If you're running Nextcloud on Docker, there's a good chance you want more than just file syncing. One of the biggest advantages of self-hosting is the ability to expand and personalize your setup. With the right combination of containers and installable Nextcloud apps, you can turn your Nextcloud instance into a robust personal cloud platform that’s fast, flexible, and easy to manage. These six containers bring features and performance enhancements that integrate seamlessly with Nextcloud.

6 OnlyOffice for collaborative editing

Real-time document editing inside Nextcloud

OnlyOffice adds powerful document-editing capabilities to your Nextcloud server. It allows users to collaborate on text files, spreadsheets, and presentations directly within the Nextcloud web interface. Changes appear in real time, and formatting is preserved across different platforms. This makes it ideal for teams or households that want to work together without relying on third-party cloud services.

Deploying the OnlyOffice Document Server via Docker is straightforward. The container is well-maintained and supports customization through environment variables. You’ll need to remove Collabra and the Nextcloud Office app to avoid conflicts, but once it’s done, the integration feels seamless. Documents open quickly, and the interface is intuitive even for those used to Microsoft Word or Google Docs.

There are some hardware considerations, especially for ARM-based setups like Raspberry Pi, where performance may be limited. OnlyOffice works best on systems with at least 2GB of RAM and supports SSL out of the box. With minimal setup effort, it becomes a reliable and essential component of a Nextcloud-centric productivity suite.

5 Redis for faster performance

Speed up your Nextcloud database operations

Redis is a key-value store that acts as a memory cache backend for Nextcloud. It helps reduce the load on your database by storing frequently accessed data in memory. This speeds up response times across the board, especially for large installations or busy multi-user environments. Even small home servers can benefit from Redis, gaining smoother performance and faster page loads.

Running Redis in Docker is straightforward and requires minimal configuration. If you've installed the Nextcloud All-In-One package, chances are it's already installed. If not, it's easy enough to install in Docker and link it directly to your Nextcloud container using Docker Compose. After adding a few lines to your config.php, Nextcloud will start using Redis for memory caching and file locking. These changes often lead to noticeable improvements in daily use.

File locking is a crucial Redis feature for collaborative setups. It prevents data corruption by ensuring that two users aren’t writing to the same file simultaneously. Without Redis, file locks default to the database, which can be much slower. Whether you have a single-user instance or a multi-user network, Redis is a valuable performance boost.

4 Traefik as a reverse proxy

Handle SSL and domain routing with ease

Traefik is a dynamic reverse proxy that excels in containerized environments. It automatically detects services running in Docker and configures routes for them, handling HTTP, HTTPS, and WebSocket traffic with minimal input. One of its standout features is the ability to issue and renew Let’s Encrypt SSL certificates automatically. That takes the hassle out of setting up secure access to your Nextcloud instance.

With Traefik, adding services like Nextcloud becomes a matter of labeling containers. You define the rules in your Docker Compose file, and Traefik does the rest. There’s no need to restart the proxy or manually update configuration files. If you’re running multiple services, such as OnlyOffice, Uptime Kuma, or Home Assistant, Traefik keeps everything organized and reachable under clean, secure domains.

It also features a built-in dashboard, providing a visual overview of active services and routers. For Nextcloud, this means HTTPS, WebSocket routing, and even rate limiting or IP whitelisting if needed. You’ll save time with setup and reduce complexity in the long run. It’s a brilliant addition to any Docker-based server.

3 Watchtower for automatic updates

Keep your containers secure and up to date

Watchtower brings automated updates to your Docker containers, monitoring for new image versions and restarting services when an update is available. This helps you stay current without having to check for and pull the latest tags manually. For users who value simplicity and security, Watchtower reduces the maintenance burden while keeping your setup fresh.

You can run Watchtower as its own container with access to the Docker socket. It periodically scans running containers, checks for new versions of their images, and performs a clean shutdown and restart when needed. You can configure update intervals, logging, and even receive notifications when updates occur. That level of automation fits nicely in a self-hosted environment.

Still, there’s room for caution. Some containers, especially those with complex configurations like Nextcloud, may require some manual testing before applying updates. You can label specific containers to exclude them from Watchtower’s update cycle. Even with a few manual holds, the time saved and peace of mind gained from automated updates make Watchtower a strong addition to any Docker stack.

2 BorgBackup for reliable encrypted backups

Secure and efficient data snapshots with versioning

BorgBackup is a powerful and flexible backup tool that works exceptionally well in Docker environments. It’s a great match for Nextcloud because it supports deduplication, compression, and encrypted backups. With Borg, you can take efficient snapshots of your Nextcloud data and store them locally, on remote servers, or in cloud buckets via rclone. It helps ensure your data stays safe without wasting space.

Running Borg in a container is straightforward and gives you control over schedules and destinations. You can mount the same volumes used by your Nextcloud container to make the data available to Borg during backups. Adding a scheduling tool like cron or using a supervisor container helps automate regular backups without needing manual intervention. For remote storage, pairing Borg with rclone lets you push encrypted backups to almost any service.

Borg also makes restores simple, whether you’re recovering a single file or the entire data folder. Unlike some GUI-based tools, it gives you transparency and control over the entire process. You can script everything, check logs, and test recovery steps periodically. With Nextcloud Backup now incompatible with newer versions, Borg is a reliable and well-supported alternative that many self-hosters trust for long-term backup strategies.

1 Tailscale for secure remote access

Private VPN access to your Nextcloud server

Tailscale offers a mesh VPN built on WireGuard that gives you private and encrypted access to your Nextcloud server from anywhere. Instead of opening ports to the internet, you create a secure tunnel that only your authorized devices can use. This keeps your Nextcloud instance isolated while still being fully accessible on your laptop, phone, or other remote machines.

Deploying Tailscale in Docker is a lightweight and efficient approach. Once authenticated, your container joins your personal network and is assigned its own static IP address. You can then route traffic to Nextcloud as if you were on the same LAN, without touching your router or setting up port forwarding. It’s an excellent solution for home labs or privacy-focused setups.

Tailscale’s admin console lets you manage access, revoke devices, and set policies with ease. You can also restrict access to specific IP ranges or subnet routes if necessary. For users who travel or work remotely, Tailscale offers a secure and seamless way to stay connected to your Nextcloud server without exposing it to the open web.

Expand your setup without adding complexity

Each of these containers fills a specific role that helps Nextcloud shine. Whether you're improving speed with Redis, enhancing security with Tailscale, or simplifying updates with Watchtower, Docker makes the integration painless. A well-curated container stack transforms Nextcloud from a simple file sync service into a full-featured personal cloud. With the correct setup, you can build a system that’s powerful, secure, and easy to maintain.
