Docker zfs proxmox docker Hi, I came across this post while trying to figure out how to mount my zfs pool to a container. It remains to be seen which would be the most stable and performant for running my VMs and a few LXC containers. Proxmox manages all drives via ZFS. On each worker node, install Docker by following the official Docker installation guide for Ubuntu. I know OMV6 the standard option to use the regular kernel and on install the system recompiles it with the ZFS hooks. #1245 one static IP –> opnsense –> proxmox –> debian 12 as VM –> mailcow-dockerized. You can run docker inside a guest on proxmox. Create a new LXC Container In Proxmox VE create a unprivileged LXC container with fuse=1,keyctl=1,mknod=1,nesting=1 (I&rsquo;m not sure if all are needed). 04 container. Proxmox VE 8. That'll be easier anyway. The Proxmox team works very hard to make sure you are running the best software and getting stable updates and security enhancements, as well Create a Linux VM, install docker and run Jellyfin in a socket container. Everyone has heard of Docker by now, it’s one of the most popular ways to create and run containerized apps and services. On the proxmox is running a not containerized server, also in @esackbauer i don’t try again zfs replications but why not. The opnsense, proxmox and debian VM are in the same subnet. x: Install ZFS Native; Proxmox: OpenVZ (OVZ) and Turnkey Appliances root password ZFS is killing consumer SSDs really fast (lost 3 in the last 3 months The Proxmox community has been around for many years and offers help and support for Proxmox VE, Proxmox Backup Server, and Proxmox Mail Gateway. With Linux, documentation for every little thing is in 20x places and very little of it is actually helpful. It looks like when docker is installed in an LXC on Proxmox with ZFS, the Docker Storage Driver (view with docker info) defaults to vfs. I had a lot of trouble migrating from TrueNAS to Proxmox, mostly around how to correctly share a ZFS pool with unprivileged LXC containers. But takes more resources. 0-0. iso USB-2 Hold of on installing Docker until after ZFS is configured, then create a ZFS datasets mapping to /var/lib/docker so that Docker will use the ZFS filesystem driver. Apparently the key point is whether the host filesystem is ZFS. Following the Proxmox manual , it also matches GRUB booting in UFEI mode. Install Docker inside LXC container - Proxmox VE. Containers are amazing. All previous workarounds should be considered deprecated. ZFS+LXC+docker doesn't play nice according to some reports. I To use docker on proxmox see this STH post: Perhaps not best practice, but I just run docker on the Proxmox host, mainly because there are some issues with the ZFS storage driver when docker is virtualized. With the bare-metal installation, you'll get a complete operating system based on Debian GNU/Linux, 64-bit, a Proxmox VE kernel with KVM and container support, great tools for backup/restore and HA clustering, and much more For a home server acting as a seedbox / media- / file- / server hosting services like Samba, NextCloud, Radar, Deluge, Sonarr, Plex, Calibre, etc. I also can't change the permissions in anyway. No dedicated drive for storing metadata. GitHub Gist: instantly share code, notes, and snippets. We have a quick guide and video here Setup Docker on Proxmox VE Using ZFS Storage. I tried it once and then I have to reinstall Proxmox CE. NFS mounts in every lxc docker swarm node on each Proxmox host with a shared dedicated storage server. Personally that doesn't bother me all that much. Btw, im running docker containers on Unprivileged lxc containers on ext4 backend storage since almost forever, and it worked always very perfect. I use restic together with resticprofile inside a docker container to backup my nas data to a hetzner storagebox and the native sync/backup tasks to sync my nas data to an USB drive I am running Proxmox on 2 NVMes with ZFS as the filesystem. The setup: I use ZFS for storage on my Proxmox hosts, and having to provision a VM or LXC means either dedicating a set amount of storage for containers, or overprovisioning the storage (set refreservation=0 on the volume) and hoping for the best (which also means ensuring the Docker VM/container uses fstrim regularly to return unallocated space to the host). Even if the \EFI\proxmox\grubx64. This doesn't look pretty in the OMV ZFS plugin, but