Proxmox lxc vs docker. yml between several LXC containers.
● Proxmox lxc vs docker These contain a full OS except for the kernel which is LXC via Proxmox is great for stateful deployments on baremetal servers. Plus networking under LXC is a breeze. LXC with Nextcloud on there and mount my ZFS drive in the container. Let me know in the comments This approach offers several advantages, including improved resource utilization and simplified management of Dockerized applications. tar. overlay2 should be the default driver and should not cause any problems with any docker image. Someday in the future I Apparently the key point is whether the host filesystem is ZFS. Our solutions allow Obviously you can run all your containers under a single lxc, but 1) the proxmox interface only shows lxc's and not docker containers so it's easy to manage services if they're split and 2) fully separating the containers into separate lxc's means if you're doing anything nonstandard with your docker install you don't fear boring the whole thing. That doesn’t mean you can’t do it, just don’t come crying to ProxMox if you do and it breaks! I created the zfs volume for the docker lxc, formatted it (tried both ext4 and xfs) and them mounted to a directory setting permissions on files and directories. I ran Proxmox for host OS. Docker’s introduction marked a significant shift in virtualization technology, offering a As you said, plenty of documentation for installing docker software is out there. Then docker (installed on host OS) for the rest of the apps. Scripted lxc vs. The main difference between the 2 is that LXC containers are very much like a virtual machine, but significantly lighter weight since it is sharing the host kernel with the LXC host. Via Docker; there's no app install just a "docker create" and the setup is done. With LXC, Proxmox host can easily mount those volumes locally to get access to all the user data. This comparison of LXC vs Docker helps to differentiate between the two types of containers and their use cases. Docker, on the other hand, is a popular containerization platform that enables developers to package applications and their dependencies for quick Hi everyone, I am running pfSense as a VM on proxmox on an AliExpress box and after a lot of stability issues, it seems like I have gotten this thing stabilized - 12 days and counting (knockonwood). Proxmox is a great solution if you want to quickly spin up discreet VMs. Underlying LXC is cgroups. LXC is the name of the kernel feature that LXD uses to do its thing. 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. We love him anyway but we don't trust him with anything important. x+) for some juicy docker-on-lxc inception action. The before and after were on the same host. I use both LXC and Docker. But when you don't need that and when your use case is simple LXC is a good choice. 2. idmap = g 0 100000 1005 # we map 1 uid starting from uid 1005 onto 1005, so 1005 → 1005 lxc. Note: Everything to be run as root. What exactly is the reason VM's are recommended? Here some pros and cons I can come up with, and I like the help of the community to put together a post that gives an We will look at a few of the advantages of Proxmox and Docker below. Let’s compare running Docker in a virtual machine vs. "Best" is going to be subjective here. From a resource usage perspective, this is my favorite way of running Nextcloud on Proxmox. Proxmox I believe advises running application containers inside a full VM. 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 Is it lighter to install 4 LXC vs VM (Debian?) with 4x Docker containers. While it started out being built on top of LXC, Docker later moved beyond LXC containers to its own execution environment called libcontainer. I'd love to get some comparison charts of that transcoding performance, in other Words, what's the cpu performance bare metal vs. Why Use Proxmox? Proxmox offers several advantages over Docker. I did port a windows vm from VMware to KVM and it was fine for as long as I Sounds a bit double but I personally have docker running inside of a lightweight LXC container. However, there are tons of tutorials on using CT (LXC) to run Docker containers on Proxmox. g, ubuntu with console / TTY) and set the “Privileged mode” under runtime and resources the container starts in the 103/docker2 but in I have been reading a lot about how it is not recommended to use podman or docker in a lxc. The basic difference is that docker is about containerization of an app whereas LXC is about containerization of a whole system. I learned about Proxmox LXC containers, and I understand that the approach is different than how we used to host Docker containers in Portainer. I’m curious if this is required, or, if not, what the pros/cons of using a VM vs a linux container (LXC) are. Because as it is right now, I get horrible cpu-z performance in my hyper-v vms, which corelates negatively in People here recommend against docker inside an LXC because the official ProxMox documentation recommends against it. for each solution there is a more or less good documentation on the web. Quoted from the Documentation: "If you