Docker File System Extractor

A small Bash script to extract the complete filesystem from an OCI/Docker image layout.

Useful when you want to inspect image contents without running the container.

---

🚀 Usage

1. Save a Docker image to a tarball:

   docker save IMAGE_NAME -o image.tar

2. Extract the image tarball:

   mkdir image_contents
   
   tar -xf image.tar -C image_contents

3. Run the extractor:

   ./docker-image-extractor.sh /path/to/image_contents /path/to/output

📂 Example

docker pull alpine:latest

docker save alpine:latest -o alpine.tar

mkdir alpine_contents

tar -xf alpine.tar -C alpine_contents

./docker-image-extractor.sh alpine_contents alpine_rootfs

Now you can inspect the full Alpine filesystem inside ./alpine_rootfs.
