⚙️ Nucleus - Run Containers with Less Overhead

🚀 Getting Started

Nucleus is a small container engine built in Rust. It runs Linux containers with a focus on speed, low resource use, and tight system control.

If you want a simple way to run containerized apps on Windows, start here:

1. Visit the Nucleus Releases page
2. Download the latest Windows release file
3. Open the file and follow the setup steps
4. Start Nucleus and load your container

📥 Download and Install

To download Nucleus, go to the Releases page.

On that page:

1. Find the latest release at the top
2. Open the Assets section
3. Download the Windows file for your system
4. Save it to a folder you can find again, such as Downloads or Desktop

After the download:

1. Open File Explorer
2. Go to the folder with the file
3. Double-click the file to start it
4. Follow the on-screen steps until setup ends

If Windows asks for permission, choose the option that lets the app run.

🖥️ What Nucleus Does

Nucleus helps you run container-based apps in a controlled way. It is built for users who want a lean tool instead of a heavy system.

It is a good fit for:

• Small servers
• Edge devices
• Local testing
• Embedded Linux systems
• Workloads that need low memory use
• Apps that need strong process isolation

✨ Main Features

• Fast startup time
• Small memory use
• Container support for Linux workloads
• Support for modern Linux kernel features
• Isolated process handling
• Storage support for layered file systems
• Works well with resource limits
• Built in Rust for speed and safety

🔧 System Requirements

Nucleus works best on a system that supports modern container features.

Recommended setup:

• Windows 10 or Windows 11
• 64-bit processor
• At least 4 GB of RAM
• 500 MB of free disk space
• Virtualization turned on in BIOS or UEFI
• Internet access for the download

For best results, use a system with:

• A recent CPU
• SSD storage
• Windows updates installed
• Admin access for setup

🧭 First Run

After installation, open Nucleus from your Start menu or desktop shortcut.

Then:

1. Launch the app
2. Let it finish its first setup
3. Choose or load a container image
4. Start the container
5. Check the status screen for the running process

If you keep your files in a custom folder, point Nucleus to that path during setup.

📦 Basic Use

Nucleus keeps the flow simple.

Typical use looks like this:

1. Download the app
2. Open it
3. Pick a container image
4. Start the container
5. Stop it when you are done

If you use images often, keep them in one folder so you can find them fast.

🛠️ Common Tasks

▶️ Start a container

Open Nucleus and choose the container you want to run. Click the start action and wait for the status to change to running.

⏹️ Stop a container

Select the running container and choose stop. Wait for the process to shut down cleanly.

🗂️ View logs

Use the logs view to check what the app is doing. This helps when a container does not start.

♻️ Restart a container

If an app stops responding, restart the container from the main screen.

🔒 Security and Control

Nucleus uses Linux isolation tools to keep apps separated. This helps reduce risk when you run more than one service on the same system.

It is designed to work with:

• Process namespaces
• Resource limits
• File system isolation
• Container root switching
• Kernel-backed controls

These parts help Nucleus keep each container separate from the rest of the system.

🧪 Good Uses

Nucleus works well for:

• Small web services
• Test apps
• Local development
• Home lab systems
• Compact edge systems
• Server tasks that need low overhead

🧰 Troubleshooting

The app does not open

• Check that the download finished
• Run the file again
• Make sure Windows did not block it
• Try launching it as an administrator

The container does not start

• Check that virtualization is enabled
• Make sure your image is valid
• Confirm that the container file path is correct
• Look at the log view for error text

The app feels slow

• Close other large apps
• Make sure you have enough free memory
• Store container files on an SSD
• Use a smaller image if possible

The download does not start

• Refresh the Releases page
• Try another browser
• Check your network connection
• Save the file to a local folder first

📁 File Layout

A typical Nucleus setup may include:

• App files
• Container images
• Logs
• Config files
• Runtime data

Keep these files in one place so you can back them up later.
