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

Setup Instructions

Clone the Repository

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

Create Required Directories
```
mkdir -p tailscale/tailscale-data
```
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
Configure Nextcloud All-in-One
- See the README in the Repo for configuration options
Start the Services
```
docker compose up -d
```
Wait for Certificate to propagate [~2m]
Login
- 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/

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

Uncomment and adjust the ports mapping if you need direct access (without Tailscale):
```
ports:
- 3000:3000
```
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

The Nextcloud All-in-One service uses the Tailscale service's network stack via network_mode: service:nextcloud-all-in-one-ts
Direct port mapping is disabled by default as Tailscale handles the networking
Services restart automatically unless explicitly stopped
