NebulaPod is a Docker implementation written in Python that allows you to pull Docker images from Docker Hub and execute commands within them. This project is designed to provide a lightweight and efficient alternative for running containerized applications without the need for a full-fledged container runtime.

• Docker Image Execution: Run commands inside Docker images pulled from Docker Hub.
• STDOUT and STDERR Handling: Capture and display standard output and error streams.
• Exit Code Handling: Properly handle and return exit codes from executed commands.
• Filesystem Isolation: Enhance security by isolating the filesystem for each container.
• Process Isolation: Isolate processes within the container for improved resource management.
• Docker Registry Support: Fetch Docker images from any Docker registry.

Python 3.6 or higher

Clone the repository and navigate to the project directory:

git clone https://github.com/<your-username>/NebulaPod.git
cd NebulaPod

You can now execute your program like this:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer echo hey

For handling exit codes:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer exit 1

For isolating files:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer ls /some_dir

for isolating process:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer mypid

for fetching an image from the Docker Registry:

mydocker run ubuntu:latest /usr/local/bin/docker-explorer exit 1
