to make its containers. e. If you came here, looking for a way to get Docker to run on native LXC (without Proxmox), this guide will not work. The new Proxmox build has an 11th gen Intel Core i7 Best performance is probably the proxmox CT but I haven't actually tested it. 04 If Differences between Proxmox VE containers vs VM configurations, Docker, LXC containers Brandon Lee September 29, 2022 Last Updated: September 25, 2024 6 minutes read Most services initially ran on bare (crappy) metal but now are containerised via Docker. Certain things that call on the kernel will use the kernel of the host when you use an lxc. I do have a TrueNAS box for storage, but I purposely only access static files over the SMB share from it. I’m curious if this is required, or, if not, what the pros/cons of using a VM vs a linux container (LXC) are. Thoughts? Just looking for efficient operation LXC and Docker are two different technologies that achieve similar results, up to a certain point. Proxmox>LXC>Docker>services Proxmox>LXC>Services Reply reply SirEggington • Ah I see lol. It just streamlines so much and avoids the layer of abstraction you will find using Running Frigate in LXC is generally recommended over using Docker in a VM for optimal performance. VMs offer strong isolation and advanced features like live migration When comparing LXC and Docker, it’s essential to understand their fundamental differences. Redswitches recognizes the significance of containerization for modern app development. 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 LXC vs Docker LXC is a container technology that provides you lightweight Linux containers and while Docker is a single application virtualization engine based on the container. It has its quirks, but I'd definitely recommend it. We will look at a few of the advantages of Proxmox and Docker below. g. Which can cause issues down the line. On my old setup I've had everything running as Docker containers. (I am running Proxmox and run Docker in an LXC container. LXC is the name of the kernel feature that LXD uses to do its thing. The complexity of the setup requires careful attention to the Proxmox and LXC documentation. If you just want a server to run docker containers then I'd recommend a Debian lite server with Cockpit webUI. They operate by creating a separate operating system environment within the host system to create multiple isolated environments. I did some research and I found the following options to host Docker containers in Proxmox: 1-Create a LXC container , install Docker in it and make Proxmox is built in top of Debian but many things are removed. It's very easy to backup entire containers with the state (SQLite, Postgres dir) to e. 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. Proxmox official support would always recommend that you run Docker in VMs, but the disadvantage to that is that VMs require more resources from the hypervisor. Best used with ZFS raid, with quotas and lazy space allocation I have a similar homelab server and I run it on proxmox. I have truenas, multiple Ubuntu’s, home assistant, windows, etc all as VM’s. Install docker on Proxmox LXC vs LXD vs Proxmox Containers vs Docker LXC is a userspace interface for the Linux kernel containment features. For two years I’ve used Ubuntu lxc running docker on a Dell r420 using hardware raid on pve 7. They're not supposed to be compatible (LXC vs docker) but I do recall seeing a ducttaped solution to do this. Unlike virtual machines that require their own kernel, LXC containers share the host’s kernel, making them more efficient . Diese Dienste möchte ich sukzessive nach Proxmox umziehen. In fact, the Proxmox team 12 votes, 30 comments. Thanks for helping. EDIT/TLDR2 : After discovering that ZFS is not that flexible (you can't simply add one drive to expand the storage), I removed TrueNAS from the question and now I'm running 4 VM in my Promox : one OMV for storage, one Debian for Docker, one Debian for Choosing Between LXC, VMs, and Docker in Proxmox 1. github. Frigate Proxmox Update Learn about the latest Proxmox updates for Frigate, enhancing performance and stability for your surveillance system.