want to run application containers, for example, Docker images, itis recommended that you run them inside a Proxmox QEMU VM. I really enjoy Proxmox and it served me really well in the past 3 years. For LXC, let proxmox handle the work. Monday at 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 a slightly controversial idea. Docker is much more established, however. Proxmox LXC containers are lightweight, efficient, and run processes with isolation without the need for a full guest operating system. We To name a few I've encounter last year: nested docker, pptp vpn, bind mounting proc in user namespace. Using LXC containers you can quickly spin up 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. I set up Wireguard on a Ubuntu VM last week and it's working fine. Through a powerful API and simple tools, it lets Linux users easily create and manage system containers. As I mentioned before, while it is possible to run a Docker instance within an LXC, it’s not really recommended by Proxmox, not endorsed on official If you have used Proxmox, no doubt you know the containers you can easily create in Proxmox are LXC containers. And then, using kvm / proxmox or going with docker ? I need a GUI in remote access for the VM, so I can manage them when I'm not on site. 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. LXC is a Marty Stu that everyone loves to hate so they continue to use Docker. In this article, we will 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. Proxmox VE: Installation and configuration The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well as quick enterprise support. Reply reply Simply put – saving resources. it think lxc and directly installed plex is the most slim solution and easy to passthrough hw for transcoding. Step 1: Set Up LXC Containers. It's very easy to backup entire containers with the state (SQLite, Postgres dir) to e. If you would need as much as possible uptime, you can back up just rootfs disk while Docker data back up using restic or other backup tools. github. Have had many issues with docker in LXC breaking for no apparent reason (even restoring from backup had no result). The first step in installing Docker on Proxmox is to set up LXC containers. KVMs lacking the kernel - sharing the Debian-Proxmox kernel (Proxmox suggests running docker in a VM, i. But if you tick the right two or There is a bug in the version of the Linux kernel that Proxmox uses that prevents the br_netfilter kernel module from being namespaced correctly. 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. I even got 2 more VMs: HomeAssistant and 3CX. Method 1 involves using LXC (Linux Containers) in Proxmox to run Docker. Everything seems to work fine with the container, but backups always fail and I can't figure it out. What Is Proxmox? Proxmox Virtual Environment (VE) is a type-1 Linux Containers (= LXCs) and docker containers are something completely different. A hypervisor cluster running the container host as a VM (i. Running docker in LXC works alright, but you can face some issues with UID and GID, especially towards remote shares. I know that LXC containers share resources from the host # uid map: from uid 0 map 1005 uids (in the ct) to the range starting 100000 (on the host), so 0. Containers in Proxmox are LXC, actually. NAS (and with Most of the guides I see for installing on proxmox are using a VM. Don't know if that's in the Proxmox UI these days as I'm not on 7 yet. Does anyone know if this has changed? I don't have a lot of experience with Proxmox, but I was wondering if it's possible to share a docker network created with a docker-compose. Dec 4, 2024 11 3 3. gz)? 3. TLDR: Using Proxmox 8. It works for most, but DO LXC ANYWAY! gosh; lead a horse to water if it doesn't drink let's drown it ungrateful damn horse. The official PVE FAQ recommends to place docker containers in VM's. Thoughts? Just looking for efficient operation without doing things the "wrong" way. However, you can use your favorite Linux distro, like Ubuntu, and install LXC containers. Again, it is recommended by the Proxmox team to use a VM as opposed to an LXC for long-term stability, though many have used LXC containers and experienced no issues. I just started using the second VM for a docker that isn't a add-on (yet). 2 (or newer) no workarounds are needed. As for OPs requirements, I'd say go for LXCs on every single occasion. LXC, is a serious contender to virtual machines. LXC is a container technology that provides you lightweight Linux containers and while Docker is a single application virtualization engine based on the container. LXC, as well as I learned about Proxmox LXC containers, and I understand that the approach is different than how we used to host Docker containers in Portainer. I most often use LXC containers on my Proxmox home server and wondered which of the Debian or Ubuntu operating systems is best suited for this? Which of these operating systems in the LXC 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. When it comes to virtualization and containerization technologies, two prominent platforms stand out: Proxmox and Docker. I had to apt install skopeo and Docker is a container method designed for one application. Both Docker and LXC do the same work: they run a process (one or multiple) from a given image file, contained using Linux cgroups, namespaces, etc. 