Learning Lab for September 2025 about using the static Chainguard container images

The September 2025 Learning Lab, led by Adrian Moat, focuses on minimizing the attack surface of container images by adopting Chainguard’s static and minimal images, which boast zero known CVEs. Adrian demonstrated a container build for a Go-based application and explains more complex use cases.
