Looking forward to a Packer + Terraform video. I'd also be interested to see how Packer (and Terraform) could work with LXD too. Proxmox is great but, as everyone knows, it requires a Debian base, whereas the snap version of LXD will run on just about any arch or distro and also provides both VM and CT instances with clustering features. It's just missing a standard web GUI like Proxmox.
Great video. Very pleasing to follow. Very clear: You ve put a framework by putting the most important principles first, Then putting details with why, what, steps and tools on those principles, and by linking logicaly the principles. Few have your redactional qualities. One way or another, you have to teach.
I discovered you recently. In general, you are explaining such nice tricks to a person who does not know the subject :) Congratulations, I wish you continued success . Bravo
Hey, first of all, great video. You have packed up lots of info in this video. As a new packer user I had to deal with the plugin installation which was not a part of the video but I can understand that we cannot go over everything and we need to make hard choices in order to simplify the content. For those who had error messages about unknown source, you need to define the plugin to be used and then initialize packer in order to install that plugin :)
@@insanity.k As mentioned, you can either use the proxmox-iso option to create an image from iso, or maybe the better option, create an image from virtual machine you already have using the proxmox-clone
@@TheJoBlackos Kinda new to Packer - I want to use the proxmox-iso plugin. But how do I use that? Where do I define using the proxmox-iso plugin and how to initialize packer in order to install the plugin? Thanks in advance!
vielen Dank für eure tollen Videos! I had a similar path to using Packer and CloudInit to create VMware Fusion VMs. One hard lesson learned was to not use one's existing vm directory for the output target directory - it gets cleared (its in the docs, i just missed it). Ask me how I know - I lost all of my existing vm images. Oh well, I needed to do some house cleaning anyway. The automation is cool, but the CloudInit hack of intercepting the installer and injecting keystrokes just seemed really kludgy to me, sensitive to getting delays right and other frailties, when I learned that's how it works. My spidey sense is that automated NixOS VM creation would be way more robust, but I'm a toddler noob at Nix right now so I'll look into that down the road.
Hey for me the boot gets stuck at cloud-init running init-local in the console and the script is waiting for ssh to be accessible....would you happen to know any fix ?
Ok, a bit late maybe, but check what is happening in the Proxmox console on the newly created VM. For me packer fails to unmount the ISO which means it will start the installer script again on reboot instead of booting the new server. This appears to be an unsolved bug.
Another AWESOME video! I got my two templates up and running after a few tries. One thing on the docker one is that also added docker-compose as well. Now with the release of Ubuntu 22.04 LTS, I thought that I could just clone the scripts - change names, etc. and it would work. To my sad surprise, it would appear that boot commands between 20.04 and 22.04 are different. Will have to try and dig in and find out what they are.
Hi@@christianlempa , facing similar issue. Autoinstall stuck on language selection with Ubuntu 22.04.4. Your boilerplate scripts refer to Ubuntu 22.04 which is can not be downloaded. Thanks!
I just watched @Techno Tim's video on this very topic. So cool to get 2 different perspectives on the same topic within literally days of each other. Thank you!! 😁
Are you using LVM? because I'm gettning this error " unsupported format 'qcow2' " apparently LVM doesn't support that if I set it to raw it does work but just wandering
Hello, I tried to build a template using your tutorial but i get an error: wasm connection closed by the server ( being proxmox ) I have latest version of Proxmox. Do you have an idea? Thank you ! Regards
Great video. Have you tried running this lately, with 24.04? Been troubleshooting for hours, can't seem to get it to work. I get sent to choose language and keyboard layouts and stuff on the ubuntu installer, doesn't seem like my settings are being passed in...
Can I use it in Virtual box or VMware the proxmox installation what u recommend and how to remove the pre-build tools in linux and making to install own tools
Hey, I have the problem that the VM has no internet when it hangs in the boot CMD and therefore can't reach the webserver. the dhcp server works though.
Thanks for your video! Does the SSH users need to exist in order to build the VM or will packer create that? I assume it needs to be created before had to use the private SSH key. Also how would I enable cloud-init on proxmox?
But why I must create an install template which I use only one time and then the machine is there. then it's a template and I don't need to install it anymore
Hey, I just followed your example and it works (with ssh keys) however if I switch to password it fails. Did you try using password for ssh credential?