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. 5. Just login to the web gui and click "create CT" in the top-right corner to create an LXC container. Both offer unique features and benefits that cater to specific user needs. Convert Docker image to Proxmox lxc I know, I know, everybody asks about running Docker images in Proxmox, but I haven't found anyone addressing this approach yet. Docker is the kid with one eye that doesn't work that knows 4 words and has two working legs but doesn't use them. Having a whole VM just dedicated to Wireguard seems excessive though. LXD is a container method designed for containerizing many Linux systems. i like lxc and docker because it is simple (deploying a container, update and manage) and if you have more Proxmox officially recommends running Docker inside VMs. And getting docker running should be the only Under the hood proxmox and unraid use the same technology, so performance should be same. Very nice. (I am running Proxmox and run Docker in an LXC container. 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. Proxmox will feel more similar to someone who's used to more traditional virtualization like VirtualBox or VMWare. Docker excels in ease of use and portability, making it great for rapid deployment and scalability. This guide assumes you have an functional Proxmox environment and knowledge on how to harden I installed proxmox on a small desktop machine with single NVME SSD, just to try out. RHEV/oVirt, Proxmox, or ESXi). Or even without proxmox, just Ubuntu and docker. Unlike Proxmox, which focuses on LXC vs Docker-VMs . Just about all Docker issues can be solved by understanding the Docker Guide, which is. I ended up setting up an Debian Docker VM because of some restrictions for an LXC - when it comes to access shared folders and stuff - with PaperlessNGX eg I ran into problems. I added a mount point into this LXC created from a Running Docker in VMs vs LXC Containers: A Quick Comparison. Hi, I have a proxmox server with two fresh Debian 11 LXC container: 103/docker2 → is an unprivileged LXC container 104/docker3 → is a privileged LXC container Now the problem when I try to run a test container in portainer (e. The underlying technology behind LXC and Docker is the same. Best used with ZFS raid, with quotas and lazy space allocation backups are small or capped. They're not supposed to be compatible (LXC vs docker) but I do recall seeing a ducttaped solution to do this. There is probably very little difference in performance, so again now down to things like the ease of spinning up VMs and containers, etc. ) I made this transition because I wanted to use Crowdsec with NPM and found it easier to install all of Is LXC better than Docker? When you look at the LXC vs Docker debate, you will know that they both have their strengths. run docker nested in proxmox, best out of both worlds. But not all things work nicely in LXC’s, and sometime docker containers are the simple answer which is why I do have ~8 docker containers running inside of my “docker host” Ubuntu server VM. Search for the core template and click Not that long ago running docker inside LXC on top of ZFS was causing stability issues as well as excessive disk usage and on the proxmox forums the proxmox devs officially recommended against it. Update 20241104: As per #1490 (reply in thread) this workaround is no longer needed and in fact may produce issues on the latest PVE version(s). LXC produces entire kernels inside the hyper visor kernel. When looking at Proxmox container vs VM functionality, it covers it all. 101004 (host) lxc. This will give you all the Edit: I was on mobile before so let me give a bit more detail. We tried to follow the logic that a Docker container in an LXC container provides the fewest layers of abstraction between the hardware and the container whilst also providing isolation from the host OS. Should be done: by installing any Operative system LXC or by using the Docker LXC . There are two main types of LXC containers: privileged and Frigate Proxmox Docker Vs Lxc Comparison. LXC containers. That is the main difference between Docker + Portainer and Proxmox + (LXC) containers. Thus, it allows you to run a complete OS inside a container I haven't researched it further but i read it in a book about proxmox or the documentation, can't remember exactly. Neither is acceptable to me. All the further management goes through Proxmox LXC tools. If you don't know why Docker isn't a good solution for your workload, it probably isn't. Redswitches recognizes the significance of containerization for modern app development. ZFS+LXC+docker doesn't play nice according to some reports. moving your LXC manually is roughly similar, but I assure you, that Alle Container unter Docker nutzen die der VM zur Verfügung gestellten Ressourcen. TypeScript is a language for application-scale JavaScript development. 