Advanced Docker Topics

Beyond the basics, Docker supports advanced use cases such as GUI applications, multi-architecture builds, GPU acceleration, and system-level debugging. Mastering these topics enhances your ability to use Docker in complex, real-world environments.

Running GUI Applications in Docker

Linux GUI apps can be run in containers using X11 forwarding:

docker run -e DISPLAY=$DISPLAY \
    -v /tmp/.X11-unix:/tmp/.X11-unix \
    gui-app-image

For Windows or macOS, tools like VNC or XQuartz are used to view GUI apps from containers.

Debugging Containers

Use interactive shell access to inspect containers:

docker exec -it container_name /bin/bash

Use logging tools and inspect commands to trace issues:

docker logs container_name
docker inspect container_name

Multi-Arch Builds (ARM & x86)

Use Docker Buildx to build for multiple architectures:

docker buildx create --use
docker buildx build --platform linux/amd64,linux/arm64 -t myapp:multiarch --push .

This allows you to support both desktop and ARM devices like Raspberry Pi.

Using Docker with GPU (for AI/ML)

Enable NVIDIA GPU support with Docker using the nvidia-container-toolkit:

docker run --gpus all nvidia/cuda:11.8.0-base nvidia-smi

Great for machine learning, deep learning, or GPU-intensive applications.

Windows Containers vs. Linux Containers

Windows containers can only run on Windows hosts (or Windows Server Core base images)
Linux containers are portable across environments and more widely supported
Use Docker Desktop to switch between Linux and Windows container modes

These advanced features unlock Docker’s full potential for enterprise systems, development pipelines, and high-performance computing. Explore these capabilities to scale your infrastructure intelligently.