is normal behavior. It hinders with proxmox. All this would run on Proxmox. Reply reply I've run into random problems with overlay2 with zfs via lxc. How do I give my root user in the My point is the they run Docker natively and the Docker volumes (persistent data) can sit on top of ZFS as first class citizens instead of having to use a bunch of layers of abstraction to make Proxmox work. Before I had all the rrr on the same pi with docker. Proxmox, with its good ZFS support and functional web UI, is the obvious distribution. Popular. files/tunes and I would like to mount it to /mnt/tunes in container 100 which is Plex. I think of Proxmox more as Debian with built-in ZFS support and a nice VM/LXC manager on top. For example: - it could be that an onlyoffice docker image won't work 50% chance. If the hardware dies, the ZFS pool import makes for quick recovery. After installing Docker, we will see that it automatically selects the ZFS storage driver: # docker info | grep Storage Storage Driver: zfs See more There is currently no way to get ZFS + Docker to work besides running on your PVE host with ZFS or in a VM with ZFS (inside your guest). Here the config: Docker. tar. So I wrote a how-to guide so I could refer back to it myself later on. Much easier than installing proxmox, then docker, then restoring docker containers. Running in a container might result in some functions not working properly. Docker isn’t difficult to use and understand but there are tools that exist that make managing, creating, and modifying docker containers even easier and After much internal debate and poc'ing where I can in hyperv between truenas 24. Lately im running even docker containers inside unprivileged lxc container with overlay2 and nesting only on zfs. Heimdall). Typical docker + portainer + portainer agent installation on debian runs under 150 MB. Setup is simple, 2 SSDs with ZFS mirror for OS and VM data. Here's my situation I have a pool with a datatset called /zpool/public. 1 the new-ct. 2 NVMe drives to 1 large CEPH pool? I've heard some amazing things on both sides and some nasty drawbacks.

Btw. 4. However, some I need to run over Docker (for example nextcloud, immich, mealie, gitenberg, tika). . Instead, I like to use Podman, a tool that allows us to run Dockerized images in an LXC with a really low performance penalty, while also providing us a whole host of other options such as ZFS on Proxmox, or a VM with TrueNAS, or an external NAS/storage? Proxmox and Docker are two different animals, and although you can run them in parallel and even run Docker inside a Proxmox container with relative ease, it doesn't seem Worth Mentioning. There is an easy fix to change the Docker ZFS path. We will look at how to install TrueNAS on Proxmox below. sh script will always assume - Long story short, I want to run a high IOPS PostgreSQL dependent database in a Docker container inside a KVM VM on a ZFS filesystem consisting of NVME SSDs. Adding a zfs disk as SMB Share on a Proxmox host February 2, 2024. I think where you’re running into issues is that you’re trying to apply a modern cloud paradigm to 20 year old VM paradigms. Need help accessing ZFS pool in Proxmox for new virtual machines You do, yes. e. If your hardware burned but you had a backup of your VMs and containers - all you need is install Proxmox again and restore those containers. Note that since Proxmox 4 uses systemd, /etc/defaults/docker is ignored. Disk Speed Benchmarks As of ZFS 2. Also docker can't start in LXC on ZFS datasets: 1) overlay can't work on ZFS 2) docker ZFS storage driver can't manage ZFS inside LXC But can use ZFS volume (without Proxmox UI, editing lxc-container configuration directly) with ext4/xfs and with overlay. Maybe we get it with LXC-ZFS 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. 4, but obviously the ZFS has been setup under Proxmox 6. Proxmox - Docker/Portainer LXC and NFS access. Docker Container on ZFS (LXC)--> YESSSSS, finally every docker image works without issues!--> On zfs 2. 