Nextcloud All-in-One with Tailscale Integration

This project sets up a Nextcloud All-in-One instance with Tailscale VPN integration using Docker Compose. It creates a secure, private network connection for your Nextcloud All-in-One instance using Tailscale.

Prerequisites

• Docker and Docker Compose installed on your system
• A Tailscale account and auth key (get one from https://login.tailscale.com/admin/authkeys)
• Basic understanding of Docker and networking concepts

IMPORTANT NOTE

Unlike most of the the other deployments in this organization the data for the service is managed with a docker volume instead of in this project directory structure. This was a requirement for nextcloud and any PRs or help via issue is welcome.

Setup Instructions

1. Clone the Repository

   git clone https://gitea.damconsulting.llc/DAM/ts-nextcloud-all-in-one.git
   cd nextcloud-aio
   

2. Create Required Directories

   mkdir -p tailscale/tailscale-data
   

3. Configure Tailscale

   • Replace {{YOUR_TAILSCALE_AUTHKEY}} in the docker-compose.yml with your actual Tailscale auth key
   • Optionally, update the file in tailscale/config/serve.json if you need specific Tailscale serve configurations
     • CAUTION: Changing "${TS_CERT_DOMAIN}:443": false to true will expose the service to the internet

4. Configure Nextcloud All-in-One

   • See the README in the Repo for configuration options

5. Start the Services

   docker compose up -d
   

6. Wait for Certificate to propagate [~2m]

7. Login to master container for initialization

   • After starting the services the service admin page should be available via tailnet at https://nextcloud-aio.{{YOUR_TAILNET_DOMAIN}}.ts.net:8443 ie https://nextcloud-aio.tail12345.ts.net:8443

8. After configuration go to https://nextcloud-aio.{{YOUR_TAILNET_DOMAIN}}.ts.net to access your instance.

9. God speed with the rest of the config.

Services

nextcloud-all-in-one-ts (Tailscale)

• Runs Tailscale VPN client
• Image: tailscale/tailscale:latest
• Container name: nextcloud-all-in-one-ts
• Hostname: nextcloud-all-in-one
• Requires NET_ADMIN and SYS_MODULE capabilities
• Persists state in ./tailscale/tailscale-data
• Uses configuration from ./tailscale/config

nextcloud-all-in-one

• Depends on nextcloud-all-in-one-ts service

Usage

• After starting the services your service should be available via tailnet at https://nextcloud-all-in-one.{{YOUR_TAILNET_DOMAIN}}.ts.net ie https://nextcloud-all-in-one.tail12345.ts.net/
• To manually get the Tailscale IP/hostname of your container:

  docker logs nextcloud-all-in-one-ts
  

  Look for the Tailscale IP address in the logs.

Optional Features

• Stopping the Services

  docker compose down
  

Troubleshooting

• Check container logs:

  docker logs nextcloud-all-in-one-ts
  docker logs nextcloud-all-in-one
  

• Ensure your Tailscale auth key is valid and not expired
• Verify the configuration files have proper permissions
• Make sure required directories exist before starting

Notes

• Direct port mapping is disabled by default as Tailscale handles the networking
• Services restart automatically unless explicitly stopped
