You if you own the domain example. We have previously suggested temporary TCP port forwarding or obtaining the cert on one temporarily public machine and then copying it and the private key onto a non-publicly-visible machine.

I think the most secure approach is to generate a private key and CSR on the internal machine and then use manual mode on a temporarily publicly-visible machine which has the public DNS record pointed at it. None of the workarounds really work for that case. Obviously, full DNS based validation is the end-state easiest answer to this.

I have absolutely same problem intranet. And at least if all Windows machines are in a windows domain it is even piece of a cake to distribute the CA into the trusted CA certificate store from what I know. Being able to fully automated it, with known trusted certs, using the easy capabilities provided by LE would be ideal. If that would really be the case, the question would not have been brought up in the first place.

That indeed can be a problem. I only wanted to offer a possible solution. Production server has a known bug though with certain DNS providers that is in process of being fixed upstream. My use case is a server behind NAT. After reading this thread I set up local. I then tried to generate a new certificate using the SAN capability by using what appears to be the otherwise undocumented mechanism of multiple -d example.

It did, but it appears that resolving to a private IP is the same thing as not resolving. It would be nice if the error was a little more helpful, if this is the case. So I changed the A RR for local.

I then changed local. And so now I can make uninterrupted access to jimmy locally using local.

Way too much effort, but I wanted to know it could be done. Taking the server down for renewal is bad enough, but messing with the DNS is worse.

The TXT-record needs to be created in public DNS since the Let's Encrypt validation servers, not the certbot client, needs to be able to resolve the record. If it all happened locally the validation wouldn't be worth much.

The server for which the cert is issued can be completely private though. MartijnHeemels Well, now I can't understand my this old comment any more. Bind9 has the so-named "views" for that.

After that, the keys can be mirrored into the intranet with rsync scripts. MartijnHeemels I am doing this because at the time I had troubles to automatize the zone-based authorization of the letsencrypt.

Maybe now it would work, but honestly I am not very satisfied with letsencrypt in general well I think we all know the attitude of the bosses about "make it better" tasks like this.

Yes, something like this is what I have, a domain valid on the internet and I need to create another subdomain valid only for my internal network. My internal DNS windows R2 would be responsible for validating my intranet. Could you give me more details if it is possible to use a LE certificate?

Yes, you can obtain an LE cert for any real domain or subdomain of any real domain. You can obtain practically any possible real name and wildcards to cover entire subdomains of real domains through DNS validation.

I understand, I also have an external DNS that is the one we manage for our valid domains on the internet. And finally, will I have to do the same work every 90 days?

MikeH-R Good question - I would say a gitlab-ctl reconfigure is not necessary since the configuration itself doesn't change, but to make nginx and probably other components pick up the new certificate a gitlab-ctl restart should be done.

Probably a gitlab-ctl restart nginx is enough. JakobLenfers Thanks, I changed the answer! Hay Hay 1, 15 15 silver badges 26 26 bronze badges. One thing, and then i'll be able to mark your answer and "the answer", where is the gitlab webroot?

I was unable to identify a webroot. In my case I have been using Apache to generate my certificates, and I believe --standalone should be used in this case as per letsencrypt.

It simplifies the process by providing a software client, Certbot, that attempts to automate most if not all of the required steps. Currently, the entire process of obtaining and installing a certificate is fully automated on both Apache and Nginx.

In this tutorial, you will use Certbot to obtain a free SSL certificate for Nginx on Debian 9 and set up your certificate to renew automatically. This tutorial will use a separate Nginx server block file instead of the default file.

We recommend creating new Nginx server block files for each domain because it helps to avoid common mistakes and maintains the default files as a fallback configuration. Both of the following DNS records set up for your server. Be sure that you have a server block for your domain.

Certbot is in very active development, so the Certbot packages provided by Debian with current stable releases tend to be outdated. The backports repository includes recompiled packages that can be run without new libraries on stable Debian distributions.

This includes the main packages, which are Debian Free Software Guidelines DFSG - compliant, as well as the non-free and contrib components, which are either not DFSG-compliant themselves or include dependencies in this category. Certbot needs to be able to find the correct server block in your Nginx configuration for it to be able to automatically configure SSL. To check, open the server block file for your domain using nano or your favorite text editor:. Then save the file, quit your editor, and verify the syntax of your configuration edits:.

If you get an error, reopen the server block file and check for any typos or missing characters. Once your configuration file syntax is correct, reload Nginx to load the new configuration:. Certbot provides a variety of ways to obtain SSL certificates through plugins. The Nginx plugin will take care of reconfiguring Nginx and reloading the config whenever necessary.

To use this plugin, type the following:. If this is your first time running certbotyou will be prompted to enter an email address and agree to the terms of service. The configuration will be updated, and Nginx will reload to pick up the new settings. Your certificates are downloaded, installed, and loaded.
