[@benlayash8882]

You are a star ,simple and precise . well done

[@mrdhksan]

Excellent! Supe clear! Not annoying !

[@GutsyGibbon]

Great. The video was worth its weight in gold right at the beginning. I am just starting with Proxmox and I assumed the containers were ephemeral like other (Docker) containers. This makes things much easier for a web server or LAMP server where content and database live on after stop and restart. (If I understood you correctly.) Thanks!

[@jeffrisdon2803]

Hi Ive been watching your videos on Proxmox and linux. Very Helpful! Thank You!

[@bearvsshaan]

this is incredible, you're a fantastic teacher!

[@SuijoART]

I very appreciate your Proxmox serie thanks again. It's a great work. Do you plan to show how to configure the network cards of a VM with the CLI ?

[@jSirBrickzAlot]

This is a great series Jay. I decided to get my son's old Dell Latitude 3500, which has a 256 FGB SSD, 8 gb of ram. Still managed to follow along so far, have the 2 Ubunto web servers running, 1 windows 10 vm with 4 gb ram, and now a containter. All running on this laptop. Also RDP'd to the windows machine while typing this. Think I'll pick up a mini pc to add . Eventually a small 2 disk nas. Living in a Condo space is a premium.

[@udayarpandey3937]

Thank you :)

[@Datalore74]

Great vid.

[@mguven]

great videos, could you make a video for mounting points to explain sharing data between containers?

[@TuhkahYT]

Make sure nesting is enabled if you use a modern distro with systemd

[@danieldewindt3919]

grate demo

[@apulacheyt]

Great episode Jay as always. Any chance to explore PCI pass through on LXC?. I think it will be very interesting to use LXC for running Deep Learning workloads with an Nvidia GPU, if it's possible. Thanks in advance.

[@lundingantweni997]

Great series came just in time for my new build!!!

[@camaycama7479]

awesome

[@ricksmith219]

I have been waiting for a series like this, thank you so much... I am following along as they are released. I got the ubuntu container going as you did. None of the debian container templates seem to boot? Is there something special to get those going? I did them as I did the ubuntu

[@giancarlosrm]

Excellent content!! do you have any tutorial for add extra video card for the VMs. ?

[@mattgeo5039]

Will be nice know bit more about your server/hardware/networking setup if possible.

[@remedyreport]

I've been using proxmox containers in production for web servers since about 2016. I really love them. It allows me to make the most use of my Hardware. I run about containers simultaneously. One container runs ha proxy which manages SSL certificates for all the hosts behind it. I really want to find a template for a container that runs nginx with WordPress on it. This is essential in my opinion. Apache is too wasteful with interrupt requests.

[@nemac23]

How many simultaneously? Why not use nginx as load balancer? I see nginx and wordpress containers at turnkey

[@majorgear1021]

Question on container storage. if the machine I'm virtualizing is currently needs 150gb storage, do I make the rootfs drive that size? Or do I keep that one small, around 8gb as in your example, and add another drive? I ask because I noticed the "add" button under "disks" in the create ct setup wizard. Thanks!

[@rohedam]

Love the laptop arm in the background. Which one is it?

[@frankbaron1608]

is it possible to add a passthrough drive to a container? i can do it on a vm but i'd like to do it on a container.

[@TheOnlyEpsilonAlpha]

So Containers are stateful on Proxmox? I didn't knew that :O

[@jacksonpfeffer8159]

I'm super late to this party, so maybe it used to be different... but people should know that root access via SSH is NOT disabled by default (at least not with the proxmox ubuntu-22.04-standard CT Template). I think what jay meant to say is root SSH PASSWORD LOGIN is disabled by default. However, if you added your public key in the CT configuration, you WILL be able to login to the root user via SSH using that key

[@NhatLinhNguyen-ru5lf]

I have a noob questions: what does it mean by loading SSH public key when creating the container? Is it SSH public key of the remote machine that you are using to access the Proxmox / VMs. What is the function of loading it here? Will you be able to SSH into cointainer without password if you load SSH now?

[@ierosgr]

Wouldnt it be useful to issue the command pveam update. in order for the list of containers to be wider and more updated?

[@jameswhite1910]

It is updated daily by default.

[@paulmacgiollacaoine8619]

Can I use Docker containers on Proxmox? If so how and if not why not? Thanks for the great content :)

[@majorgear1021]

Yep. you can use them inside of a VM, and I think you can also use them inside of lxc's.

[@andrescalapt_]

Eyy pressed like button and the subscribe button! This is awesome! I'm wondering how can I create a VM with home assistant and a CT with Maria DB, is this possible? How? Thaankks

[@edwarddonnelly2937]

I've watched up to this one and cannot see anything about setting up extra drives for storage of VMs & containers.

[@ourkid2000]

Tried this today. Spun up the container and tried to SSH into it from another machine but I get port 22: Connection refused. It will ping the address but not connect via SSH

[@teberon]

Interestingly I can't even log into root using the container console. I need to use the proxmox server shell and use pct enter to be able to create a new user

[@LearnLinuxTV]

Did you set a password during the creation process of the container? I hate to ask that, because I'm sure you probably did, but I haven't experienced that before.

[@teberon]

@@LearnLinuxTV Yes, I did. Just did the test again. Might be something with the Proxmox host as I had also issues using Cloud-Init the other day. I think backing up the VMs and re-installing Proxmox might be a good idea

[@MichaelDirks]

@@teberon I'm having the same issue. Created the password during container creation. Tried to log on using root and getting Login incorrect. I have proxmox v7.1-7

[@justincollins4332]

@@MichaelDirks same here. I've tried recreating the container 4 or 5 times now. Same exact problem.

[@papperme]

Thanks for the great contents. I learn something new. I want to install windows 10 on proxmox. How can this be done the best way,?

[@jensodotnet]

vm

[@LearnLinuxTV]

When I get caught up, I'm going to create a stand-alone video on running Windows in Proxmox.

[@icanthelplt9061]

Loving this series, building my first home server with spare parts. 10700/64gb ddr4/2x1tb 980 nvme/5x4tb x300 drives. i also have two 500gb ssds not sure if i will use them or how i should exactly setup the install. i am going to be hosting multiple game servers using linuxgsm as well as backups and file storage with freenas. I am thinking vm for freenas, and ct for game servers. any advice would be great!

[@LearnLinuxTV]

I can see where you're going with the containers/vm, but unfortunately I haven't used linuxgsm before so I don't know how helpful I can be there - but either way, that sounds like a very fun project!

[@averagedev7768]

Nice spare parts. What is your main rig then

[@UniqueTech2012]

Hello Sir, I am looking for a help, LXC CT is not working with centos 7 template, even not starting the OS. Getting warning messages bellow... WARN: old systemd (< v232) detected, container won't run in a pure cgroupv2 environment! Please see documentation -> container -> cgroup version. TASK WARNINGS: 1 Thanks

[@aaronperl]

I'm used to working with containers in Docker... from this video it seems like LXC containers behave really differently, really more like a VM than a container meant to run a single process

[@LearnLinuxTV]

Very different, like the virtual machine equivalent of a docker container.

[@thefullstackworld]

Look for LXD it is built on top of LXC, I hope that will help you

[@glidentity]

@@LearnLinuxTV but what is the difference between a VM and lxe? Because I can see the difference between docker and a VM but I really struggle to see the point/advantage of a lxe compared to a VM (at least templated VM). Édit: maybe a good idea for a video

[@tomasfasth2956]

@@glidentity VM=it's own kernel with emulated hardware. LXC=sharing host kernel but with boundaries, limited access to system resources.
