Containers are the default path to prod. That also makes the supply chain a major risk. At Devoxx UK, the interest in Docker Captain @maeddes.bsky.social’s Docker Hardened Images talk was a clear signal that devs are actively looking for better ways to handle container security.

The countdown to @devoxx.uk is officially in the "getting real" phase. From the latest in #Java & #CloudNative to the cutting edge of #AI agents, the vibes are going to be immaculate. Who are you most excited to see on stage? 👇 devoxx.co.uk

You deploy across clouds like it’s second nature. Docker listens, Kubernetes obeys, and somehow it all just works.

Very interesting talk if you're building container images - especially for the JVM. I had not really explored buildpacks for this. Definitely gave me some things to think about
