Followed this guide about a month ago, single IP to my proxmox server and the few vm's i had deployed has net access. But when I try to add a new pub IP cant seem to get it to work. Anything in this guide that is preventing this? VM's with no pub ip are using vmbr2 and work, so this new VM w pub IP should be using vmbr1 right? What am I missing to do? Many pre-thanks!

I'd rather buy a subnet and give the VMs their own IP than have to SNAT and DNAT

Thank you so much man. There is a saying in here which you are living proof of that. Which is "We would have build his statue but there is not enogh concrete for his balls.". Great Tutorial.

Tell me , tell me you earn in millions from your gigs Otherwise i will be sure that AI will take my job BTW if you ever decide to sell course under 30 dollars USD i will be biying it Also share your knowledge regarding application security and developing

Wow, this method with QEMU is awesome, thank you! I wish Hetzner promoted it themselves. It's so much easier than request for a KVM Console and hassle with attaching ISO there.

I also recommend to look at their auction servers. I have a beast of a machine (AMD Ryzen 9 5950X, 1TB NVMe + 2x2TB NVMe, 4x32 GB RAM) for basically around 100€ a month. I use it for learning mostly, and we have clustered vSphere/ESXi at work so I use that whenerver I need to learn/implement some clustering stuff. Best of both worlds I guess lol

This is very helpful and one of the best guides for eBPF XDP! Good Job

Awsome video, clean and informative! A interesting follow up would be how to hook this up with the CI part. commit, build test to creating the artifact that is releasable here.

That was excellent, very clear and informative, I'm already looking forward to more videos. One question, I am curious what is a good folder structure for a production ArgoCD with several environments and apps.

This video series has been invaluable. Thanks 👍

Fundamentally.

any idea how to use OPNsense as the main router for the VMs with a failover IP from Hetzner in a 3 node cluster?

This is hands down one of the best Docker references on RUclips! I've already shared it with my peers-hoping they become even more grateful for my Dockerfile wizardry. 😁 By the way, could you share details about the small tablet you use for drawing? It looks super handy!

This was an excellent video! Got recommended it out of the blue and it should definitely have more than a couple hundred views! I use docker on a daily basis for hosting production apps and I will definitely be using the information from this video on them. Thanks sm and keep up the great work! Next thing I'm doing is binging the rest of ur catalog

I just got this recommended out of nowhere. Most of the time when building Docker containers, I would just copy bits from various Dockerfile's and get it to work somehow, but it would always end up with some unexplained bugs after some months down the line, and I would just franticly try to resolve these issues by copying more stuff around. There was this nag that I should really learn this in a more abstract holistic way, but "there's never time" for something that ends up working just fine for 8 more months after a little bit of stackoverflowing. Watching this got me really excited about building docker images! How cool is that you share all of this! And I love your style in explaining it all by building from fundamentals! Great stuff! Thank you so much for putting it out there! 🫶

You’ve got some top tier content, keep up the good work, it’s definitely appreciated! 😁

Is this like for running / building other peoples code and avoiding it escaping chroot and namespaces?

Everything is cool until u can be sure they will not compromise you :) u never know

Great video! This ties really well in with fluxcd concept of multitenancy and add a seperation with git sources as well allowing developers to have a cicd setup with in their own repo and deploying from there as well in to their own namespaces that is allocated for them. Regarding resources, wouldn't it be better give every developer team their own namespace and then build resource quotas on that namespace. That will give you fair use in the cluster and it builds a great dashboard for who is using how much.

Traffic on vswitch is limited to 1TB/month. Each more TB costs 1 euro.

Great video! Thanks a lot!

Note - You CANNOT join cluster if you have VMs already created on a node !!!

Thanks @PolitePixels ! Can you do extra video for simplier more common setups and hetzners failover IP ? Basically 2 machines, wher one replicates from another, and in case of hardware failure failoverIP could be switched to another machine ? Also Proxmox BACKUP server seems very powerfull, and would be good to have video tutorial on that ? Thanks !