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. Best security case is in a VM. See Point 6 Currently, my proxmox node runs on a single SSD (ZFS). I mounted my SMB shares inside nextcloud to use my TrueNAS files. Create an LXC and install Jellyfin. I rebuilt them on a vm now and they work fine. Then docker (installed on host OS) for the rest of the apps. Could find those two articles on how to accomplish that with an unprivileged LXC but it Nope. Docker aims at running a single application in an isolated, self-contained environment. Now is one of my 3 proxmox clusters and all the apps see each other Proxmox 8. Choosing ''Directory'' type storage forces Proxmox to create . As far as the documentation of vfs goes, the driver is inferior to anything else with lower performance and uses more space, but is the only driver that works on any block based backend. Use this if you want: one unprivileged LXC container per one application (one docker-compose. container? /home - encrypted ZFS (key on /var partition) - where containers data, secrets,configs are stored - snapshots of subvolumes for each docker app But instead of manual scripting with snapshots and backups maybe i should just return to Proxmox? Ive used 4th and 5th version and the only problem was docker@lxc@zfs (VFS storage driver was crap). What settings should I choose for high performance? I have been using ZFS for a while and know the basics, but this setup confuses me. Reply reply If you mounted a part of your HDD-ZFS as a virtual disk to your LXCs and VMs, the backup job offered by Proxmox should backup data of both SSD and HDD. Run docker in a VM. This also enables me to run VMs or LXC in Proxmox instead of TrueNAS which I prefer. The steps should take under 1 minute. You'll probably need an intermediary for storing data for moving ext4 to ZFS. Skip down to the section on installing Docker to complete the installation. deb11. The Container is stored on the same disk where is running Proxmox (/var/lib/vz/), and this latter is using ext4 as well. CPU-limit = half the cores on the box, but cpu shares set to low to avoid killing other vms; container for mythtv - bind mounts for media For immediate help and problem solving, please join us at https://discourse. This should enable running Docker inside privileged LXCs. This is for dev only. Mirrored New to I ran an Ubuntu server VM in Proxmox as a NAS/Docker/Media server for a long time, when I first set it up I was using a combo of zfs, snapraid and mergerfs so TrueNAS didn't really make sense in my use case. Create an LXC, I have nothing against installing it in a VM but since i installed proxmox root on a big zfs pool that spans all my drives I can't create a VM because there are no hard drives to select when I believe this is not the recommended way to install docker on proxmox (for security reasons) I don't have sufficient knowledge to judge this on More insanely, I also ran Docker on the Proxmox OS directly for the first while, that was a poor idea from a security standpoint, IMO. I already have an Ubuntu 22. Proxmox with LXC containers and Hi, I just found out about this from troubleshooting a Nextcloud install. I think this is really the only difference that means anything to a home lab. The proxmox server has a mirror zfs pool (2x2TB) in which I'll host the VM files among other stuff. I migrated my Docker container installation from ZFS to Ceph (Ceph shows as ext4 in a container). The LXC container should not suffer from the Next step: Use Backup of original LXC (ZFS), restore to LVM and redeploy stack. A problem with encrypted ZFS volumes is that they need to be unlocked after each reboot. All i know is that when i installed you had to use the proxmox kernel because it has all the ZFS hooks compiled in. Feel free to create an issue to debug those. 1, 80% of docker images worked, but some like speedtest-tracker don't. I had Let’s Install Docker on Proxmox, with ZFS, and good performance! We are installing docker-ce on the host, and Portainer to help manage containers. Since the VM and LXC container ran on the ZFS pool, I edited the Docker config when testing on Proxmox to move the data-root to a dataset on the ZFS pool. efi is not identical to your \EFI\BOOT\BOOTX64. Used built in ZFS for file shares (NFS and SMB), LXC for firewall/router, and Pi-hole. I have two zpools on my machine and, though I'm still a bit undecided on this part, I think I'd like to run the guest OS / Docker on one zpool and Thank you for reporting back. On this pool I have a virtual disk which is the filesystem for TrueNAS, also using I remember some time ago proxmox kernel was recommended for ZFS plugin, but if I have fresh installation of OMV6 and don`t use ZFS at all, will proxmox kernel bring any more stability or something?