FOUND IT! During the cloning of the image changing the user in "Cloud-Init" screen has some bug. When the user name is left empty (it will show 'Default'), cloud init will greater a new user 'ubuntu' in addition to the one specified by the packer template. The password which you change in Proxmox Cloud-Init will be assigned to .... wait for it ... to ubuntu account and not the one specified by the packer temple. This is VERY screwy indeed. I did not test if the packer defined user id in such situation will simply get no password. To late to test it tonight.
Christian Packer sounds great but it is important to know how to create vms containers & templates by hand to understand what is going on. Automation is good till it goes wrong .
Quick question: When I want to create a quick vm on my proxmox system right now, all I do is clone the existing vm and run a bash script that modifies the mac, ip and hostname. I reboot the vm, and it works like a charm and only takes a few minutes. Simple and easy. Is this a bad workflow?
Hey TheDigitalLife! Your Videos are very thorough and to the point. I followerd your Traefik Video and it provided me very good concepts. Could you also make another Video on Ingress in k8s and how we could secure it both in ipv4 and ipv6 address?
Thanks for the great video. Please i need some help on how i can passthrough my h710min hba pcie card to my truenas vm in proxmox. I have a dell r720xd server.
@@christianlempa he was referring to ready made official cloud-init images, just like Techno Tim did a few days ago... those steps can be automated using ansible (download image, create proxmox vm, attach disk, create template). To customize the images, one could use libvirt tools beforehand
Yes. If you are the only contributor to your infrastructure and it lives only on proxmox, and you rarely update or version your software. No if you work on a team, use more than one environment, or need to manage patching in a highly regulated security environment
Interesting process, but, this smells like it's a 1:1 build? I know this is a year old video, but I kinda stopped taking notes as soon as I saw a lot of inputs that are pretty static when it comes to new machine builds. Like, defining IP addresses? Assigning the VM an ID to ProxMox? What if I wanted to spin up several VMs for different purposes based on this template, this seems pretty "stuck" to how the template file is configured, and you'd have to go edit/copy the config files every time you want something different for the next VM, like the ID or static IP address, or whatever the case may be. This process just doesn't seem like it's going to save time compared to just running a base template, and copy/pasting a set of commands out. Am I missing something here?
Hi Christian! Thank you so much. I learned so much from you and your videos look great. I followed the tutorial and everything worked as expected, but if I try to make more than one VM they share the same IP. I tried everything I could think of including one last provisioner "shell" { inline = [ "sudo cloud-init clean", "sudo rm -f /etc/machine-id", "sudo rm -f /var/lib/dbus/machine-id" ] } But the IP keeps persisting. I've looked into other tutorials on cloudinit where this seems to be a consideration, but I don't know what to do in Packer
@@JustinWallis No errors unfortunately. That's why I'm having difficulty diagnosing the issue. Everything seems fine, but in the end I always get the same IP.

Hey! This was a great video, I ran the same install with your new 22.04 packer proxmox templates but the boot is hanging on "[ OK ] Finished Load AppArmor profiles managed internally by snapd", did you see anything like this?
One last thing I noticed, the 22.04 template doesn't work with ssh passwords even if the autoinstall user-data and packer hcl file have the exact same entries. It worked once I used ssh keys instead. The following was the error if you're interested: Error waiting for SSH: Packer experienced an authentication error when trying to connect via SSH. This can happen if your username/password are wrong. You may want to double-check your credentials as part of your debugging process. original error: ssh: handshake failed: ssh: unable to authenticate, attempted methods [none password], no supported methods remain
thanks for the video as it is very helpful... one question that maybe someone can help with: the packer automation fails when I try to use ssh password instead of public key authentication and I get the following error message: Packer experienced an authentication error when trying to connect via SSH I have googled on this issue but still unable to get past the ssh authentication. Any hint is greatly appreciated.
Wait, wouldn't it be faster to just spend the time to make a VM manually, keep it as a VM iinstead of converting to template and just clone it when you need another instance? By keeping it as a VM to maintain the ability to do updates and other changes. Why do a whole installation every time, even if automated, when you can just clone a "template" VM in seconds? And why cloud-init when packer seemingly is able to do all the same stuff?
Honestly i prefer to use lxc with docker inside. They work better tham VMs in resource limited environments - no virtualisation overhead and much better flexibility in adjusting assigned resources. The only vm i have is pfsense. I cant afford for special virtualization licenses to vitualize other os like windows or macos. I know that some abuse trial licenses or even use keys from physical machines but their license dont allow that, so such actions are plain piracy.
