Hey! I just did this over weeks and it was pretty fun! I transformed almost all my docker containers to lxc containers, except authentik and wyze bridge, which i couldn't because they don't support it. i have all of my homelab containers with one openwrt, and public ones on an other. It works great!

[@ISBayHudson]

FYI docker runs fine in an LXC container with nesting enabled. When docker is the most.sensible way, I set up docker on the LXC

[@KeithHardy-y1p]

Thanks!

[@H0mework]

Best of luck to you! You've been super helpful you shouldn't be going though this.

[@ewenchan1239]

LXC containers are VERY powerful. A LOT of people/tech KZbinrs talk about homelabbing with VMs, but I think that some of the real magic happens with LXC containers instead. It's significantly lighter weight and faster than a VM (since it shares the kernel with the host) and I've been able to actually get a LOT done with LXC containers, pack more stuff in with the same hardware without having to carve out/provision hardware resources for VMs. The only time that LXC containers doesn't work is if I want to run a different kernel (e.g. Windows, Solaris, macOS), for all of the Linux stuff, I think that I am down to only two VMs left (because it's much more difficult to get multi-monitor support with LXC containers than it is with Linux VMs). Mount points are awesome. I use it all the time.

[@itznolimitz]

Nice, found your channel thru hardware haven. So sorry about your prognosis, hope things get better for you. I've been moving all my services to my proxmox environment also, this video helped me thanks!

[@mikekane9734]

[@donaldhoudek2889]

{Superhouse #23 - Preparing your home automation for death}. There is an excellent KZbin video by SuperhouseTV, regarding preparing your home automation for your absence, as well as mine. It sucks when you have to talk about this. I am in a similar situation, but different and the wife is no where near being able to maintain our home automation. I started documenting my network, sensors, security.... a few years ago, but still have a long way to go. I started with an overview and then went into detail. One problem is that it is a "Living Document" and will never be completed. I do have a son that is good at this stuff so I am in the process of giving him remote access and full control of the entire system. I am 75 and time is running out, so I am spending as much time on this project as possible. Best of luck to you!

Nasty NAS. Nasty backup, simple sweet and stupidly hilarious I love it

[@geesharp6637]

Oh wow. I didn't know about data center storage. I was going to do this manually. Life saver.

[@Zedris]

one of the best channels on youtbe

[@ronm6585]

Thanks Don.

[@MarkConstable]

Heh, an almost docker free homelab. Love it! What would be interesting is to compare resource usage between the previous docker containers and after moving them to LXC. Each LXC requires an entire OS, albeit a lightweight Debian one, but then Docker has all these layers that pull in an unknown amount of... dare I say, garbage. As you say, the LXC version "feels" snappier. Comparison stats on cpu, ram and storage usage between the two would be fascinating.

[@bluesquadron593]

These lxc containers are docker containers with a single application installed.

[@GreatTaiwan]

why is docker (let's say container) free a good thing ?

[@andreas.grundler]

@@GreatTaiwan Docker containers may contain old versions of libraries or programs that have security vulnerabilities. Unless you build the Docker container yourself, there is nothing you can do about it. With LXC containers, on the other hand, you can install security updates.

[@MarkConstable]

@@GreatTaiwan I simply do not want to deal with or use Docker technology. I think it's a dumb and needlessly complex concept compared to LXC containers.

[@MarkConstable]

@@bluesquadron593 Sure, but LXC containers have a "real" OS as a foundation instead of a mess of overlays. The option is there to include more traditional services if needed, with a single unit for backup.

[@fedefede843]

I've seen this migration a 1000 times. It is good. I understand the fine granularity to backup the entire container. That is great. I also see the resource management being more efficient in some cases, that is a plus too. Sharing host HW, another plus. Etc. But... How about apps life cycle ? Nobody seems to address this. In my docker setup I use watchtower for all the automatic ones. For the critical ones I click by hand using portainer. There are several approaches to this, but all are concentrated in that one docker service. What now? How do these individual 20 LXC containers update? Who controls that ? Is there any visibility? I would really appreciate if someone made a video touching on that. Thanks for sharing!

[@atetraxx]

i would think you could write a script for that. ssh into your proxmox node and run the script in terminal. I've only ever had 3 lxc's running at once so always just updated manually

[@mehedyamin]

Wishing you the best! 🙏

[@accordxtc319]

I wish I came to your channel under better news, be strong and sorry I'm late to the channel. Really enjoying the content, thank you

[@nitramdmij]

Thanks, Don! Stay strong!