PS.: on minute 5:46 when is creating a cluster you should change to vmbr1 and not use vbmr0. On video show the public IP, this is bit confusing, but that should be the private IP 192.168.50.11. If you didn't pay attention this will give a ssl error and the PVE2 not connect. To fix you need change the file: /etc/corosync/corosync.conf in file change ring0_addr: to 192.168.50.11 on totem config change the version number: config_version: 3 Save the file and copy it to cp /etc/corosync/corosync.conf /etc/pve/corosync.conf ...stop all these services pveproxy, pvedaemon, pve-cluster, corosync. .. And delete all files in /var/lib/corosync/* than restart the service at this order: corosync, pve-cluster, pvedaemon, pveproxy ... You need to do this process on all node... thanks for great video!!!

eBPF basic example wirte ebpf_probe.c but runner.py path(ebpf_watch.c) ?? not good example indeed

Great tutorial! Thank you. How auctions work in hetzner? if i buy a machine from auction will the peocess be same for connecting to the machine or setup

Now if I have a bunch of lxcs and few containers inside a Ubuntu vm, how do I access them through the internet?

Hi very nice tutorial. Just a question. Do you have a bug in your DNS setup? I think 4.4.4.4 is not DNS, shouldn't it be 8.8.4.4 from Google?

Super helpful video, thank you!

What is this seth thing?

I would pay for a more in depth version of this that expands on some of the concepts covered, as the last video (Pt 3) went in to some concepts I had absolutely no idea about, and while I can follow along, I would like to understand what and why.

Would be nice if a script existed to take care of a lot of this.

After doing sudo ifreload -a i lose all connection to the ssh.... Can still access with VNC though. But after doing everything after that and rebooting out of rescue it won\t connect to the ssh anymore. What is going on here?

Hi, could you make a video about pfsense with proxmox? 🙏🙏

What is the reason for the 3 partitions. I guess one is for EFI/Bootloader but for what is the other one?

also interested to see if SDNs can work seamlessly with Wireguard, rather than using a vSwitch

You made it Unbelievably simple 😊

Good one.... Ceph on 1 gb network is asking for disaster. I would recommend minimum of 10 G. Secondly, with ceph, you will never get snapshots. I generally prefer a Linux box with max possible drives as storage to Proxmox storage. I also prefer nfs over any other fancy stuff like smb/cifs or iscsi for its simplicity, able to mount any where in case required.

There is much better way to install Proxmox. Simply install stock Debian. Then you can install proxmox over debian. No need of rescue mode and additional stuff. Always install with default drive and then order additional drives.

VNC asks me for a password. In your qemu-system-x86_64 command, you don't specify any password for VNC. Could give me hint what I might be doing wrong?

How i can acces via RDP to a windows machine?

At the Current situation we need go to lesser pricing not on the higher side

Would it make sense to use pfSense or OPNSense to handle the firewall rules and DHCP?

Awesome video, one the best explanations 👍

Advice: i found out that sometimes the networkcard has 2 altnames, when i used the second altname i wasn't able to boot into proxmox, but when i use the first altname it works!

hi thank you so much. But pastebin link is broken. Can you fix it please

I got it working without rescue mode at one point, but then I restarted the machine and now I cant longer access proxmox, I have to go into rescue mode and boot a vm from rescue mode. Wtf am I doing wrong?

Wow I thought the only way to install proxmox on hetzner was through the installimage script. I've tried with installimage, but had the issue of mdadm raid enabled + wanting to use zfs instead (also bad idea to put zfs on top of mdadm), and couldn't just put the filesystem in the script (it doesn't support zfs). This a very cool way to installing an os on hetzner machines, allows for much more customization thank you very much !!

After following guide and rebooting (without using backup link and "source /etc/network/interfaces.d/*" ) system is not reachable. I was trying few times to reinstall system.
