Run Docker in a Proxmox LXC Container #shorts #docker #proxmox

Please also tell about the Security Issues that this creates! If you "take" the Docker container, you "take" the Proxmox host. That doesn't happen in a VM.

I'm doing the same on Proxmox VE. LXC helps with network setup (a dedicated public IP per LXC container) and docker helps deploy the applications.

I got confused a bit - I guess it deserves a bit longer video.

AWESOME TIP.
Pls make another video - I need to run Oracle Express Database (to test query optimization of office work) in Proxmox.

[wjffhfgj]

personaly I use a VM with alpine Linux to take lower ressources through vagrant and then I install Docker

[rvanwaay]

I installed docker on the proxmox host, but maybe I'd better do this approach

[arghyl]

I'm going to try this RIGHT NOW!!!

[rachidyekini]

Good stuff as usual, thanks Marc.
Not sure but I think I have read somewhere that proxmox makes SSD life shorter if installed on it, I hope you could explain this in one of your next videos. Cheers

Hi Marc, and thank you for the tip. i'm using your option 1, privileged container so i am wondering what additional risks there may be if i was running in a production environment (i'm not, it's just my own learning home lab...but if i were.... ?). i also went for the turnkey core container, because it was right there in the templates, ready to deploy and i figured it would make for a lightweight host in which to run docker containers.

Marc, I'm trying to learn Linux creating a media server at my home. I'm looking to setup Proxmox and have two server distros installed in containers(one as a backup incase something happen with the main one). I was wondering if I should use Docker, is this a bit advanced to my use case?

[MaxBauer]

Hi @OneMarcFifty Is it possible to use Fedora CoreOS instead of Debian for the LXC-Container?

[dominick]

Can't that lead to some kernel issues? Making it privileged can have it change the kernel and bork the proxmox install?

[Felix-vehs]

Just keep in mind that if your Proxmox VE Host uses zfs, you might run into problems with some docker containers (vfs etc.)

[yboujraf]

Dear,
Then to host docker in LXC container is to enable keyctl, nesting AND to keep unpriviliged. Is it right?

[HyuLilium]

Why does keyctl need to be enabled? I have docker running on LXC without keyctl

[Currysuechtig]

Just don't do that. VM's are just so much better for isolation, backup and migration. And if you are creating the Docker LXC-Container on a ZFS filesystem, you have to create a ext4-Disk on top of that for /var/lib/docker as a workaround.
Best practice is to not even create a single LXC container and just rely on VM's and Docker-containers.

Or go down the Kubernetes rabbit hole 🐇🕳️🥰

[giorgos-cfrv]

NO lxc containers are NOT ment for docker the brake all the time. Please don't

[redetermine]

this is unsupported, i found out the hard way once.

[pojomcbooty]

I liked proxmox but one day it just failed on me and was a pain to fix so I switched to ESXi and never looked back