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. LXC vs. yml between several LXC containers. LXC containers? Docker is focused on applications and LXC containers are focused on distributions and more VM-specific functionality. 0-1_amd64. LXC, or I'm using it on my HomeLab as well. technically lxd can do containers and vms but in reality the usability still lacks behind and proxmox is much more evolved bynow. The “Proxmox Container Toolkit” (pct) Docker images, it is recommended that you run them inside a Proxmox QEMU VM. Using a standard LXC container or opting for the Nextcloud CT template (debian-12-turnkey-nextcloud_18. Used built in ZFS for file shares (NFS and SMB), LXC for firewall/router, and Pi-hole. lxc vs. Plex GPU transcoding in Docker on LXC on Proxmox - jocke. Login +63288668080; Send Support Tickets Running Docker inside a LXC on Proxmox has many benefits. That's just easier to me 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. After the 512mb mem it just depends on what application I have running in the VM. NATIONAL SUPPORT. How to Set Up Docker on a Linux Container (LXC) in Proxmox. Proxmox also uses LXC, but not LXD, to make its containers. 1. That explain the reason why we have done this performance comparison between LXC and KVM to better understand where we should use KVM and where we should use LXC. g. Docker. I assume running apps in a VM vs LXC The advantage of docker vs “plain” apt-get is that all the dependencies are built into the docker image, i. ). Sort by: but I was in a similar boat. Same for Wireguard. How much RAM do each require? I'm guessing VM Debian+Docker might be anywhere from 3-6GB RAM. I'd avoid it though even if possible Most people say Proxmox > VM > docker install > Container. It’s a deeper abstraction that the former two. LXC Container with Docker: Is there an advantage to using Docker within an LXC container? Pros and cons of this approach compared to the other options? 4. 4. If anything goes wrong, you can quickly restore your Proxmox Container to a Previously it was Proxmox > vm > docker If you have hardware resources limitation, then just do vm > docker. it offers a lot of control over settings etc. Linux with Docker & KVM/QEMU or Windows with Docker & Hyper-V). I went for the VM inside Proxmox for HA OS and an extra layer of For example I had no issues running docker in Proxmox 7. You can even run docker within Proxmox VMs. I am wondering if there is any big performance difference between running multiple websites with docker and npm comparing to running docker and npm in bare metal. I'm running my web apps on Docker on LXC on Proxmox. Edit: Typos Vs lxc seems be more like a "vm" approach to containers. Resource Efficiency: LXC containers are generally more resource-efficient than VMs, as they share the host system’s kernel and use fewer resources. You can learn more about Proxmox LXC containers vs. Even if you do not use firewall in Proxmox you must enable it (just set Best performance is probably the proxmox CT but I haven't actually tested it. Für jede Maschine in Proxmox muss ich RAM und CPU genau festlegen. I want to integrate docker/podman with a proxmox guy, as it's very annoying to constantly climb back and forth, I want everything to be in one place. hyper-v. KVM and I also agree with this). This will give youall the advantages of application containerization, while also providing thebenefits that VMs offer, such as strong isolation from the host and the abilityto live-migrate, which otherwise isn’t possible The Proxmox hypervisor natively supports two types of virtualization: Proxmox CT or LXC (Linux Container) and KVM (Kernel-based Virtual Machine) VMs. 1004 (ct) → 100000. Sounds like you're down to the choice between Proxmox with a NAS VM or TrueNAS bare metal. In this comprehensive comparison guide, we will explore the differences between Proxmox LXC and VMs, helping you make an informed decision for your virtualization needs. Most things in proxmox can be done with LXCs or docker installed on an LXC Reply reply Most issues with LXC+Docker result from the complexity of double namespacing and double access rights, which people get hung up on, especially if they just follow some guides. If you are resource constraint, use an alpine vm. If you plan to run multiple KVMs/LXCs you need plenty of RAM (suggest 32G to 64G) and no more than 16 cores, unless you will be running CPU heavy apps, in which case even 32 Separate LXC for each service with the service being installed in the container directly Single LXC, install docker, run all of the services in docker Single VM with docker and run all of the services in docker I currently have them set up in 1. Follow the step-by-step guide below to seamlessly deploy Docker on Proxmox using LXC containers. docker . This makes LXC containers a more If you want to run application containers, for example, Docker images, it is recommended that you run them inside a Proxmox QEMU VM. . docker successfully installed and running but that warning message appears in the proxmox host and I don't understand, why?! In the docker lxc, docker info shows that overlay2 is used. LXC containers preserve state automatically. Today's mission was to get an i5 nuc w/ proxmox