Hi,

I'm currently working on a hardened pve installation for CIS
certification, and as it need luks encryption + specific partionning,
I need to install it on top of a debian install.

I would like to deploy pve-enterprise repo directly, but how can I do 
it on top of debian ?

The wiki said to install no-subscription first, then switch to
enteprise after uploading the key in the gui
https://pve.proxmox.com/wiki/Install_Proxmox_VE_on_Debian_12_Bookworm

But that mean than more recent packages could be pushed from no-
subscription first.

Is is possible to put the key somewhere in /etc/apt/ ?

Alexandre

Hi,

It's been a while since I've had to do such things.. but here goes..

Unless you have an offline key, you'll need to register the server 
first, so that the server ID (hex version of the md5 hash of the SSH RSA 
key) is allowed.
Basically, as you can see in proxmox-subscription/src/check.rs:
you need to call:
https://shop.proxmox.com/modules/servers/licensing/verify.php
with that JSON (challenge is epoch time + random string) :
{
         "licensekey": key,
         "dir": server_id,
         "domain": "www.proxmox.com",
         "ip": "localhost",
         "check_token": challenge,
}

Then either you re-register/check it once you have the API available, or 
you try to write a valid /etc/subscription file..

Otherwise, it's "simple", you can get the info on a running server:
/etc/apt/auth.conf.d/pve.conf
machine enterprise.proxmox.com/debian/pve
login server_id
password server_key

Set the proper enterprise repos, and it should work, if the server ID is 
registered...

This might be interesting to have in the ansible role lae.proxmox (that 
you'll probably despise, given your love for ansible HAHA) as well, as 
the only supported scenario for now there is to.. remove the enterprise 
repos.. either have a curl command to register the server id and compute 
/etc/subscription, or a tool (pvesubscription) to wrap that Rust API in 
Debian..


Cheers,
Gilou

And of course, Thunderbird missed that you already had an answer from 
Shannon regarding POM use, but that's another route.

Thanks Gilou ! 


(I'm going to use ansible for this setup deployment,  no puppet :p )

I'm using it for hardening
https://github.com/ansible-lockdown/DEBIAN12-CIS

so, I'll add deploy && tuning of proxmox too.



See you at Fosdem !

The most straight forward way to do that with our current tooling is
probably to leverage POM [1]. It should allow you to mirror the
enterprise repo and then you can configure the PVE host to use that
mirror. You can also use POM to activate the subscription key on the
node.