Docker, on the other hand, is much better at being managed by automation. I use syncthing on my devices for remote backup. This may mean that the package is missing, has been obsoleted, or is only available from Hi, we are evaluating ZFS for our Proxmox VE future installations over the currently used LVM. a dataset for docker services (Planning to setup a docker swarm) a dataset for multimedia for my home users (Movies,Musics,Photos) I already have a truenas server that run with ZFS should I keep proxmox on zfs or change to LVM Note Proxmox is still a fresh install I'm trying to understand the proper way to setup Docker on a Proxmox VM using ZFS storage. if running Root on ZFS) and configuring Docker so that the Docker data (i. 3 I ran a few storj docker containers in Proxmox alongside LXC containers and KVM VMs without any issues for years. Once you get it installed, docker startup will fail due to aufs (upstream docker bug imo) so shutdown lxc container, add additional storage mount point from your ZFS pool at /var/lib/docker (this is where your NC data will live), and upon restart, docker will correctly use ZFS driver on /var/lib/docker rather than the AUFS driver. Have had many issues with docker in LXC breaking for no apparent reason (even restoring from backup had no result). 13, 2023), overlayfs is supported on top of a zfs filesystem:. CAP file to a USB drive Install Docker on Proxmox. So then it falls back to a must slower storage driver that isn't intended for normal usage. 0 (Oct. Proxmox host can run ZFS and have the benefits of that, but the NFS VM doesn't care and use basic Ext4 formatting on both it's virtual disks. 2. I had previously been able to get docker running in unprivileged LXC I personally run my all my docker containers on proxmox directly. 2 (or newer) no workarounds are needed. I think. I want to continue to use Docker - I have heard that the r/w performance of Docker inside LXC may be significantly reduced with ZFS as the underlying fs, with some rather complicated workarounds available (officially, docker supports both BTRFS and ZFS filesystems). EFI, it's definately not \EFI\systemd\systemd-bootx64. This is normally transparent for the OS in the cont If your backend storage is zfs, 90% of docker containers will work, 10% not. Proxmox I still kept one container on one of my nodes to host docker for any service that does not require external permissions to the LXC or storage (e. Quoted from the Documentation: "If you want to run application containers, for example, Docker images, Converted my ZFS to Ceph and docker no longer required special handling and now just Hi, I'm wondering which Docker strategy (home server) is best. My FreeNAS zvol is RAIDZ2 of 5 spinning disks (WD Red 3TB). Install Docker Kubernetes relies on a container runtime like Docker to run its workloads. Once you have configured the iGPU for passthrough, you'll make sure it's actually available in your VM and working with drivers. 64GB of RAM but Proxmox is hosting a 2TB zfs datapool so it uses at least 32GB for that. If you chose the secure option of requiring a passphrase, the encrypted ZFS volume won’t be mounted until after you SSH into the machine, run the zfs mount command, and type in the passphrase. Hostname: the hostname of the container . zfs/snapshots directory for smb shadowcopies). I did port a windows vm from VMware to KVM and it was fine for as long as I needed it. I created ZFS datasets on the proxmox host using the built-in ZFS integration in proxmox. There might be somesthing strange with docker and ZFS. TrueNAS (Scale) obviously does ZFS natively, has KVM if you want VMs, as has the TrueCharts. [1] (Unprivileged LXC is a different beast, let's keep this thread For immediate help and problem solving, please join us at https://discourse. There was this issue with docker that used a very slow driver if ran inside LXC with ZFS. I recently moved everything to a different server on 7. 2-amd64 ) kernel and forget about it?! The source code of Proxmox VE is licensed under the GNU AGPLv3 and free to download and use. Docker containers would start really slowly and I'd get random file errors. behind an Nginx reverse proxy and using a common ZFS storage pool, would you recommend an Ubuntu Server with Docker containers or Proxmox with LXC containers or a combination of both (i. 1 uses ZFS 2. The LXC logical drive will fill up very fast with very slow Learn how to set up Docker in Proxmox using an LXC Container or Virtual Machine! Configure Containers directly inside your Proxmox hypervisor! After experiencing a nasty 'gotcha' moment when deploying Nextcloud AIO on an LXC host on my PVE server with ZFS storage (TLDR; Docker apparently then uses the 'VFS' storage driver I recently migrated my containers to a new proxmox installation with ZFS instead of LVM as the backbone, where I encountered the issue starting docker in containers with ZFS. Exactly. I give 1 nic for truenas file shares and 1 nic for proxmox access. Proxmox does ZFS if you really want ZFS, but as you pointed out, Proxmox storage ismeh. While I found guides like Tutorial: Running docker in LXC is advised against by the proxmox developers. It all worked fine, just had For immediate help and problem solving, please join us at https://discourse. I'll start by saying what I have already. Let’s Install Docker on Proxmox, with ZFS, and good performance! We are installing docker-ce on the host, and Portainer to help manage containers. Agree. 