installed. In this article, the author mentions a method of converting a docker image to lxc using lxc-create <<name>> -t oci -- --url docker://alpine:latest . com) then the documentation suggests you run Docker inside a VM. (LXC vs LXD vs Proxmox Containers vs Docker) There are also numerous posts here in the forum that recommend to use VM's. This will give you all the advantages of application containerization, while also providing the benefits that VMs offer, such as strong isolation from the host and the ability to live-migrate, which otherwise isn’t possible LXC vs Docker. Explore the differences between Proxmox Docker and LXC for Frigate, focusing on performance and use cases. I have 8 different LXC containers and 5 VMs that all back up without issue, so it is something about this container, or Docker, or something. " One major reason you want to run Docker in LXC is passing through the iGPU for hardware acceleration. It does not require the disk space or other resources as full VMs. It's the lesser evil, imo. Docker aims at running a single application in an isolated, self-contained environment Proxmox VE also integrates seamlessly with KVM and LXC technologies, offering flexibility and scalability for virtualization needs. I am interested in this because I also started migrating from a single VM with all docker containers inside it, to one lxc container per stack (ex: grafana+loki+promtail+prometheus+alertmanager) I have docker installed in a debian LXC container on my Proxmox host. With proxmox you get the same concept as Docker on Ubuntu, but with an extra layer that allows for repeatable, and recoverable operations. Proxmox Container Backup and Restoration. I need to think of docker/podman containers as containers in the left pane, have an attachment to them by clicking a button, as in lxc, access to parameters, etc. Docker is dumb as a box of rocks but popular. Proxmox VE (Deutsch/German) . It is simple to back up the entire LXC container with Proxmox if you can have planned downtime. Sure, you can get docker work in LXC with today's workaround. idmap = g 1005 1005 1 # we map the rest of 65535 from 1006 upto 101006, so We’ve set up several Proxmox LXC containers to host several WordPress sites on our server. Learn about the latest Proxmox updates for Frigate, enhancing performance and stability for your surveillance system. I have an eye on the scripts from u/tteckster https://tteck. Install docker on ubuntu server and run it from there. The Proxmox route is more capable but requires more knowledge thus can be harder for some users. I know it’s not the advised strategy. And its efficiency, features and technical advantages. If I make a VM, adding the SMB drive is all done normally within the VM. Proxmox Virtual Environment. 04 and still be able to run the most recent version of all software without being blocked by dependencies (or having to rely on unofficial repository). It IS possible to get an LXC run root with UID 0. I run Proxmox, I'm debating re-doing it in an LXC container. First, it has an awesome, web-based user interface that makes managing virtual machines and LXC containersextremely straightforward. Proxmox - 10. The images and container files will remain on the system storage, but Docker somehow looses awareness that they exist. NAS (and with TrueNAS then to S3/B2). LXC and Docker are two different technologies that achieve similar results, up to a certain point. io/Proxmox/ Is there a big difference in performance between an LXC and a docker container in a VM? I just recently moved Nginx Proxy Manager from running in Docker to a dedicated LXC container. 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). This means that the module cannot be imported within an LXC instance and therefore you cannot currently run Docker correctly within an LXC instance on Proxmox. Friends, I would like to know where you place your services. I have debian and alpine lxc templates and even NFS is very well supported lately. Which apps are best as LXC containers or deployed inside a VM as a container. To setup and install Docker in a Proxmox LXC Conainer, you will have to download the Turnkey Core template to your storage. Run docker in Debian which comes with proxmox Run docker in LXC Run docker in a minimal Ubuntu/openSUSE/CentOS vm. as far as I know, Docker in LXC isn't any worse than Docker normally. Personally, I am a fan of LXC, although I admit that Docker has its uses. Hallo, ich habe nun meine ersten Gehversuche auf Proxmox hinter mir und bin erstmal sehr zufrieden, einfach auch, weil es funktioniert. Makes it easy to backup, migrate and manage resources docker is able to use. LXC Container: Choosing between VMs, LXCs, and bare metal for running Docker in Proxmox depends on your specific needs and environment. Install from scratch on LXC Container LXC are system containers, i. Explore the differences between Docker and Proxmox for virtualization needs, analyzing containers, VMs, and which suits your DevOps goals. Hi guys, I am migrating my home assistant and a bunch of docker containers from my synology nas to the proxmox platform. Unraid is more a energy saving optimized NAS with a Nextcloud