Understanding the Tools: CasaOS and Tailscale

Before diving into the installation, it’s crucial to understand what these tools bring to the table. CasaOS provides an intuitive interface to manage your Raspberry Pi with ease, complete with an app store packed with useful utilities. However, it’s worth noting that development for CasaOS has ceased, with efforts shifting towards Zema OS. Despite this, CasaOS remains a stable and beloved choice for many enthusiasts.

On the other hand, Tailscale sets up a secure and private VPN environment by creating secure, peer-to-peer connections among your devices. It’s perfect for avoiding the risks associated with traditional VPN setups that require exposing router ports to the internet.

Preparing Your Raspberry Pi

To begin, ensure your Raspberry Pi is set up and connected to the internet. Ideally, you should be using a model with sufficient RAM, such as the 8GB variant, to ensure smooth performance.

Installing Docker

Before we can proceed with CasaOS, Docker must be installed on your Raspberry Pi. You can find a detailed installation guide in a previous article. Docker serves as a container management service required for both CasaOS and Tailscale installations.

Installing CasaOS

1. Open a Terminal Session: Start by logging into your Raspberry Pi via SSH.
2. Run the Installation Command: Previously, CasaOS automatically installed Docker, but this has changed since Docker’s update. Ensure Docker is pre-installed before running the following command:

curl -fsSL https://get.casaos.io | sudo bash

curl -fsSL https://get.casaos.io | sudo bash

3. Access CasaOS Interface: After installation, access the interface through the provided local IP address and port. Set your username and password to begin managing your Raspberry Pi with CasaOS.

Handling Docker Container Conflicts

When using CasaOS with pre-existing Docker containers, be mindful of compatibility issues. CasaOS might attempt to tweak these containers for integration into its dashboard, potentially altering configurations.

Setting Up Tailscale

Tailscale Installation Overview

Tailscale will be set up using a Docker container. It facilitates creating secure networks across devices without exposing your internal network.

1. Docker Compose Configuration: Tailscale is installed using a Docker Compose file that defines how Docker containers are built and run.
2. Authentication Key Creation: Create an authentication key via the Tailscale website following these steps:
   • Go to “Settings” -> “Keys” on Tailscale’s site.
   • Generate a reusable auth key corresponding to your Raspberry Pi setup.

version: '3'
services:
  tailscale:
    image: tailscale/tailscale:latest
    container_name: tailscaled
    restart: unless-stopped
    network_mode: host
    cap_add:
      - NET_ADMIN
      - NET_RAW
    volumes:
      - /var/lib/tailscale:/var/lib/tailscale
      - /dev/net/tun:/dev/net/tun
    environment:
      - TS_AUTHKEY=tskey-auth-ab1CDE2CNTRL-0123456789abcdef
      - TS_ACCEPT_DNS=true # Optional: accepts DNS configuration from the admin console

version: '3'
services:
  tailscale:
    image: tailscale/tailscale:latest
    container_name: tailscaled
    restart: unless-stopped
    network_mode: host
    cap_add:
      - NET_ADMIN
      - NET_RAW
    volumes:
      - /var/lib/tailscale:/var/lib/tailscale
      - /dev/net/tun:/dev/net/tun
    environment:
      - TS_AUTHKEY=tskey-auth-ab1CDE2CNTRL-0123456789abcdef
      - TS_ACCEPT_DNS=true # Optional: accepts DNS configuration from the admin console

3. Running Docker Compose: Use SSH to run the command docker compose up -d after saving your Docker Compose configuration, ensuring your containers are active and functioning.

Verifying Tailscale and CasaOS Status

Access the Portainer dashboard or respective command-line interfaces to verify the status of your Docker containers, ensuring both Tailscale and CasaOS are running perfectly.

Real-Time Use Cases and Benefits of Tailscale

• Home Network Security: With Tailscale, establish a VPN that keeps your personal network secure from vulnerabilities traditionally encountered with port forwarding.
• Remote Access and Off-Site Backups: Leverage Tailscale’s secure connections to facilitate off-site data backups or to access your home network remotely, replicating a local connection.
