Not everyone wants to rely on public cloud services, especially if they're working on development tasks or need encrypted file transfer. Running a private cloud is one way to accomplish this need for security and data ownership, but setting up all the necessary parts is complex. That's where cloud OS systems come in. The infrastructure is in place for you to work in, so you have less setup time but can keep data ownership throughout the process.

Think of it as a home lab in the cloud, and you're not far off. CasaOS is one of the most well-known options. But I've been using a different system, HomeDockOS, and what I've seen so far is incredibly encouraging. It's a cloud-first operating system that manages containerized services but in a familiar desktop environment, and I've been enjoying every minute of using it.

What is HomeDockOS, and what can it do

Become the cloud with this self-hosted operating system

HomeDockOS is your own personal cloud, with a cloud OS built on Linux that helps manage Docker containers from a nice interface. It's similar to CasaOS in that regard, except you can share files of up to 1 gigabyte securely, and the app store has a ton of containers to be getting on with. It has encrypted storage and a native desktop app for Windows and macOS, and it runs on anything from a Raspberry Pi to a server.

Using the company's cloud servers gives you hosting, SSL for your whole stack, hostname customization, and more. But you can self-host if you prefer, using Windows Subsystem for Linux which is limited to Windows 10 Pro or Windows 11, macOS, or your favorite Linux distribution.

It has some fantastic features that make using it simple, including an app store that works as an automated GUI to install Docker containers and fill in their necessary compose files, plus some things you might not expect.

• Automated updates direct from GitHub
• Shield Mode to guard against suspicious access attempts
• Encrypted login system that dynamically creates RSA key pairs on each system restart
• Drop Zone file encryption
• Server fingerprint obfuscation to mislead bots and fingerprinting system

The installation process is painless, with one-line scripts for most operating systems, and an automated installer for Windows that sets up WSL and all the prerequisites for you, so all you need to do is sit back and wait. What really sets this apart from other platforms is that a huge part of the security setup is done for you by default, without having to sort out your own SSL, reverse proxies, and other things that not everyone knows how to do at first. I appreciate that even though I know how to set those things up, I can spin up containers faster without having to do drudge work.

You can subscribe to its cloud version if you prefer

Just because you can self-host something doesn't mean you always should, and HomeDockOS takes some of the maintenance out of the way if you let them do the hosting. You get a dashboard like any other VPS provider, the ability to customize your domain name without having to pester support, automatic SSL certificates, automated backups, and a support team in case you need their aid.

At this stage, the subscriptions for the cloud-hosted options fund the development, and the source code is visible but not fully open source. The team plans to transition to an OSI-approved license at a future stage when HomeDockOS is financially sustainable, which is a commendable and shrewd business decision.

The App Store is a fancy Docker GUI

Containers confuse me, this doesn't

One of the things that bugs me about Docker is that you need to learn a lot of new terminology and ways of doing things before you can actually do them. HomeDockOS simplifies this, with each app in the store being a visual frontend for installing and setting up the Docker container for that service.

So, clicking on installation for Syncthing, for example, gives you a simplified set of form fields already filled in for ports and volumes, and a dropdown for restart policy. You can change the ports or install folders if you want, or click the toggle to see the full Docker Compose file that will be used. I like this approach, both from a learning perspective and a user experience design lens. I can use the GUI for a quick install, or see how it works with Docker for use on other systems, and flip between the two at will.

With a few clicks, your container is accessible from the browser on your computer, and you can quickly make it accessible from anywhere. The App Store does all the background setup, including adding [[HD_USER_NAME]] or any other local variables needed. All you have to do is create the user account for each service as you would normally.

You can manually import other containers, but it's a bit rough

You're not technically limited to the containers in the App Store, but getting them into HomeDockOS is currently a bit of a headache. The developers have a workaround, which is easiest to do if you're running the OS on a Linux system—install the services manually with Docker, and they will show up in the HomeDockOS dashboard.

You can also use Control Hub > Import and manually bring a Docker Compose file into HomeDockOS, which works but isn't as polished as the rest of the system. The team is working on a way to add services from outside the App Store, which is great news and will make this even better for self-hosting converts.

And the future roadmap is rosy

Including a dynamic reverse proxy with user-level access controls

The developers of HomeDockOS are involved in the self-hosted community on Reddit and appear receptive to input, criticism, and any other feedback. A dynamic reverse proxy system with user-level access controls and multi-user logins for the cloud-hosted option is coming. An add-to-store feature is planned so that developers can add their apps easily, and share what they've built. They're also working on an automatic port checker so that installing things like Nginx, which takes over port 80, won't restrict your access to the system.

HomeDockOS lets you self-host the cloud with ease

For a newcomer to the world of Docker, sometimes Docker Desktop, Portainer, or Podman can be a little intimidating. But HomeDockOS looks and feels like a normal operating system with an app store that you access with clicks, not arcane code words in Docker Compose files. You don't see them unless you look, and it provides a friendly way to get used to how containers operate. Once the future roadmap is in place, it will be just as powerful as other Docker managers, but with a nicer interface and security by default. And that's important, even if you're only self-hosting on your home network.
