Why is docker taking so much space?

# List all images sorted by size (largest first)
docker images --format "table {{.Repository}}\t{{.Tag}}\t{{.Size}}" | sort -k3 -hr

# Get total disk usage breakdown
docker system df -v

# Container disk usage
docker ps --size



# Remove dangling images
docker image prune -f

# Remove unused containers, networks, images
docker system prune -a --volumes

# More aggressive - remove all unused (CAREFUL!)
docker system prune -a --volumes -f
