 # Rocky SSH Container
+## Setup
+### SSH Keys
+Place your SSH public keys in the `docker_build/ssh-keys/` directory:
+```bash
+cp ~/.ssh/id_ed25519.pub docker_build/ssh-keys/
+```
+The container will automatically add all `.pub` files from this directory to `/root/.ssh/authorized_keys`.
+
+## Building Containers
+### Base Development Container
+```bash
+# From the dev_env directory
+podman build -t rocky_dev:latest -f docker_build/Dockerfile .
+```
+### GPU-Enabled Container
+The GPU container builds on top of the base container using multi-stage build:
+```bash
+# First build the base container (from dev_env directory)
+podman build -t rocky_dev:latest -f docker_build/Dockerfile .
+# Then build the GPU version
+podman build -t rocky_dev_gpu:latest -f docker_build/Dockerfile.gpu .
+```
+
+## GPU Support
+The GPU-enabled container includes:
+- NVIDIA Container Toolkit for GPU access
+- GPU test script at `/usr/local/bin/gpu-test.sh`
+- Environment variables configured for NVIDIA GPU visibility
+- Workspace directory at `/workspace` for GPU workloads
+
+### Running with GPU Support
+```bash
+# Run GPU-enabled container
+podman run -it --device nvidia.com/gpu=all rocky_dev_gpu:latest
+# Test GPU inside container
+gpu-test.sh
+nvidia-smi
+```