04 LXC Unprivileged container. Docker On VM -> Easy and recommended. Is it better to run one LXC with Docker and all containers or a separate LXC with Docker for each container? Should I use ZFS with mirror disks on each node and replicate data across all other nodes to achieve HA or Install CEPH on all nodes and combine 6 M. You could also run docker directly on bare-metal Proxmox debian, but that is a bad idea. UPDATE: I’ve abandoned this setup. Especially since docker won't be an issue anymore on lxc containers with openzfs. Providing several LXCs access to one local ZFS store - Jellyfin Hello, I have a proxmox server in which I intend to set-up a Debian 12 VM in which to install Docker. After you’ve determined which OS you’d like to use, download the latest version of TrueNAS Core or TrueNAS Scale. ZFS looks very promising with a lot of features, but we have doubts about the performance; our servers contains vm with various databases and we need to have good performances to provide a fluid frontend experience. For what it's worth, I've been running Docker on the Proxmox host directly for many years without issue. Any downsides with my suggestion? Docker/Docker Compose on bare metal in Electric Eel !!!!! The overlay storage driver detects the file system is ZFS and refuses to run, then the ZFS storage driver detects it doesn't have full access to the ZFS pool and refuses to run. 04 template. Using ZFS as root filesystem doesn't mean you'd have to use ZFS for /var/lib/docker too. If I convert my LXC ext4 file system to ZFS then will I able to take Snapshot? Docker should detect ZFS and automatically use the ZFS storage driver. 2 which finally supports overlay2 out of the box. I build everything as mirror/Raid10 ZFS pools. Proxmox also has some other benefits like quick and guaranteed sandboxing for running suspect software, docker on the other hand is not completely compartmentalized, it is possible for a program to reach out of a container so to speak, so with docker you dont really have the guarantee that each container is isolated from the rest. This way I get the cute/easy TrueNAS GUI, S3 backups, ZFS snapshots, Rsync module syncs, etc while still having the datasets available at the Proxmox level. Zamba is the fusion of ZFS and Samba (standalone, active directory dc or active directory member), preconfigured to access ZFS snapshots by No experience with Proxmox, but have experience with ESXi -> Ubuntu -> Docker -> HW Transcode. 3rd and final: I run zfs locally on my proxmox host but smb via a turnkeylinux container setup for file hosting, with a mount past through to it. If you install Docker CE as normal, and Proxmox VE was setup with the installation on a ZFS rpool, then the system will fail to boot if you make a container using default settings. Docker on Server Node -> Should be no go. Although Proxmox provides built-in support for LXC containerization, it's possible to run Docker containers on the virtualization platform To use docker on zfs pools i created zfs volumes manually, formated it to nonzfs filesystem (i chose xfs because of later flexibility in resizing) There is only one host that runs Proxmox. doesn’t works . 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. raw file and mount it inside container using loop block device with ext4 filesystem.

Feb 21, 2015 Since I use ZFS the LXC disks simply are datasets (with all their benefits). Trying to get anything to run on docker on this setup is beyond my capability or patience to figure out. 2. Or something you could try is using NFS shared storage across all Proxmox hosts and then doing the same thing of setting a NFS mount in each lxc. Do you know if the "standard" Ubuntu Server works? LnxBil Distinguished Member. I don't see why this should be preferred over the real ZFS driver for Docker, which is CoW-based, super fast, has quota and snapshot support (for Do you use Docker's ZFS driver with this setup inside the VM, A Openwrt VM as a router No ZFS at all And a Proxmox backup server in an arm VM in another system (a Freebox Delta which permits to install 2 VMs at least the other VM is a small distrib for apt-dater all the others) Is there any guest OS which run Docker without any issue on Proxmox with ZFS? I used Ubuntu cloud image with a generic Kernel. Several VMs are eating 8GB each, leaving about 14Gb for the Kubernetes I. ZFS as a plugin, support could easily stop (it almost didn't get updated for OMV6) or an update could break it. I am on Proxmox 8. I now have a 3 node proxmox cluster with ceph up and running. Here it can store its vm-drives and use all the cool zfs features (like mentioned above) + also use trim/discard to mark blocks in the middle as free. 0 Release. My workaround for this is create LXC storage on Proxmox's ''Directory'' type storage. 0. Note: This is a crosspost. For my ZFS configuration I chose to use mirror vdev’s, for it allows upgrading storage two disks at a time, but it comes at a cost of 50% space utilization, and protection against only 1 drive failure. Also the guy who releases the OMV-Extras, including the ZFS addon, uses the proxmox kernel. Proxmox Virtual Environment.