runs really well on Docker, and if you’re using Proxmox, you can easily configure an LXC Container to run Docker, then install Nextcloud on top of it. Or a Docker host. If no templates are available, click on your storage, click content section, then click "templates" at the top. LXCs are system containers. The impression I’ve gotten from setting up other services I am also thinking of running these services as Docker containers inside the LXC containers, because maintenance, updating or changing config is easier with Docker containers than running these services "bare metal" in the LXC containers. VMs offer strong isolation and advanced features like live migration In this article, we offer an in-depth comparison between Proxmox container vs Docker, focusing on unique features, use cases, and benefits they offer. So far so good and the performance is great but the move to LXC from Docker feels like a step back. LXC and Docker can both be configured securely or unsecurely. Virtual Machines here. I personally also run docker and CasaOS from a full VM when in Proxmox. Docker is not supported directly. Docker is unique. Even though LXC and Docker solve different use cases, there is enough similarity to inspire conversation (multiple subreddits have numerous "LXC vs. Proxmox (7. It just streamlines so much and avoids the layer of abstraction you will LXC vs. Install docker/Portainer nested within a non-privileged container (must be on PVE 7. Docker" questions); you're not alone there. you can install plex directly on ve (not good), in vm, in lxc, in docker on lxc or vm. Docker LXC vs LXD vs Proxmox Containers vs Docker LXC is a userspace interface for the Linux kernel containment features. Proxmox VE uses Linux Containers (LXC) as its underlying container technology. By 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 lxd as a tech is great but proxmox as a overall user experience or whatevr you want to call it is still much better. Jetzt hat mein kleiner Proxmox Test Mini PC 32 GB Ram und eine 8-Core CPU. 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. 1 Computer with isolated applications (Docker). I googled around ways to install docker and found 2 ways apt install docker directly via proxmox shell, or install turnkey core and add docker on top of that. Proxmox(on Debian), can run many Ubuntu (Computers/OS) with many containers (Docker). There is one difference here. But if you have a few node, you could do a cluster of kubernetes, proxmox handles the networking very well. This is a simplified guide to installing Portainer within a Proxmox LXC for homelab use based on my personal notes. Let me know in the comments Our offerings align well with both Proxmox LXC vs Docker environments, catering to diverse user requirements. Thread starter PVE-Newbee; Start date Monday at 23:22; Tags docker docker lxc lxc Forums. Run docker in a VM. In general anything open to the internet I definitely do VM just for Proxmox and Docker solve different problems, and using both together is not a problem. I want to utilise Proxmox's firewall on that container to improve the security of my setup. It also excels in creating and managin Both LXC and Docker are effective container technologies, and the choice between them depends on your needs. If OP just wants to spin up Docker, because of ease of setting up, go for Docker+VM. On my synology, containers such as node-red, zigbee2mqtt, esphome etc - have the same IP address as the synology host I have a similar use case at home. This is good feature to have in certain The downside I see is you need to use the hosts kernel which already destroyed docker once after a Proxmox update. And Docker and LXC container Max 1GB RAM each (probably <500MB). Proxmox is more powerful when it comes to more advanced vm features, like snapshots, clustering, etc. Install docker on Proxmox and run it from there. That's why I have a Docker LXC and Docker VM right now. Ubuntu with Docker is 1 OS with many containers. They may sound 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. On the other hand, Portainer focuses on Docker container management and provides essential features for effectively managing containers, such as resource utilization monitoring and user access control. 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 it a Container template. Plex transcoding with Docker - NVIDIA GPU - TiZu Tech. LXC, as well as the former OpenVZ, aims at system virtualization. but competition is always good so maybe both can evolve in th near future The choice between LXC, Docker, Podman, Portainer, and Rancher hinges on specific project requirements, performance needs, and security considerations. Docker and Proxmox best practice comments. This has advantages but also disadvantages. Beim "Ansatz 1 LXC = 1 Dienst" muss ich jedem Container die Ressourcen zuweisen. 57 (macvlan bound to eth0) I have a container If you want to use Docker with Proxmox you have 3 options: run Docker in VM, run Docker in LXC, or run Docker directly on the PVE node. What would be the most secure option? Is there a difference if I install docker on Proxmox or in an Ubuntu VM? Security? Speed? Reliability?
