Hello everyone! I have been lurking here on c/selfhost for a while now and wanted to share my experience with my setup. Here is my setup:

Its an "old" enterprise Dell 630T I bought second hand. 36 Cores, 256GB DDR4 ECC RAM, and 8x 4TB HDDs.

On it i run Harvester HCI that runs two VMs one is TrueNas Scale that has full pcie passthrough to the raid card that is in IT mode for full control of the HDDs. The other VM runs a single node RKE2 cluster with Rancher installed.

I want to use the Rancher integration with Harvester to create a RKE2 cluster ontop of VMs created by Harvester. The plan is to then install a K8S CSI driver to connect a NFSv4 share from TrueNAS to harvester or the Rancher installed VM cluster.

I'm already aware this is weird setup but I wanted to start learning more about Kubernates but still have a "simple" way to set it up and manage it.

Honestly I don't know what to share about my experience creating this setup, so feel free to share your thoughts and ask questions about it!

To be clear I'm a beginner and I'm a bit overwhelmed with all the information I found and not completely sure if the information I found is up to date or outdated and I figured I would just ask here to get some clear answers.

What I want to achieve:

• have TrueNAS Scale web GUI and installed apps like Nextcloud or Photoprism be remotely accessible
• have that remote access be secure
• use my registered domain instead of the IP address of my server to access the TrueNAS Scale web GUI and the installed apps
• don't have certificate warnings when accessing all this over HTTPS

Can someone explain to me how I achieve this or point me to a guide that walks me through it? I appreciate any help I can get.

I already managed to setup Tailscale and managed to access my server through that but then I got stuck on how to set it up to use my registered domain name to access the server.

So the next thing I tried was using the DynDNS of my Fritzbox but unfortunately it seems that Cloudflare (where I have registered my domain) does not provide a "update url" which the Fritzbox DynDNS GUI requires to set it up. This was to use it in combination with port forwarding and Wireguard (this is the guide I was following: https://www.wundertech.net/how-to-set-up-wireguard-on-truenas-scale/)

I also found this guide: https://notthebe.ee/blog/easy-ssl-in-homelab-dns01/ but that's for servers without TrueNAS and I don't think I'm experienced enough to transfer it and apply it to TrueNAS.

So yeah, I'm overwhelmed by information and I need help.
