Nginx Proxy Manager

"Nginx Proxy Manager is a tool that lets you expose your private web services on your network with free SSL, Docker, and multiple users."

Custom domain

To utilize NPM as a reverse proxy with SSL, it is recommended to obtain a custom domain. FreeDNS providers that offer free domains are also a viable option.

At the core of the home server is Nginx Proxy Manager (NPM), functioning as a reverse proxy routing requests to various applications. Most applications are isolated within the docker network proxy-network but remain accessible through NPM. NPM exposes ports 80/443 (HTTP/S), handling all requests to *.fjellhei.men and directing them to the appropriate containers.

For guides and detailed instructions on setting up and configuring the reverse proxy based on your existing network, refer to the documentation.

Portainer

"Portainer is a lightweight service delivery platform for containerized applications that can be used to manage Docker, Swarm, Kubernetes and ACI environments."

SSH access to the server is restricted to devices with authorized keys, making server management challenging from unauthorized ones. Portainer fills this gap by offering a web-based UI for Docker container administration accessible from any device's browser.

Tailscale

"Tailscale is a zero config VPN that works on any platform, service, or runtime."

To remotely access the home server without exposing it to the internet, Tailscale utilizes the WireGuard protocol, creating a secure network called "Tailnet" for connected devices. This allows seamless access to server apps from anywhere, using different IP addresses.

Consult the documentation for instructions on how to set up and use Tailscale.
