Synology NAS Docker Guide: Practical Apps for IT Teams

How to Use Synology NAS and Docker for Business Apps

Using containers to run business apps is a good way to make deployments more consistent, cut down on server sprawl, and keep services portable between environments. The Synology Container Manager interface is usually used to manage Docker workloads on Synology NAS. It has common options like container networking modes and bridge networks, as well as a guided UI for images, projects, and resource settings.

This guide is all about step-by-step container deployments that IT teams can use, as well as storage, backup, and security practices that are important in the real world.

Set a Stable Foundation Before You Deploy

1) Choose the best way to store things

Make a special shared folder, like /volume1/docker/, and put each service in its own subfolder. For example, /volume1/docker/npm/, /volume1/docker/vaultwarden/, and /volume1/docker/uptimekuma/. This makes permissions easier to manage and makes backup and migration easier.

2) Make use of a separate service account

Don’t run containers as an administrator. Make a DSM user like svc-containers, give it access to only the folders it needs, and use that identity to own files on mapped volumes when you can.

3. Make a decision about networking ahead of time

Bridge networking works for most apps. Depending on how you set things up, you can either expose ports directly or use host networking for reverse proxies and “frontend” services. You can choose between bridge networks or host networking with Container Manager.

Advice on how to run things

Limit access to the admin UI (port 81) to IPs you trust, or put it behind a VPN.

For administrators, use strong admin credentials and turn on MFA in DSM.

Keep certificates automated, but make sure you have a written plan for renewing them and switching to a backup.

Tips for staying safe

1. Turn off open signups unless you really need them.
2. Only publish it over HTTPS, and if possible, through the reverse proxy.
3. Add DSM firewall rules to stop direct access to open ports.

Best way to do things

Keep an eye on both the application URL and the NAS health surface area. This includes the reverse proxy endpoint, DNS resolution, and a path to a backup repository.

Synology explains how it fits into the solution

Synology NAS is a great choice for containerized business services because it combines storage, identity controls, snapshots, and container operations into one platform. This lets IT teams run internal apps close to protected data while controlling network exposure through DSM firewall rules, bridge or host networking choices in Container Manager, and resilient storage designs that support recoverability and predictable performance.

Backing up and restoring containerized apps

You can throw away containers, but your data will stay. Use the mounted volume of each app as the recovery target.

Take a snapshot of the /volume1/docker/ share on a regular basis so you can quickly roll back.

Make copies of the same datasets in a different place, like another NAS, a cloud target, or a second location.

Every three months, test restores by starting the Compose project on a different host and checking logins, databases, and encryption keys.

About the Epis technology

As part of a larger IT infrastructure and data protection strategy, Epis Technology helps businesses set up and maintain Synology-based container environments. Their team makes storage layouts that can grow with the business, makes NAS and network access more secure for remote work, and makes sure that containerized services work with backup and business continuity goals. Epis Technology also backs up Microsoft 365 and Google Workspace, offers large storage solutions, and fully manages PC backups. This way, all of your containers, endpoints, and SaaS data are protected by the same resilience plan.