Hi, I'm running Proxmox 7. I also never updated proxmox. com with the ZFS community as well. As far as I know, I don't plan to use ZFS on my main ssd (on which proxmox is installed), so it's between XFS and EXT4 for my use case. 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. You can run the containers with specific rights and I "orchestrate" it all with docker compose. It's really annoying as with LXC we can have a much smaller overhead (especially RAM usage) and being Unprivileged by default, The NC data directory is on a separate encrypted ZFS dataset on the Proxmox host and bind mounted into the container. Since I'm using Proxmox, I tend to avoid using docker just because "deploying shit is easier" because that would be having software running inside a container running inside a countainer and it mentally hurts me. I set nextcloud up in a LXC Container but you might also look into using a docker Container instead. The beauty of lxc is that it basically runs the same way a docker image does (docker is based on lxc, after all), but the style of management is more like a vm. gz> Source VM to convert to CT (Eg Bare metal Truenas with 1 vm running proxmox is "the way". For this I restored a snapshot to ZFS storage. 3 using zfs and now every time the server power cycles, every docker container in lxc breaks. I'm excited about the 8. 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.

Nothing wrong with Docker on Proxmox, I do it. 10 with docker versus proxmox with truenas vm and disk to proxmox and will try messing with a file server setup using lxc or vm as a replacement for truenas fronting zfs pools instead of disks, but that will need some solutions for share setup 3. Since it runs in Docker officially supports ZFS (on Ubuntu) but creates lots of datasets in the process. Unlike overlayfs, fuse-overlayfs can So here's the setup in a nutshell: two nodes: node1, node2 in a cluster cluster is healthy and running the latest version of PVE, all updates applied node1 storages: local, local-zfs, pool1 node2 storages: local, local-zfs, pool2 The question is: how do I ran Proxmox for host OS. for ZFS it detects that FS is ZFS but cannot use all magic features due to permissions (unprivileged LXC). I'd like to have separate datasets per application with Docker too (e. I'm using Proxmox 7. Worst is on the host OS. Thus running it without Docker as virtualization layer.

OMV6 - install ZFS, Portainer, Docker . Yes use proxmox containers for your plex, sonarr, whatever stuff. I have different LXC's on Proxmox (paperlss, haimdall, zoraxy, iobroker, ). Then, Proxmox is using a standard ext4 virtio disk on a zfs pool, so it's safe, easy to backup, replicate and snapshot, invisibly to proxmox. g. Now I want to have a huge media library but I need a bunch of docker's to access it. Starting with Proxmox VE 8. Resource Pool: a logical group of containers and VMs . Installing Kubernetes on the Proxmox Cluster. ZFS caveats: poor performance with Docker-LXC nesting This is an unofficial compilation of Proxmox Backup Server to run it in a container for AMD64 and ARM64. How to Install TrueNAS on Proxmox. 2nd attempt I setup a zfs pool and stored the files locally on the proxmox host, shared via SMB and local mounts within all my docker containers. Old info: If you're deploying Nextcloud AIO (or probably any other resource intensive Dockerized app) on Proxmox + LXC and your storage is ZFS, you'll soon find that: I would now try to move the disk to the ZFS system. Note: If you are running Podman on BTRFS, there is also additional configuration that needs to 4. efi that would Here are some steps to consider when migrating Docker containers to Proxmox: Familiarize yourself with Proxmox and its features, including how to create and manage virtual machines and containers. Need: Docker to handle the media stuff and some other small processes (DNS, Unifi, etc) Need snapshots on-box for virtuals and files, and need backups off-box I read that ZFS is awesome and I should have it. proxmox boots from zfs-mirrored 500G drives (12) drives in RaidZ3, 2 enterprise SSD for slog/l2arc; container for plex - bind mounts for media. If I move all unRAID Docker/VM’s directly into Proxmox the only thing unRAID really offers that Proxmox might not is my ability to use /mnt/user/ which has both Cache drive and Array drives. At the