Docker Projects for Raspberry Pi (or Linux)

"Docker is used on Raspberry Pi to run isolated applications and services, avoiding conflicts with the system or other software. It simplifies installation and management across multiple environments."

"What You'll Need for These Projects:
    Raspberry Pi 4 or Pi 5.
    Micro SD card: 32 GB or more.
    Raspberry Pi OS installed.
    Docker & Docker Compose installed.
    Knowledge of Docker and Docker Compose."

"Pi Hole (https://pi-hole.net) acts as a local DNS server that blocks unwanted content before it even loads. Once set up, everything connected to your Wi-Fi gets ad-free browsing." Documentation: https://docs.pi-hole.net/
"Using a Pi-Hole in a container makes it isolated and easy to upgrade, without affecting other services on your Pi."
Requires: "Setting your router's DNS to point to the Pi."

"Home Assistant helps you control smart lights, thermostats, sensors, and more — all from one dashboard. It supports hundreds of devices and is incredibly customizable."

"Jellyfin and Plex let you stream videos, music, and photos from your Pi."
Plex has been around longer, but Jellyfin is apparently easier to setup & use.

"Monitor Everything with Grafana & Prometheus:
Track your Pi's performance, network stats, or even multiple devices in your home. Grafana gives you charts and dashboards, while Prometheus handles data collection and time-series storage."

"Vaultwarden is a lightweight clone of Bitwander that you can host yourself. It's perfect for keeping all your login credentials secure and syncing across devices."
"Enable HTTPS for better security."

"WireGuard VPN lets you access your home network securely from anywhere. You can browse safely on public Wi-Fi or access your NAS and Pi tools while on the go, and on the other hand, it gives you privacy and encryption for your navigation."
"While using a container, you can avoid editing the system file directly, and you can spin it up on any device as many times you want and at any time. No need to mess with iptables or system networking by hand."
Requires:  "Port forwarding on your router." & "Static IP or DDNS."

"Run small AI models on a Raspberry Pi! With tools like Whisper (speech-to-text) and LLMs like x, you can experiment with local voice transcription or chatbots without needing cloud access."
"Docker is perfect for this because it isolates Python environments, dependencies like PyTorch, and makes setup much easier."

"Host your own Minecraft server hosted entirely on a Raspberry Pi."
"With Docker, you can isolate the game server from your OS, and make it easy to restart or tweak settings without breaking your Pi."
 
"Host a Simple Web Server or API Backend - If you're learning web development or building your own tools, using tools like Node.js, Flask, or PHP servers on your Pi is the best way to deploy them.
It can be used for hobby apps, dashboards or even self-hosted APIs."

"Create a Private Document Server - Paperless-ngx lets you scan, store, search, and organize documents in a sleek web interface. It's perfect for managing receipts or home paperwork."