[@altaresification]

Extremely clever, you've convinced me to migrate too. Take it easy Don!

[@somegeek7126]

That's why I like using compose files. You can use a compose file to create a stack in portainer, so one method does not exclude the other. Having all your appdata files in the same location is a good thing, it allows you to easily retrieve the config of your containers using scp.

[@davidlakes5087]

LXC containers in privileged mode are just a huge security hole. Anything that can’t run as unprivileged LXC should instead be run in a VM. I wish you the best!

[@karloa7194]

I'm in a process of moving away from containers. I went with VMs because of NFS. I didn't mount the NFS via Porxmox because the host has read/write access to the share.

[@TheBupsta]

Gotta feed that algo! Also, this is great content!

Thank You your videos so simple and concentrated at a same point. Easy to folow. And always with a so good wibe

we ❤ you don, keep fighting. also this is very useful since ive neen struggling to create a linux vm with igpu passthrough on proxmox so im going to be giving lxc containers

[@johncnorris]

Looks promising!

[@jgz2]

Thanks again. How does one attach 2-3 12TB drives. There doesn't seem to be the normal SATA connectors on the MS-01. Do you use a DAS? NAS? Confused where the data (ie. movies and tv shows) for sonarr, radarr, jellyfin etc would go.

[@NovaspiritTech]

once i clean up my network a bit more i will make a video about, but for now i have a proxmox server and a NAS or at least i hope the end result will be

[@RenpySage]

Get well soon Don

[@rotu41]

Thanks Don. More LXC goodness. I'm running a win 11 LXC but encountered some weird issues regarding graphics drivers and mounting volumes.

[@laptoplivegaming]

Great video Don!! Keep it up

[@MarkConstable]

Another thing that I do is I have a couple of Proxmox Backup Server hosts (actually all my PVE hosts are also PBS hosts) with an auto 6 hour backup schedule, so I can freely delete most of my only lightly used VMs and CTs and then restore them on an as needed basis. Ie; if you don't use your Win11 VM all that often, then you can "put it on ice" and restore when needed.

[@NovaspiritTech]

yup i have so many things on ice, like you said

[@yot3605]

Get well soon Don, god bless you

[@traxeonic3600]

Strength and best wishes. Appreciate the video content too.

[@heaton922]

Thanks Don, god bless you

[@owNewBlood]

awesome content, always great to how you get your tools workin

[@donkey3077]

The reason I've stuck with docker containers is that they are easier to keep updated. A LXC container needs to be updated in at least in two ways, you need to update the OS and then you need to update the app (and whatever tools the app uses, like apache, some runtime). In docker I just do docker compose pull to download latest image. Or am I doing it wrong?

[@RomanTruman]

I also think so. I'm using watchtower container to keep everything updated automatically.

[@Elkan1976]

The container is not developed to be updated every week. If You plan to update, You must test before. When you use containers just think "If works, don't touch it" 😅

[@cgaquikkie]

BTW for next time: privileged LXCs can just used NFS/CIFS directly, unprivileged LXCs require the use of bind mounts. You selected privileged LXC and then went through the bother of bind mounts instead of just modifying /etc/fstab.

[@bluesquadron593]

I don't think you need privileged lxc for mounting. Also, probably want to turn off the replication for the mount point. Also check how to backup an lxc with mount point. I believe snapshot doesn't work.

[@JohnPMiller]

If anyone has a company that would be interested in sponsoring a Novaspirit Tech video, it would be an effective way to reach Don's devoted viewers & subscribers. Always great content from a great guy!

[@paullacatus8975]

Thank you Don !

[@itznolimitz]

Wanted to comment on mountpoints in containers if you have a cluster setup. I have a proxmox 3 node cluster using ZFS replication (not ceph) I had issues with creating a replication because of the bind mountpoint, to resolve this you need to set replicate=0 in the mointpoint. That resolved the replication issue, however next I couldn't migrate the container to other nodes. to do that you need to set the shared=1 in the mountpoint. Mark sure the mountpoints exist on all nodes exactly the same (they should since it's set at the datacenter level). the mountpoint now looks more like this: /mnt/pve/nas/movies,mp=/movies,replicate=0,shared=1

[@luisalcarazleal]

Thanks for the content. I really wanted to this but I'm worried about those "Stale file handle" in both NFS and CIFS mounts. I have a script that automatically unmounts and mounts them on my VM but even that isn't foolproof that I had to do a restart.

Do you use that openwrt in lxc as just local firewall for that server or you're using it as main router?