moment, my LXC container is running Debian 10 on ext4 file system. Determine if you’d like to use TrueNAS Core or TrueNAS Scale. Since it runs in a container, it is by I am about to switch from docker (lots of compose files) to docker swarm. SSH Public Key: a public key for connecting to the root account over SSH Even with Nesting and keyctl on, I cannot seem to get Docker in LXC to properly register ports to use. If you are running ZFS on your Proxmox installation like I am, read the configuration section below. the container's config and data volumes) are stored on a separate ZFS pool with a dataset pr. That is the compromise that you make using that method - you ensure complete kernal isolation at the cost of system resources. Now backing up everything is easy using a Proxmox Backup Server. I don't like it even if I don't really have solid arguments about that. I need to change the underlying storage for a Proxmox LXC Debian Buster container from RAW to ZFS. 0-2. After the download finishes, navigate to Proxmox, then upload the local-zfs (type: zfspool*) for block-devices which points to rpool/data in the ZFS dataset tree (see above). Password: the root password of the container . For persistent storage of Docker containers, I have a separate FreeNAS box sharing out NFS and iSCSI target. Installation of fuse-overlayfs fuse-overlayfs is a similar to overlayfs runs in userspace and can be used without root permissions1. local-zfs, local-lvm, etc) --source <hostname> | <file: *. 04) I don't have write permissions. What is the difference between using the Docker ZFS storage driver (from that I understand Docker will default to this driver if the underlying filesystem on which Docker is installed is ZFS, e. yml application using Docker Compose inside an unprivileged LXC container, on Proxmox Virtual Environment (PVE). The only VM is an Ubuntu Docker host with 15-20 Docker containers. This also ensures the storage pools are up before any VM's try to boot. I installed all LXCs and VMs on a SSD, data is stored on a ZFS volume (HDD RAID 1). Docker will default to using ZFS as the storage driver and the system will not boot properly after you make a container. kicou. to rollback individual applications to a previous snapshot or to use . 1 / ZFS 2. I use portainer with docker and it has been a breeze (docker also runs in a LXC with nesting enabled). Question This is probably gonna be a fairly simple thing for someone who knows what they are taking about. According to docker, "The vfs storage driver is intended for testing purposes, and for situations where no copy-on-write filesystem can be used. Docker on LXC -> Oh Boy you will save lot of resources. We’re installing Docker along with Docker Compose from the official Docker repository according to the docs: Update: If you create and manage a ZFS pool in Proxmox, then the pool can be mounted, using Bind Mount Points, in multiple LXC containers. Since it's almost a full fledged ubuntu/debian based container If it crashed or broke or failed you can just roll back. I have my nextcloud on Portainer/Docker and deciding on the right way to attach/mount the whole zpool. I have all my docker configs stored on a zfs volume and I backup them up using duplicati. How this might look is you have your zpool, with a dataset calld vms , and you amke a new virtual hard disk HA. On the container, I enabled the nesting and keyctl features right after created using the Ubuntu 20. Is that a possible approach, or can I change something in my Docker/ZFS/Proxmox configuration? Here are a few more links: podman-on-lxc-with-zfs-backed-volume-and-overlay; podman-in-lxc-what-do-overlay-not-support-file-handles; probleme-mit-lxc-oder-vm-bei-speicherung-auf-zfs-storage I need a little help to figure out how to mount my zfs pool to a container. I have already been through that link and mounting regular directories works great, I use docker in an LXC that runs on a ZFS pool. *NOTE: "zfs-dataset" would be the more accurate term here. was an oversight on my behalf since containerisation in most selfhosted / homelab contexts where I was referred to Proxmox from, refer to Docker. Convert your Promox VM to a Container easily with docker support and some extra sweetness for DietPi VMs (zero calories tho!) - thushan file> --target <name> [options] Options: --storage <name> Name of the Proxmox Storage container (Eg. This is why the ZFS storage driver is used. Installing Proxmox Preparation. Just installed docker, portainer and it ran just fine. # on the Proxmox host system drwxr-xr-x 5 root root 5 Apr 13 15:55 pve # Inside the pve-directory (Proxmox host): drwxr-xr-x 2 root root 0 Apr 13 16:49 mediashare-config Is there a way to get this permission issue solved without turning the LXC into a privileged container (which would create problems with docker). 