Congrats on getting everything working - it looks great!
One piece of (unprovoked, potentially unwanted) advice is to setup SSL. I know you're running your services behind Wireguard so there isn't too much of a security concern running your services on HTTP. However, as the number of your services or users (family, friends, etc.) increases, you're more likely to run into issues with services not running on HTTPS.
The creation and renewal of SSL certificates can be done for free (assuming you have a domain name already) and automatically with certain reverse proxy services like NGINXProxyManager or Traefik, which can both be run in Docker. If you set everything up with a wildcard certificate via DNS challenge, you can still keep the services you run hidden from people scanning DNS records on your domain (ie people won't know that an SSL certificate was issued for immich.your.domain). How you set up the DNS challenge will vary by the DNS provider and reverse proxy service, but the only additional thing that you will likely need to set up a wildcard challenge, regardless of which services you use, is an email address (again, assuming you have a domain name).
Thank you for the* so much wanted advice, it's one of the reasons I actually posted this, to get advices on how to do things better.
I've been trying to do that for a specific service running (firefly) but I can't figure out what to do exactly, about the domain name, Is there a way to do that without one?
You can get pretty cheap domain names if you google around. I managed to get mine for £35 for a number of years (3 I think, I was high when I set it up) and got a .com name out of that.
You could look into DuckDNS. I know I used them many moons ago for Home Assistant but can't quite remember what the capabilities were, I just remember it was free and a bit rubbish. But as a stopgap it works.
Try that for a bit until you have a few quid spare, then get yourself a domain name paid for a while.
I used dynv6.com to get a free subdomain e. g. [name].dynv6.net and then a swag docker to do the reverse proxy subfolder->dockerport matching. Trafic in my home network is http and the swag ports are the only one exposed to the public. When I find the time I'll do in depth setup guide including the ipv6 setup problems.
Have a look into Heimdall or Homarr. Much easier, don't need to worry about addresses at all. Single set up and add Tailscale exit node for external access.
I've been fiddling with it again today and (using Homarr) my only services that don't work when I access through Tailscale are the ones I use names for (are.local, server.local, etc) and I can access them when I use the IP:port so when I get home I'll just change them to IP:port on Homarr and I'll be all good
Yea I'm using Homarr, I've just finished setting everything up. The only problem I have right now is that I can't access Syncthing GUI through the domain.
@Mir@rhymepurple Another place you can get free domain names is freedns.afraid.org - they have been around nearly forever and all you have to do is log into their site and go to any page once every six months (I guess so they know you are still alive) but they will email you a notice a couple weeks before that time is up. And at least for me they have always been very reliable.
Everything I mentioned works for LAN services as long as you have a domain name. You shouldn't even need to point the domain name to any IP addresses to get it working. As long as you use a domain registrar that respects your privacy appropriately, you should be able to set things up with a good amount of privacy.
Yes, you can do wildcard certificates through Let's Encrypt. If you use one of the reverse proxies I mentioned, the reverse proxy will create the wildcard certificates and maintain them for you. However, you will likely need to use a DNS challenge. Doing so isn't necessarily difficult. You will likely need to generate an API key or something similar at the domain registrar or DNS service you're using. The process will likely vary depending on what DNS service/company you are using.
