I have been real busy the last several weeks re-doing my homelab. New server, new switches, upgraded to Proxmox VE 9, etc etc. Still have some stuff to do including documentation :>) but I want to start down the "Docker" rabbit hole. The new server is a Dell Poweredge R630 (replaced an R710). It has (2) E5-2680 processors for 24 cores and 48 threads, 128GB of DDR4 ECC Ram, (2) 256GB SSD's in a zfs mirror for Proxmox VE, (6) 1TB 7200RPM Sata III HD's in a zfs raidz2 profile, and (4) 1GbE network ports. Currently have (3) VM's and (9) LXC containers running. With all that said I am planning on a Debian 13 VM for Docker. My question is how would you provision it? How many cores? How much ram? How much disk? My first project may be Authentik with either Nginx Proxy Manager (which I already have running in an LXC container) or switching to either Traefik or Caddy. (Brandon i have read your post about Authentik with Traefik), but want to do some more research before I dive in. Sure would appreciate any advice y'all may have! Chuck

For those interested in upgrading....I posted a new detailed walkthrough of steps and things to think about with upgrading Proxmox VE 8 to 9: https://www.virtualizationhowto.com/2025/08/how-to-upgrade-from-proxmox-ve-8-to-9-fast-and-hassle-free/

For those using Telemate as your terraform provider there is now a fix in place related to the Proxmox 9 permission issue in the release of 3.0.2-rc04. There are some changes you will need to be aware of with this release. 1 - A CPU block is now required. 2 - In the network block, it now require a network ID. The network ID needs to be in sequence. ie: 0, 1, 2, 3 etc. Here is a example of the terraform code with the changes I am currently using.. resource "proxmox_vm_qemu" "<TF Module Name>" { name = "<Server Name>>" target_node = var.pm_node clone = var.pm_template3 vmid = <VM ID> agent = 1 onboot = true os_type = var.os_type qemu_os = var.qemu_os ciuser = var.ciuser memory = <Memory Size> tags = var.tags_11 ######## New CPU Block ######### cpu { cores = 4 sockets = 2 type = "host" } #Display vga { type = "virtio" #Between 4 and 512, ignored if type is defined to serial memory = 512 } scsihw = "virtio-scsi-single" bootdisk = "scsi0" disks { ide { ide2 { cloudinit { storage = var.pm_storage } } } scsi { scsi0 { disk { storage = var.pm_storage size = 100 iothread = true cache = "writeback" emulatessd = true discard = true } } } } sshkeys = <<EOF <SSH Key Here> EOF lifecycle { ignore_changes = [network, sshkeys] } ######## Network ID ######### network { id = 0 model = "virtio" bridge = "vmbr1" } ipconfig0 = "ip=<Server IP/CIDR>,gw=<Router Gateway IP>" nameserver = "<DNS IP> } After updating the provider and running Terraform inti, you will see errors in your main.tf file. Also if you run a terraform plan, you will receive the following errors if you have already created previous VM's. Error: Unsupported argument │ │ on main.tf line 99, in resource "proxmox_vm_qemu" "Module Name": │ 99: cpu = "host" │ │ An argument named "cpu" is not expected here. Did you mean "vcpus"? ╵ ╷ │ Error: Missing required argument │ │ on main.tf line 143, in resource "proxmox_vm_qemu" "Module Name":

Just FYI for those using VMWare. https://www.youtube.com/watch?v=AN_3ps5bl7o&t=13s https://www.zerodayinitiative.com/blog/2025/5/16/pwn2own-berlin-2025-day-two-results

If all goes well, the WTR MAX should ship tomorrow, and now I'm trying to decide what OS or hypervisor I should install. - TrueNAS is an option. It's a good NAS but for all sorts of reasons, I rather run VM's and docker elsewhere. - Proxmox with TrueNAS inside is an option. Unfortunately, there is no guidance on running TrueNAS in Proxmox on the platform. No idea if I can pass a SATA controller. Any suggestions or ideas? Thanks.