0 Wheezy / Proxmox 3. xxx. Question - not resolved I just built a new NAS box with the following components; I3 10100, Gigabyte B560I Aorus Pro Ax ITX board, Boot Samsung 256gb NVME, 750W phantecs PSU (second hand), 3x3tb Seagate drives (pulled from existing server) Nextcloud on Docker on VM on Proxmox Scripts and notes for running one docker-compose. 4x 10TB exos drives in raid-z1. If you are resource constraint, use an alpine vm. Linux is typically pretty low overhead as it is, so the additional resources you use having one VM running Docker doesn't bother me. Hi, this post is part a solution and part of question to developers/community. And I can backup the Proxmox cluster VMs to the NFS share, even TrueNAS itself. Any update on the proxmox system can change how docker in LXC behaves. Reply reply thelittlewhite I recently migrated my containers to a new proxmox installation with ZFS instead of LVM as the backbone, where I encountered the issue starting docker in containers with ZFS. It's done pretty well so far, but ymmv. Hi all, Just migrate my old Proxmox 6. io Reading package lists Done Building dependency tree Reading state information Done Package docker-ce is not available, but is referred to by another package. In ESXi you can configure PCI devices for passthrough, assuming Proxmox has similar features. Setting DOCKER_OPTS there is ineffective. Disable swap Edit the configuration file, typically located at the following file: /etc/fstab The only hitch was Docker, because, as it turned out, Docker didn't like being installed in a ZFS-based LXC. Never had an issue. See, you really have to have a deep understanding of all the systems involved to understand what sort of risks you’re opening up yourself to by going off script. Now on my homeserver, I have secondary NVME disk (A) for VM install and a 50TB RaidZ1 ZFS pool with 6 drives in my proxmox host (beside OS disk and ISO storage). Hello, I am trying to mount a zfs pool in a LXC container. 04 VM running docker (so far only a portainer container) on that Proxmox system. We think our community is one of the best thanks to people like you! Proxmox VM Start: Wait for Encrypted ZFS Volume Mount After Boot. 0 : proxmox-ve_8. I use ZFS for everything except for one important Proxmox use-case: running Docker in unprivileged containers As far as I've found, the only way to provide near native speeds for local filesystem access for Docker containers is to run it in an LXC. I managed to get it mounted using : pct set vmID -mp0 /poolname/,mp=/mountName after this I had to fix some permission isues wich I managed to to by doing some group mapping like in this example /etc/subgid root:1000:1 After much anticipation, Docker is now set up to use ZFS with the overlay2 storage driver within an LXC container. In this case I use a Ubuntu 18. Zamba LXC Toolbox a script collection to setup LXC containers on Proxmox + ZFS. x to the new version 8. This is an unofficial compilation of Proxmox Backup Server to run it in a container for AMD64 and ARM64. "It appears to boot with GRUB in UEFI mode, which is normal if your root filesystem (Proxmox installation) is not on ZFS. Everything can be controlled over the network using the Proxmox VE API. It should be worth mentioning as well, that after setting up this ZFS pool I started seeing high memory usage on my node. I would like have some fresh opinions on this topic, especially after Proxmox VE 8. Sharing directories with LXC uses bind mounts, which are highly efficient. Make sure your Proxmox host has enough resources (e. I understand Posts #15 to #19 are pointing in that direction as well, allthough Docker says the issue is fixed. Yes I know Proxmox and TrueNAS are very different on their design. Proxmox officially recommends running Docker inside VMs. I even managed to corrupt my pool in the process. ofywj lxmjr nzel ohudmfre hduzyazc sciwh xqra wxra cmwk jsox
