Xen Orchestra from source with Let's Encrypt certificates

gskger

@olivierlambert Regarding XCP-ng - just generated a Let's Encrypt certificate for one of my xcp-ng test hosts xcp01.myplaylab.net (XCP-ng 8.2 beta fully patched), replaced the /etc/xensource/xapi-ssl.pem with the LE certificatexcp01.myplaylab.net.all.pem while keeping the name xapi-ssl.pem and did a xe-toolstack-restart. That seems to work, since I get a valid LE certificate and secure connection when accessing https://xcp01.myplaylab.net. Could it be that simple ? Do not have a pool and xo available right now, so just wondering...

I was just too curious - the xcp-ng test host can be added to Xen Orchestra with the LE certificate - no need to accept unauthorized certificates anymore

Now you can even replace the cert via XO web UI (see https://xen-orchestra.com/blog/xen-orchestra-5-52/#xcpngxenserverhostscertificatesmanager)

Hi,

I'm testing using certbot to install SSL cert for XOCE using Lets Encrypt instructions but need to know what is the path for XOCE webroot?

Thx,

SW

@stevewest15 those instructions will not work as XOA is running on node and does not have a physical "web root" folder like you are thinking of. Also @gskger please be cautious about scheduling xo-server restarts, doing so interrupts and breaks any task xo-server is running at that time, like backups etc. I believe this is one of the main reasons we haven't implemented let's encrypt integration into XOA, it's not as simple as just firing off an xo-server restart everytime LE certs are updated - this would break a lot of important backups for the majority of our customers. We would need to add some type of sensing to see xo-server's current status, and schedule the restart for when there's no longer any tasks running

gskger

@fohdeesha good to know, thank you. Maybe setting some xo flag through cli telling xo-server to restart when convinient might be a way to automate the process of cert updates?

@gskger Why don't you install acme.sh or something similar on XO host and deploy from there. No need to use pfSense.

@fohdeesha Does a HUP signal reload the config? Can it also check for updated certs?

It's not a restart it's just a config change check.

gskger

@kevdog Internal server can not be reached from the internet (no port forwarding so no HTTP challenge) and my hosting provider does not have an API for DNS challenges. Thats why I use pfSense "on the edge" at the moment. I admit that a cheap VPS runing acme.sh could do the trick, but my automation works and I am lazy .

The real solution will be to get XOA as a certification authority and then manage all XCP-ng's hosts certs

gskger

Having XO from source or XOA act as a certification authority for the XCP-ng hosts is for sure a good approach. Would be great if that could include the VMs running on the XCP-ng hosts, which is my main goal (apart from being able to HTTPS into XO from source of course).
